【推荐2】Amyotrophic lateral sclerosis, more commonly known as ALS, affects the nerve cells in the brain and spinal cord (脊髓) that make the muscles of both the upper and lower body work.

Those nerve cells lose their ability to control muscle movement, which leads to paralysis (瘫痪) and death. Its most famous sufferer was famed physicist Stephen Hawking, who died on March 14, 2018 at the age of 76.

Hawking, diagnosed with the condition in 1963, lived with it for more than 50 years — a remarkably long time for an ALS sufferer. The disease left him paralyzed and completely dependent on others and technology for everything: bathing, dressing, eating, mobility and speech. He was able to move only a few fingers on one hand.

“I try to lead as normal a life as possible, and not think about my condition, or regret the things it prevents me from doing, which are not that many,” he wrote on his website.

“I have been lucky that my condition has progressed more slowly than is often the case. But it shows that one need not lose hope.”

Hawking’s life, including his battle with ALS, was made into a 2014 biopic, The Theory of Everything, starring Eddie Redmayne.

The US Centers for Disease Control and Prevention says that 20,000 to 30,000 people have ALS in the United States, with about 5,000 new cases diagnosed every year. People usually find out that they have it between 55 and 75 years of age. On average, patients live two to five years after symptoms develop.

For reasons not yet understood, military veterans are twice as likely to be diagnosed with ALS as the general public, according to the ALS Association. Scientists have been studying many factors that could be linked with ALS, such as heredity (遗传) and environmental exposures.

【推荐3】Since the novel corona-virus (新冠病毒) outbreak, many people have been forced to stay at home for long periods of time to protect themselves from the virus. This has given people more free time to learn new skills and find different ways to entertain themselves.

Some of these activities include things like singing, learning to cook and ordering fresh food online. All of these things can be done in the palm of your hand with mobile apps.

Before, young people would go outside and meet friends at karaoke bars (卡拉OK酒吧). Now, friends can meet and sing on the mobile karaoke app Changba. “The Changba app not only gives me the chance to share my songs with friends, but also lets me sing whatever I like at home.” said an app user.

Some people have also taken up cooking as a new hobby to pass the time. You don’t need to attend culinary (烹饪的) school, thanks to apps like Xiachufang and Ecook, which make it easier for those who want to learn how to cook. These apps provide a platform for users to look up different recipes (菜谱) and to share their own recipes with others. “Using this app, I have learned many new and healthy dishes which help me eat better.” an app user commented on the app’s website.

To help people avoid crowded places like grocery stores, apps that deliver (递送) goods right to your door have also become very popular. “It is obvious that the epidemic (疫情) has attracted new groups of consumers (消费者), such as elderly people, who originally didn’t belong to our target user group.” Zhang Yi, an analyst from the market research company, said.

Indeed, during this special time, these apps have opened up a whole new world of opportunities for people of all ages and backgrounds.

【推荐1】In recent years computer scientists have come up with several different ways of creating false videos of people using Artificial Intelligence (AI). These videos are usually called “deepfakes”. Some deepfakes work by putting the face of one person onto a different person in a video. Others work by taking an existing video of a person and changing it so that the person says or does something they didn't say or do.

At first, creating deepfakes was complex. It required special knowledge, hundreds of pictures of the person who was being faked, and lots of time. Now it's much simpler. There are websites and apps that allow almost anyone to create deepfakes. An app recently came out which allowed users to put their faces into famous movie scenes. The process lakes about eight seconds, requires one picture, and can be done on a mobile phone. One group of computer scientists created a program that allowed them to edit the words conning out of someone's mouth in a video just like you might edit a document on the computer.

It's one thing to swap the faces of famous actors. But what happens if someone puts out a fake video of a politician, for example, making it look like they broke the law? There's also the problem of the time it takes to figure out that something is fake. Even if a video is proven to be fake, it could be too late. Millions of people might have already seen and believed it. On the other hand, what happens if a video is actually real, but people don't trust it because they're told it's a deepfake?

Many deepfakes are so good that only another AI system can tell that they're fake. Experts are working hard to create new AI tools that can identify faked videos. Many people are confident that people can defeat deepfakes soon. However, personally, it is very challenging because this technology has always fallen behind the deepfakes.

【推荐2】The Consumer Technology Association, formerly called The International Consumer Electronics Show, or CES, believes about 170, 000 people will attend the show. About one-third of them are reported to come from countries besides the United States.

More than 4, 000 businesses will show products used through the Internet such as gaming, self-driving cars, artificial intelligence（人工智能）and robotics. One of the biggest stars at CES this year is the voice-controlled digital （数字的）assistant. While the technology is not new, many companies will show off the latest digital assistants.

Equipment controlled by digital assistants, especially those turned on by voice, were already big sellers in 2017. This year, Google, Amazon and Apple are expected to release even more products to keep up with the rising demand.

Digital assistants are powered by artificial intelligence and machine learning technology. They are designed to learn users' preferences over time and then “think" and act on their own. Some of the biggest developments in technology have come in the area of home automation （自 动化）. Amazon Echo, Google Home, Apple's Home Pod and Microsoft's Cortana are a few examples of voice-controlled equipment. All include smart speakers that “talk" to users inside the house and can perform operations.

Experts with the Consumer Technology Association say sales of smart speakers are expected to nearly double in 2019.

The Internet-linked products can play music or find information when asked questions. They can also control equipment such as lighting, cameras, televisions and temperature controllers. Among new “smart" home products to be released at the CES are voice-controlled washing machines, refrigerators, showers and toilets. There is also much new physical fitness and health-related equipment on show. Some are designed to help people create the best personal fitness plans to reach their goals.

【推荐3】Mass communication has been growing and affecting the way communities and people behave. At every stage of the development of communication, from the telegraph to the Internet, societies have had to adapt to its effects. But have the effects been more positive or negative?

The saying “knowledge is power” has been an excellent motivator for people to improve their lives, but today the massive amount of information available through the Internet doesn't always seem to be helping people in the way we’d hoped. Rather than improving people’s lives and bringing us closer together, the information age is making us more divided and irresponsible.

Nevertheless, many people find comfort in their virtual (虚拟的) worlds and are happy to connect with real-life friends and online friends from the familiar surroundings of their living rooms. However, being able to reinvent themselves online and be whoever they want to be leads to the question of whether they are losing their identities by living in a virtual world. It's not all bad news, however. Mass communication has helped change some attitudes for the better. Take our views on the environment for example. Internet campaigns by governments and other organizations have helped popularize the ideas of recycling, protecting wildlife and reducing pollution.

Modern electronic communication now influences every aspect of our lives - it is a powerful tool that has raised some concerns for society. However, it has also brought countless benefits to society. At the end of the day, it can be used both for good or evil, which largely relies on the morals and sense of responsibility of the individual or community involved. In short, it needs to be used with care.

What does the text mainly talk about?

A．The comfort of the virtual worlds.

B．The effects of mass communication.

C．The development of mass communication.

D．The way to use modern mass communication.

【推荐1】When you look in the mirror, you see yourself. That puts you in the company of animals like dolphins, elephants and chimpanzees. The mirror test is often used as a way of measuring whether animals have self-awareness. And an animal that is aware of itself has a high level of intelligence. Now, a species of fish - the cleaner wrasse - has also spotted its reflection.

Alex Jordan, a biologist at the Max Planck Institute in Germany, is one of the researchers of the study on cleaner wrasse consciousness. He and his team conducted many tests that show the fish does seem to recognize its reflection - when the researchers added a colored mark to its body, the fish would even try to remove the mark upon catching sight of it in the mirror. It seems to indicate the clever fish species has some sense of self or individuality.

But Jordan said, “I’m the last to say that the cleaner wrasse is as smart as chimpanzees.” Instead, he believes that the measure scientists have used for nearly 50 years is imperfect.

One problem with the test, for example, is that it uses vision to measure self-awareness. Yet not all animals rely on sight to recognize themselves. It may well be that a bat, for example, which depends on sonar (声波定位) to get around, is self-conscious. Elephants, while able to pass the mirror test, rely more heavily on smell than on sight.

Consciousness in humans or animals is not easy to measure or understand. Philosophers and scientists have long wrestled with the questions of how a sense of self is assessed, and how it relates to physical processes. Jordan believes the cleaner wrasse is self-cognizant (自我知晓的), but not the same extent (程度) as a human. This means scientists need to reconsider whether some concepts centered on humans can be used in understanding animals.

1. The study on the cleaner wrasse made Alex Jordan .

A．doubt whether the mirror test is reliable

B．discover the secret about the fish’s sight

C．develop a better method to replace the mirror test

D．believe the cleaner wrasse is as smart as chimpanzees

3. What can we learn from the text?

A．It is relatively easy to test animals' consciousness.

B．Some concepts for humans can’t be applied to animals.

C．Animals rely on at least two senses to get to know themselves.

【推荐2】Scientists at University College London have discovered sets of regulatory genes, which are responsible for maintaining healthy hearing. The finding, made in fruit flies, could lead to treatments for age-related hearing loss (ARHL) in humans.

Globally, one-third of people aged over 65 experience hearing loss, and while there are thought to be more than 150 genes that may affect hearing loss, there is no unified (统一的) view on how to use these to develop hearing loss treatments.

In the study, published in Scientific Reports, researchers at the UCL Ear Institute assessed the hearing ability of the common fruit fly across its life span (around 70 days) to see if their hearing declines with age.

A fruit fly’s ears share many molecular (分子的) similarities with the ears of humans, making it an ideal tool for the study of human hearing loss.

Researchers found that the antennal ears of fruit flies also display ARHL with nearly all sensitive hearing measures starting to decline after 50 days of age. This made the researchers want to know if there were any “age-variable” genes in the flies’ inner ears which have kept the ears healthy for 50 days of their lives.

After closer examination, researchers identified a new set of regulatory genes—homeostasis genes. These genes are often responsible for picking up sound and the overall sensitivity of the ear. Using this information, scientists were then able to genetically modify (修改) the genes and prevent the flies from getting ARHL.

Professor Joerg Albert, lead author of the study, said: “While many studies have been conducted into the hearing function of fruit flies, ours is the first to look at the mechanistic and molecular detail of their auditory (听觉的) life course. The fact that these genes are conserved in humans will also help to focus future clinical research in humans and thereby accelerate the discovery of new gene-therapeutic strategies. ”

The year of 2017 marked the 100th birthday of the honoring Chinese-American architect Ieoh Ming Pei.

From museums to business headquarters, Pei had designed many notable buildings around the world throughout his long professional career. According to the organizers of ''Rethinking Pei: A Centenary Symposium (百年纪念座谈会)” held that year, Pei remained one of the most celebrated architects of the 20th and early 21st centuries.

The Hong Kong Bank of China Tower is one of his most famous works in Asia. As the bank itself also celebrated its centenary in 2017, it’s worth examining the building's historical and architectural background to gain a deeper understanding of the architect who changed Hong Kong's skyline forever.

The Bank of China Tower (BOC Tower) was completed in 1989, a year which the "New York Times" called ,•the year of I.M. Pei.” For it was in this same year that Pei also completed the glass pyramid of the Louvre Museum in Paris, the Meyerson Symphony Center in Dallas, the Creative Artist Agency Headquarters in Los Angeles, and other marvellous architectures all around the world.

Pei was commissioned (委托)in 1982 by the Beijing-based Bank of China to design itsheadquarters in Hong Kong, but construction did not start until 1985.

There were many reasons for the delay. One of the biggest was the huge challenges posed by the location. The land parcel had been the address of a Victorian building which served as a prison during Japanese occupation of Hong Kong between 1941 and 1945. This terrible heritage might be one of the reasons why it was dismantled in 1982.

For I.M. Pei, the challenge of the site was not its past, but its present: the relatively small land parcel was surrounded on three sides by elevated roadways serving high-speed heavy traffic, meaning there was no possible public pedestrian access. Then there was its awkward trapezoidal (梯形)shape and the fact that the site also had a deep north-south height difference.

Another challenge was the unavoidable comparison of the BOC Tower to the neighboring Hong Kong and Shanghai Bank Headquarters(HSBC), which was also under construction. A spectacular building generously funded, its architect Norman Foster was simply told to create “the best bank building in the world.” At that time it was also the world's most expensive building, costing $668 million. The Bank of China Tower's budget was approximately one fifth of the budget allowed by HSBC.

The Hong Kong government had promised HSBC that no tall buildings would ever be built in front of its headquarters. Besides, in between the site of the Bank of China and the harbor, there were already a few buildings over 70 meters tall blocking views.

Recognizing that going tall was the only way to create a landmark at this site with his budget, Pei came up with an architectural tower design that was simple, expressive, innovative, and upon its completion, the tallest building outside of America and the fourth tallest in the world.

After the Bank of China officially moved into the tower in 1991, noted architect and critic Peter Blake visited the building and declared it to be "probably the most innovative skyscraper structure built anywhere to date."

Now 30 years after the building^’s construction, the Bank of China Tower continues to offer valuable lessons of architectural and structural creativity under the most demanding conditions. Most importantly, the tower has become one of the most important cultural icons for the city of Hong Kong.

【推荐1】Scientists have created a scent(气味)-delivery system that releases a pleasant fragrance when you sweat. Apply it to your skin, and the more you sweat, the better you’ll smell. That’s because the perfume only gets released upon contact with moisture(湿气).

Chemists from Harvard University combined two compounds(化合物) to create their new system. One chemical is alcohol-based. This is the nice-smelling perfume. The other chemical is an ionic liquid(离子性液体), which is a type of salt that is liquid at room temperature. Ionic liquids are made of ions---molecules that have lost or gained one or more electrons. If the molecule loses electrons, it will have a positive charge. If it gains electrons, it gets a negative charge. Ionic liquids contain the same number of positive and negative ions, which makes them neutral(中性的), with no overall electric charge. In general, ionic liquids have no smell.

When the perfume and ionic liquid are mixed together, a chemical reaction occurs. This bonds the molecules to each other. The reaction also temporarily inactivates(使不活跃) the perfume’s molecules. So when applied to the skin, the new perfume has no scent in the beginning. But adding water or sweat breaks the bond between the molecules. That releases the scent into the air.

“The rate of the release of the fragrance depends on how much you sweat, in other words, how much water is available,” explains chemist Nimal Gunaratne from Harvard University, who led the research. “Sweat is like the command to let the fragrance go.”

Christian Quellet is a chemist who has worked in the perfume industry for a long time. He is now an independent consultant based in Switzerland. “Gunaratne’s perfume opens the door to new developments and applications of fragrance controlled-release systems,” he says. Controlled-release systems allow small quantities of some compounds that they hold to enter the environment slowly.

The system also traps some chemicals in sweat that are responsible for the bad sweat smell. These compounds are called thiols (硫醇). Just as water does, thiols break apart the bond that ties the perfume to the ionic liquid. When this happens, the thiols attach to the ionic liquid and their bad scent is inactivated as the perfume had been. This means the water in sweat and its thiols are both able to release the fragrance from the newly developed perfume.

1. Which of the following makes the scent delivery system special?

A．When it releases scent can be well controlled.

B．No perfume is required in the system.

C．The scent can last for a long time.

D．Sweat can help release the scent.

A．the perfume comes into contact with the skin

B．the perfume and ionic liquid contact each other

3. What Nimal Gunaratne says in Paragraph 4 suggests that with this scent-delivery system _____.

A．the more you sweat, the better you will smell

B．the perfume can’t always cover the bad smell.

C．how much water is available doesn’t matter much

D．how you smell depends on how much perfume you use

4. What is Christian Quellet’s attitude towards Gunaratne’s new perfume?

A．Indifferent.

B．Favorable.

【推荐2】NASA is studying ways to build human habitations on the Red Planet. In 2016, SpaceX publicly announced a plan to begin building settlements Mars. This mission (任务)could put people on Mars by 2026. This is why astrobiology students at Villanova began their Mars Gardens project, investigating which plants and vegetables can grow in iron oxide-rich Martian soil simulant (模拟物).

A few billion years ago, Mars had a better environment, complete with oceans, a mild climate and quite possibly —life. It has since lost most of its atmosphere and water and there's currently no water on its surface. Water (or ice) is present beneath the surface, however, as well as in the planet's icy polar areas. The tough conditions on Mars make it necessary for all plants to be grown in heated, pressurized greenhouses with significant compensations (补充)made for atmosphere, wetness and water.

In their greenhouse experiments, the Villanova students took measures to create an environment that's both plant-friendly and similar to what would be found in greenhouses on Mars. They made sure, for example that plants received roughly the same amount of sunlight as they would on Mars. The students found that their success rates improve by using multiwavelength LEDs and adding potting soil or earthworm feces.

The students were able to get certain vegetables from consideration. For example, the low light on Mars does not lend itself well to growing plants that require full sun, which include favorites like tomatoes, beans, corn or many root plants. Carrots also don't make the cut. Potatoes largely don't thrive in the simulant soil and low light conditions, but sweet potatoes do a little better.

The students found that dandelions (蒲公英)would grow well on Mars and have significant benefits: they grow quickly, every part of the plant is eatable, and they have high nutritional value. Other thriving plants include microgreens, lettuce, peas and so on.

1. What do the students at Villanova intend to do with their project?

A．Design space crafts for the Mars mission.

B．Choose possible plants to be grown on Mars.

C．Study reasons for environmental changes on Mars.

D．Test models of human settlements to be set up on Mars.

2. What is the environment on Mars like?

A．The air pressure is low.	B．The temperature is high.
C．The soil is plant-friendly,	D．The sunlight is abundant.

3. What does the underlined word “thrive” in Paragraph 4 mean?

A．Have high nutrition.	B．Require full sun.
C．Grow well.	D．Adjust to the conditions.

【推荐3】Australian experts have expressed concerns that too many millennials(千禧一代）are hoping to use their social media accounts to build their careers.

Their concerns follow the sudden rise in "insta-celebrities" who make money by posting sponsored photos online. For the lucky few who are not only talented photographers but also good-looking and business-savvy(有商业头脑的)，making money off social media isn't impossible.

Instagram is flooded with social media professionals paid to promote products and services. However, social scientist Dr Lauren Rosewarne, from the University of Melbourne, says that in reality, there are far fewer people making money off the platforms than one may think.

She said many young Australians were getting sucked in by the appeal of making money on platforms like Instagram, describing it as "totally unrealistic" and extremely difficult to do.

"Young people are hoping to be famous in numbers that were simply not there 20 years ago," Rosewarne told the Australian Broadcasting Corporation(ABC) on Saturday. "There are some people who can make fortunes out of monetizing(使具有货币性质)their Instagram posts, but that is not the norm."

She said it was up to parents and schools to discourage students from seeking Insta-fame, as many believe it is a possible career choice. "There's the warning for parents; this is not a normal or even common occurrence that you can monetize your Instagram account."

Meanwhile Toni Eager from Australian National University said social problems could arise from spending too much time with social media.

"Where do the insta-celebrities go ... to separate the life people see on Instagram from their actual normal life?" Eager said. "All of a sudden, people own your private life."

1. Why is there a sudden rise in "insta-celebrities"?

A．Many young people want to be photographers.

B．Many people see it as a shortcut to making money.

D．Instagram offers young people more career choices.

2. The underlined phrase "getting sucked in" in Paragraph 4 probably means"______".

A．benefiting from something

B．becoming involved in something

C．taking advantage of something

D．being satisfied with something

3. What message does the author convey by quoting Dr Lauren Rosewarne?

A．Young people today are more business-savvy than ever.

B．Young people are becoming less interested in Internet fame.

C．Instagram is not a good platform to promote new products.

D．It's a bad idea for young people to try earning money on Instagram.

4. What problem does Toni Eager think overuse of social media could cause?

A．An over-reliance on Instagram.
