3 . For your next out-of-this-world vacation, you now have the option of literally going out of this world—but it’ll cost you $ 40 million. Then again, can you really put a price tag on having the time of your life? According to a new report from Popular Mechanics, Russia is looking to build a luxury hotel in outer space. There you will wake up to a breathtaking blue planet—the earth! The hotel is expected to be stationed on the International Space Station (ISS).

While space tourism itself isn’t exactly a novel idea, the notion of building a hotel out there hasn’t been raised before. Really, other companies are still focused on the transportation part of the puzzle — after all, a trip to space is enough for most folks.

According to Popular Mechanics, the hotel will include a luxury orbital suite with big windows, personal hygiene (卫生) facilities, exercise equipment, and yes, WiFi. Because if you can’t share your experience on social media, did it really even happen?

Of course, the reasons behind the hotel aren’t just for fun and games. Apparently, space tourism might be able to help the Russians pay for another module to add to the international Space Station. Russian space contractor RKK Energia is currently building the first such module, which will give scientists a laboratory and power supply station from which to conduct tests.

If any of this is going to happen, however, Russia is going to have to hurry. With the ISS expected to be out of use in 2028, there’s little time to build the hotel and find wealthy tourists to actually buy a trip into outer space.

So if you’ve recently come into a fortune and are interested in investing in what could be the time of your life, ISS is calling your name.

1. What do we know about the hotel from the first paragraph?

A．It is quite affordable.

B．It will be built in Russia.

D．It costs $ 40 million to build.

2. What does the underlined phrase “the puzzle” in Paragraph 2 refer to?

B．Visitors are required to take exercise each day.

C．Space travel is not possible without the Internet.

D．Tourists tend to share traveling experiences online.

4. The hotel will be built to provide Russian scientists with

4 . What I learned watching dentist at work

I would like to be a dentist in the future.     1     The patient, tender dentist comforted me, a 7-year-old girl at the time, and persuaded me to stop crying and to accept my treatment.

    2     Recently, our teacher gave us the homework of experiencing a kind of job on the weekend. I chose without hesitation to live a day as a dentist at my friend’s older brother’s workplace.

I got to Dr Tan’s clinic at 7:45 am, 15 minutes before office hours began on Saturday. Dr Tan, who has been a dentist for five years, sat in his consulting room with a mask on his face and waited for his patients. I didn’t really understand his diagnoses or treatments, but I could see that Dr Tan was a responsible doctor. He explained conditions and therapies (治疗方案) to patients at length to remove their doubts. He paused operations to let patients rest if the treatment was taking too much time.     3     Dr Tan worked for almost the whole morning without a break. He only made a phone call to his wife to remind her to have an antenatal (产前) examination. Yes, he will be a father in five months, but he still cannot keep his wife company at the weekend.     4       They try to ease others’ pain anytime and anywhere, despite the cost to their own time and life.

As the last patient said goodbye to Dr Tan in the afternoon, my visit came to an end. I now feel that I understand more about doctors.     5    

A．My dream has finally come true.

B．They are the heroes I admire most.

C．Doctors are ordinary people, yet they are also angels.

D．It helps me to reduce stress, find friends and learn new skills.

E．I thought it was a dream that was almost impossible to fulfill

F．That’s all because of a dentist I came across during my childhood.

G．He also gave a doctor’s advice to his patients carefully before they went out the door.

5 . Artificial intelligence （Al） could soon help screen for Alzheimer's （阿尔茨海默症）disease by analyzing writing. A team from IBM and Pfizer says it has trained Al models to spot early signs of the illness by looking at language patterns in word usage.

Other researchers have already trained various models to look for signs of cognitive impairments （认知损伤）by using different types of data, such as brain scans and clinical test results. But the latest work stands out because it used historical information from the Framingham Heart Study, which has been tracking the health of more than 14,000 people from three generations since 1948. If the new models' ability to pick up trends in such data holds up in forward-looking studies of bigger and more diverse populations, researchers say they could predict the development of Alzheimer's disease a number of years before symptoms become severe enough for typical diagnostic methods to pick up. And such a screening tool would not require invasive （入侵性的）tests or scans.

Researchers praise the study as a solid contribution to the field that might draw more attention and resources to Al detection of Alzheimer's disease. It's one of the very few works that analyze the big-scale, real-life data that was collected over a very long period of time.

The new models might have been more accurate if it could have contained handwriting. This ability could provide additional clues. Using Al speech analysis to diagnose Alzheimer's disease is a growing area of research, and other systems have focused on detecting changes in audio samples. These contain clues such as speech pauses, which are not found in writing.

Whether written or spoken, language samples offer a relatively noninvasive source of information for monitoring peoples, cognitive health, compared with brain scans and other laboratory tests. Collecting such language data could be done cheaply and remotely—though doing so would still require strict informed permission and private information safeguards for the individuals creating the samples. This is especially true because some people may not want to even know how likely they are to develop Alzheimer's disease.

1. How can Al help in spotting signs of Alzheimer's disease?

A．By scanning the person's brain.

B．By studying the person's various data.

C．By analyzing the person's word usage.

D．By testing the person's writing articles.

2. What's special about the Al models from IBM?

A．They are based on historical data.

B．They detect early signs precisely.

C．They are applied to a wider population.

D．They make follow-up studies unnecessary.

3. What might be a concern about the Al models for tested people?

A．Sample analysis.	B．Data analysis.
C．Screening results.	D．Privacy protection.

4. What can be a suitable title for the text?

A．Al——a way to fight Alzheimer’s	B．AI——a tool to detect Alzheimer's
C．Al — a trend in treating diseases	D．Al — a method for collecting data

6 . World Environment Day is celebrated annually on June 5th and was created to inspire people around the globe to take an active part in environmental protection and learn more about ways we can help to guarantee the future of our planet is safe.

The very first World Environment Day took place in 1974, established by the United Nations General Assembly on the first day of the Stockholm Conference on the Human Environment that took place in 1972.

Each year the United Nations pick a theme and a host city where anyone who is concerned about the environment can talk about environmental topics with others, followed by different kinds of exhibits to promote environmental awareness. Environmentalists, academics and scientists come together to bring new ideas on the table concerning the environment.

The 2018 World Environment Day is hosted by India, and the theme is Beat Plastic Pollution. It urges people to explore and choose supportable alternatives like paper or cloth bags to reduce the production and use of   disposable plastic, which makes up 10% of all of the waste. Even though the United Nations pick a specific host city every year, people around the world still celebrate World Environment Day in their hometowns with parades(游行), concerts, cleaning up and tree planting and all kinds of green actions to work towards having a beautiful planet and battling pollution.

World Environment Day is not a public holiday, so you won't be getting the day off work or school, but if you want to celebrate, why not bring it to the attention of your parents, friends, colleagues or classmates? World Environment Day is all about working together to take action for the planet, so try to get everyone you know interested in helping do something. Things as small as making sure people have a way to recycle can make a difference. You could also try beautifying your neighborhood by planting gardens, learn about green foods, raise money for a local wildlife conservation group of simply learn about the effects of different products on the earth.

1. Why is World Environment Day set up?

9 . A new course on world heritage, and its conservation offers a good opportunity for the young people to learn about the heritage(遗产) of humanity and gain a sense of responsibility to help protect the planet we live on.

According to a world heritage education programme jointly launched by the United Nations Educational, Scientific and Cultural Organization(UNESCO) and China’s Ministry of Education, the course will first be offered at several schools in Beijing before being included as a mandatory course(必修课) for high school students nationwide.

The new course covers photos slide shows and documentaries on the magnificence of the world heritage sites. The class aims to tell children what world heritage is and why and how it should be protected. A total of 171 nations, including China, have signed the Convention Concerning the Protection of World Cultural and Natural Heritage Listed are 754 sites all over the world, of which 29 are in China—the third most after Spain and Italy. Currently, protection of the country’s cultural and natural resources leaves much to be desired. Education is undoubtedly the best way to cultivate people’s sense for protecting cultural and natural resources.

The introduction of such a programme in Chinese classrooms will certainly help our young people realize the significance of common heritage, learning about world heritage sites, the history and traditions of different cultures, ecology, and the importance of protecting biological and cultural diversity.

More importantly, it will help cultivate a sense of responsibility in the minds of young participants. This is critical in protecting these cultural and natural legacies, as well as our living environment and the limited resources for sustainable development.

10 . The Nobel Prize is considered one of the most recognizable and admirable awards possible, honoring people of the world for their outstanding achievements in different fields.

Alfred Nobel was born in 1833 to a family of engineers in Stockholm, Sweden. Nobel as a young man studied with Nikolai Zinin, a well-known chemist. In 1850, he met Ascanio Sobrero, the inventor of nitroglycerin (炸药) in Paris. Interested in its unpredictable nature of exploding under pressure or heat, Nobel started to find a way to control it and make a usable explosive(炸药). In 1857 he applied for his first patent (专利), an English patent for a gas meter. After years of efforts, in 1867, at the age of 34, Nobel invented dynamite(炸药), which is much easier and safer to control than nitroglycerin. Dynamite was an immediate business success and it was patented in the US and the UK and was widely used in mining.

During his lifetime, Nobel invented and patented various explosives. He built up his wealth from his 355 inventions, from which dynamite was the most important.

When Alfred’s brother Ludwig died in 1888, a French newspaper mistakenly published Alfred’s obituary (讣告). Reading his own obituary, Nobel was disappointed to find out his public image(形象). The newspaper strongly blamed(责备) Nobel for inventing dynamite, giving him the nickname of “the merchant of death” and saying “Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday.”

To Alfred, this obituary was a warning. He spent his lifetime alone inventing things and was deeply concerned with how he would be remembered. This unfortunate event inspired him to make changes in his will(遗嘱), so as to improve his public image, and to be remembered for a good cause.

In 1895, one year before his death, Nobel made the last will, saying clearly that his wealth would be used to create a series of prizes for those who have made great contributions to mankind in physics, chemistry, physiology or medicine, literature, and peace. To widespread astonishment, Dr. Alfred Nobel gave away 94% of his total wealth to found the five Nobel Prizes.

1. According to paragraph 2, what led to Nobel’s outstanding achievements?

A．The valuable help from his family.

B．The strong desire to make money.

C．His lifetime dream of achieving success.

D．His great curiosity and devotion to science.

2. What was Alfred Nobel’s attitude towards the newspaper’s obituary?

A．Upset.	B．Supportive
C．Optimistic	D．Satisfied

3. Why did Nobel give away most of his wealth to set up the Nobel Foundation?

A．To publish his findings of scientific research.

B．To improve his public image.

C．To be remembered as the “Merchant of Death”.

D．To prove the importance of his inventions.
