Useful inventions
Inventions change how we live, work, play and think about what’s possible. Every year, TIME magazine lists (列出) the 100 best inventions based on their creativity (创造性) and impact (影响) on our lives. What did the magazine choose this year? Let’s take a look.
Easier to readReading can be a big challenge for tens of millions of people. They may have poor vision (视力) or reading difficulties. But OrCam Read can help them! It’s the first of its kind reading pen with a smart camera and an AI system. After scanning (扫描) a page of text with the click of a button (点击按钮), it can read the text aloud to the user. You don’t need to connect (连接) it to the Internet. You can use it offline at home, work, school, or eve in stores when you need to read a price tag (标签).
Sweet ideaHoney is produced by bees. But today’s beekeeping business (养蜂业) is not good for these hard-working insects. Bee farmers may kill them after harvesting (收获) honey because it’s cheaper than feeding the bees through the winter. To save bees, US company MeliBio has found a way to make the world’s first bee-free honey. They used synthetic biology (合成生物学) to create honey directly from plants. This kind of honey tastes just like the real one, and it is healthy, too.
Keep you calmWhen you feel angry or unhappy, what do you do about it? Scientists say you can try to calm others. This can help you calm down. That’s why Purrble was invented. This furry (毛茸茸的), bear-like toy has 9 sensors (感应器). It has a quick “heartbeat (心跳)” and can respond to your touch.
As you hold and pet it, its heartbeat slows. And it purrs (发出咕噜声) like a cat. It sounds like it really enjoys your touch! Through petting Purrble, you will become more aware of your own feelings and learn how to feel calm yourself.

Hushme is a high-tech mark(口罩) that can block the sound of the wearer’s voice so that people nearby can’t hear what is being said. It connects to your phone with Bluetooth and comes with a pair of earphones. When you get a private call, all you have to do is to put the mask on and it will do the rest.
The Hushme mask, which has different kinds of colors, can be worn around the neck, and in front of your mouth. It’s not yet clear how comfortable speaking with this Bane-like mask over your mouth really is, or how well it works. We know so far is that it makes you look strange.
The sound choices for covering your voice currently include wind, ocean, rain, birds, monkey, squirrel(松鼠), R2D2, laughing Minion6 and Darth Vader breath. And new ones could be added in the future.
You could also always use Hushme to protect your ears from loud noise from the co-workers at the office. Just put this small product over their mouths and you can get on with your work.
Hushme was on show at the beginning of this year. Its makers plan to start selling it by the end of the year. It will cost around $200.

Microchips bring good news to patients with long-term( 长期的) illnesses, for example, Osteoporosis( 骨质疏松症). People with Osteoporosis have to get daily injections( 注射) of medicine. One type of treatment requires injections for two years. Many patients stop taking the medicine because of the pain and stress of the infections. However, microchips can deal with it. Doctors will program the device before putting it under the skin, and the device has the ability to release(释放) a dose (剂量) at a given time, every single day. One microchip can hold a full year’s worth of medicine.
Microchips may one day free (使…… 摆脱)people from having to remember to take their medicine, or get injections. The device may also be useful in treating other long-term diseases, including heart disease, cancer and even AIDS.

【推荐3】You probably have the childhood memories of watching the Slinky walk its way down the stairs. The helical (螺旋形的) spring toy was invented by Richard James in 1943. While James was testing ways to keep equipment safe on the U. S. Navy Ships, one of the springs fell and began to “walk”. Seeing the spring can be marketed as a toy, he took the idea home to his wife Betty, who named it the Slinky after looking through a dictionary.
![](https://img.xkw.com/dksih/QBM/2023/2/21/3179626711490560/3180942289682432/STEM/9c285f4b341e4c549d4d3a7303727b89.png?resizew=165)
In 1945, James perfected the design of the Slinky, which was about 24 metres of wire shaped into a helical five centimetre-tall spring. The new product was a hit: By the end of the 1945 holiday season 22, 000 Slinkys had been sold. It went on to become the must-have toy of the mid to late 20th century. Many reasons have been given for the Slinky’s popularity: “It’s cheap.” “It teaches kids physics.” “Children love simple things.” and so on.
As a child, making a Slinky step perfectly from the top of the stairs to the bottom is exciting. The Slinky gets its “walking” ability from two properties: wave motions and Newton’s laws. Sitting at the top of the stairs, the Slinky remains-unchanged, like all objects that are not being moved by other forces. When the Slinky is knocked off the first step, gravity acts upon its coil. Then energy is transferred (传递) from coil to coil until it arrives at the end of the slinky, which makes it stretch to reach the next step down, reform itself, then stretch again to reach the next step, and so on.

Reading people’s minds seems to be a superpower that only happens in movies. But scientists have now made it possible to read people’s mind!
Researchers at the University of California, San Francisco developed a new instrument. It can turn brainwaves into words on a screen in front of the user. In the study, they tested it with a paralyzed (瘫痪的) man. “To our knowledge, it’s the first time to directly decode (解码) full words from the brain of someone who is paralyzed and cannot speak,” said Edward Chang, the senior author of the study. Each year, thousands of people lose the ability to speak because of accidents or illnesses. With up to 93 percent being correct the new instrument shows “strong promise” to let these people fully communicate in the future.
One problem with such mind-reading machines, however, is that they have to put electrodes (电极) into people’s brains. It’s inconvenient and has health risks. But scientists from the University of Texas, US, have taken steps to change this. They tried to read people’s thoughts without even touching their heads, reported Live Science.
The new brain scanning (扫描) method is called FMRI, it’s a safer way of “reading” brain activity. Since active brain cells (细胞) are easier to be read. By tracking them, scientists can read brain activity.
The team asked people in the test to listen to 16 hours of radio shows while scanning their brains. Then they used a computer algorithm (算法) to create a story based on the FMRI recording. It matched the radio shows pretty well.
In other tests, the algorithm could basically explain the story of a silent movie that the people in the test watched. It could even retell a story that the people imagined in their heads. Although it’s not a word-for-word translation, the method-FMRI shows many possibilities.
1. From Paragraph 1 and Paragraph 2, we know that the new instrument can ________.A.teach paralyzed men to speak | B.help to read people’s minds |
C.make people become stronger | D.change people’s way to think |

Do you know that there’s a possibility that you may live forever? You will have computers which are 1,000 times more intelligent than Albert Einstein, one of the smartest scientists ever in the world? Yes! All these may happen in 20 years or more. In the next 20 or 30 years, the world will change much faster than ever before because the technology change will be simply breath-taking.
Computers will acquire human personalities, as well as the ability to understand words and their meanings when you speak to them. Tomorrow’s computer will be so developed that it can have a face-to-face chat with you like an old friend. In fact, you don’t even have to speak to it. Just like a friend, the computer will also have the ability to understand your thoughts.
However, will computers take over the world? Probably not, for people will also acquire-superhuman abilities. They may never die. “Unless a person is unlucky enough to die early from an accident or a disease, he has a good chance of not dying at all. Genetics will make this possible.” says Pearson, a British futurologist as well as a trained physicist.
Recently there have been many reports about discovering the code of the human genome, which determines many aspects of heredity. This finding will make it possible to repair damage caused by age and disease, keeping people young forever. Besides, if people suddenly die, it would be possible to recreate them with the help of the genetics.
So we have the reason to believe, with the development of genetic engineering and computer science technology, human beings will have superhuman abilities and the possibility of being young and alive forever. While at the same time, computers will be much more intelligent than we can imagine. Then who will control the world?

Airships can fly because they are lighter than air, like balloons. But they also have engines, so they can fly long distances. In the 1920s and 1930s, airships flew with passengers in them. They could fly from Europe to the US in two days. That was much faster than traveling by ship. There were even restaurants and bedrooms in the biggest airships, which could carry up to 100 passengers.
However, the safety of airships during that time was surely a big problem. It was reported that many of airships crashed. In 1937, a famous airship called the Hindenburg crashed near New York and thirty-six people died. After that, passenger airships stopped flying. Planes became the most important kind of air transportation because they were faster and safer.
Now a number of companies around the world are making airships again. They are much safer than the airships of the 1920s and 1930s, but they are not for passengers. Instead, they carry cargo.
Why use airships instead of planes? There are four main reasons:
●They don’t need airports. They can land in places where planes can’t.
●They can carry much more cargo than planes can.
●They use much less fuel than planes, so they are better for the environment.
●They can stay in the air for a long time, so they are good for scientific work.
Today most cargo still travels on planes, ships, trains and trucks. But in the future, much more cargo could travel by airship because it’s cheaper and better for the environment. Maybe there will be airships for passengers again too.

Cinyee Chiu, an artist from Taiwan, is always happy to try something new. Her amazing works won lots of prizes. Among them, the “24 Solar Terms(节气)” is the most popular.
Ancient Chinese divided a year into 24 parts according to the changes of the weather. It’s the 24 solar terms. But not everyone knows them well. Cinyee Chiu put the 24 solar terms in pictures to help people understand them better.
Cinyee turned each solar term into an animal. But these animals are not just animals. You can also find seasonal fruits, vegetables or beautiful flowers on them.
When spring comes, water gets warm and fish start to swim around. So Cinyee chose fish as a symbol of Start of Spring. Also, she drew spring vegetables, Chinese chives on the back of the fish.
White Dew(露珠)falls on about September 8. It shows the beginning of the cool autumn. There are colorful leaves and cooler nights at the time of year. As the temperature falls, white dew is often seen on the grass and trees at night. For White Dew, Cinyee chose a raccoon—a small animal with thick hair. She drew white spots(小圆点)on the raccoon to show dew. And she used the dragon fruit to show the rich colors in autumn.
The young artist really gave the ancient Chinese culture a new look.
1. The writer gave three examples to show Cinyee’s “24 Solar Terms(节气)”.2. From Paragraph 5, we know that Cinyee used white spots to show dew.
3. The writer mainly wants to talk about how Cinyee showed the 24 solar terms.
4. According to the passage, all of the following pictures are from Cinyee’s “24 Solar Terms(节气)”.
And now in order to fight against this disaster, a radio station in Senegal, West Africa, is offering listeners 5 kilograms of rice if they can catch and kill 50 kilograms of locusts. “We think this idea will get more people to take part in the fight against the locusts,” said Abdoulaye Ba, from Sud-Fm, a radio station in one of Senegal’s worst affected area.
This is West Africa’s biggest locust disaster in 15 years. Now it is moving east and it leads to the loss of crops. When they move, they have babies, so their number is getting bigger. and will soon threaten (威胁) Sudan in the northeast of Africa. Some say it may reach Asia.
Experts say many people in the areas will go hungry because of this disaster. What’s worse, governments in the areas don’t have enough things to fight the locusts.
Although leaders of 12 countries have agreed on a plan, it is not enough. ‘We are now treating 6,000 hectares (公顷) per day with pesticide (杀虫剂), but we need to treat 20,000 hectares per day in order to have any hope of controlling this disaster,’ said Mohamed Abdallahi Ould Babah, leader of locust control(控制) in Mauritania.
