24、 Few of us have heard of Nils Bohlin, but whenever we take a car journey, his invention makes us safer. Found in almost every modem car, the three-point seat belt reduces our chances of death or injury (伤害) by at least 50%. While feeling thankful to this engineer from Volvo, you may also wonder how he came up with such a great idea.
Having worked as a plane designer before, Nils knew clearly that the pilots were willing to put on anything to keep them safe in an accident, but to his surprise, most people in the cars just didn't want to be uncomfortable for even a minute. To improve the safety for people in the cars, he decided to find a perfect system which should be simple, effective and convenient. In the end, he invented the three-point seat belt, which has been considered as one of the greatest inventions in history.
Seat belts prevent people in the cars from serious injury in five ways.
Keep people inside. People who are thrown out from a car are four times more likely to be killed than those who stay inside.
Protect the strongest parts of the body. Seat belts are designed to fix your body at its strongest parts. For an older child and adult, these parts are the hips (臀部) and shoulders.
Spread out the force in an accident. Seat belts spread the force of the accident over a wide area of the body. By putting less stress on one area, they can help you avoid serious injury. Seat belts also help keep your upper body away from the hard parts of the car if you stop suddenly or are hit by another car.
Help the body to slow down. A quick speed causes injury. With the help of the seat belts, your body can have more time to slow down in an accident.
Protect your brain and spinal cord (脊柱). Seat belts are designed to protect these two key areas of the human body. Head and spinal cord injuries may be hard to see immediately, but they can cause death. Therefore, it's of great importance to protect these parts.
It takes only few seconds to buckle up (系好安全带) once you get in the car, but this simple action could save your life. Why wouldn't you?
【1】Three-point seat belts reduce chances of death or injury by at least __________.
A.10% B.30% C.40% D.50%
【2】From the passage we can learn _________.
A.hips and shoulders aren't the older children and adults' strongest parts.
B.seat belts can keep your knees and feet away from the hard parts of the car.
C.the body has more time to slow down in an accident with the help of seat belts.
D.head and spinal cord injuries might be easy to see immediately and cause death.
【3】This passage is mainly about _____________.
A.how seat belts are made B.how seat belts are used
C.how seat belts save lives D.how seat belts develop better

26、Chinese astronauts gave a science lesson to millions of students on Dec 9, 2021. They did so from 400 kilometers above Earth, from the Tiangong space station. The three, Zhai Zhigang, Wang Yaping and Ye Guangfu, showed life in space and did experiments in gravity.
“It was the first lesson of the Tangong class, China’s first in space.” noted China Daily. “Its goal is to make more people know space science.”
“The lab of the space station has many conditions that the Earth lab does not have, such as the environment of weightlessness and radiation.” Wen Xin, a professor at University, told Xinhua. He said that important jobs for astronauts in the space station include research of cell growth and plant life.
In the lesson, Ye did experiments that had to do with cell growth in a weightless environment. He compared the growth and shape of cells in artificial gravity and zero gravity to study their changing rules in space. This was not the first time that China has tried to grow plants in space. As early as 2016, Chinese scientists grew rice on the Tiangong Ⅱ space lab to study how plants grow without an Earth-like environment.
Another experiment in the space lesson was shown by Wang Yaping. She showed how a paper flower “bloomed” on the surface of water in Tiangong space station. She explained that the surface tension of water becomes stronger in space due to zero gravity. Surface tension is like a “skin” of water. One of the examples of surface tension on Earth is that some insects can walk on water. Most of the time, gravity is too strong and it breaks the “skin”. But with zero gravity in space, some insects can use surface tension to “stand” instead of falling through water. Surface tension plays a key role in product development. Researchers are measuring surface tension to improve the quality of their products. Detergent effect can be improved with even lower amounts. Surface tension also has influence in medicine development.
Although the astronauts are thousands of miles away, their research really influence our life. Shi Yi, a teacher, told China Daily that the space lesson was “an eye-opening experience that would attract more students to study science”.
【1】What do we know about the science lesson?
A.Its goal is to study the cell growth in space.
B.It focused on the use of zero gravity in space.
C.It only showed experiments in artificial gravity.
D.It was the first lesson from China’s space station.
【2】Ye’s experiment about is mainly about?
A.Ways to study the rules of cell growth.
B.How to better develop space-grown plants.
C.How cells grow in a weightless environment.
D.Differences between artificial gravity and zero gravity.
【3】What can we learn about from water surface tension from the passage?
A.It always gets stronger when increases.
B.It makes insects fall through water In space.
C.It helps plants to grow better in space.
D.It can help to make better detergents.
【4】What’s the best for the passage?
A.Tiangong space station
B.Special teachers from space
C.A science lesson in space
D.A study of weightlessness
27、 Even the closest star to us, Proxima Centauri, is very far away.
Scientists would love to get a closer look at this star and its planets. But the fastest spaceship ever built would take nearly 75,000 years to get there. That's just too long!
Scientists have come up with a plan-send a group of very tiny spaceships. Why tiny? The smaller something is, the easier it is to make it go fast. They're hoping a group of stamp-sized ships(Star Chips)could travel fast enough to reach Proxima Centauri in just 20 years. There they could take pictures and collect information. If there is any life there, the Star Chips might be able to find it-and say hello from Earth.
Each Star Chip will carry a tiny camera, thrusters, and sensors. It will ride a sail about the size of a picnic table. The plan is to send many, in case some don't make it.
Scientists hope that their tiny Star Chips will be able to reach a speed of 134 million miles(216 million km)an hour. First, the rocket will take the Star Chips to space. Once in space, they will open their shining sails. Then, people on Earth will shoot out lasers at the sails. All those lasers shot at the sails will push the Star Chips so fast that they will reach the moon in just two minutes.
The computer chip at the heart of each Star Chip is tiny like the ones in mobile phones. None of the other technologies has been built yet. The hardest part will be the lasers, which have to be extremely powerful. The team will also need to invent a light, strong, and very shiny material for the sails, and tiny cameras powerful enough to take pictures of planets. And they'll have to find a way to send those pictures back to Earth. There's a lot of work ahead. But if they succeed, the heart of a mobile phone may be the very first interstellar traveler.
【1】Scientists plan to invent the Star Chip mainly because it .
A.could send messages to other planets B.could take photos and collect information
C.could find life in other stars and planets D.could be small enough to travel much faster
【2】Powerful lasers will be shot at Star Chips to .
A.make sure Star Chips won't be hit in space B.send Star Chips to space from Earth safely
C.open the strong and shining sails of Star Chips D.give Star Chips enough energy to travel in space
【3】What technologies about Star Chips are still waiting to be built?
①The way to send pictures back to Earth.
②The strong and shiny material for the sails.
③The tiny cameras able to take photos of planets.
④The chip as small as the ones in mobile phones.
A.①②③ B.②③④
C.①②④ D.①③④
【4】What is the best title of the passage?
A.A Chip with Great Power B.A New Coming Spaceship
C.A Big Problem about Star Chips D.A Great Trip to Proxima Centauri

29、 Several years ago, when I was teaching at a middle school, a girl sent me a message. She found someone write a very ________ message on her locker. She made a picture of it and then sent it to me asking for ________.
