The Coolest Inventions
An Oceans Vacuum
There’s a collection of plastic trash in the middle of the Pacific Ocean. It’s bigger than Texas and growing. The way to clean it up now is to catch it with nets. That is both costly and slow. Instead, the Ocean Cleanup Project proposes a 62-mile-long floating barrier that would use natural currents to trap trash. If next year’s trials succeed, a full cleanup operation would aim to start in 2020. It could reduc e the trash by 42 % over 10 years.
Easy-On Shoes
In 2012, Matthew Walzer, a high school student with a disability, sent a note to Nike. “My dream is to go to college,” he wrote, “without having to worry about someone coming to tie my shoes every day.”
Nike assigned a design team to the challenge. This year, they came out with their solution: the FlyEase. The basketball shoe can be fastened with one hand. A pair of Nike FlyEase shoes sells for $ 130.
An Airport for Drones (无人机）
As Amazon, Google, and others get ready for drone delivery service, there is one big question: What kinds of home bases will their drones have? Rwanda, in Africa, may have the answer. There, workers will soon start work on three “drone ports”. The goals is to make it easier to transport food, medical supplies, electronics, and other goods through the hilly countryside. Construction is set to be completed in 2020.
21. What’s the advantage of the Oceans Vacuum?
A. It can tear plastic into pieces.

Throughout history scientists have risked their health and their lives in their search for the truth.
Sir Issac Newton, the seventeenth century scientist was very smart, but that didn't stop him from doing some pretty stupid things. In his laboratory in Cambridge, he often did the strangest experiments. Once, while testing how light passes through lenses (晶状体), he put a long needle into his eye, pushed it to the back, and then moved it around just to see what would happen. Luckily, there was no lasting bad effect. On another occasion, he stared at the sun, for as long as he could bear, to discover what effect this would have on his sight. To escape suffering permanent damage, he had to spend some days in a dark room before his eyes recovered.
In the 1750s, the Swedish chemist Karl Scheele, was the first person to find a way to produce phosphorus (磷) He, in fact, discovered eight more chemical elements, including Chlorine (氯), though he didn't get any place for them. He was a very clever scientist, but he had a strange habit of tasting a little of every substance he studied. This risky practice finally caught up with him. In 1786, he was found dead in his laboratory, surrounded by a large number of dangerous chemicals, any of which might have been responsible for his death.
Eugene Shoemaker was a respected geologist, he spent a large part of his life studying craters (陨石坑), and how they were formed, and later the research into the comments of the plane Jupiter. In 1997, he and his wife were in the Australian desert, where they went every year search for places where comets (彗星) might have hit the earth. While driving in the Tanam desert, one of the most open places in the world, another vehicle rushed into them, and Shoe maker died on the spot. Some of his ashes (骨灰) were sent to the moon by the Lunar Prospect or, a spacecraft, and he is the only person who has this honor.
24. What does the underlined word "permanent" in Paragraph 2 mean?
A. Lasting.
B. Slight.
C. Brief.
D. Ordinary.
25. What did Karl Scheele like doing when performing experiments?
A. Tasting chemicals.
B. Staying in the empty labs.
C. Experimenting in darkness.
D. Working together with others.
26. What special honor was Shoemaker given after his death?
A. He was buried in the Tanami desert.
B. One comet of Jupiter was named after him.
C. Some of his ashes were placed on the moon.
D. A spacecraft carrying him travelled around Jupiter.
27. The text is mainly about three great scientists' __________.
A. special honors
B. great achievements
C. suffering in their research
D. famous experiments
C
"We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度）and nutrient availability seem to have trumped the benefits of increased carbon dioxide" said researchers from the National University of Singapore.
45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures.
“ We do not yet know the mechanisms(机制）involved, or why some organism are getting smaller while others are unaffected,” the researchers said. “Until we understand more,we could be risking negative consequences that we can’t yet quantify. ’’
The change is big in cold-blooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行动物）smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growing.
Warm-blooded animals aren’t immune(免除）from the size change caused by climate change. Many birds are now smaller. Soay sheep are thinner. Red deer are weaken And polar bears are smaller, compared with historical records.
This is not the first time this h as happened in Earth’s history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change.
The speed of modern climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times climate change will be shown in the future.
28. What does the text mainly talk about______?
A. Why some species become smaller.
B. How climate changes in Earth’s history?
C. Climate change has many negative effects.
D. Species are becoming smaller as climate gets warmer.
29. The underlined word “trumped” m the first paragraph probably mean________.
A. strengthened
B. gained
C. equaled
D. beaten
30. Researchers from the National University of Singapore believe that________.
A. they have found the exact causes for creatures getting smaller.
B. all the animals on the earth have become smaller.
C. climate change has more negative effects on warm-blooded animals.
D. increase in energy use can lead to creatures getting smaller.
31. What does the author feel about the climate change?
A. Worried
B. Optimistic
C. Disappointed
D. Shameful
D
If y ou’re DIY-minded, you can build your own solar power system. In some cases, you can even build your own solar panels (太阳能电池板), although the amount that you can effectively DIY home solar depends on how much you want to power. Making your own solar panel is a time-consuming process and requires some electrical skills. However, it can also be very rewarding—learning to build your own panel is a great way to understand how solar electricity is generated (产生).
Before you can build your own solar panels, you first need to understand how solar cells generate electricity. Once you’ve bought individual solar cells (they can be purchased online), the basic process for building your own solar panel goes like this: Prepare the backing (底板) for your panel. Many DIY solar panel builders prefer to use a wooden board as the base for their solar cell. You’ll need to drill holes in the board so that the wires for each cell can pass through. Wire your solar cells together. This requires some experience with electrical work. Use a soldering iron (烙铁) to attach wire to the solar cells and then link each of the cells together. Attach cells to your backing. If possible, attach each solar cell to the backing individually. This makes it easier to replace a single cell in the event that becomes damaged or is not operating properly.
At this point you have a functional solar panel that can produce electricity when the sun shines. However, a solar panel by itself is not useful. If you are trying to generate electricity to power devices in your home, you need to pair your panel with an inverter (换流器) that will turn direct current (DC) power from the sun into the alternating current (AC) power used in most modem electronic devices.
32. What does the author think of building DIY solar panel in the first paragraph?
A. It is easy.
B. It is common.
C. It is worthwhile.
D. It is necessary.
33. What’s the first step of building your own solar panels?
A. Buy individual solar cells.
B. Drill holes in the wooden board.
C. Prepare the backing for your panel.
D. Master the advanced knowledge of management.
34. Why are solar cells connected to the wooden board separately?
A. To produce more power.
B. To substitute damaged cells easily.
C. To attach cells to the backing tightly.
D. To pass through the wooden board easily.
35. What can be inferred from the text?
A. People with electrical skills have advantages over those without in DIY solar panels.
B. A functional solar panel can give power to your home devices directly.
C. How to pair an inverter depends on how much you want to power.
D. A wooden board is a must for your own solar panels.

He was a very clever scientist, but he had a strange habit of tasting a little of every substance he studied. This risky practice finally caught up with him. In 1786, he was found dead in his laboratory, surrounded by a large number of dangerous chemicals, any of which might have been responsible for his death.
Eugene Shoemaker was a respected geologist, he spent a large part of his life studying craters (陨石坑), and how they were formed, and later the research into the comments of the plane Jupiter. In 1997, he and his wife were in the Australian desert, where they went every year search for places where comets (彗星) might have hit the earth. While driving in the Tanam desert, one of the most open places in the world, another vehicle rushed into them, and Shoe maker died on the spot. Some of his ashes (骨灰) were sent to the moon by the Lunar Prospect or, a spacecraft, and he is the only person who has this honor.
24. What does the underlined word "permanent" in Paragraph 2 mean?

C. Brief.
D. Ordinary.
25. What did Karl Scheele like doing when performing experiments?

D. Working together with others.
26. What special honor was Shoemaker given after his death?
A. He was buried in the Tanami desert.
B. One comet of Jupiter was named after him.
C. Some of his ashes were placed on the moon.
D. A spacecraft carrying him travelled around Jupiter.

"We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度）and nutrient availability seem to have trumped the benefits of increased carbon dioxide" said researchers from the National University of Singapore.
45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures.
“ We do not yet know the mechanisms(机制）involved, or why some organism are getting smaller while others are unaffected,” the researchers said. “Until we understand more, we could be risking negative consequences that we can’t yet quantify. ’’
The change is big in cold-blooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行动物）smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growing.
Warm-blooded animals aren’t immune(免除）from the size change caused by climate change. Many birds are now smaller. Soay sheep are thinner. Red deer are weaken And polar bears are smaller, compared with historical records.
This is not the first time this has happened in Earth’s history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change.
The speed of modern climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times climate change will be shown in the future.
28. What does the text mainly talk about______?
A. Why some species become smaller.
B. How climate changes in Earth’s history?
C. Climate change has many negative effects.
D. Species are becoming smaller as climate gets warmer.
29. The under lined word “trumped” m the first paragraph probably mean________.
A. strengthened
B. gained
C. equaled
D. beaten
30. Researchers from the National University of Singapore believe that________.
A. they have found the exact causes for creatures getting smaller.
B. all the animals on the earth have become smaller.
C. climate change has more negative effects on warm-blooded animals.
D. increase in energy use can lead to creatures getting smaller.
31. What does the author feel about the climate change?
A. Worried
B. Optimistic
C. Disappointed
D. Shameful
D
If you’re DIY-minded, you can build your own solar power system. In some cases, you can even build your own solar panels (太阳能电池板), although the amount that you can effectively DIY home solar depends on how much you want to power. Making your own solar panel is a time-consuming process and requires some electrical skills. However, it can also be very rewarding—learning to build your own panel is a great way to understand how solar electricity is generated (产生).
Before you can build your own solar panels, you first need to understand how solar cells generate electricity. Once you’ve bought individual solar cells (they can be purchased online), the basic process for building your own solar panel goes like this: Prepare the backing (底板) for your panel. Many DIY solar panel builders prefer to use a wooden board as the base for their solar cell. You’ll need to drill holes in the board so that the wires for each cell can pass through. Wire your solar cells together. This requires some experience with electrical work. Use a soldering iron (烙铁) to attach wire to the solar cells and then link each of the cells together. Attach cells to your backing. If possible, attach each solar cell to the backing individually. This makes it easier to replace a single cell in the event that becomes damaged or is not operating properly.
At this point you have a functional solar panel that can produce electricity when the sun shines. However, a solar panel by itself is not useful. If you are trying to generate electricity to power devices in your home, you need to pair your panel with an inverter (换流器) that will turn direct current (DC) power from the sun into the alternating current (AC) power used in most modem electronic devices.
32. What does the author think of building DIY solar panel in the first paragraph?
A. It is easy.
B. It is common.
C. It is worthwhile.
D. It is necessary.
33. What’s the first step of building your own solar panels?
A. Buy individual solar cells.
B. Drill holes in the wooden board.
C. Prepare the backing for your panel.
D. Master the advanced knowledge of management.
