Some 118,000 of these people can use neither their arms nor their legs. For these people, using a computer is a big
8、 difficulty. Some researchers have invented ways for such people to control a computer using brain waves or the movements （移动）of their eyes. But theyre riot easy for those who need them to use. After learning about the situation, Emma Mogus decided to take action.Emma, 17, is a 12th grader at White
9、Oaks Secondary School in Oakville, Canada. She has come up with an easier way for many such people to control a computer: using their tongue. She showed her invention at the Intel International Science and Engineering Fair recently. Created by Society for Science & the Public and supported by Intel,
10、 this years competition brought together more than 1,750 students from 75 countries.Emma built a prototype （模型）of her device using simple parts. The main part is a mouth guard, like those used by football players or other athletes. Emma made five holes in the mouth guard that a tongue could reach: t
11、wo on the left side, two on the right, and one in the front. She placed a pressure-sensitive switch （开关）in each hole. Four of the switches act like the up, down, left and right arrows on a computer keyboard. The fifth acts like the “click” button on a computer mouse. Together, all of these parts cos
12、t less than $10. Emma, s prototype sends a signal to a computer through a wire. But future ones could be designed to send those signals wirelessly （无线地），she notes.In tests, volunteers were able to quickly learn how to use Emmas device. After just some time, they were using the computer more quickly
13、and typing more words per minute than when they started. Emma thinks that her invention could be useful for far more people than just those with spinal-cord injuries. People with other conditions might use the device, too.5. Emma Mogus decided to take action to _.A. try to treat people with spinal-c
14、ord injuriesB. help people control a computer using brain wavesC. control a computer through the movements of eyesD. help people with spinal-cord injuries use a computer easily6. What are the holes in the mouth guard used for?A. Helping users breathe easily.B. Placing some “click” buttons in them.C.
15、 Allowing users to learn about the device.D. Allowing users to control switches in them.7. The last paragraph mainly shows that _.A. people are interested in the deviceB. the device requires people to type wordsC. the device is really easy for people to useD. some training is needed to use the devic

Uninterested.CRoyal Society for the Protection of Birds is an organization in the United Kingdom, which aims to protect birds. It announced on its site earlier this month that it has bought the natu
17、re reserve （自然保护区）at Dunnet Head, Scotland, after receiving money from Heritage Lottery Fund.Dunnet Head is the most northern point of mainland UK and the 40-acre site is a popular breeding （繁殖）ground for seabirds like puffins （海鹦）.The organization has been renting the reserve since May, 2019 from t
18、he lands owner, Ben Colson. “We owned the land at Dunnet Head for over a quarter of a century and our purpose is to make sure that it is not commercially （商业地）developed,” Colson told Royal Society for the Protection of Birds. “So, while we are sad to be ending our relationship with the land, we are
19、delighted to have been able to agree to this sale with RSPB. It will make sure that the land continues as a place of wild beauty.” Scotland is home to about half of Europes seabirds, according to The Scotsman.Ownership of the land by Royal Society for the Protection of Birds will help increase the p
20、uffins population.According to the World Wildlife Federation, puffins Latin name, Fratercula, means “little brother”. The puffin, known as “clowns of the sea” for its tri-colored beak, was listed on International Union for Conservation of Natures red list as “vulnerable （易危物种）” in 2019 because of a
21、dropping population. Although the puffins population is still in the millions, fewer young or breeding-aged birds are surviving. Their numbers are dropping, because food, like sand eel, is becoming harder for puffins to find, which is caused by pollution and oil spills （泄漏）.According to the World Wi
22、ldlife Federation, puffins usually breed with just one partner. Puffins, which the World Wildlife Federation says weigh about as much as a can of Coke, lay only one egg per year as well. So we need to work hard to protect puffins.9. Why did RiSPB buy the reserve at Dunnet Head?A. To develop it comme
23、rcially.B. To protect seabirds like puffins.C. To create a safe place for puffins to live.D. To get a lot of money from Heritage Lottery Fund.10. Ben Colson was willing to sell the reserve to RSPB because _.A. he knew it wouldnt be damagedB. he had to move away from ScotlandC. he could make a lot of
24、 money out of itD. he couldnt take care of the land himself11. Whats the main reason for the dropping population of puffins?A. They are being widely hunted.B. They cannot find enough food.C. They can lay only one egg per year.D. They are negatively affected by pollution and oil spills.DHistory was m
25、ade in 2019 when a Soyuz TMA-18M spacecraft （宇宙飞船）traveling from the International Space Station （ISS） landed somewhere in Kazakhstan. The landing was a cause for celebration as the craft carried American astronaut, Scott Kelly, and Russian astronaut, Mikhail Kornienko, home from their 340-day task
26、aboard the International Space Station.During their stay in space, the two astronauts orbited （围绕运动）Earth 5，440 times，covering a total distance of 143,840,000 miles! This allowed them to see more than 10,900 amazing sunrises and sunsets. Kelly completed three spacewalks while Kornienko took part in
27、one. The astronauts also performed many experiments to learn about the effects of spaceflight on the human mind and body.Though life on Earth may seem a little dull, Kelly is now doing the things he missed the most during his long stay at the International Space Station Spending time with family, sw
28、imming, and eating fresh produce.The astronaut, who announced his retirement nine days after the task ended, will continue to experience testing for a few months. Though the long-term effect will not be known for a few years, Kelly recently said, “I lost bone mass （骨量），my muscles became less, and bl
29、ood to my heart dropped.” But the astronaut has no regrets about being part of this task that may pave the way for future human space travel.Though this was the longest time spent in space by a US astronaut; it was not the longest time ever. That credit （赞扬）goes to Russian astronaut Valeri Polyakov,
30、 who spent almost 438 days aboard the Mir Space Station from January, 1994 to March, 2019. This, however, is the first time that the astronauts have been tested to understand effects that long space travel has on the human body.In Scott Kellys case, the scientists will be able to compare the test results with those of his twin brother, Mark Kelly, also a former NASA astronaut.
