I was born with bad eyesight. At high school I couldnt read the blackboard. By the time I got to the university of

8、Bath to study Chemistry it had got to the point where I couldnt really see images at all, only the difference between light and dark. And a few years later, once I was in the first year of my PhD, I was almost completely blind.But climbing is my great passion. I started climbing when I was young. My

9、 dad taught me everything about climbing. When I was 11, I led my first climbing route outside. People are usually amazed when they discover that not only do I climb, but I also lead climbs.At university I joined the Mountaineering Club and was able to climb much more frequently. We had regular trip

10、s to indoor walls and weekends away outdoors. I developed a great circle of climbing friends and went on several trips to Europe. After these I started Alpine climbing and ice climbing, too.When my sight dropped to a level where I could no longer read, I thought I might have to give up leading. But

11、I never thought I would stop climbing. I just learnt to adapt with the support of my friends.People often ask me, “Why rock climbing? It doesnt seem like a good activity for a blind person.”But when I think about the danger, crossing the road is far more dangerous, and also, its something where Im n

12、ot in control.Its quite possible that I wouldnt be such a good climber if I werent blind. If I didnt have these challenges, it wouldnt focus me. That determination is built through my disability.When I reach the top of a climb, I dont get to appreciate the view, but the feeling of achievement is ext

13、remely good.Climbing is a way to prove my way of thinking in life which is that Im not disabled, I m blind and able.4When the author went to university, he .Acouldnt read the blackboard Bcouldnt figure out light and darkCnearly couldnt see images Dwas almost blind5What did the author do when he coul

14、dnt read?AHe thought about quitting climbing.BHe learnt to adapt with others help.CHe continued leading climbs.DHe went on several trips to Europe.6What can we learn from the passage?AThe author started climbing at the age of 11.BThe author began ice climbing when he got his PhDCThe author is afraid

15、 of crossing the road.DThe author views blindness in a positive way.7Which can best express the main idea of this passage?ANothing is impossible to a willing heart.BAll things are difficult before they are easy.CActions speak louder than words.DThe eye is blind if the mind is absent. When homework a

16、nd tests keep you up late at night, you may plan to make up for your lost sleep during the weekends. But is it useful?A study published in the journal Current Biology shows that the habit of sleeping in on weekends doesnt fix the damage that has been done by a lack of sleep during the week. Even wor

17、se, it may damage your health.In the study, which was conducted over 10 days, 36 healthy young men and women with different sleep requirements were divided into three groups. The first group were asked to sleep nine hours a night and the second group five hours a night. The members of the third grou

18、p slept for five hours on weekdays but rested as long as they wanted on the weekend.The researchers found that people who lacked sleep ate more snacks and gained weight quickly. However, this wasnt the case for the first group.That could be partially due to the shifting of the biological clock and c

19、hanges to certain body hormones, especially hunger hormones. In order to catch up on their sleep during weekends, people in the third group would eat later as a habit. So their biological clocks shifted, which also changed the production of hunger hormones.“The hormone leptin(瘦素) decreases appetite(

20、胃口), while the hormone ghrelin(饿素) increases appetite,” explained US researcher Vsevolod Polotsky. “Sleep shortage causes leptin to drop and ghrelin to rise, so youre hungry and eat more.”And even if they tried to sleep for as long as they wanted to during weekends, according to researchers, it was

21、still not enough because they found it difficult to fall asleep.Moreover, short and insufficient sleep schedules will lead to an inability to change blood sugar and increase the risk of metabolic(新陈代谢) disease in the long term.8Which of the following is true about the study?AParticipants were divide

22、d into two groups.BResearchers studied 36 children and adults.CIt lasted for more than two weeks.DEach group follow different sleep requirements.9What does the underlined word “shifting” in Paragraph 5 probably mean?Aincreasing Blacking Cchanging Dshortening10Why may people without enough sleep eat

23、more?AThey need to create more energy.BThere is less leptin in their bodies.CThey have a lower blood sugar.DTheir bodies produce less hormones.11What can be a suitable title for this passage?AAppetite Affects our Sleep QualityBSleeping in Causes Weight LossCCatching up on Sleep Harms Our BodyDMen an

24、d Women Sleep Differently In the distant past, our ancestors relied on stars to guide them on a clear night. Today, we have navigational(导航的)systems to help us find our way, the latest of which is the Beidou Navigation Satellite System (BDS).The BDS is entirely built by Chinese engineers. With the l

25、aunch of the last satellite from the Xichang Satellite Launch Center on June 23, the global network of 59 satellites has been completed. On July 31, Beidou started providing services covering our whole planet.Its difficult to imagine the great influence those satellites have on our daily lives. When

26、 you unlock one of Hellobikes bicycles, you are using the BDS. “The intelligent lock on each bike receives Beidou satellite signals and sends positioning information to the data center which will help collect big data on the bikes and predict users riding needs in advance according to the data,” Chu

27、 Yiqun, a manager of Hellobike mentioned. Users can also find shared bikes more accurately(精确地) thanks to Beidous global positioning accuracy of 2.34 meters.Beidou adopts a unique two-way communication system, including its ability to receive messages sent by people from areas with poor communicatio

28、n signals. Obviously this function isnt designed for users to chat online. Instead, it plays a role when disasters occur and communications are blocked.After the Wenchuan Earthquake in 2008, all ground-based communication facilities were interrupted. Though the first generation of Beidou could only

29、send 120 characters in a single message at that time, communication between affected areas and rescue(救援) centers was successful. Now, Beidous messaging ability has been increased to 1, 200 Chinese characters in a single message. It is widely used in disaster alarms, automatic identification and inf

30、ormation release.As Sun Jiadong, former chief designer of the BDS said: “The application(应用) of Beidou is only limited by imagination.”12What can we learn about the BDS from the passage?AIt was developed by Chinese and American engineers.BIt works better on clear nights.CIts last satellite was launc

31、hed on July 31.DIts able to provide global coverage for navigation.13Why does the author mention Hellobike in Paragraph 3?ATo stress the excellent positioning ability of the BDS.BTo show how the BDS makes peoples daily lives easier.CTo present the advantages and disadvantages of the BDS.DTo explain

32、how the BDS works.14What is Beidous two-way communication system designed for?ATo help people when communication signals are poor.BTo make users daily communication more fun.CTo allow users to chat online more freely.DTo collect data from users for the data center.15What does the underlined sentence in the last paragr
