A.exposed; feelingB.exposed; felt
C.exposing; feltD.exposing; feeling

分析 考查非谓语动词.句意:当人们暴露于危险时,人常常血压上升,感觉紧张焦虑.

解答 答案A.根据短语be exposed to,expose和men逻辑上是动宾关系,所以用exposed,when exposed to danger在从句中做时间状语,feel和men之间是逻辑上的主谓关系,所以用feeling,做伴随状语,故选A.

4.Plants are flowering faster than scientists predicted (预测) in reaction to climate change,which could have long damaging effects on food chains and ecosystems.
Global warming is having a great effect on hundreds of plant and animal species around the world,changing some living patterns,scientists say.
Increased carbon dioxide (CO2) in the air from burning coal and oil can have an effect on how plants produce oxygen,while higher temperatures and changeable rainfall patterns can change their patterns of growth.
"Predicting species,reaction to climate change is a major challenge in ecology,"said the researchers of several U.S.universities.They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.
The study,published on the Nature website,uses the findings from plant life cycle studies and experiments across four continents and 1,634 species.It found that some experiments had underestimated (低估) the speed of flowering by 8.5 times and leafing by 4 times.
"Across all species,the experiments under-predicted the speed of the advance-for both leafing and flowering-that results from temperature increase,"the study said.
The design of future experiments may need to be improved to better predict how plants will react to climate change,it said.
Plants are necessary for life on the Earth.They are the base of the food chain,using photosynthesis (光合作用) to produce sugar from carbon dioxide and water.They let out oxygen which is needed by nearly every organism on the planet.
Scientists believe the world's average temperature has risen by about 0.8℃since 1900,and nearly 0.2℃every ten years since 1979.
So far,efforts to cut emissions (排放) of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃this century-a point scientists say will bring the danger of a changeable climate in which weather extremes are common,leading to drought,floods,crop failures and rising sea levels.

29.What is the main idea of Paragraph 1?B
A.Plants'reaction to weather could have damaging effects on ecosystems.
B.The increasing speed of flowering is beyond scientists'expectation.
C.Climate change leads to the change of food production patterns.
D.Food chains have been seriously damaged because of weather.
30.We can learn from the study published on the Nature website thatC.
A.plants'flowering is 8.5 times faster than leafing
B.there are 1,634 plant species on the four continents
C.scientists should improve the design of the experiments
D.the experiments failed to predict how plants react to climate change
31.Scientists pay special attention to the study of plants becauseB.
A.they can prove the climate change clearly
B.they are very important in the food chains
C.they play a leading role in reducing global warming
D.they are growing and flowering much faster than before
32.What can be inferred from the last two paragraphs about the world's temperature?A
A.It needs to be controlled within 2℃in this century.
B.Its change will lead to weather extremes.
C.It is 0.8℃higher in 1979 than that of 1900.
D.It has risen nearly 0.2℃since 1979.

8.As a young ice-skater,I had flown pretty high,pretty quickly.My partner and I won the Canadian junior pairs championship when I was 14.Later I was thrilled to be picked to skate in the 2008Olympics in Beijing,China.But then everything came down.
We finished the 12th at the Games.I soon quit double skating and tried to continue in singles.But I wasn't good enough; I didn't even compete in the next two national championships.I felt like I was a somebody who had become a nobody.
I was 18and had just graduated from high school when my mom told me,"You can't just depend on skating to make a living.You'd better find a job."I knew she was right.So I found a job at a restaurant where I waited at table and did anything else that needed to be done.In fact,I worked so hard that I had never got the chance to have a break.No one cared about that I had been an Olympic skater; I was judged only by how hard I worked.
That job taught me so many things.I learned,for example,how to deal with people.As an athlete,this was new to me.One day a man loudly called me over to his table and complained,"This milk is sour.I am not drinking this junk!I want my money back!"It was near the end of my shift (轮班) and I wanted to tell him how rude I thought he was.But I had learned that"the customer is always right"and a smile can go a long way."I'm really sorry,sir.I'll get you a free cup."I said with a smile.When I brought him his coffee,his attitude changed.And he left me a tip!
My first job taught me that it is important to do your best at anything you try.I knew nothing about being a waitress when I started my job but by the time I left---when I decided to return to skating---I had earned a raise and my boss's praise.They meant so much to me.
41.How did the writer feel after she picked up single skating?C
A.Thrilled.
B.Confident.
C.Disappointed.
D.Proud.
42.What does the underlined word"this"mean?A
A.The job at the restaurant.
B.The job in the ice-skating.
C.The people around the writer.
D.The complaining man.
43.What did the writer do about the man's complaint?D
A.She told him how rude he was.
B.She gave his money back.
C.She asked her boss for help.
D.She apologized with a smile.
44.From the text we can knowB.
A.the author did very well at the 2008Olympics
B.the author was successful as a young ice-skater
C.the author didn't follow her mother's advice
D.the author gave up her skating career
45.The text is mainly aboutC.
A.the author's skating life             
B.a lesson from skating
C.the author's first job               
D.how to be a good waitress.
