【题目】By not having a child, the carbon footprint of an individual ________ in a developed country would be reduced on average by an extra 58.6 tons of carbon dioxide every year, ________ current emission rates.

A. lived; basing on B. living; basing on

C. lived; based on D. living; based on

【答案】D

【解析】考查非谓语动词。句意：按照现在的排放速率，每少生一个孩子，发达国家每年的个人碳排放量将平均额外减少58.6吨。第一个空是作定语，修饰an individual，“一个人”主动“生活”，故用v-ing形式；第二个空表示“以……为根据”，是base A on或be based on，本空是作an extra 58.6 tons of carbon dioxide 的后置定语，base与前面提到的数据是被动关系，故用过去分词。综合以上，故选D。

Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea. People in Britain were much slower in finding out what tea was like, mainly because tea was very expensive. It could not be bought in shops and even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity. Some of them were not sure how to use it. They thought it was a vegetable and tried cooking the leaves. Then they served them mixed with butter and salt. They soon discovered their mistake but many people used to spread the used tea leaves on bread and give them to their children as sandwiches.
Tea remained scarce and very expensive in England until the ships of the East India Company began to bring it direct from China early in the seventeenth century. During the next few years so much tea came into the country that the price fell and many people could afford to buy it.
At the same time people on the Continent were becoming more and more fond of tea. Until then tea had been drunk without milk in it, but one day a famous French lady named Madame de Sevigne decided to see what tea tasted like when milk was added. She found it so pleasant that she would never again drink it without milk. Because she was such a great lady that her friends thought they must copy everything she did, they also drank their tea with milk in it. Slowly this habit spread until it reached England and today only very few Britons drink tea without milk.
At first, tea was usually drunk after dinner in the evening. No one ever thought of drinking tea in the afternoon until a duchess（公爵夫人）found that a cup of tea and a piece of cake at three or four o'clock stopped her getting “a sinking feeling” as she called it. She invited her friends to have this new meal with her and so, tea-time was born .

【题目】根据短文理解，选择正确答案。
Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.
Years ago, over hunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.
The 21st century brings a different challenge to elephant conservation —land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.
Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.
AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.
The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.
（1）The first paragraph of the text is mainly to tell readers _____.
A.African elephants are endangered now
B.there remains a lot to do to protect African elephants
C.African elephants are popular animals
D.the number of African elephants has increased over the years
（2）What is the biggest difficulty in protecting African elephants now?
A.They are still being killed.
B.Their habitats are being destroyed.
C.They don't have enough food.
D.They can't live in peace with farmers.
（3）To protect elephants, the AWF does all the following EXCEPT _____.
A.keeping elephants
B.protecting elephants' habitats
C.doing research on elephants
D.helping farmers improve their life
（4）What is the best title for the text?
A.African elephants conservation
