　　Ⅰ.閱讀理解***建議用時15′***

　　A

　　[2016·育才中學聯考二]I went to the Tsavo National Park in northern Kenya for a film. We set off early for a distant water hole. A huge elephant covered with dry mud, drank calmly and deeply. He might have traveled 50 km to reach the water. He wasn't going to hurry now. He'd drink a while and rest in the shade, and then drink again or so we thought. What actually happened was that he drank deeply and stepped away. Then he suddenly fell down. Within minutes he was dead.

　　We called animal doctor Jeremiah Poghon immediately. He removed the head of a poisoned arrow from the elephant's body, and let out over 100 liters of pus ***胺***-the result of the elephant's meeting with a poacher ***偷獵者*** months before.

　　Today's poacher shoots from a blind. He fires an arrow, covered with poison, into the body of an elephant. If the poacher is lucky, the elephant might die in an hour or two; if not, he might have to follow the elephant for days before it dies. Often the arrow head fails to kill the elephant at once-it doesn't mean the poison won't finally kill the elephant, but it will be a slow death.

　　Living in Tsavo through these times, I could see the results of poaching from time to time. When I think about the death of that elephant, what stays with me is the extraordinary silence after the shocking sound of his body hitting the ground. I took some comfort from the knowledge that as the dead body returned to the soil, some animals would benefit-but I couldn't escape the feeling that with the death of such a large animal, the world seemed to be a poorer and emptier place.

　　[2016·昆明市摸底調研]The expression“a thirst for knowledge” may soon have a new meaning for millions of people who have no way to get clean water. Researchers have developed a book with specially treated pages that can turn dirty water into clean and drinkable water. They say their invention could improve the lives of many in the developing world.

　　About 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is polluted by harmful bacteria.

　　The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles ***微粒*** of silver. The pages can be used as filters ***過濾器*** to remove harmful microorganisms ***微生物*** that can pollute drinking water. The filter kills the organisms that pass through it.

　　Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages are made of filter paper. They are designed to be torn from the book. Water can be poured through the paper to be cleaned.

　　Ms Dankovich, the inventor, says each page can treat up to 100 liters of water. She recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she had considered adding classic literature on the book's pages.

　　“The idea of classic texts—that's of interest maybe later. We have discussed a little bit more exciting text. But we really haven't had the time to go through that_part，” she says.

　　Teri Dankovich and another researcher tested the drinkable book in Bangladesh, Ghana and South Africa. The tests proved to be successful.

　　Water for Life, a non-governmental organization, has provided financial support for the project.

　　面臨著飲用水被汙染的現象，科學家發明了一種特殊的紙張，可把髒水過濾成能飲用的水來提高人民的生活質量。

　　C.South Africa. D.America.

　　答案：D　事實細節題。從文中倒數第二段可看出未提到America。

　　Ⅱ.七選五***建議用時8′***

　　根據短文內容，從短文後的選項中選出能填入空白處的最佳選項。選項中有兩項為多餘選項。

　　[2016·安徽示範高中聯考]Many people write to newspapers and magazines to express their opinions. Letters to the editor must carry the writer's full name，address and telephone number, although the information is not necessary for publication. This requirement to provide personal particulars is a clear indication that the writers are held responsible for what they say. When a writer wants his voice heard, he needs to claim ownership of his voice. __1__

　　“People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship，”said social worker Ken Yip，“and this is what is causing a lot of family problems.”When we sign a paper, for example, a business contract or a bank document, the signature is a seal of consent, an agreement to take the matter seriously. __2__ The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.

　　__3__Multi-billionaire Mr King donates generously to charity several times a year. He gives simply because he wants to help but not for the publicity his donations may bring, and he does not want his good deeds to make news. In other cases, people insist on anonymity because they are afraid of the consequences of revealing their identity. __4__

　　__5__ The answer is very personal and lies in how much we want to get involved. We all have a name. It is a matter of responsibility to use it when we make a statement，a claim or an accusation. We all want to honor our own names, and it is only by stamping our expression of an opinion with our own name that we honor what we say.

　　A.Crime witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.

　　B.Sometimes we have no idea when to sign our names.

　　C.What's the meaning of your name?

　　D.Responsibility is the name of the game.

　　E.Name or no name?

　　F.Most governments and many organizations will not process written complains if they do not bear the writer's signature.

　　G.There are people who wish to remain anonymous ***匿名的*** for various reasons.

　　本文闡述的是在當今社會簽署姓名的重要意義。

　　1.D　根據空格所處的位置可知，該題應選擇概括第一段內容的主題句，結合上文的內容可以判斷D項正確。

　　2.F　根據上文講述的商業合同以及銀行檔案需要簽署姓名，可以得知答案為F項，內容相似。

　　3.G　下文的內容表明，此段講述的是匿名的幾種情況，故選G項。

　　4.A　結合3空的主題內容以及空前講述的幾種匿名的情況，可知答案是A。

　　5.E　根據下文“The answer is...”可知該空是一個問題，結合上下文可知這裡是議論是否該留下姓名，故選E項。

　　Ⅲ.語法填空***建議用時8′***

　　閱讀下面短文，在空白處填入適當的內容***1個單詞***或括號內單詞的正確形式。

　　[2016·唐山摸底考試]Why send a greeting card when you can send a potato? That's the reason behind one e­commerce site, which mails actual __1__ ***potato*** with personalized messages from their customers for $8 to $10. PotatoParcel offers customers the chance __2__ ***make*** a friend laugh or lighten the mood. The company __3__ ***usual*** offers their product in two sizes. For example, a “medium” potato, __4__ can fit 100 characters, is first picked by the senders. And then the company writes their note directly on the potato skin __5__ a special pen. After that the potato __6__ ***mail*** to the receiver in a “tiny envelope” from the company in Texas. There's no cash __7__ ***include*** inside—it is just __8__ actual potato with black writing. Past potato receivers have shared pictures of __9__ own experiences with others on social media. “The __10__ ***good*** thing I've received in the mail!” wrote one young woman, who got a potato from her boyfriend.

　　1.________　2.________　3.________　4.________

　　5.________　6.________　7.________　8.________

　　9.________　10.________

　　本文講述的是一種新型的問候方式，在土豆上留言，並通過電子途徑發給收件人。

　　1.potatoes　考查名詞。根據空格前為形容詞，後為介詞，可知此處填名詞複數***注意變化規則***。

　　2.to make　考查非謂語動詞。the chance to do sth.“不定式作定語”。

　　3.usually　考查詞性轉換。修飾動詞應用副詞。

　　4.which　考查非限制性定語從句。從句中缺少主語且指物，故用關係代詞which。

　　5.with　考查介詞。此處後面為名詞，且無提示詞，通常為介詞，結合語義可知填with，“使用……”。

　　6.is mailed　考查動詞時態和語態。mail與potato之間為被動關係，且全文用一般現在時態，故填is mailed。

　　7.included　考查非謂語動詞。include與cash之間為被動關係，且位於名詞之後，故填included。

　　8.an　考查冠詞。空前為系動詞，空後為“形容詞+名詞”，故此處為冠詞，表示泛指***a/an區別***。

　　9.their　考查代詞。of one's own意為“某人自己的”，結合句子主語，可知填their。

　　10.best　考查形容詞等級。空前為the，結合詞意可知，此處表示收到的最好的東西。

　　Ⅳ.書面表達***建議用時20′***

　　[2016·皖南八校聯考一]假設你是Abby，是學校英文報社“知心學長”欄目主編。一位叫Sophia的學妹來信反映自己有“拖延”的壞習慣。即使她有很多如做作業、彈琴等重要的事要做，也總是不由自主地把時間花在看電視、玩手機等瑣事上，為此她非常苦惱。請用英文給她回信，提一些建議。

　　內容包括：1.拖延的本質;

　　2.改正的建議。

　　注意：1.詞數100左右;

　　2.可以適當增加細節，以使行文連貫;

　　3.文章的開頭和結尾已給出，不計入總詞數。

　　參考詞彙：procrastination n.拖延，耽擱

　　Dear Sophia，

　　I am glad to hear from you. _________________________________ ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

　　In a word, don't spoil yourself. Although you have a long way to go, the first step is very essential. Good luck!

　　Yours，

　　Abby

　　One possible version：

　　Dear_Sophia，

　　I_am_glad_to_hear_from_you. To be honest, I sometimes have the same experience as you. But you have to know that procrastination is the thief of time. The following advice may help you overcome it soon.

　　The most effective means to solve the problem is that you can make a “to do” list. For example, you can write “Finish homework before Saturday night” on your plan. If you manage to finish it, you can reward yourself. Otherwise, punish yourself. What's more, you can find a person to remind you to finish work at any time. Then you can arrange your most important work at efficient times, like 8-10 o'clock. Different people base different efficient times. But it doesn't matter what time it is. Just don't waste time, following the schedule strictly. Last but not the least, do it now, just from now.

　　In_a_word,_don't_spoil_yourself._Although_you_have_a_long_way_to_go,_the_first_step_is_very_essential._Good_luck!

　　Yours，
