A
[2016·育才中学联考二]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 (偷猎者) 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·昆明市摸底调研]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 (过滤器) 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.
面临着饮用水被污染的现象，科学家发明了一种特殊的纸张，可把脏水过滤成能饮用的水来提高人民的生活质量。
do we learn about the book from the text?
sells well around the world.
has pages with several functions.
is about environment protection.
can treat about 100 liters of water.
答案：B 事实细节题。从文中第三段可知答案。
does the underlined phrase “that part” in Paragraph 6 refer to?
sic texts. ntion presentation.
ting discussion. ncial support.
答案：A 词意猜测题。放到第6段中“that part”应指上文中提到的内容，即“the idea of classic texts”。
which country did not the researchers test the drinkable book?
ladesh. a.
h Africa. ica.
答案：D 事实细节题。从文中倒数第二段可看出未提到America。
is the main idea of the passage?
archers have found a way to save those being ill.
ions of people are in great need of drinkable water.
pages could provide safe drinking water.
ledge is as important as drinkable water.
答案：C 主旨大意题。从文中第一段可知选C。
st n./vi. 渴望;口渴 ful adj. 有害的
ent vt. 提出;呈现 essful adj. 成功的
ncial adj. 经济上的;财政的;金融的

Ⅱ.七选五(建议用时8′)
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
[2016·安徽示范高中联考]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.
e witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.
times we have no idea when to sign our names.
's the meaning of your name?
onsibility is the name of the game.
or no name?
governments and many organizations will not process written complains if they do not bear the writer's signature.
e are people who wish to remain anonymous (匿名的) for various reasons.
本文阐述的是在当今社会签署姓名的重要意义。
1.D 根据空格所处的位置可知，该题应选择概括第一段内容的主题句，结合上文的内容可以判断D项正确。
2.F 根据上文讲述的商业合同以及银行文件需要签署姓名，可以得知答案为F项，内容相似。
3.G 下文的内容表明，此段讲述的是匿名的几种情况，故选G项。
4.A 结合3空的主题内容以及空前讲述的几种匿名的情况，可知答案是A。
5.E 根据下文“The answer is...”可知该空是一个问题，结合上下文可知这里是议论是否该留下姓名，故选E项。
Ⅲ.语法填空(建议用时8′)
阅读下面短文，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。
[2016·唐山摸底考试]Why send a greeting card when you can send a potato?

1.________ 2.________ 3.________ 4.________
5.________ 6.________ 7.________ 8.________
9.________ 10.________
本文讲述的是一种新型的问候方式，在土豆上留言，并通过电子途径发给收件人。
1.potatoes 考查名词。根据空格前为形容词，后为介词，可知此处填名词复数(注意变化规则)。
make 考查非谓语动词。the chance to do sth.“不定式作定语”。
lly 考查词性转换。修饰动词应用副词。
h 考查非限制性定语从句。从句中缺少主语且指物，故用关系代词which。
考查介词。此处后面为名词，且无提示词，通常为介词，结合语义可知填with，“使用……”。
mailed 考查动词时态和语态。mail与potato之间为被动关系，且全文用一般现在时态，故填is mailed。
uded 考查非谓语动词。include与cash之间为被动关系，且位于名词之后，故填included。
考查冠词。空前为系动词，空后为“形容词+名词”，故此处为冠词，表示泛指(a/an区别)。
r 考查代词。of one's own意为“某人自己的”，结合句子主语，可知填their。
考查形容词等级。空前为the，结合词意可知，此处表示收到的最好的东西。

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，

Cars were since my arrival in Beijing last year, I've found the opposite is e are millions of cars. However, people still use their bicycles to get around. For many, it's the easiest and cheapest way to travel today. Bicycles also come in different colors—silver, green, red, blue, yellow, whatever you want.
It's fun people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks. Bicycles allow people the freedom to move about that cars just can't provide.
Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started home.
My first ride home was orderly. To be safe, I stayed with a“pack”of bikers while cars on the streets came running swiftly out of nowhere at times. I didn't want to get hit. So I took the ride carefully.
Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide, so crossing took time, skill and a little bit of luck.
I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.

[2016·河南名校联考]Deep in the western Amazon rainforest, live butterflies that drink turtle tears. That sounds like a line straight out of a fantasy novel, but it's one hundred percent real life! It's an unusual sight—a crowd of butterflies flying around the eyes of yellow-spotted river turtles, trying to get a little tears. The poor turtles try to avoid them, but the butterflies insist drinking their tears until they've had their fill.
The butterflies are likely attracted to the turtles' tears because the liquid drops contain salt, specifically sodium (钠), an important mineral that is rare in the western Amazon rainforest, said Phil Torres, a scientist who does much of his research at the Tambopata Research Center in Peru and is associated with Rice University. Turtles get plenty of sodium through their largely carnivorous (食肉的) diet. Meat contains significant levels of the salt, Torres told LiveScience. But herbivores (食草的) butterflies sometimes struggle to get this extra mineral source， he added.
Torres explained the western Amazon rainforest is lower in sodium than many places on earth, because it is over 1,000 miles away from the Atlantic Ocean—a main source of salt. The region is also cut off from the mineral dirt blown towards the west from the Andes Mountains. Most of these windblown minerals are removed from the air by the rain before they have a chance to reach the western Amazon.
In fact， the butterflies have other sources to get sodium besides turtles' tears, which include animal urine (尿), muddy river banks, sweaty clothes and so on.
People can't help wondering if the process is painful for turtles. Torres said it's not completely clear, but the teary effort probably has little effect on the turtles, other than perhaps making them more vulnerable to their enemies like big cats, since the butterflies can block out their vision.
在Amazon rainforest的深处，居住着一种特殊的蝴蝶，它们喝海龟的眼泪。
butterflies drink turtle tears to________.
the turtles get sodium
a mineral from turtle tears
waste from the turtles' bodies
turtles to the best water source
答案：B 事实细节题。从文中第二段最后一句“But herbivores (食草的) butterflies sometimes struggle to get this extra mineral source.”可知选B。
third paragraph mainly tells us________.
leads to the extremely low levels of sodium in the region
sodium is very important for butterflies in the region
takes away the sodium of the surface of the region
the region is badly short of the mineral dirt
答案：A 主旨大意题。从第三段第一句话可概括本段大意。
can conclude from the passage that________.
butterflies like eating meat for getting salt
turtles like the butterflies drinking their tears
le tears are the only source of salt for the butterflies
Andes Mountains lies east of the western Amazon rainforest
答案：D 推理判断题。从第三段最后两句话“The region is also cut off from the mineral dirt blown towards the west from the Andes Mountains.”可知D正确，其他三项与文中事实不符。
is the best title of the passage?
les' enemy or turtles' friends?
B.A line straight out of a fantasy novel
western Amazon rainforest's turtles
onian butterflies drinking turtle tears
答案：D 主旨大意题。D项直接说明了文章主旨内容，最为贴切。
ight adj./adv. 直的;直接地
act vt. 吸引
ificant adj. 意义重大的
ce n. 根源;源泉
ful adj. 痛苦的;疼痛的
fact 事实上;实际上

●Respect their belongings. One important way to show respect is to show regard for the things important to your parents. For younger children, this may mean not touching jewelry or other valuable things. For grown children, respect may mean returning a borrowed tool in good condition and on time. Lack of respect for a parent's belongings is a violation of personal boundaries. __2__ And never borrow things without asking first.
●Punctuality.
__3__ Therefore, always be on time. For teenagers, showing up on time means coming home by curfew (宵禁). Adult children should show up on time for family dinners or events, or to pick a parent up for a medical appointment. Call if you're going to be late because parents worry about children, no matter their age.
●__4__ Remembering birthdays, anniversaries and other special days is a sign that you honor your parents. Make plans to take them to lunch or dinner or bake a cake or cookies. Most parents don't expect expensive gifts, but a handmade gift is always appreciated. A phone call from a grown child who lives too far for a visit is a welcome sign of respect.
●Be kind.
Kind words and affection are simple ways to show respect. Tell your parents you love them. Listen and allow your parents to speak without interruption. Show a sincere interest in what your parents have to say. Be patient with your parents and don't rush them. Never talk back or be rude or disrespectful. Acknowledge your parents' achievements. __5__
a good listener.
