17．If we ________ materials like empty tins，old clothes and so on，our natural resources will last longer．（　�。�

A．

reuse

B．

recycle

C．

reduce

D．

renew

分析如果我們循環(huán)使用空瓶子或舊衣服這類的材料，我們的自然資源可以用好久．

解答答案：B，考察動詞辨析．由題意可知，想表達的含義是"循環(huán)使用"，A選項"再利用"，強調(diào)一次；B選項"循環(huán)利用"，強調(diào)多次循環(huán)；C選項減少，D選項更新，由此可知，選擇recycle，表示重復(fù)循環(huán)使用以節(jié)省資源，因此選擇B．

點評此題考查動詞短語的固定搭配，應(yīng)在了解句子含義的前提下，根據(jù)選項詞語本身詞義進行擴展，以此選擇正確答案．

7．We all know that zebras have stripes （條紋）．But why？It's hard to get a black-and-white answer．This is a question not just common people like us have asked，but scientists too．
Several studies have been done to find out the reason behind the stripes and many theories （理論）have been suggested．According to a recent study，the type of stripes changes depending on the temperature where zebras live．The warmer the place is，the more stripes they may have．From this study，scientists believe that stripes may help to keep a zebra cool in warmer places．
According to the cooler temperature theory，when air hits a zebra，the movements of air are stronger and faster over the black parts and slower over the white．This is because black color takes in more heat than white．So at the point where the black and white meet，there is cooling airflow．It can quickly cool a zebra's skin!In fact，scientists have noticed that heavily striped zebras have 5.4T lower skin temperature than other animals without stripes in the same area．
Some scientists believe that stripes may be an adaptation （適應(yīng)）by zebras to defend （防衛(wèi)） themselves from the horseflies that follow zebras．The cooler temperature theory  holds merit  here too，since disease-carrying flies like horseflies like it hot．Flies also don't like landing on striped surfaces．
There also have been many other theories that have been suggested for why zebras have stripes．Some explanations are very common．One of them is that stripes may help zebras hide in grass especially from lions．Lions are color blind and even if they are not far away they may see stripes as grey and be confused by them．What's more，zebras are a large group of animals living together．When a number of zebras stand or move together，stripes may confuse lions into thinking it is one large animal．

48．Stripes are helpful for zebras toA．
A．stay cool
B．move together
C．live in cold places
D．fight against diseases
49．How do zebras'stripes protect them from lions？D
A．Lions may be frightened away by strips．
B．Lions may see stripes as many animals．
C．Stripes can prevent zebras from being seen．
D．Stripes may make lions confused．
50．The underlined words"holds merit"in Paragraph 4probably mean"A"．
A．works well
B．sounds unreasonable
C．causes disagreement
D．needs supporting facts
51．What is the passage mainly about？C
A．Why lions can't eat zebras．
B．How horseflies keep away from zebras．
C．Why zebras have stripes．
D．How animals adapt to nature．
