Ⅲ.阅读理解
MIT researchers and their colleagues are working to find out whether energy from trees can power a network of sensors (传感器) to prevent spreading forest fires.
What they learn could also raise the possibility of using trees as silent guards along the nation’s borders to discover potential threats such as smuggled (走私的) radioactive materials.
The U．S. Forest Service currently predicts and tracks fires with a variety of tools, including remote automatic weather stations. But these stations are expensive and sparsely (稀疏地) distributed. Additional sensors could save trees by providing better local climate data to be used in fire prediction models and earlier warnings. However, recharging or replacing batteries by hand at very hard－to－reach locations makes it impractical and costly.
The new sensor system seeks to avoid this problem by developing trees into a self－sustaining power supply. Each sensor is equipped with a battery that can be
slowly recharged using electricity produced by the tree. “A single tree doesn’t generate a lot of power, but over time the trickle (细流) charge adds up, just like ________” said Shuguang Zhang, one of the researchers on the project and the associate director of the MIT’s Center for Biomedical Engineering (CBE)．
The system produces enough electricity to allow the temperature and humidity sensors to wirelessly send out signals four times a day, or immediately if there’s a fire. Each signal spreads from one sensor to another, until it reaches an existing weather station that sends the data by satellite to a forestry command center in Boise, Idaho.
Scientists have long known that trees can produce extremely small amounts of electricity. But no one knew exactly how the energy was produced or how to take advantage of the power.
28．What are the disadvantages of the remote automatic weather stations?
a. They cost too much.
b. They are of poor quality.
c. They are not enough.
d. They can’t reach remote places.
A．a, bB．b, dC．a, cD．b, c
29．Which of the following is the best sentence to fill in the blank?
A．Far water does not put out near fire.
B．All rivers run into sea.
C．Many a little makes a mickle.
D．It never rains but it pours.
30．What Shuguang Zhang said in Paragraph 4 means that ________.
A．a single tree is enough to generate much power
B．the power from the tree can’t be stored
C．trees can generate enough power for our life
D．a tree can produce the electricity to meet the needs of a sensor
31．What would the author talk about after the last paragraph of the passage?
A．The amount of electricity trees produce.
B．How trees produce electricity.
C．Trees’ contribution to society.
D．The research process of tree power.
32．What would be the best title for the passage?
A．Preventing forest fires with tree power
B．Trees can produce electricity
C．Tree power in daily life
D．Developing new energy
Ⅳ.阅读简答
The earthquake and tsunami have caused huge human and material losses in Japan, and the threat of unclear radiation has added to people’s sadness. Some of the factories will have to move outside the country to ensure its business.
Owing to the level of the damage to Japanese factories and infrastructure, it will be weeks or even months before the country’s supply chain returns to normal and its manufacturing level gets back to its previous level. While most factories will be running as usual in the next few months, it is likely that some of the older and less efficient ones will be shut down. It will thus be cheaper and easier to use manufacturing bases in China and other low－cost countries than to rebuild the factories in Japan.
One example of the changes in Japanese companies’ strategy is that less than half of the automobile manufacturing capacity of Toyota, Nissan, and Honda is in Japan. With the triple disasters affecting in Japan, its automobile companies are expected to keep increasing manufacturing outside the country, and China looks like an appropriate destination for that.
A similar strategy applies to consumer products such as TV sets, music players and mobile handsets. Companies such as Sony have already moved much of their manufacturing to other countries, and this trend will continue. The production of many semiconductor products will steadily move outside Japan, too with perhaps the establishment of strategic relationships with other countries.
Is this trend bad for Japan? No, if new industries are built to take advantage of the opportunities in the global market to ensure a better future.
33．What has contributed to the Japan’s disaster? (No more than 9 words)
________________________________________________________________________
34．List two different kinds of products that have already moved their factories outside Japan.(No more than 7 words)
________________________________________________________________________
35．Why won’t many Japanese factories plan to rebuild but turn to foreign bases after the disaster？(No more than 8 words)
________________________________________________________________________
36．What is the main idea of the passage？(No more than 10 words)
________________________________________________________________________
________________________________________________________________________
课时作业(九)
Ⅰ.1.A 考查形容词辨析。句意：你意识到学习外语的重要性了吗？这四个形容词意为对某件事很留心或很注意。aware 意指通过自己直觉，如根据别人的态度或者依靠某种信息方式而得到的认识；sensible 指通过感性知觉或通过直觉得到的认识；awake意为清醒的；conscious 强调某种感知到或感觉到的认识。be aware of 或者be conscious of而sensible和awake不可用of结构。
2．C 考查副词辨析。especially特别，尤其；luckily幸运地；unfortunately，意思是“令人遗憾地，不巧，可惜”；naturally自然地。根据句意可知选C项，在句中用作插入语。
3．B 考查部分倒装。那个男孩对英语一无所知，我也是。此句为一个否定而且只谈到两个人，应用“neither”。
4．A 此句考查的是“主语＋is said＋to do…”中的不定式的时态。从句中的already常与完成时态连用。leave所表示的动作发生在is said之前，故leave应用不定式的完成式；又因为leave与he之间是主动关系，不能用被动式，所以选A。
5．B 考查There is no doubt that...和there is no doubt of/about...两个句型，用来表示“对某事确定无疑”。从句子的意思来看，只有B合适。第一个句中的that 从句为同位语从句，主句为否定式时，从句用that引导，主句为肯定式时，从句用whether/if引导。
6．B 考查交际用语。句意：——我已经把园艺作为我的嗜好。你有什么建议吗？——继续努力吧！A项意为“你会成功的。”，B项意为“继续努力吧。”，C项意为“别提了。”，D项意为“别紧张，慢慢来”。根据四项基本含义可知应该选择B项。
7．D 考查非谓语动词。judging by… 常用作评判性状语。故答案应为D。
8．D 考查倒装和词语辨析。当表示地点的介词短语置于句首时，句子全部倒装。同时根据宾语a new look可知take on是“呈现”之意。
9．C 考查主谓一致。Mr White为句子主语。
10．A 考查名词性从句和定语从句。第一个空用what引导表语从句，在句中作表语。第二空为定语从句，when在定语从句中作时间状语。
11．D 考查谓语动词的用法。第一空the young 意思为“年轻人”表示复数意义，故谓语动词要用复数形式，且用主动语态；第二空谓语动词用单数形式，且用被动结构，选项B第一空为被动结构，不符合句子意思。
12．C 考查非谓语动词。from的宾语用动名词形式，又根据cut down与trees是被动关系可知选C。
13．A A little bird told me用于不想说出是谁告诉的，意思是“有人告诉我的，不告诉你我是怎么知道的”。
