英语试题
Ⅰ.语法单句填空
1．We have come to the ________(conclude) that it would be unwise to accept his idea.

2．Children________(expose) to difficult situations are better at handling those________(challenge) tasks.
答案：exposed；challenging　考查非谓语动词。句意：暴露在困难处境中的孩子更容易处理那些富有挑战性的工作。第一空选exposed，因为expose与前面的the children构成逻辑上的动宾关系，所以选过去分词；第二空challenging意为“挑战性的”。
3．________(blame) for the terrible accident, the director felt nervous and was at a loss what to do.
答案：Being to blame　be to blame“该受责备，应承担责任”，此处指主管为这起重大事故负责，be to blame是固定用法，不用于被动语态。
4．The number of the foreign tourists to visit the US is expected to be more than 2 million by 2015, ________(contribute) 14 billion dollars to the US economy.
答案：contributing　考查非谓语动词。句意：到2015年为止到美国的游客数目有望超过两百万，会对美国经济贡献140亿美元。现在分词短语在句中作结果状语。
5．— What are the workers talking about?
—They are discussing the idea the old worker put ________ at the meeting yesterday.
答案：forward　考查动词短语。句意：——工人们在谈论什么？——他们在讨论那位老工人昨天在会上提出的想法。put forward“提出”，符合句意。
6．In the following two hours, she was ________(absorb) in film, so she didn't notice what happened around her.
答案：absorbed　考查动词短语意义。句意：在接下来的两个小时里，她在专心看电影，因而没有注意到周围所发生的事情。be absorbed in sth.“全神贯注于某事”。
7．Emily felt very sad that she was suspected ________providing false statements in court.
答案：of　考查动词搭配。suspect sb. of (doing) sth.“怀疑某人做了某事”。
8．Shenzhou Ⅸ spacecraft, ________(send) up into space on June 16, 2012, docked with Tiangong­1 successfully.
答案：sent　考查过去分词作定语。因为神舟九号和送入太空之间存在被动关系，而且动作已经完成，所以用send的过去分词表完成和被动。
9．The new suspension bridge ________(design) by the famous architect is ________construction now.
答案：designed; under　考查动词词义及短语搭配。句意：这位著名的建筑师设计的新悬浮
桥正在建设之中。句中design与suspension bridge之间是动宾关系，故第一个空用designed，相当于which was designed；under construction“在建设中”为固定结构。
10．________ if these experiments were successfully completed would we think of going into humans.
答案：Only　考查短语。句意：只有当这些实验都成功完成后，我们才能考虑在人身上实验。only if“只有当……”。
Ⅱ.阅读理解
Talking plants might sound like characters in a fairy tale. But recent scientific studies have shown that plants communicate with each other and with other living things in a surprising number of ways. To understand them, scientists say, we just have to learn their language. Farmers are especially interested in what plants have to say.
“Plants are able to communicate with all sorts of organisms (有机体). They can communicate with giant bacteria, with other plants and with insects. They do this chemicall
y，” said Cahill, an Ecology Professor of the University of Alberta in Canada.
Plant scientists are just beginning to understand this chemical “language”. Cahill says studies have shown, for example, that plants can evaluate conditions in their immediate environment and take appropriate actions.  Plants have an ability, for example, to signal pain or discomfort caused by anything from temperature extremes to an insect attack. Jack Schultz, a professor of chemical ecology at the University of Missouri, says when a plant senses that it's being eaten, it cannot walk away from trouble; on the contrary, it will release a chemical vapor that alerts other plants nearby.
react to的用法“Their language is a chemical language, and it involves chemicals that move through the air that are easy to be changeable, and most of all are smells that we are familiar with，” Schultz explained.
“All plants responded to the attack by changing their chemistry to defend themselves，” Schultz recalled. “But we were quite surprised to find that nearby plants also changed their chemistry to defend themselves, even though they were not part of the experiment.”
Studies have also shown that plants under attack release pleasant chemicals. Those chemicals attract friendly insects that attack the pests eating the plant.
In the end, plants' ability to communicate their needs—and our ability to understand them—could help farmers reduce the use of poisonous chemicals, cut operating costs and limit damage to the environment.
文章大意：本文是一篇科普类文章，主要讲述了“植物的特殊语言”及功能，以及这种特殊语言对农业生产可能产生的指导意义。
1．The recent scientific studies have shown that plants can ______.
A．communicate with other living things in a chemical way
B．hardly react to any sudden change in temperature
C．use a very special chemica1 language which is familiar to us
D．respond to the attack by giving off poisonous chemicals
答案：A　细节理解题。根据文章第二段中的“Plants are able to communicate with all sorts of organisms (有机体)．.. They do this chemically.”可知，植物能够与其他生物通过化学方式进行交流。故答案选A。
