Subterranean insects issue chemical warning signals through the leaves of the plant. This way, aboveground insects are warned that the plant is already "occupied".‎ ‎ Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean root-eating insects. Subterranean insects send out chemical signals through the leaves of the plant, which warn the aboveground insects about their presence. This messaging makes it possible for spatially-separated insects to avoid each other, so that they do not compete for, the same plant.‎ ‎ In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean insects and 'vice versa (反之亦然). It seems that a mechanism (机制) has developed through natural selection, which helps the subterranean and aboveground insects to communicate with each other. This avoids unnecessary competition.‎ ‎ Through the "green telephone lines", subterranean insects can also communicate with a third party, namely the natural enemy of caterpillars (毛虫). Parasitic wasps (寄生蜂) lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, as these help them find more insects for their eggs.‎ ‎ The communication between subterranean and above- ground insects has only been studied in a few systems. It is still not clear how widespread this phenomenon is, say the researchers.‎ ‎1. How do subterranean and aboveground insects communicate with each other?‎ ‎ A. By sending signals through the leaves.‎ ‎ B. By giving off particular smells.‎ ‎ C. By making soft and beautiful sounds.‎ ‎ D. By the signals sent by parasitic wasps.‎ ‎2. After finding a plant occupied by root-eating insects, aboveground insects will usually ________.‎ ‎ A. send out warning signals ‎ B. compete for the same plant ‎ C. choose to leave the plant ‎ D. fight with the root-eating insects ‎3. Aboveground insects will develop more quickly if their food plants ________.‎ ‎ A. are often visited by parasitic wasps ‎ B. are not occupied by mot-eating insects ‎ C. have more green leaves ‎ D. have more subterranean insects ‎4. What does the underlined part "a third party' in Paragraph 4 include?‎ ‎ A. Aboveground insects. B. Root-eating insects.‎ ‎ C. Caterpillars. D. Parasitic wasps.‎ ‎5. What would be the best title for the passage?‎ ‎ A. Communication between different insects ‎ B. How do animals avoid competition?‎ ‎ C. Insects use plants as telephones ‎ D. When plants have subterranean residents 答案：‎ ‎ 荷兰科学家研究发现：地下昆虫可以通过植物的叶子释放化学物质，作为信号对地上昆虫进行警告，从而避免对同一植物的竞争。‎ ‎1. A 细节理解题。根据第一段第二句Subterranean insects issue chemical warning signals through the leaves of the plant可知，地下昆虫能通过植物的叶子发出一种化学物质，作为信号对地上昆虫进行警告。故选A。 ‎ ‎2. C 细节推理题。第二段第一句Aboveground, leaf-eating insects ．．． root-eating insects提到，地上的昆虫更喜欢没有被地下昆虫占领的植物。联系本段最后一句This messaging makes ．．． for the same plant可知，当地上昆虫发现植物已经被地下昆虫占领时，它们通常会选择离开。‎ ‎3. B 细节推断题。根据第三段第一句In recent years it ．．． and vice ‎ versa可推知，如果植物没有被地下的食草昆虫占领，地上昆虫就会繁殖得快些。本句的意思是：近些年来的研究发现：如果地上昆虫赖以生存的植物被地下的食草昆虫占领，地上昆虫的繁殖速度就会减慢，反之亦然。‎ ‎4. D 词义推断题。第四段第一句的namely the natural enemy of caterpillars意为：也就是毛虫的天敌。a third party这里包含寄生蜂。‎ ‎5. C 标题归纳题。C项标题形象地表现出了昆虫间交流的独特方式，其根据在第一段第一句 ... insects can communicate with each other by using plants as telephones。‎ ‎4写作训练 ‎ ‎ 请根据以下资料说明，使用5个规范句子描述所给信息内容。‎ ‎ 世界上不同的地方社会习俗不同。比如，在美国两人第一次见面就彼此直呼其名。年轻人对老年人也都是这样。这在中国被认为是很不礼貌的。‎ ‎ 另外一个不同是交谈时可以谈些什么。询问别人大衣的价格，中国人觉得没什么，而美国人则认为很不礼貌。‎ ‎ (写作要求)‎ ‎ 1．标题；Social Customs between Americans and Chinese ‎ 2．必须使用5个句子介绍全部所给内容。‎ ‎ 3．将5个句子组织成连贯的短文。‎ ‎______________________________________________________________________________________________________________________________________________________________‎ ‎_______________________________________________________________________________‎ ‎_______________________________________________________________________________‎ ‎________________________________________________________________________________________________‎ 答案:‎ ‎ Social Customs between Americans and Chinese ‎ Social customs differ in different parts of the world. For example, the Americans call each other by their names when two people first met, and so does the young to the old. In china, it will be regarded as quite impolite to do so.‎ ‎ Another difference is about what can be talked about in conversation. A Chinese thinks nothing of being asked how much his coat costs while Americans think it impolite to ask such a question.‎
