Question

Did you know that vegetables can grow in the climates they are not used to? Cool climate vegetables like asparagus (芦笋) are now able to be grown in places as hot as Hawaii. In Hawaii, marine (海的)engineers have been able to actually let you believe such vegetables that they are living in cooler climates. In that way they grow faster and taste better. What these engineers have been using is very simply cold sea water. How did they use it? They place pipes in the soil and cold water flowing through them cools the earth. This causes plant growth and enables gardeners in tropical climates (热带气候) to grow crops from cooler climates. Also some of these pipes are exposed to the air and they make the air “wet” and thus water the gardens. What especially makes people happy about this process (过程) is that nothing to the natural conditions is being used. Another new use for cold ocean water is to cool buildings. Engineers believe that for example the entire west coast of the United States could be air-conditioned using seawater.

 

72. What does the new system enable the gardeners to do?

   A. Water the field with seawater.                          B. Grow asparagus in hot places.

   C. Grow cool climate vegetables in hot areas.        D. Cool the soil.

73. Sea water mentioned in the passage is mainly used to________.

     A. water the farms                                               B. water the gardens     

     C. cool the air                                                      D. make the earth cool

74. What is the report mainly about?

   A. How to grow vegetables in hot areas.              B. How to grow crops in tropical climates.

   C. How to cool the soil.                                     D. How to use sea water.

75. It can be inferred from the passage that ________.

   A. sea water can act as an air-conditioner

   B. asparagus are only grown in hot places

   C. the writer wants to tell us something about scientific advance

   D. sea water has many advantages

Answer 1

72. C。利用题目中的关键词雨，在原文中找到对应词语，在对应词语周围找到答案。A、B项均属于表面意思，且捕食原文中的具体事实，D项cool the soil不是最终目的。只有C项是具体事实：cool climate vegetables are now able to be grown．．．符合文中的the new system。

73. D。A、B、C项所述只是seawater所起的附带作用，并不是文章所指的主要方面，故正确答案为D。

74. D。找出多次重复的信息，它必定是主题。这类问题的典型形式是：What．．． main．．．／mainly．．．?要求考生指出文章的topic(论题)，subject(主题)，title(标题)，main idea(大意)等。seawater在原文中直接出现两次，间接出现三次：coldwater，cold ocean water，How did they use it? 等，故正确答案为D。

75. C。吃透作者意图，通过作者阐述的观点、叙述的事实等，避开表面现象，得出可靠结论。infer，imply (暗示)，suggest，conclude，assume (suppose)等常用于这类题中。A、D项均为字面意思。B项过于具体，只有C项为作者的真正意图。
