B. 西南季风带来的丰沛雨水是南亚农业生产的主要水源

C. 南亚的农业以水稻种植为主

D. 西南季风势力的强弱对农业生产没有影响

【答案】D

【解析】

根据南亚热带季风气候的特征,进行分析解答。

南亚热带季风气候最显著的特征是一年可分为三季。35月的热季,西南季风尚未来临,高温少雨;610月的雨季,西南季风带来大量雨水,湿热多雨;从11月到次年2月为凉季,盛行干燥的东北季风,气候凉爽宜人。南亚热带季风气候对农业有非常重要的影响。每年西南季风带来的丰沛雨水,是南亚农业生产的主要水源。但由于西南季风到来的时间和强弱程度不一,因而降水的年际变率大,容易发生旱涝灾害,给农业生产造成不同程度的损害。故ABC都正确;选项D错误;结合题意。故选:D

【题目】Elephants are the largest living animals on land. For a long time, they are very helpful. They carry big trees, take people from place to place, and are even used as "living tanks(坦克) " in wars(战争). People work with elephants for ages, but they do not know elephants well enough. People don't think it's easy to hurt an elephant because its skin is thick and hard In fact, that's wrong. Sometimes, even though(即使)its skin is thick-up to 2.5 cm, a needle()can also be very dangerous for the elephant.

People say elephants are afraid of mice. This is wrong, too. In fact, elephants have very poor eyesight(视力),so they usually cannot see a mouse even if one comes very close to them. If a person has a good memory, people will say that he has an e1ephant memory. But up to now, no study shows that elephants have a better memory than other animals.

People also believe that when it is time for elephants to die, they will hide themselves in a so-called所谓的)" elephant graveyard(墓地)" Often, hunters try to find such places to get ivories(象牙),but few people really find places like that. In fact, when elephants are old or get sick, they will stay in deep and secret caves(洞穴)until they get better or die.
