Question

Do you know what are the World’s tallest animals? How do they sleep and drink?

You may think it's difficult for them to sleep, but they have no such problems because giraffes don’t often stop for a snooze(打盹). As they are so tall—males can grow up to 18 feet, giraffes actually have the shortest sleep requirement of all mamma1s哺乳动物), with an average(平均) of half an hour a day. When they sleep, they seldom lie down and sleep for minutes at a time, since it's difficult for them to get up again and it’s dangerous in the wild. But the giraffe in the zoo sleeps around 4.6 hours per day, mostly at night. It usually sleeps lying down.

Drinking Water may cause problems for the animals because their long necks are too short to reach the ground. To drink they must spread their legs in an uncomfortable position, which makes them easily hunted by other animals like Africa's big cats. As a result. thev get most of their water from the plants that they eat. They only need to drink water every few days.

试题分析：本文讲述了世界上最高的动物：长颈鹿的生活习性：它们是世界上睡眠最短的哺乳动物，动物园里的长颈鹿比野生的长颈鹿的日平均睡眠要长一些。喝水成了长颈鹿的另一困难，因为他们的长颈够不着地面。所以它们的主要水来自所吃的植物，它们隔几天才需要喝水。

1.(They sleep with an average of) half an hour(a day)/ For half an hour. 题意：生活在野外的长颈鹿每天睡多长时间？根据第二段的“with an average(平均) of half an hour a day.”（平均每天半小时）可知本题答案：(They sleep with an average of) half an hour(a day)/ For half an hour.

2.It usually sleeps lying down/It usually lies down to sleep. 题意：动物园里的长颈鹿通常怎样睡觉？由第二段最后一句：But the giraffe in the zoo sleeps around 4.6 hours per day, mostly at night. It usually sleeps lying down.（但是动物园里的长颈鹿每天大约睡4.6小时，主要是在夜晚。它通常是躺着睡）可知本题答案：It usually sleeps lying down/It usually lies down to sleep.

3.They must spread their legs in an uncomfortable position. 题意：要喝水，长颈鹿必须做什么？由最后一段中的：To drink they must spread their legs in an uncomfortable position.可知本题回答：They must spread their legs in an uncomfortable position.

4.It's about how giraffes sleep and drink (water). 题意：短文的中心思想是什么？短文主要介绍的是长颈鹿的生活习惯，从sleeping和drinking water两个方面介绍的。所以，可以回答：It's about how giraffes sleep and drink (water).
