六、阅读理解
26．阅读理解
The world
is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the Earth
is covered with water while we say we are short of（短缺）water. Why Because about 97%
of water on the Earth is sea water which we can't drink or use for watering
plants directly(直接地）. Man can only drink and use the
3%-the water that comes from rivers and lakes. And we can't even use all of
that, because some of it has been polluted(污染）.
Now more
water is needed. The problem is Can we avoid（避免）a serious water shortage later on First, we should all learn how to
save water. Secondly, we should find out the ways to reuse it. Scientists have
always been researching in the field. Today, in most large cities water is used
only once and then runs to the seas or rivers. But it can be used again. Even
if(即使）every large city reused its water, there would
not be enough. What can people turn to next
The seas
seem to have the best answer. There is a lot of water in the seas. All that
needs to be done is get the salt out of the sea water. This is expensive, but
it's already used in many parts of the world. Scientists are trying to find a
cheaper way of doing it. So you see, if we can find a way out, we'll be in no
danger of drying up.

【知识点】科普环保类；说明文
【解析】【分析】文章大意：地球不饥饿，但它干渴，因为我们只能使用全球水分的3%。为了避免缺水，我们首先要节约用水，其次是要找到再利用水的方法。最好的答案是从海水中分离出盐，但是这个方法成本很高。科学家们还在不断努力以找到经济有效的办法。
（1）细节理解题。根据文中语句Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly.因为地球上97%的水是海水，我们不能直接饮用或用它们来浇灌植物。故选D。
（2）推理判断题。短文说到：Man can only drink and use the 3% - the water that comes from rivers and lakes人们只能饮用和利用其中的3%，这3%的水来自河流和湖泊。因此河流和湖泊的水只占全球水的3%，故选A。
（3）细节理解题。Today, in most large cities water is used only once and then runs to the sea or rivers .今天，在大多数大城市水只是利用过一次就流入大海和河流。故选C。
（4）细节理解题。短文最后一段说最好的答案就是海洋，就是从海水中提出盐，但是很贵，科学家们在寻找廉价的办法从海水中提出盐。所以，找到便宜的办法才是最重要的。故选D。
（5）细节理解题。短文先介绍了地球的水资源很有限，接着讲了避免水缺乏的方法。所以文章的主题中心词就是thirsty，故选C。
【点评】考查阅读理解。本文主要考查细节理解题，首先仔细阅读文后的问题，弄清问题的大意；然后带着问题阅读短文，抓住关键信息，选择正确答案。

【答案】useful；in；a；valuable；But；throwing；factories；our；and；to turn
【知识点】语法填空
【解析】【分析】文章大意：水是我们生活的必需品，我们应该节约用水，并提及了一些方法或措施。
（1）句意：水是有用的。根据下文语句 We use water to cook rice. We use water to take showers. We use water to put out fires. 提示可知，水的用途很广泛，此句需要形容词，故填useful。
（2）句意：我们可以在湖和海中游泳。在海里或湖里要用介词in，故填in。
（3）句意：中国人在河中举行龙舟比赛。Dragon Boat Race是名词短语，龙舟比赛。因dragon的第一音素是辅音音素，要用不定冠词a，故填a。
（4）句意：水是有价值的。根据下文语句. It brings us happiness. Nothing can live without it. 可知水的价值很大。根据语境可知此句需要形容词，故填valuable。
（5）句意：没有它，什么都活不下去。但有些人每天都在浪费水和污染水。根据上下文语句Nothing can live without it. 与 some people waste water and pollute water every day. 理解可知，前后的语义是转折的，要用but来引导，位于句首首字母大写，故填But。
（6）句意：他们不停地向河流和湖泊扔垃圾。固定短语keep doing sth，不停地做某事，坚持做某事，故填throwing。
（7）句意：许多工厂甚至把废水排入河流。factory是可数名词，跟在many的后面要用复数形式，故填factories。
（8）句意：让我们尽最大努力节约用水，保持水的清洁。固定短语do one's best to do sth尽某人最大努力做某事，因主语是we，其对应的物主代词是our；根据语句中save water与keep the water clean是并列的关系，要用and来连接，故填our；and。
（9）句意：洗手后别忘了关水龙头。固定短语forget to do sth忘记做某事，故填to turn。
【点评】考查语法填空。通读全文理解大意，然后根据上下文或者所给单词的提示对所缺部分进行逐一解答。
六、阅读理解
26．阅读理解
The world
is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the Earth
is covered with water while we say we are short of（短缺）water. Why Because about 97%
of water on the Earth is sea water which we can't drink or use for watering
plants directly(直接地）. Man can only drink and use the
3%-the water that comes from rivers and lakes. And we can't even use all of
that, because some of it has been polluted(污染）.
Now more
water is needed. The problem is Can we avoid（避免）a serious water shortage later on First, we should all learn how to
save water. Secondly, we should find out the ways to reuse it. Scientists have
always been researching in the field. Today, in most large cities water is used
only once and then runs to the seas or rivers. But it can be used again. Even
if(即使）every large city reused its water, there would
not be enough. What can people turn to next
The seas
seem to have the best answer. There is a lot of water in the seas. All that
needs to be done is get the salt out of the sea water. This is expensive, but
it's already used in many parts of the world. Scientists are trying to find a
cheaper way of doing it. So you see, if we can find a way out, we'll be in no
danger of drying up.

B．75% of water on the Earth is from the sea.
C．97% of the Earth is covered with water.
D．3% of water on the Earth is sea water.
（3）From the passage we know that
A．if every large city reuses its water, we'll be in no danger of drying up
B．man can only drink and use about25% of water on the Earth
C．today in most large cities water is used only once
D．water can be used only once

（2）A
（3）C
（4）D
（5）C
【知识点】科普环保类；说明文
【解析】【分析】文章大意：地球不饥饿，但它干渴，因为我们只能使用全球水分的3%。为了避免缺水，我们首先要节约用水，其次是要找到再利用水的方法。最好的答案是从海水中分离出盐，但是这个方法成本很高。科学家们还在不断努力以找到经济有效的办法。
（1）细节理解题。根据文中语句Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly.因为地球上97%的水是海水，我们不能直接饮用或用它们来浇灌植物。故选D。
（2）推理判断题。短文说到：Man can only drink and use the 3% - the water that comes from rivers and lakes人们只能饮用和利用其中的3%，这3%的水来自河流和湖泊。因此河流和湖泊的水只占全球水的3%，故选A。
（3）细节理解题。Today, in most large cities water is used only once and then runs to the sea or rivers .今天，在大多数大城市水只是利用过一次就流入大海和河流。故选C。
（4）细节理解题。短文最后一段说最好的答案就是海洋，就是从海水中提出盐，但是很贵，科学家们在寻找廉价的办法从海水中提出盐。所以，找到便宜的办法才是最重要的。故选D。
（5）细节理解题。短文先介绍了地球的水资源很有限，接着讲了避免水缺乏的方法。所以文章的主题中心词就是thirsty，故选C。
【点评】考查阅读理解。本文主要考查细节理解题，首先仔细阅读文后的问题，弄清问题的大意；然后带着问题阅读短文，抓住关键信息，选择正确答案。
