Question

【题目】All living things need energy to live and grow. This energy comes first from the sun. Plants use water and sunlight to make their own food. Animals can not make their own food, and they eat plants. Other animals then eat the plant eaters.

A food chain shows what eats what. It might show that zebras eat grass and then lions eat zebras.

Lions also eat other animals. Zebras eat other kinds of plants. So it takes more than one food chain to show how lions and zebras get their energy.

A food web shows how food chains work together. From it we can see how energy moves from plants to animals.

Plants and animals that live in hot, dry deserts depend on water as well as food. Creosote bushes have small leaves that hold water. Their seeds provide food and water for kangaroo rats. Kangaroo rats don’t need to drink water. They get all the water they need from the plants they eat. Kangaroo rats keep cool by coming out only at night to look for food. Ringtail cats also come out only at night. Ringtail cats hunt and eat kangaroo rats. Coyotes eat both the kangaroo rats and the ringtail cats.

Nothing is wasted in a food wed. Vultures eat dead animals. Vultures are scavengers. Scavengers do not hunt and kill other animals to get food. They eat animals that are already dead. When a ringtail cat or a coyote dies, it makes a meal for the vultures. Scavengers do an important job in keeping the environment clean.

Answer 1

【答案】

【1】C

【2】D

【3】B

【4】B

【5】A

【解析】这是一篇科普说明文，短文中给我们介绍了自然界中的食物链和食物网，并通过举例介绍了食物链是如何运作的。

【1】细节理解题。根据短文的开头All living things need energy to live and grow. This energy comes first from the sun.可知，所有的生物都需要能量来成长，这种能量首先是来自太阳，由此可知应选C。

【2】细节理解题。根据短文第四段中Kangaroo rats keep cool by coming out only at night to look for food. Ringtail cats also come out only at night. Ringtail cats hunt and eat kangaroo rats.可知，浣熊在晚上出来是为了捕杀长鼻袋鼠吃。由此可知应选D。

【3】细节理解题。根据短文最后一段Vultures eat dead animals. Vultures are scavengers. Scavengers do not hunt and kill other animals to get food. They eat animals that are already dead. When a ringtail cat or a coyote dies, it makes a meal for the vultures可知，浣熊和土狼死了之后，秃鹰会吃他们的尸体，它是一种食腐动物，吃所有动物的尸体。图片中展示的是一个食物链，在最高级的这一个应选B。

【4】推理判断题。根据短文第一段Animals can not make their own food, and they eat plants. Other animals then eat the plant eaters.可知，植物处在食物链的最底层，不是最高层，故B是错误的。根据then lions eat zebras. Lions also eat other animals可知A正确；根据短文最后一句话Scavengers do an important job in keeping the environment clean.可知C正确；根据Kangaroo rats don’t need to drink water. They get all the water they need from the plants they eat.可知D正确。

【5】主旨大意题。这篇短文给我们介绍的是自然界中的食物网，它可以告诉我们食物链是如何协作的，文章还以沙漠中的动物为例，给我们介绍了食物网。因此A选项点明了文章的主题词，最符合文意，故选A。
