【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.

【题目】阅读下面图文,简要回答所给问题。

Many people use their mobile phones as an alarm clock and more are used to returning messages before sleeping. However. these habits are becoming sleeping problems.

Several years ago, my boss used to stay up working on her mobile phone and got badly ill because of that. Now she always leaves her phone in another room at night. And she encourages friends to do so. “I sent each of my friends the same Christmas gift—an alarm clock so that they could stop using their phones as the alarm clock,” she said.

If your mobile phone wakes you up in the morning, it may also keep you up at night. A study in 2015 showed that people in mobile phone radiation(辐射) mostly had sleeping problems. And according to a Swedish study, more than half of young people feel like there must be phones around them. Most of them feel sorry for not returning messages. So they even have to reply to their friends before sleeping.

So what kind of people prefer to use mobile phones in their bedrooms? A recent study has shown that threequarter of people aged between 18 and 34 prefer to sleep with their phones near them. That number falls off a little in middle age, but only people aged 65 and the older are used to leaving the phone in another room while sleeping.
