It is the year 3000. I come to a place where I can’t see any water, plants or animals but black clouds in the sky and sand everywhere. It’s very dry so I drink some water that I carry with me. A native sees what I do and asks “What is it?” I pour some water and tell him it’s called water. “Oh, I’m so lucky that I can see water!” the man shouts in an excited voice. “You have never seen water? But how can you live without water?” I ask.

“Harry, get up, it is 7 o’clock, or you will be late!” a voice comes to my ears. “Oh! What a strange dream I dreamed just now!”

In class, I always think of that dream. And I also think of the fresh air, clean water, blue sky, green plants and animals in our world nowadays. How beautiful our life is!

But in order to make more money, people have built more and more factories. These factories send out waste smoke and water with chemicals which are harmful to the environment. The pollution is becoming worse and worse, and as a result, some animals and plants die out. With the development of agriculture, farmers spray aerosol (喷雾) and fertilizer, which also pollute the water and air. In the street the cars and buses are sending out heavy smoke which pollutes the air badly. Even tourism is harmful to the environment. When some tourists travel somewhere, they throw the plastic bags and rubbish onto the ground.

These behaviors are polluting the environment and the environment will become the greatest problem of the world. We shouldn’t pollute the environment any more. Otherwise more and more animals and plants will disappear. And maybe my dream will come true in the future.

1.In the place I come to, I can’t see　　　　 .

A.plants B.man

C.clouds D.sand.

2.From the passage we can infer Harry is the name of 　　　 .

A.a dog B.one of the author’s friends

C.the author’s sister D.the author

3.The author 　　　 the environment of the future.

The Colorado River is the lifeblood of the American Southwest. It supplies water to more than 36 million people, has changed the desert into farmland, and allows cities like Los Angeles, Phoenix, and Las Vegas to develop. But satisfying the region’s need for water has come at a price.

The river once traveled all the way from Colorado’s Rocky Mountains to the Gulf of California. Now, dams (水坝) control the river’s water for human use. As a result, the river no longer reaches the ocean. Without water, the delta (三角洲) at the river’s mouth has become dry and poor.

To bring the delta back to life, engineers recently opened the Morelos Dam near the US-Mexico border to free a temporary burst of water. This pulse flow allowed the Colorad River to reach the sea for the first time in 16 years, helping the river’s delta come alive.

The dams built by the US government form a system of man-made lakes. These lakes can store four times the river’s yearly flow. “The lakes are like the river basin’s bank accounts,” says Taylor Hawes. “They provide a place to save up water for not-so-rainy days — like right now”.

In wetter times, on and off since the 1960s, the Colorado managed to complete its journey to the sea. During those rare times, spring floods temporarily brought life back to the delta. Seeing the difference a little water could make gave scientists the idea for this year’s pulse flow.

“Just add water and you get an amazing recovery,” says Eloise Kendy. “The project serves as a model of how to manage rivers sustainably (可持续) for both people and nature. A lot of rivers in the West have problems. We used them to make the deserts bloom and build cities. We didn’t think about the environment. But it’s possible to restore them. If we can do it in the Colorado River Delta, we can do it anywhere.”

1.What can we lean from the first two paragraphs?

A.The Gulf of California is flooding.

B.The Colorado River’s delta is dying

C.The American southwest is becoming poor.

D.The water in the Colorado River is running out.

2.Taylor mentioned the bank accounts to show that ________.

A.lakes have stored much of the river water

B.many banks provided money to build dams

C.the money made from the lakes are kept in banks

D.people can borrow money from banks to buy lake water

3.What does Kendy want to express in the last paragraph?

A.Restoring deserts is sustainable for nature.

B.Many cities are built on deserts in the West.

C.Rivers in the West have been polluted seriously.

D.Environmental protection must go with development.

4.What is the main idea of the passage?

A.An effort to protect the Colorado River from drying.

B.An experiment to make the Colorado River flow freely.

C.A plan to bring the Colorado River’s delta back to life.

D.A way to make full use of the water from the Colorado River.

Swimming in the water of Hawaii’s Big Island is a fun experience. But it can be more exciting if there are dolphins swimming around and jumping out of the sea too. For many people, it would be a wonderful dream to swim with these lovely animals! However, this may not be good for dolphins. They may get hurt because of human interaction (互动).

Dolphins are active and usually look for food at night. In the day, they like to rest in shallow bays(浅湾). Many people think the dolphins are awake during the day as they swim. But when they sleep they rest half of their brain and keep the other half awake to breathe, so they may be sleeping even when they’re swimming in the water.

From 2010 to 2013, spinner dolphins (飞旋海豚) of Hawaii’s Big Island were exposed to human activities more than 82 percent of the time, according to Julian Tyne, a researcher at Australia’s Murdoch University.

The National Oceanic and Atmospheric Administration (NOAA) says disturbing the animals in their near-shore habitat could force them to swim to less favorable places, putting them at risk of attack by sharks and other animals. 

Besides, when people are around, dolphins become more active. Thus, they can’t get enough sleep. “Disturbing their resting behaviors can actually affect their long term health and the health of the dolphin population,” Ann Garrett of NOAA’s National Marine Fisheries Service told the Associated Press.

As a result, the NOAA wants to make rules to help protect the dolphins. For example, the agency (机构) may ban swimming with the Hawaii spinner dolphins. Or they may stop people from swimming in shallow bays when the dolphins are resting. Tour operators must also be taught to watch for signs to know when the dolphins are in their resting state.

1.Which of the following about dolphins is NOT true?

A. They spend most of their time sleeping at night.

B. They like to stay in shallow bays during the day.

C. They keep half of their brain awake while sleeping.

D. They may be sleeping even when they’re swimming.

2.When dolphins are disturbed in their near-shore habitat, they _____.

A. would swim to a crowded place　

B. could move closer to sharks

C. could become less active　

D. could likely sleep longer

3.Which activity is against the rules?

A. Swimming with the Hawaii spinner dolphins.

B. Swimming in bays where the dolphins live.

C. Making signs that show the dolphins’ resting state.

D. Making signs that show where the dolphins are.

4.What does the article mainly talk about?

A. What habits dolphins have.　

B. What spinner dolphins are.

C. How the animals live in the sea.　

D. How to protect dolphins near the shore.

All plant cells are capable of taking up water. Even dead ones do to a certain degree. Absorption（吸收）of water by dead cell walls makes wood become larger. In common land plants, the living cells of roots take up most of the water. Land plants without roots do exist, however. Those greenish-yellow lichens（苔藓）you see on rocks in the high mountains have no roots. Half a billion years ago, when water plants started to enter the land, the first land plants did not have roots.

Even among the flowering plants, one finds rootless forms. These flowering plants are “the higher plants” because they evolved（进化）recently and are thus considered higher on the evolutionary scale（进化度）. In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad. It is a relative of the pineapple. Even if this plant had roots, they would be of no use, because where the plant grows, it never rains. The plant gets its water only from the dew（露水）it collects at night, when its leaves cool off. Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open. If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies. In the southern United States and in Puerto Rico, one sees bromeliads growing high above the streets on the insulation（绝缘物）of electric wires. These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.

1．Wood becomes larger because of    .

A．dead cell walls                                           B．water entering dead cells

C．the growth of cells                                   D．the death of cells

2．The “bromeliad” is a plant that   .

A．has useless roots                                      B．is a pineapple

C．can grow anywhere                                 D．takes up water through its leaves

3．The most suitable title for this passage is “    ”.

A．Absorption of water by plants                     B．Rootless plants

C．Plants in the desert                                        D．Higher plants
