【推荐1】The world uses about a thousand million tons of water a day. Water is a human right(权利)and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean, safe water.

Treating wastewater is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80% of wastewater around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the wastewater.

While 75% of our planet is covered with water, only 2% is fresh water — that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in. More than 19, 000 factories have been built around the world, mostly in coastal countries. They process(加工) more than 92 million tons of water every day. But the technology they use requires a lot of energy.

Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough. But for now, the world still faces each day with not having enough water for everyone.

【推荐3】Taking away a city’s rubbish is a big job. Every day, trucks come into a city to collect it. Most rubbish is made up of things we can not eat or use. If we kept these things, we would soon have a mountain of rubbish.

In some cities the rubbish is collected and taken outside of a city to a dump. Often the city dump is a place where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewage system takes away the used water from toilets, bathtubs and other places.

To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or school may be built there, and then you’d never know that this had once been an old rubbish dump.

In other cities, the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where they are slowly changed into something called humus(腐殖质), which looks like black earth. It is rich with the kinds of things that feed plants and help make them grow.

【推荐1】Imagine this: you sit down and begin to eat a tasty tomato when, suddenly, it starts to scream (尖叫). While this thing will never really happen, a new study showed that plants can make sounds when they are stressed.

Researchers from Tel Aviv University in Israel did the study. They used ultrasonic microphones (超声波麦克风) to record the sounds of tomato plants in boxes.

Three groups of plants were listened to : One group wasn’t watered for five days, another group had the stems (茎) cut off, and the third group, was untouched. It turned out that the first two groups made sounds 30 to 50 times per hour at a frequency(频率)   of 40 to 80 kilohertz, while the untouched group only made the sound once per hour. “When tomatoes are not stressed at all, they are very quiet,” Lilach Hadany from the team told CNN.

The researchers don’t know how the sounds are made, but they believe the noise comes from the breaking of air bubbles in the plants. This means the noise produced by the plants is not intentional (故意的) or a form of active communication.

Although there’s no evidence(证据) that plants can intentionally communicate, animals and insects may be “listening in” to benefit from the sound. For example, the sound can tell moth that the plant is under stress and not suitable (合适的) to lay eggs on. An animal that wants to eat a plant could also use the sounds to make decisions, according to Science Focus.

After the experiment, the researchers listened to other plants such as wheat (小麦), corn and grapevine, and found they also made more sounds when stressed. Researchers said the study can benefit farmers in the future, as they can better take care of the crops(庄稼) by “hearing” how plants feel.

1. What is the finding of the study by researchers from Tel Aviv University? ________

A．Plants often feel stressed.

B．Some plants can scream.

C．Plants can make sounds when stressed.

D．Plants can communicate with each other.

2. Which one of the following groups can replace group two? ________

A．A group that is fully-grown.

B．A group which has its fruits picked.

C．A group that is watered regularly.

D．A group that has suitable temperature.

3. What does “active communication” in Paragraph 4 refer to? ________

A．Plants make sounds on purpose.

B．Plants receive messages from animals.

C．Plants make noise in a high frequency.

D．Air bubbles in the plants can break.

4. What might be the benefits of the finding? ________

A．It may help improve crop production.

B．It will help protect the environment.

C．It can help farmers predict weather.

D．It helps farmers decide what to plant.

5. What is the best title of the passage? ________

A．Plants can also “scream”	B．Tasty vegetables
C．How can vegetables make sounds	D．Imagination about vegetables
