【推荐1】Clothes are traditionally made of natural materials, such as cotton, leather and wool. They are all from plants or animals, but that doesn't mean they're friendly to the earth. For example, farmers have to use a lot of chemicals to grow cotton plants.

Scientists are now looking for new ways to make clothing materials. They hope the new materials are both comfortable and good for the earth. Scientists have worked out how to make materials out of corn husks(玉米皮), chicken feathers and rice straws.

"They used to be useless things. We always have a problem of how to deal with them," Yang, a scientist says, "Now, we can turn them into beautiful materials. Chicken feathers are better than other things. They have small air pockets like honeycombs. That means it will be very warm if you use them to make a jacket or sweater, and I think more and more people will like to buy these kinds of clothes."

【推荐2】Of all the things we eat and drink, water is the most important. Not all people know this, but it is quite true. Our body can be OK without food for a long time, but two or three days without water usually make people dead.

Many people are not clear about how much water our body needs, and usually they don’t drink enough, especially in hot weather. Most people drink water when they feel thirsty（口渴）. They often need more water especially when they do sports.

A man’s body is 65 to 70 percent water. If we don’t have enough water, we may feel tired and may become ill.

Now you see how important water is.

1. All the people know water is the most important thing for our body.
2. People will be OK if they don’t drink any water for five days.
3. Everyone knows how much water our body needs.
4. Most people need more water when they do sports.
5. According to the passage, half of the human body is water.

【推荐3】Our body language tells the world a lot about us. But can it change the way we see ourselves? The answer is YES.

There were two scientists called Amy Cuddy and Danna Carney. They knew much about body language and did famous researches(研究). According to the result of their researches, body language can change the chemistry of your brains. Some high-power body language can make you become confident. For example, you will feel confident when you hold your heads high or walk with your shoulders back. You will also feel confident when you put your arms out wide as if you win a race. However, some low-power body language can’t make you become confident. There are some examples, such as sitting with your arms close to the body, sitting with your legs together or walking with your heads down.

Why do all these happen? Some scientists think it’s because body language changes the amount of something special in our brains. It’s called hormone (荷尔蒙). One kind of hormone can increase (增加) your confidence. Another kind can increase your stress. But too much stress hormone is bad for learning. It increases the risk of health problems, too. The result of the research is helpful for your study. If you use more high-power body language in your study, you will be brave and confident. So, always believe you can study well, and then you will make great progress in your life.

1. According to the passage, which is NOT high-power body language?

A．

B．

C．

D．

2. Which word has the same meaning as the underlined word “stress” in Paragraph 3?

D．warning

3. What can we learn from this passage?

A．Body language can not change the way we see ourselves.

B．People with stress hormone only have more health problems.

C．Sitting with our arms close to the body can make us confident.

D．Using high-power body language can often help us study better.

【推荐2】Luca Gamberini has been scuba diving (戴水肺潜水) since he was a kid. His family owns a scuba company. For the past three summers, Luca has added gardening to his underwater activities. He helps run Nemo’s Garden, a project to grow plants in the sea.

From May to September, Luca and other divers are working on Nemo’s Garden in the Mediterranean Sea, 150 feet from the coast of Noli, Italy. Five large balloon-like objects, called biospheres (生物圈), hold plants such as beans and strawberries. The biospheres are filled with air and placed 20 feet below the water. “My father came up with the idea because he loves gardening very much,” Luca said.

According to Luca, the sea is a good place to grow plants because underwater temperatures (温度) are stable, changing little from day to night. The biospheres are like greenhouses. Inside the air-filled biospheres, fresh water keeps evaporating (蒸发), providing (提供) the plants with a good environment to grow in. “We have already seen the plants grow faster and better,” Luca says. “And there are fewer storms that can knock down the biospheres in the summertime.”

Luca hopes Nemo’s Garden will provide a new way of growing crops. “There is not enough land on the Earth,” he says. “And in many countries, bad conditions make it difficult for crops to grow.”

Though the project has just started, Nemo’s Garden has had success and is moving to different areas. “We’re going to try growing other plants,” Luca says. “We hope to set up biospheres around the world. There are many possibilities.”

1. Nemo’s Garden is a project to_________.

A．do scuba diving in the sea	B．stop storms in the sea
C．make fresh water from the sea	D．grow plants under the water

D．合适的

3. The passage is probably taken from the ________ part of a newspaper.

A．travel

B．science

C．health

D．sports

【推荐3】Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻击) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet, the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨头). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.
