It’s official, not making your bed keeps you healthy. Dust mites (尘螨) present in everyone’s home can cause asthma, but they can not live in the dry conditions of an unmade bed.
The average bed is home to one and a half million mites, and they cause a number of common allergies (过敏症), as they chomp away on human skin in the night; and then produce the allergens which we inhale (吸入).
Dust mites grow in the warm humid conditions prevalent in the occupied bed, but they cannot multiply without moisture. So leaving the bed unmade during the day means that the water is not retained by the sheets, which means that the mites dehydrate (脱水) and die.
Researcher Dr. Stephen Pretlove who has developed a computer model to track how changes in the home can reduce a numbers of dust mites said, “We know that mites can only survive by taking in water from the atmosphere using small glands on the outside of their body.”
In the next stage of their research, the scientists are putting mite pockets into beds in 36 houses around the United Kingdom. This will test the validity of the computer model and will investigate how people’s daily routines affect mite populations.
Building features such as heating ventilation (空气流通) and insulation (隔热) will also be adjustable to monitor how the mites cope and react to different atmospheres.
Dr. Pretlove said the research had potential to reduce the ￡700 million spent treating mite-induced illnesses each year in the UK.
“Our findings could help building designers create healthy homes and health care workers point out environments most at risk from mites.”
Dr. Matt Hallsworth, of the charity Asthma UK, said, “House-dust mite allergen can be an important trigger for many people with asthma, but at present many people find they are inevitable.”What is the best title of the passage？

Donald Watson was a man who thought very much about the food he ate. He was born in yorkshire， England , in September 1910. And he died in November 2005, at the age of 95. That is a very great age. Watson explained that it was because he never ate any food from animals.
When he was a boy , Watson stayed on a farm. .He loved to see the animals. He said that they gave so much to people. And all the animals were so friendly. Then , one day , he saw a man killing a pig . He was very sad. . From then on, Watson decided that he would never again eat meat . Twenty years later he decided that he wouldn’t eat anything from animals, such as milk, cheese or eggs. He became vegan (素食主义者).
Watson formed a group called “The Vegan Society”. In its newspaper, The Vegan Society thought it was terrible and wrong to eat food from animals. At first, there were not many people who agreed with him . They thought it was crazy to do it .Most people thought it was too difficult and unhealthy. However, over time , more and more people began to agree with Watson and The Vegan Society.
People become vegans for many reasons. Watson and his friend stopped eating because they loved animals. They believed that it was wrong to hurt another living thing .
Now, people also become vegans for environmental reasons. Keeping animals takes a lot of resources(资源)， including water and food. Also, in some places, people are cutting down trees to create more land for cows. By avoiding food from animals, vegans hope to protect these forest areas.

You probably know that frogs hop ( 双足跳 ). But did you know that there’s a small frog in the Pacific Northwest that bellyflops（肚子先着水）? It’s called a tailed frog.
Dr.Rick Essner, who has been studying tailed frogs for the past few years, says, “ I’ve looked at thousands of jumps and have never seen them land on their feet like other frogs.” Most of the time, tailed frogs land on their stomachs and then bring their back legs in to prepare for another jump.
Essner forst noticed these frogs because of the way they swim. Other frogs kick both of their back legs at the same time. But when a tailed frog swims, it pushes first with one leg and then the other.
To try to find out why tailed frogs bellyflop, Essner and other scientists collected and filmed different kinds of frogs. They found that all of the frogs start their jumps the same way: they hold out their legs. The change comes in the landing. Tailed frogs can't move their back legs as quickly as other frogs do. Maybe they don’t need to. Tailed frogs live around water and quickly jump into the water to escape danger.
Early frogs developed around watery areas and could jump quickly into the water to escape danger. Scientists think those frogs blended in with (与…融合在一起) the green plants on the side of the rocky rivers, just like today’s tailed frogs. “Ｉwould guess that other animals would have problems detecting them, ” explains Essner. When other animals find those early frogs, the frogs could jump into the river. They didn’t need to continue hopping.
Tailed frogs and other kinds of frogs went their own ways about 200 million years ago. Tailed frogs stayed by rivers. Other kinds of frogs moved to places where new hopping skills allowed them to survive. What’s special about the detailed frog ?
| A．It has a long tail |
| B．It jumps on one foot |
| C．It stars its jump differently |
| D．It lands differently from other frogs. |
Why do tailed frogs bellyflop?
| A．They have never left the water to live . |
| B．They have trouble in holding out their legs |
| C．Their back legs can’t catch up while jumping.. |
| D．Their front legs develop better than the back ones. |
The underlined word “detecting” in Paragraph 5 means “______”.
| A．eating | B．killing |
| C．using | D．discovering |
When they are in danger, the detailed frogs would _________.
| A．jump into the water for protection |
| B．hop around quickly |
| C．hide in the green plants near the river |
| D．jump into the rock |
It is natural that young people are often uncomfortable when they are with their parents . They say their parents don’t understand them .They often think that their parents are out of touch with modern ways , that they are too serious(严肃) — too strict with their children and that they seldom give their children a free hand . It is true that parents often find it difficult to win their children’s trust(信任) and they often forget how they themselves felt when they were young .
For example , young people like to act on the spot without much thinking . It is one of their ways to show they have grown up and that they can face any difficult situation .
