【题目】 Are you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Now, scientists are trying to understand shyness. They have some interesting ideas about why people are shy.

Is it possible to be born shy? Many scientists say yes. Interestingly, these shy babies usually have shy parents. As a result, scientists think that some shyness is genetic (遗传的).

Family size might cause people to be shy as well. Scientists found that 66 percent of shy children had older brothers and sisters. At the same time, children with no brothers and sisters may be shy as well. Growing up alone, they often play with themselves. They are not able to learn the same social skills as children from big families.

You may also be shy because of where you were born. Scientists found surprising differences about shyness in different countries. In Japan, most people said they were shy. But in Israel(以色列), only one of three people said so. What can explain the difference? One scientist says the Japanese and Israelis have different opinions of failure.

For shy people, it can be difficult to make friends and speak in class. But scientists say you can get over your shyness. They suggest trying new things and practicing conversations. And_don't_forget—if_you_are_shy,_you_are_not_the_only_one.

【题目】 One of the hottest places on the earth is Death Valley. It's a desert valley in North America. The animals in Death Valley don't use technology to keep cool. They have special abilities that help them live there.

The kangaroo rat is one of the animals that live in Death Valley. During the day in Death Valley, it gets hotter than 100°F. The kangaroo rat rests all day in a hole in the ground. It covers the hole with grass to keep out the heat. The kangaroo rat comes out at night when it is cooler. This little rat is also very good at conserving(节约) water. It gets all the water it needs from the food it eats. Some kangaroo rats never take a drink of water in their whole lives.

The sun makes the desert sand very hot. Animals, like snakes, get too hot if they lie on the hot sand too long. One snake, called the sidewinder, can solve this problem. When it travels, the sidewinder bends its body into a “W” shape. Then it uses the bottom parts of the “W” like legs and walks sideways (向一侧). That way it touches only a little of the sand at a time, so the hot sand doesn't burn the snake. This strange way of moving is how the sidewinder got its name.

Most of water in the desert is too salty for most animals to drink. All water has some salt in it. As the desert heat dries up pools of water, the salt is left behind. The remaining water in these pools can be much saltier than those in the ocean. One kind of fish, the desert pupfish, can live in these salty pools because it can drink the salt water.
