3、 Monday中国科学家研发出"鸡肉米"和"猪肉米"
Chinese researchers have made a small but important step for the future of food. They have developed"chicken rice" and"pork rice", which are new dishes that mix cell-cultured meat and common grains.
The China Meat Food Comprehensive Research Center and the Beijing Academy of Food Sciences led this breakthrough. They grow chicken and pork cells directly on rice and other plants.
Professor Wang, the main scientist of this project, said, "These dishes look like normal rice——white, brown or purple. But when cooked, they smell like both rice and meat. " Not only do these dishes taste good, but they also have good nutrition. Wang said, "We can control exactly how much protein, amino acids, fiber, carbs and other nutrients are in them. This means we can make these foods for special eating needs. "
The big innovation is using rice as a"small carrier". Before, making cell-cultured meat needed expensive and artificial carriers. Wang said, "These carriers often cause problems with food safety and make production more expensive. But rice is a natural and safe choice. It has a lot of fiber and good nutrients. "
To make these dishes, they treat the rice first to make a good place for the cells to grow. For example, "pork rice" is made by growing different groups of pork muscle and fat cells on changed rice grains. Then they put them together.
Professor Zhou from Jiangnan University thinks this is a big step forward. He said, "Chicken rice and pork rice are new in cell-cultured meat research. China can be a leader in this area. " The research team is hopeful to make a lot of these in the near future.
Fitness coach Yao likes the idea. He said, "High protein, high fiber and healthy carbs. That's great for me. The price matters, but I will try it. " But Yao knows that people need to accept it. He said, "It's a new thing. People will be interested but careful. It will take time for these‘grown' dishes to be popular. "

4、 阅读短文,根据要求完成下面小题。
Do you yawn(打哈欠)? There are about 20 reasons that scientists think are possible for yawning after research. They do not know exactly why yawning happens, but they do know many facts about yawning.
We know that everyone yawns in the same way. First you open your mouth slowly. Your mouth stays open for about five seconds. You take in a lot of air and then push it out. Then you quickly close your mouth. We also know that yawning is contagious; when you see someone yawn, you yawn, too.
Many people say they yawn because they are bored or tired. That might be true. People do often yawn before they sleep and after they wake up. However, we know that people also yawn when they are excited or nervous. Olympic runners, for example, often yawn before a race. Why is that? In 2007, scientists found that a yawn can help a warm brain cool down.
Some scientists believe that yawning makes you notice things more quickly. When you yawn, you breathe deeply. You also stretch(拉长) the muscles in your face, mouth, and neck. Your eardrums stretch, too. Maybe this helps you to be quicker to notice things.
In some countries, people think yawning is not nice. People put their hands over their mouths to cover a yawn. In other countries, people think yawning is healthy. They think that opening the mouth very big can let good things in. When they breathe out, they think that bad things go out of the body with the air.
Scientists do not spend much time studying yawning. That is probably because yawning does not hurt. It is just something we do.
(1)、How many reasons that scientists think are possible for yawning after research? (no more than 4 words)(2)、Why do Olympic runners often yawn before a race? (no more than 10 words)(3)、What can be stretched when you yawn? (no more than 12 words)(4)、请将文中画线的句子翻译成汉语。(5)、请给短文拟一个适当的英文标题。 -
