Yuan Longping, a great scientist, is the first person to develop a kind of hybrid rice(杂交水稻)which helps fight hunger in China.
Food was a big problem in China in the past. This was because China had 22 percent of the world’s population, but only 7 percent of its farmland. In the 1960s, China suffered(遭受)serious hunger. Millions of people died because they had no food. As an agronomy(农学)teacher, Yuan was very sad to see this. “How can I help them have enough food?” he thought. He decided to work on a kind of hybrid rice. It has a high output(产量).
At that time, other scientists didn’t think hybrid rice was worth studying. But Yuan and his team worked on it every day. They took very good care of their rice seeds.
At last, in 1973, they grew a new kind of hybrid rice. This rice is strong. Farmers can grow it in many different kinds of farmland and also in bad weather. It can also fight disease. Its output was much greater than common kinds of rice. With the new kind, about 70,000,000 people could have food every year!
Yuan solved the food problem in China. But he is still working on rice. Before he retires, he hopes to grow rice in the sea!

A robot needs to be able to move around its environment. It can move on wheels (轮子), walk on legs or be driven by small engines (发动机). A robot can move either the whole body or just parts of it.
A robot needs to be able to make itself work. Some robots might make it with sunlight, some might with electricity (电).
A robot needs some kind of “smarts”. A programmer is the person who gives the robot its “smarts”. The robot will have to have a certain way to get the program so that it knows what it is and what to do.

【推荐3】Have you ever wondered why birds sing? Maybe you thought that they were just happy.
After all, you probably sing when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims (声称) as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting (筑巢) season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.
1. Some scientists believe that most of the time bird’s singing is actually ________.A.an expression of happiness | B.a way of warning |
C.an expression of anger | D.a way of greeting |
A.A place where families of other species are not accepted. |
B.A place where a bird may shout at the top of its voice. |
C.An area for which birds fight against each other. |
D.An area which a bird considers to be its own. |
A.Because they want to invite more friends. | B.Because their singing helps frighten outsiders away. |
C.Because they want to find outsiders around. | D.Because they want to express their happiness. |
【推荐1】It was a dark evening in 1999. Song Yang, a 19-year-old student, lost his way in west London. This was only his third day in the UK. He saw an old man carrying heavy bags on the side of the road, unable to move. Song helped him home. The old man, named Hans, was born in Switzerland. He lived by the River Thames alone(单独). Although the view was amazing through the window of his house, it was a mess inside.

Hans often helped Song learn English and get to know the country. Song helped make meals and do the housework. Soon the two became friends and family. Each time Song came back to China, he would take Hans with him.
In 2007, when Song completed(完成) his studies in the UK and returned to China, Hans had to stay in London by himself. After a few months of living without Song, Hans got very sick(生病).
