Some universities have reportedly canceled the men' s 5,000-meter race and the women' s 3,000-meter race in their sports meetings due to worries that the students couldn't cope with the race. Students' physical conditions are worrying in the nation.

In ancient China, Confucian culture stressed the values of knowledge and morality and considered people with physical strength uncivilized. Having a strong body was the most obvious distinction between manual workers and civilized intellectuals.

In today's China, knowledge, which is regarded as the source of productivity, is more highly valued than physical strength. Parents and teachers value clever heads over strong bodies.

The physical condition of Chinese people has improved a lot since China's reform and opening-up policy in the early 1980s,as nutrition and food are no longer a problem for most people.

Chinese people should develop the habit of sports exercise starting from childhood. The government and education authorities must create more conditions for the people, especially for students, to do sports regularly.

A healthy and strong body is a basic guarantee for a healthy life. The health of the whole nation will also have an impact on China's future development.

Plants are living things. So can they feel pain? Plants don't feel pain the same way animals and people do, says Anke Steppuhn. She is a scientist at the Free University of Berlin in Germany. “What we define as pain usually has to do with a nervous system，” Steppuhn explains. When you put your hand too close to a hot stove, nerve cells send a signal to your brain. Your brain decodes(解码) that signal as pain. This causes you to pull your hand away before any serious damage is done.

Plants don't have nerves or brains, so they can't feel pain like we do. “But plants do recognize when something is hurting them，” Steppuhn says. Because they are rooted to the ground, they can't escape a dangerous situation. So they need other ways of fighting back.

The biggest threat to a plant's life is getting eaten. Some plants grow sharp little hairs. Other plants produce bad－tasting or even harmful chemicals. These force an attacker to abandon its meal. A plant called bittersweet nightshade does something even smarter, Steppuhn found. When a slug(蛞蝓) chews holes in a nightshade' s leaf, liquid begins dripping(滴) around the wound. It is almost as if the plant were bleeding. The liquid is sugary nectar(花蜜), and it happens to be a favorite food of ants. In their effort to collect the nectar, the ants swarm(蜂拥而至) all over the injured plant. They will attack anything that stands in their way. That includes the slug that damaged the plant in the first place. It's a very clever trick. Whenever a slug attacks a plant, the plant calls an army of ants to kill the slug.

Nectar isn't the only way plants attract bodyguards. They also release certain chemicals into the air when they are being eaten. People usually can't detect these smells. But wasps(黄蜂) can. When a wasp detects this cry for help, it races to the scene of the crime. If it finds the right kind of insect chewing down on the plant, the wasp will interrupt the attacker's meal. It will do this by laying eggs inside the insect’s body!

Plants are boring. They just sit there photosynthesizing （光合作用） while animals have all the fun. Right? Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plant co-evolution （协同进化） started with ants feeding on plants and plants evolving ant-friendly features.

Plants make a number of different structures that are specific for ant use. Some plants have evolved features that persuade ants into defending them from attack from other insects and even mаmmаlѕ. Тhеѕе іnсludе hollow thorns that аntѕ will live іnѕіdе, or ехtra nесtаr (琼浆) оn lеаvеѕ or stems for the ants to eat. Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around, by providing them with rich food packets attached to the seeds. The ant will pick up the seed and carry it away, eat the food packet, and leave the seed - often in a nutrient-rich area where it'll grow better, and since it's farther away from its parent, they won't have to compete for resources.

But scientists weren't sure how the evolutionary relationship between ants and plants got started. If evolution is an arms race between species developing ways to make use of their neighbors, then scientists wanted to know whether plants or ants fired the first shot. It was a chicken-and-egg question, whether things started with ants developing behaviors to take advantage of plants, or plants evolving structures to take advantage of ants.

The history of ants and plants evolving together goes back to the time of the dinosaurs, and it's not easy to tell from fossils who fired the first shot. However, it is a question of little significance. Scientists say their study maters because it provides a look at how these widespread and complex interactions evolved.

A.reward the ants B.make a fool of ants

3.Which is true about the evolutionary relationship between ants and plants?

A.Ants depended more upon plants. B.It caused a race for better evolution.

C.How it got started was uncertain. D.It was of little value for future studies.

4.What's the author’s purpose of writing the passage?
