But plants can protect themselves in both physical and chemical ways.Some plants have their own ways to keep animals away. For example ,
26、 the leaves of the holly(冬青)have sharp prickles(刺)that discourage gra ss eating animals. Holly leaves on lower places have more prickles than leaves on upper places. This is because the lower leaves are easier for most animals to reach. Some plants, such as the oak trees腮树),have thick and hard leave
27、s that are difficult for animals to eat. Some grasses may contain asandy material, and eating such grasses wears down the animals teeth. Many plants also have chemical defenses. Some plants produce chemicals that taste bitter(苦)or cause an unpleasant reaction. Some plants may fight against an attack
28、 by increasing the production of these chemicals. When a worm bites a tobacco leaf (烟叶), the leaf produces a chemical smell. Many plants depend on both physical and chemical defenses. A certain plant in China , for instance , has prickly leaves , and each prickle has poisonous water(毒液). Only one ex

And the scientists who discovered it want to speed up the proof discovering the chemical secrets behind the natural degradation

43、To check people for cancer, doctors must collect tissue from a patient tum or (肿瘤)and test it. This process can take a long time. But in December, scientists from the University of Queensland in Australia developed a simple cancer test that can detect ( 检测)cancer in a patient s bloo The test takes l
44、ess than 10 minutes. The test is about 90 percenaccurate, the Guardian reported.With all of these treatments, cancer can be effectively controlled. Honjo believes most kinds of cancer will become treatable by 2050.“ Even if we cannot completely elimnae the tumor, we can survive while still having pa

The study finds that .A. different penguins have their own favorite fishB. penguins have different genomes for the fivetastesC. penguins don t have any of the)av tastesD. penguins can t taste the flavor of fish(八)In recent history, there have been some amazing inventions which
56、 have changed our lives.The plane has made international travel faster and easier. The Internet has brought people closer. And you must know the names of some famous inventors like Henry Ford and Steve Jobs. But there are many everyday objects which you probably don and you don t know who invented t
57、hem. Take for example Nils Bohlin, who inventee modern-day car seat belt &全 带).Before 1959, only two -point seat belts were available, and the only people who often wore them were race car drivers. The two- point seat belt couldn t protect passengers from internal injufiesduring serious car accident
58、s.In 1958, Bohlin joined V olvo Car Corporation as a safety engineer. He came up with the three-point seat belt to keep passengers from flying out of their cars during collisions The three-point seat belt used one strap 带子)across the chest (胸部)and another across the legs and then the two joined at the same place. Amazingly, this was a very s
