Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves.
Some birds like eating locusts. but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you'll find the main use of colouring is protecting themselves. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree.
Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn't strong at all.From the passage we learn that locusts ___ .

I travel a lot, and I find out different "styles" (风格) of directions every time 1 ask "How can I get to the post office?"
Foreign tourists are often confused (困惑) in Japan because most streets there don't have names in Japan. People use landmarks (地标) in their directions instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop."
In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east, and then go another mile."
People in Los Angeles, California, have no idea of distance on the map; they measure distance in time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it's about five minutes from here." You say, "Yes, but how many miles away is it?" They don't know.
It's true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, 'Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." People in Yucatan believe that "I don't know" is impolite. They usually give an answer, often a wrong one.

Last month, students from one hundred and three universities in eighty-eight countries took part in an international computer programming contest, which took place in Harbin, China. Three-person teams from each school had five hours to solve eleven real world problems.
The students first listed the problems in order of difficulty. Then they figured out the requirements of each. They designed ways to test their solutions. And they wrote the needed software systems. Even the winning team from Shanghai Jiaotong University in China was not able to solve all the problems within the given limit. Stanford’s team solved five problems and finished in fourteenth place. Stanford was one of twenty-one American universities that took part in the contest this year.
The official name of the Battle of the Brains is the ACM International Collegiate Contest. The first final competition was held in 1977 at the Association for Computer Machinery Computer Science Conference. Today, a network of universities holds area competitions that send the winners to the world finals, now organized by IBM.
Contest spokesman Dong Heintzman says the world champions receive prizes and scholarships. They are also guaranteed an offer of employment or internship(实习) with IBM. He said, “We have had past world champions that IBM has gone and employed in our Zurich research laboratory and are now working on some of the leading edge materials in science and physics. We have a world finalist from China who’s been working on the Watson Supercomputer that in the near future will be playing Jeopardy(一种超级计算机名称)against the best Jeopardy players in the world.
