Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate (交际) with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars (毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special smell---a signal (信号) causing its neighbors to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn’t need to be in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar (花蜜) for honey. So why shouldn’t trees have ways of sending message?
1. It can be concluded from the passage that caterpillars do not feed on leaves that ______.
A.are lying on the ground | B.have an unpleasant taste |
C.bees don’t like | D.have an unfamiliar shape |
2.According to the passage, the willow tree was able to communicate with other trees by ______.
A.waving its branches | B.giving off a special smell |
C.dropping its leaves | D.changing the colour of its trunk |
3.According to this passage, bees communicate by ______.
A.making special movement | B.touching one another |
C.smelling one another | D.making unusual sound |

Tattoos (纹身) are becoming more and more common. But they are not a new thing. Scientists have found some frozen bodies from around 3,000 BC and their skin shows the marks of tattoos. For example, Otzi, the Iceman (the oldest body ever found), was discovered in the mountains of Austria. He had many different lines and crosses tattooed on his back and his knees.
The most common places to get tattoos are the tops of the arms for men and the bottoms of the backs for women. Any mark can be used but there are some common ideas. Some people like to get animals, like dragons, birds and tigers. Other people like to get something written in a foreign language, so Chinese and Japanese words are common in America and the UK. If you can’t read the language, make sure you get someone to check what they represent because the tattoo artist could write anything and you would never know.
It is a big decision to get a tattoo because they are very difficult to remove. It is possible with expensive laser surgery (激光手术) but this is very painful and amazingly expensive and the skin will never be perfect afterwards. You want to do a test, to see how you look with a tattoo, you can get a temporary tattoo which disappears after about a month. This kind is very popular in India, where people often have them for festivals.

In many places of Europe and America, most people don’t care very much whether you have a tattoo or not, though there are some types of job where they don’t like tattoos. But some Presidents of the USA have had them.

B. They help make people’s skin perfect.
