If people meet them, they will come down in great quantities to bite and kill, sucking blood and flesh through the wounds they cause.In June, 1966, a boy named Marl Andre who went into the mountains in search of butterfly specimens (标本) was killed by these butterflies. A country boy saw him as he was just about to raise his net to catch a butterfly. Suddenly thousands of butterflies came down upon him, covering him all over. The boy struggled and cried as he tried to free himself from their attack. Finally he fell senseless to the ground. Police examined his body and proved that he had died of bites by butterflies.In New Guinea, there is a kind of needlefish(腭针鱼)which also kills men. Needlefish likes light. At night, it will swim near the lights of fishing boats, then suddenly shoot out of water like an arrow to its target, and force its 3-inch sharp mouth into a human body. Often people are thrust in the eye, or through the chest or stomach, resulting in death. Sometimes it will evenattack the people in a fishing boat in the day.About 10 persons in the world are killed by sharks every year, yet more than 20 are killed by needlefish every month.( )36.

Deaths Caused by Butterflies and NeedlefishCChina is a nation with a rich culture in handwriting. “Even though the computer is widely used today, Chinese people should not forget the skill of writing with hands,” said a Chinese government official.Nowadays, the computer has become a very useful tool to help people to write. As people use computers more often than before, many people have forgotten how to write Chinese characters (字). People often make a lot of mistakes in writing.At present, China is trying to help pupils and teachers to improve their writing with the help of information technology. With the technology, it is hoped that teachers can write their questions on the blackboard and students can respond by writing, too.The Chinese character test shows that nowadays, many college students’handwriting has become worse. Many college students do not know how to compose (组成) words or sentences in Chinese character in the right way. Not only kids, many adults also have met the same problem. They might be able to tell the general form of a certain character. However, if you ask them to spell out the character in detail (详细地), they can’t. On the other hand, they can easily type out the character on a computer.In the national language teaching course, we can solve this problem with the use of certain technologies. Actually, apart from(除了)technology, there is a lot that we can do. For example, we may ask students to finish their homework by writing with hands instead of typing.( )41. People often make a lot of mistakes in writing Chinese characters because ________.A. they use computers too often and many people have forgotten how to write themB.

Don’t forget our mother language.DOne mother took many lovely photos of her sleeping son. After the little baby, Wen, fell asleep, his mother would create an imaginary fairy tale scene behind him and then take those lovely photos.When the baby was asleep, he was photographed traveling to castles in the clouds, cooking eggs in the kitchen or swinging on the swing with an elephant to catch him. The photos have attracted people around the world because of the cute creativity.Mrs Liao drew inspiration(灵感) from a famous child photographer Anne and a mother Adele who published a book of similar photos, so she decided to turn her hobby of photographing toward her son. She said, “Every day just before Wen’s nap, I would imagine him being the main character in one of my favorite scenes and paint a background setting with common clothes, lovely animals and other household materials, just like how an artist would deal with the paint brush. After he fell asleep, I would place him at the centre of the theme I had creates and start taking photos.”With a collection of more than one hundred photos of Wen, Mrs Liao published a book in Chinese in Taiwan. And there are plans for an English version to be published. She told her fans, “I’m truly touched by your support.”( )46.
