Not long ago, people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life. Scientists note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other human beings. One study shows that babies can learn before they are born. The researchers placed a tape recorder on the stomach of a pregnant woman. Then, they played a recording of a short story.  On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placing a device in the mouth of the newborn baby. The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way, he would hear a different story. The researchers say the baby clearly liked the story he heard before he was born. They say the baby would move his mouth so he could hear the story again and again. Another study shows how mothers can strongly influence social development and language skills in their children. Researchers studied the children from the age of one month to three years. The researchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children's activities and did not interfere unnecessarily. They tested the children for thinking and language development when they were three years old. Also, the researchers observed the women for signs of depression. The children of depressed women did not do as well in tests as the children of women who did not suffer from depression. The children of depressed women did poorly in tests of language skills and understanding what they hear. These children also were less cooperative and had more problems dealing with other... According to the passage, which of the following is NOT the factor that influences intelligence development in babies? A) The environment. B) Mother's sensitivity. C) Their peers D) Education before birth.

Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming , that periodically killed themselves together, and no one knows just why! The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life. However, when the lemmings' food supply becomes too low to support the population, a _ migration begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea. The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown. A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening. The passage is mainly about  _  . A) how lemmings find food B) why animals kill themselves C) the lemmings' self-killing D) the food supply in the Scandinavian mountains

The Post Office in Britain is famous for getting letters and parcels to places to which they should be sent. The problem is that we the public have to observe the rules. For example, we must put a stamp on a letter. If we don't, the receiver will have to pay double. We often see the sign ALL LETTERS MUST BE CORRECTLY ADDRESSED. These days, this means having to use postcodes. If you didn't use a postcode, it's no good complaining that your letter should have arrived sooner. Parcels are a problem because they must be correctly packaged. If Aunt Sophie is going to send you a jar of your favorite jam, she will have to wrap it up well. The most important thing we have to do is to address our letters and parcels legibly  and correctly. This means clear handwriting and correct spelling. What we should do and what we actually do are often miles apart. Recently, the Post Office had to deliver a letter which showed a name followed by the word Arijaba. What is this, do you think? Arabic? Hiodustani ? Wrong both times! Say it out loud and you'll see it's just plain English. HARWICH HARBOUR! From the passage we can see that postmen   _  . A) have no difficulty in delivering any letters B) have difficulty in delivering mis-spelt letters C) won't deliver any letters with bad handwriting D) can deliver all letters to their destinations
