It is, everyone agrees, a huge task that the child performs when he learns to speak, and the fact that he does so in so short a period of time challenges explanation.
Language learning begins with listening. Individual children vary greatly in the amount of listening they do before they start speaking, and late starters are often long listeners. Most children will "obey" spoken instructions sometime before they can speak, though the world "obey" is hardly exact as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gesture and by making questioning noises.
Any attempt to discover the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during .the first few months one or two noises sort themselves out as particularly indicative of (表示) delight, suffering and so on. But since these cannot be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new sounds to their sound collection. This self-imitation (模仿) leads on to deliberate (深思熟虑的) imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.
By saying "the fact... challenges explanation", the author means that ______.

Task 2
Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
Exercise should play a very large role in our daily life. Everyone, no matter what age, needs exercise every day. However, modem life may prevent people from getting the daily exercise they need.
There are many kinds of exercises that help people keep physically(身体上地) fit, if they axe done every day. There are sit-up(仰卧起坐) exercises that anyone can perform. for a few minutes every day. For a young person football is one of the best games. If more people would exercise daily, they would find themselves better all the time.
Television and other modem inventions could possibly be a factor that produces physical unfitness(不适). Television can be very educational, but mostly it is just a waste of time: With the automobile(汽车), another modem invention, people no longer walk to any place. If people are going to sit for hours in front of their TV sets and ride in their cars everywhere, they need to get exercise by sit-ups or playing football.
