Before babies begin to produce words, they produce sounds. Some of these sounds will remain if they occur in the language being learned, and others will disappear. This is called the "babbling stage". A child does not learn the language "all at once". The child first speaks only one-word "sentences". After a few months, the two-word stage arises. During this stage, the child puts two words together. These two-word sentences have definite patterns and express grammatical and meaningful relationships. Still later, in the telegraphic stage, the child will produce longer sentences. These longer sentences are mainly made up of content words. The child's early grammar lacks many of the rules of the adult grammar, but gradually it will become perfect. All normal children everywhere learn language. This ability is not dependent on race, social class, geography, or even intelligence . This ability is uniquely for human. Question: This passage is mainly about _ . - differences between a child's language and an adult's - ways of teaching babies to talk - children's learning of the mother language - the importance of learning foreign languages
children's learning of the mother language

Kick around is an expression that is heard often in American English. A person who is kicked around is someone who is treated badly. Usually he is not really being kicked by somebody's foot. He is just not being treated with the respect that all of us want. A person who has kicked around for most of his life is someone who has spent his life moving from place to place. In this case, kicking around means moving often from one place to another. Kick around has another meaning when you use it with the word idea. When you kick around an idea, you are giving that idea some thought. There is no physical action when you kick a person upstairs, although the pain can be as strong .You kick a person upstairs by removing him from an important job and giving him a job that sounds more important, but really is not. Still another meaning of the word kick is to free oneself of a bad habit, such as smoking cigarettes. Health campaigns urge smokers to kick the habit. Question: What does the idiom "kick over the traces" in "All kids seem to want to kick over the traces and do what they like to" means _ . - disobey the commands - obey the traditions - ride a horse or mule - punish animals strictly
