　　What makes a child speak a language has long been a puzzle to linguists. 61 speaking, there are two schools of linguists, both of whom try to explain 62 a child picks up a language so easily. The fact that a child picks a language 63 is 64 : At one year old, a child is able to say “bye-bye”; at two, he is able to use fifty; by there he begins to 65 tenses. The famous American linguist Noam Chomsky 66 that human being have a sort of built-in system for language use, and that the 67 is 68 . Children are not taught language 69 they are taught arithmetic. Other linguists, 70 , hold the view that a child learns 71 of his language from the hints in the environment. 72 , theorists of both schools 73 that there is a biological basis for language use. The 74 is which is more important, the inner ability or the environment. This is certainly a field 75 to be explored. Researchers from both schools are busy finding evidence to 76 their own theory, but 77 side is persuading the other.

　　It seems that in order to 78 why a child learns a language so easily, we have to 79 the joint efforts of both schools. Some linguist, like De Villiers, has recognized the value of cooperation, and 80 linguists of both sides to work together.

　　Many people have difficulty in studying mathematics. Sometimes their difficulty 61 from the psychological idea that they are “not good 62 math”. It has been demonstrated many times that it is often this idea 63 is causing their problems 64 than any lack of skill in mathematics. The 65 way to deal with this problem is to 66 yourself that math involves using the same number you have been using the same numbers you have been using 67 your life and that you know them as well as 68 else. Then set your mind to learning how they used in the 69 part of mathematics you are studying.

　　Another problem many people 70 is that in mathematics, unlike some other 71 you may have studied, the material has a very important 72 or order. If you don’t understand a 73 of a mathematics text, it is no 74 going on to the next section. Many sections of math books are 75 on information presented earlier, so it is 76 that you understand a section before going on to the next.

　　Sometimes students in mathematics courses do not read the written material in the text 77 assume that the teacher will tell them 78 they need to know. This can cause them 79 problem, since many teachers assume that students have read the text before coming to class. The written sections of mathematic textbooks 80 much valuable information.
