听力原文: "Sesame Street" has been called "the longest street in the world". That is because the TV program by that name can be seen in so many parts of the world. The program started in New York in 1969. In the United States, more than six million children watch the pro gram regularly. Parents praise it highly. Many teachers consider it a great help. Tests have shown that children from different backgrounds have benefited from watching "Sesame Street". Those who watch it five times a week learn mom than the occasional viewers. In the United States the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.
In its American form, "Sesame Street" is shown in nearly fifty countries. Three foreign shows based on "Sesame Street" have also appeared: In Spanish, Portuguese, and German.
The program uses songs, stories, jokes and pictures to give children a basic understanding of numbers, letters and human relations.
Why has "Sesame Street" been so much more successful than the other children's show? Many reasons have been suggested: the education al theories of its creators, the skillful use of a variety of TV tricks, the famous stars on "Sesame Street", etc. But the best reason for its success may be that it makes every child watching it feel able to learn. The child finds himself learning, and he wants to learn more.

听力原文:S: I'm sorry. I just don't agree with you at all.
P: Look. Take the example of an international student applying for university admission. If the student has a 500 on the TOEFL or an 80 on the Michigan Test, most admissions officers will accept the applicant. The student with a 499 or 79 won't be considered. The officer won't even look at transcripts.
S: Right. But I think that proves my point, not yours.
P: How?
S: Well, it's the admissions officer who decides how to use tile test. The TOEFL and the Michigan are good English proficiency tests, but that's all they are. And English proficiency is necessary for success in an American university, but so are several other factors, including good academic preparation.
P: Good academic preparation is more important.
S: Maybe. I don't really know. But what I'm trying to explain to you is that admissions officers should use the proficiency test as one of many considerations, and as such, they really shouldn't insist on a rigid cut - off score like 500 or 80.
A: Isn't this the basic disagreement that Paul thinks the tests are bad in themselves, and Sally believes that the tests are good, but that many people don't use them for their intended purpose.
P. I don' t agree with having the tests, Professor Ayers, and that's my position.
S: But Paul, what would you do to evaluate the English proficiency of a student ten thousand miles away without a standardized test?
P: I admit that's a big problem.
S: It sure is.
A: Okay, class, For Wednesday, let's consider the problem of evaluation without standardized tests like the TOEFL, the SAT, GMAT, and GRE. Paul says that there ought to be alternative. Sally doesn't seem to believe that there is an appropriate alternative. Please bring in your ideas and suggestions, and we'll discuss them.
