M: Come to think of it, how much are lessons？ I presume you can get those here, too.
W: You bet. (23) It's 125 dollars a day for one to one instruction, 3 hours in the morning, and 3 in the afternoon. Personally, I'd recommend learning as part of a group, though. It's more fun, and it's quite a bit cheaper. It depends on what you prefer. That's 76 dollars per person, for the same number of hours as individual instruction.
M: That's a good deal. Does that include equipment hire？
W: Well, since you're our first customer of the season, we might just throw that in.
M: Fantastic. We'll definitely see you next week. Oh, one more thing. Is off-peak season still until the end of November？
W: Yes, and then for the whole of March. Oh, hang on. No, the seasons have changed a bit. I can't believe I forgot. The centre is closed from the beginning of April to the end of September. Off-peak's from the 1st October until the 10th December, and then peak season is around Christmas and New Year. Post Christmas off-peak season is also the whole of February and March.
M: Yeah. (24) So peak season is from the 11th December until...？
W: (24) From the 11th December until the 31st January. Lots of school groups in January, even though it's 50% more expensive than off-peak season.
M: (25) So we're getting a good deal by turning up at the start of the season.
W: Definitely. It's a good idea anyway—word hasn't really got around that everything's up and running, and most people are at work, so you get the slopes pretty much to yourself.

听力原文： All warm-blooded animals are very helpless at first. Young birds and young bats must be taught to fly. Thousands of young seals drown every year. They never learn to swim "naturally." The mother has to take them out under her flipper and show them how. Birds sing without instruction; however, they do not sing well unless they are able to hear older members of their species. Older harvest mice build better nests than beginners. Frank Buck says that the young elephant does not seem to know at first what his trunk is for. It gets in his way and seems more of a hindrance than a help until his parents show him what to do with it. Insects, seem to start life equipped with all necessary reflexes, but they seem to improve their talents with practice. Young spiders, for example, begin by making quite primitive little webs. They attain perfection in their art only after much time. Older spiders, if deprived of their spinnerets, will take to hunting.

A．They know what to do because of instinct.
B．They know how to fly naturally.
C．They often reject their parents.
D．They learn behavior. from their parents or other animals.

How useful are the views of public school students about their teachers？
Quite useful, according to preliminary results released on Friday from a research project that is intended to find new ways of distinguishing good teachers from bad.
Teachers whose students described them as skillful at maintaining classroom order, at focusing their instruction and at helping their charges learn from their mistakes are often the same teachers whose students learn the most in the course of a year, as measured by gains on standardized test scores, according to a progress report on the research.
Financed by the Bill and Melinda Gates Foundation, the two-year project involves scores of social scientists and some 3,000 teachers and their students in districts such as New York and Pittsburgh.
Statisticians began the effort last year by ranking all the teachers using a statistical method known as value-added modeling, which calculates how much each teacher has helped students learn based on changes in test scores from year to year.
Thousands of students have filled out confidential questionnaires(秘密调查问卷)about the learning environment that their teachers create. After comparing the students ratings with teachers value-added scores, researchers have concluded that there is quite a bit of agreement.
Classrooms where a majority of students said they agreed with the statement, "Our class stays busy and doesnt waste time," tended to be led by teachers with high value-added scores, the report said.
The same was true for teachers whose students agreed with the statement, "In this class, we learn to correct our mistakes."
Few of the nations 15,000 public school districts systematically question students about their classroom experiences, in contrast to American colleges, many of which collect annual student evaluations to improve instruction, Dr Ferguson said.
Until recently, teacher evaluations were little more than a formality(形式)in most school systems, with the vast majority of instructors getting top ratings, often based on a principals superficial impressions.
But now some 20 states are overhauling their evaluation systems, and many policymakers have been asking the Gates Foundation for suggestions on what measures of teacher effectiveness to use, said Vicki L. Phillips, a director of education at the foundation.
One notable early finding, Ms Phillips said, is that teachers who incessantly(不停地)drill their students to prepare for standardised tests tend to have lower value-added learning gains than those who simply work their way methodically through the key concepts of literacy and mathematics.
What is said about teachers rated as good at keeping their classes in order？
A．Their students gain more in test scores.
B．Their classes stay busy and don"t waste time.
C．Their students learn fastest during a semester.
D．They help students learn to correct their mistakes.

Winged Robot Learns to Fly
Learning how to fly took nature millions of years of trial and error --but a winged robot has cracked it in only a few hours, using the same evolutionary principles.
Krister Wolff and Peter Nordin of Chalmers University of Technology (CUT) in Gothenburg, Sweden, built a winged robot and set about testing whether it could learn to fly by itself, without any pre-programmed data on what flapping is or how to do it.
To begin with, the robot just twitched and jerked erratically. But, gradually, it made movements that gained height. At first, it cheated -- simply standing on its wing tips was one early short cut. After three hours, however, the robot abandoned such methods in favor of a more effective flapping technique, where it rotated its wings through 90 degrees and raised them before twisting them back to the horizontal and pushing down.
"This tells us that this kind of evolution is capable of coming up with flying motion," says Peter Bentley, who works on evolutionary computing at University College London. But while the robot had worked out how best to produce lift, it was not about to take off. "There's only so much that evolution can do," Bentley says. "This thing is never going to fly because the motors will never have the strength to do it," he says.
The robot had metre-long wings made from balsa wood and covered with a light plastic film. Small motors on the robot let it move its wings forwards or backwards, up or down or twist them in either direction.
The team attached the robot to two vertical rods, so it could slide up and down. At the start of a test, the robot was suspended by an elastic band. A movement detector measured how much lift, if any, the robot produced for any given movement. A computer program fed the robot random instructions, at the rate of 20 per second, to test its flapping abilities. Each instruction told the robot either to do nothing or to move the wings slightly in the various directions.
Feedback from the movement detector let the program work out which sets of instructions were best at producing lift. The most successful ones were paired up and "offspring" sets of instructions were generated by swapping instructions randomly between successful pairs. These next-generation instructions were then sent to the robot and evaluated before breeding a new generation, and the process was repeated.
Which of the following is NOT true of what is mentioned about the winged robot in the second paragraph？
A．The two professors of CUT built the winged robot.
B．The two professors of CUT tested whether the winged robot could learn to fly.
C．The two professors of CUT programmed the data on how the robot flapped its wings.
D．The two professors of CUT tried to find out if the robot could fly by itself.

So much is certain: that we would have doctors and preachers, lawyers and defendants, marriages and births—but our spiritual outlook would be different. We would lay less stress on "facts and figures" and more on a good memory, on applied psychology, and the capacity of a man is to get along with his fellow-citizens. If our educational system were fashioned after its bookless past we would have the most democratic form. of "college" imaginable. Among tribal people all knowledge inherited by tradition is shared by all; it is taught to every member of the tribe so that in this respect every- body is equipped for life.
It is the ideal condition of the "equal start" which only our most progressive forms of modern education try to regain. In primitive cultures the obligation to seek and to receive the traditional instruction is binding to all. There are no "illiterates"—if the term can be applied to peoples without a script—while our own compulsory school attendance became law in Germany in 1642, in France in 1806, and in England in 1876, and is still non-existent in a number of "civilized" nations. This shows how long it was before we deemed it necessary to make sure that all our children could share in the knowledge accumulated by the "happy few" during the past centuries.
Education in the wilderness is not a matter of monetary means. All are entitled to an equal start. There is none of the hurry, which, in our society, often hampers the full development of a growing personality. There, a child grows up under the ever-present attention of his parents' and therefore the jungles and the savannahs know of no "juvenile delinquency". No necessity of making a living away from home results in neglect of children, and no father is confronted with his inability to "buy" an education for his child.
Why do modern states invest in institutions of learning？
A．To get a repayment for what an individual's education has cost.
B．To get rewards for what they have spent.
C．To charge interest.
D．To give all the children free education.
