【题目】An old friend from California called from the airport to tell me that he had arrived. I was not able to leave the office, but I had made plans for his arrival. After explaining where my new house was, I told him that I had left the key under the doormat (门垫). Since I knew it would be pretty late before I could get home, I suggested that he make himself at home and help himself to anything that was in the refrigerator.

Two hours later my friend phoned me from the house. At the moment, he said, he was listening to some of my records after having had a delicious meal. Now, he said, he was drinking a glass of orange juice. When I asked him if he had had any difficulty finding the house, he answered that the only problem was that he had not been able to find the key under the doormat, but luckily, the living room window by the apple tree had been left open and he had climbed in through the window. I listened to all this in great surprise. There is no apple tree outside my window, but there is one by the living room window of my next door neighbor's house!

【题目】In the summer of 1978 an English farmer was driving his tractor through a field of wheat when he discovered that some of his wheat was lying flat on the ground. The flattened wheat formed a circle about six meters across. Around this circle were four smaller circles of flattened wheat. The five circles were in a formation like five dots. During the following years, farmers in England found the strange circles in their fields more and more often.

The circles are called “crop circles” because they appear in the fields of grain ― usually wheat or corn. The grain in the circles lies flat on the ground but is never broken; it continues to grow, and farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September.

At first, people thought that the circles were a hoax. Probably young people were making them as a joke, or farmers were making them to attract tourists. To prove that the circles were a hoax, people tried to make circles exactly like the ones that farmers had found. They couldn’t do it. They couldn’t enter a field of grain without leaving tracks, and they couldn’t flatten the grain without breaking it.

Many people believe that beings from outer space are making the circles to communicate with us from far away and that the crop circles are messages from them.

Scientists who have studied the crop circles suggested several possibilities. Some scientists say that a downward rush of wind leads to the formation of the circles — the same downward lash of air that sometimes causes an airplane to crash. Other scientists say that forces within the earth cause the circles to appear. There is one problem with all these scientific explanations: crop circles often appear in formations, like the five-dot formation. It is hard to believe that any natural force could form those.

【题目】But what is teacher quality? How can one measure it reliably?

An analysis is issued on a sample of data from a Texas school district. Experts argue convincingly that teacher effectiveness should be measured by students’ gains on standardized tests: Mr. Smith is probably a better teacher than Ms. Brown if his students consistently improve their test scores more than hers do.

Though this approach is appealing, there are tricky issues. For example, what if Ms. Brown teaches in a school where students score so high there is little room for improvement?

The authors try to correct for this problem, as well as other sorts of measurement issues, to generate a measurement of teacher effectiveness. The paper is primarily concerned with how this measure is related to other observable characteristics.

The first finding is that there is a large variation in teacher effectiveness: some teachers consistently have a larger impact on their students’ achievement than others.

Second, easily observable characteristics like having a master’s degree or a passing score on the teacher certification exam are not correlated关联 with teacher effectiveness.

Then what does matter? The most important single influence is experience: first-year teachers are much less effective than others. The second year is significantly better, and by the fourth year, most teachers hit their stride.

It is not entirely clear whether this experience effect is learning by doing (the more you teach, the more effective you become) or survival of the fittest (those who are not good at teaching tend to drop out early.)

From my reading of the paper, both effects appear important and there is no simple answer. The data do suggest, however, that teacher effectiveness is pretty clear by the end of the second year, so the information to make an informed decision is available at that time.

The authors also investigate the contentious 有争议的issue of racial matching of students and teachers. Here they find strong evidence that minority teachers tend to be more effective with minority students. Again, it is unclear whether this is because of a role model effect (students respond better to a teacher of their own race) or an empathy effect 移情效应(teachers empathize better with students of their own race) or something else entirely.

The authors also look at teacher mobility. There is some evidence that teachers who quit teaching or switch schools tend to be below average in effectiveness. This is consistent with the survival-of-the-fittest model.

【1】The schoolmaster could decide wisely whether to further employ the teacher by the end of the ______.

A. the first year B. the second year

C. the third year D. the fourth year

【2】The phrase “hit their stride” most probably means “______”.

【3】The author of this passage holds the view that ______.

B. ineffective teachers should leave earlier rather than later

C. teacher’s effectiveness is apparent after a couple of years

D. a master’s degree will improve teacher’s effectiveness

【4】Why do black teachers tend to be more effective with black students?

A. Students fell secure, so they respond better.

B. Teachers sympathize with students of their own race.

C. There are entirely some other identified reasons.

D. The reasons are far from clear and definite.

【5】Which of the following may serve as the best title?

A. The Quality of Teaching

B. Impact of Teacher Quality on Student Learning

C. Different Sorts of Measurement Issues

D. Survival-of-the-fittest Model vs. Learning-by-doing Model
