    【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】“Sticks and stones may break my bones, but words will never hurt me.”

    You probably heard those lines in grammar school, but do you really agree that harsh(严厉的) or negative words do not harm us? Words have power. Surely we all have had our feelings hurt by something someone said.

    We may not say words to hurt others, but the way we interpret (解释) them and how we say them may cause great harm. Here’s an example:

    An ancient king dreamed all his teeth had fallen out. He sent for a wise man to explain his dream to him: the dream means that all your relatives will die and you will be left alone! The king was very angry and threw the interpreter into prison. He then sent for another interpreter who said, “Congratulations! King! You will live many more years. In fact, you will survive all your relatives. Long Live the King!”

    Both interpreters gave the same interpretation, but there was a huge difference in the way they said it.

    Our speech must be understood by those who hear our words, but the way we say things and the intention behind them have as much power as the words themselves. Words can cause anger or appreciation. Which would you rather receive?

    People who say harsh and negative things may not mean to harm, but have you ever known anyone who is a naysayer? They often look at the dark sides of things. They always see the glass as half empty rather than half full. How do you feel when you are around this type of person? Remember: words have power. Use them wisely.

    【1】The author mentions the story of the ancient king to show that _____.

    A. one dream sometimes has different explanations

    B. good words can bring good luck to people

    C. people should be careful when talking to a king

    D. different ways of saying things have different effects

    【2】The underlined word naysayer in the last paragraph refers to a person who always _____.

    A. has a negative attitude

    B. likes to be praised

    C. talks big

    D. likes to repeat what others say

    【3】According to the text, how can people understand each other better?

    A. By sharing different life experiences

    B. By accepting different habits.

    C. By properly using words

    D. By recognizing different values.

    【4】The passage mainly talks about ______.

    A. the power of words

    B. the cruelty of the king

    C. how to understand others

    D. how to build good relationships

    【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 “______”.

    A. reach their normal level B. become confident

    C. walk with long steps D. get bored

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

    A. teachers will perform better with time passing

    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
