【題目】Sure，it's good to get along with your teacher because it makes the time you spend in the classroom more pleasant．

And yes，it's good to get along with your teacher because，in general，it's smart to learn how to understand the different types of people you'll meet throughout your life．

"But really，there's one super﹣important reason why you should get along with your teacher．When you do，learning bursts right open，"says Evelyn Vko，a longtime teacher who writes an education column called"Teacher Says"for the Washington Post newspaper．

In fact，kids who get along with their teachers not only learn more，but they're more comfortable asking questions and getting extra help．This makes it easier to understand new material and do your best on tests．When you have this kind of relationship with a teacher，he or she can be someone to turn to with problems，such as problems with learning or school life，such as bullying．

As a kid in a primary or middle school，you're at a wonderful stage in your life．You're like a sponge （海綿），able to absorb lots of new and exciting information．On top of that，you're able to think about all this information in new ways．Your teacher knows that，in most cases，is very excited to be the person who's giving you all that material and helping you make it．Remember，teachers are people，too，and they feel great if you're open to what they're teaching you．That's why they wanted to be teachers in the first place﹣to teach!

Some kids may be able to learn in any situation，whether they like the teacher or not．But most kids are sensitive to the way they get along with the teacher，and if things aren't going well，they won't learn as well and won't enjoy being in class．

【1】In the passage，the author mainly talks about ．

A. how to get along well with others

B. how much the students are expected of to get along with teachers

C. the importance of a good relation with teachers

D. how to make the time in the classroom more pleasant

【2】"Learning bursts right open"in the third paragraph really means ．

A. there will be more problems with learning

B. you find an opening to learning

C. learning becomes easier for you at once

D. there will be no problems at all with learning

【3】Which of the comments is FALSE on teachers and their work according to the passage？

A. Teachers sometimes have the same feelings as students do．

B. Teachers are excited even if you wouldn't like to accept their teaching．

C. Though few，there are still some students who can learn even if they don't like the teacher．

D. Having a bad relationship with your teachers does more or less harm to your studies．

【題目】閱讀下列材料，回答問(wèn)題。

從西伯利亞南下的寒冷空氣，它的厚度總是有限的，在南下的過(guò)程中，遇到低矮的丘陵山地時(shí)，還能蜂擁而過(guò)，但是一遇到高大巍峨的山脈時(shí)，它就會(huì)受到攔阻，常常要停留一段時(shí)間才能越過(guò)或繞過(guò)山脈繼續(xù)南下。在當(dāng)?shù)剌^強(qiáng)太陽(yáng)輻射的“烘烤”下，冷空氣迅速變暖，這樣一來(lái)，越過(guò)山去的冷空氣寒冷程度就大大減弱了。所以盡管最初冷空氣可以冷到-40℃至--50℃，可是當(dāng)它到達(dá)華南地區(qū)的時(shí)候已經(jīng)大大增暖，并不能使當(dāng)?shù)氐臉?shù)葉變黃脫落，也不會(huì)使河面上出現(xiàn)薄冰。

【題目】There once lived a rich businessman who had a lazy son. The businessman wanted his son to realize the value of labour.

One day, he told his son, "Today, I want you to earn something. If you fail, you won't have your meal tonight."

The boy didn't want to find a job, so he asked his mother for help. She gave him a gold coin. In the evening, when the father asked his son what he had earned, the son showed him the gold coin. The father then asked him to throw it into the well (水井). The son did as he was told.

As he returned home and gave the coin to his father, he was asked to throw it into the well. The boy cried, "Dad! My body is aching. I'm tired.
