【解析】

試題分析:考查時態(tài)。句意:—你在107頁上可以找到這個數(shù)學題的答案!!太簡單了!我想知道為什么我就想不起來這個答案呢?根據(jù)句意說明我沒有想起這個答案是過去的事情,故使用一般過去時。故C正確。

考點:考查時態(tài)

點評:英語中的時態(tài)主要由動詞的形式?jīng)Q定,因此在學習英語時態(tài)時,要注意分析動詞形式及具體語境,想象在那個特定的時間動作所發(fā)生的背景,這個動作是經(jīng)常性動作、一般性動作、進行性動作、完成性動作還是將要發(fā)生的動作。

根據(jù)短文內(nèi)容,從短文后的選項中選出能填入空白處的最佳的選項。選項中有兩項為多余選項。
Although many Chinese students say that their knowledge of English grammar is good, most would admit that their spoken English is poor. Whenever I speak to a Chinese student, they always say,“ My spoken English is poor.”  【小題1】I would like to suggest that there may be some reasons for their problems with spoken English.
First, they fail to find suitable words to express themselves due to a limited vocabulary.【小題2】However, you can speak with a limited vocabulary, if you choose a positive attitude. Others will follow you as long as you use the words that you know.
【小題3】  Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet students should remember that their goal should be FLUENCY NOT ACCURACY. Your aim in writing is to be accurate following the rules for grammar and using the right words and spelling them correctly. However, in speaking your aim is fluency. You want to get your message across, to talk to someone in English, as quickly and as well as you can, even though sometimes you may use a wrong word or tense, but it doesn't matter.【小題4】 
The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All that hearing is necessary for you to start speaking.
Fourth, most Chinese students are reactive rather than proactive language learners. Instead of actively seeking out opportunities to improve their spoken English they passively wait for speaking opportunities to come to them and wonder why their English always remains poor.【小題5】

A.The person you are speaking to will understand you and make allowances for any mistakes he hears.
B.They may try to avoid making similar mistakes next time.
C.Obviously the better answer is to expand their vocabulary.
D.If you have this proactive outlook, then you will see English opportunities wherever you go.
E. However, their spoken English does not have to remain “poor”!
F. Second, they are afraid of making mistakes.
G. The second reason lies in the reluctance of using what has just been learned.

Tips for Being a Good Neighbor

1._______________

No one likes a noisy neighbor. Do you hold parties that last all night? Do you leave your dog outside to bark all day? Remember that not everyone has the same schedule as you do, so use some common sense. Keep noise to the lowest level. If you’re holding a party that’s likely to be loud, invite everyone within earshot.

2._______________

       It’s much easier to solve any problem with neighbors if you have a friendly relationship with those around you. Furthermore, you may realize that you have things in common and make a lifelong friend.

3._______________

       Once you know your neighbors, then you’ll also know if something seems out of place in the neighborhood. Are strange people carrying expensive things out of one neighbor’s house? Have several days passed since your elderly neighbor last collected his newspaper? The benefit of keeping an eye out for unusual behavior in the neighborhood is that others will do the same for you.

4._______________

       It never hurts to follow the Golden Rule: Do to others what you would like them to do to you. Treat your neighbors with respect. Offer to drive an elderly neighbor to the grocery store. Volunteer to collect mail while a neighbor is on vacation. The more often you lend a helping hand, the more likely that your neighbors will do the same for you when you need a little help.

5._______________

Don’t just limit your neighborly actions to your block or street. Remember that everyone who lives in a community has the ability to help make it a better place. Think about your passion and find a way to do it on a volunteer basis in your town. Volunteer at the local library. Enjoy working with kids. Consider becoming a scout leader. Whatever your passion is, there’s sure to be a thing suitable for you to help in the local community.

根據(jù)短文內(nèi)容,從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

The Internet has opened up a whole new online world for us to meet, chat and go where we have never been before.

But just as in face to face communication, there are some rules of behavior that should be followed when you are online.   1. Imagine how you’d feel if you were in the other person’s shoes.

For anything you’ re about to send: ask yourself, “Would I say this to the person’s face?” if the answer is no, rewrite and reread.   2. 

If someone in the chat room is rude to you, your instinct(本能)is to fire back in the same manner. But try not to do so.   3.  If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

 4.  Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything.  Having good manners yourself doesn’t give you permission to correct everyone else.   5. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.

It is not polite to ask others personal questions such as their age, sex and marital status(婚姻狀況). Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.

A.Everyone was new to the network once.

B.If you do decide to tell someone about a mistake, point it out politely.

C.It’s natural that there are some people who speak rudely or make mistakes online.

D.The basic rule is simple: treat others in the same way you would want to be treated.

E. You should either ignore the person, or use your chat software to block their messages.

F. When you send short messages to a person online, you must say something beautiful to hear.

G. Repeat the process till you feel sure that you’ d feel comfortable saying the words to the person’ s face.
