【答案】

1watching

2know

3from

4receive

5master

【解析】

1句意:——你好,明明,你在做什么?——我正在看电视。

根据空后的TV以及下文“…why we can watch TV programs…”可知,明明现在正在看电视,这里考查watch,是一个动词,意为“观看”。问题中使用的是现在进行时,答语中也用现在进行时,这里应填现在分词形式。故答案为watching

2句意:——你知道我们为什么能看外国的节目吗?——对不起,我不知道。

根据下面的回答“Sorry, I don’t know”可知,这里是问对方“知道……吗”,考查know,是一个动词,意为“知道”。句中使用了一般现在时态,这里应填动词原形,故答案为know

3句意:——你知道我们为什么能观看外国的节目吗?——对不起,我不知道。

根据句意可知,这里表示“来自外国的节目”,用介词from。故答案为from

4句意:——它们能发送和收集信息吗?——是的,它们能。

根据句意可知,空前用sendmessage搭配,表示“发送信息”,按照常识,人造卫星可以发送信息,也可以收集信息,故这里应用receive,表示“接收”,与send并列,也用动词原形。故答案为receive

5句意:我们必须努力学习掌握技术。

根据句意可知,人造卫星非常的有用,所以这里表示“努力学习来掌握技术”,考查master,意为“掌握”,是一个动词。由句子结构可知,to…是动词不定式在句中作目的状语,这里填动词原形。故答案为master

【题目】 One Sunday, I decided to tidy my bookshelf up. Suddenly, a white envelope fell to the floor. I was surprised! I couldn't remember putting the envelope on my shelf. It must have been years ago! Anyway, I opened the envelope carefully. Inside it, there was a folded piece of paper. I read it. It was a letter written by my mom.

My dear children, I love you so much! This is not a letter to be posted. I have written this in the hope that one day you will find it. Yes, I wanted to let you know something that I thought was not suitable to express face to face.

Life is too short and uncertain. What I say is not new at all, but why I say it is important. If you are reading this, I am no longer with you. You are alone now. I'm not there to help you or give you any kind of advice. But I have faith(信心) that the steps you take will be sound and wise.

The world around you can be confusing. But if you look inside yourself, you can light your path and figure out where to go. Remember the saying “you reap what you sow(播种)”. The way you act will have an impact on your life. Be careful and aware of every step. Be positive as much as possible. All of you are great children. I hope you can understand what I mean. Be kind to others and to yourself.

Yours affectionately(挚爱地) Mom

【题目】Black Friday

Thanksgiving is always on Thursday. The day after it has been known as Black Friday. It is the start of the holiday shopping season, and it has been the busiest shopping day of the year in the USA since 2005.

Most stores offer big sales on Black Friday. They open their doors quite early in the morning. They try to attract shoppers with big discounts. Some items(商品)like TVs and clothes are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.

Black Friday is a great time to go shopping. However, there are problems. The biggest one is that there are not enough low-priced items. Each store may only have a few. These items are in great need, so people stand in long lutes to get them. They may wait three to four hours before a store opens. They may be hoping to get a low price on a TV or computer, but not everybody can get one. Some people leave, disappointed.

The situation makes people worried. Some Black Friday events have been crazy. There have been fights over toys among shoppers. Some workers have even been hurt by large crowds. But most Black Friday events are safe and fun. Still, if you plan to go, you will expect large crowds and a bit of pushing.

So where does the name "Black Friday" come from? It was first used in Philadelphia in the 1950s. The police called this day Black Friday because of the heavy traffic it caused. In the 1960s, stores tried to rename the day "Big Friday". It did not stick. The name "Black Friday" continued to spread across the country. It seems that it is here to stay.

Now people all over the country take part in Black Friday events. It is even spreading to other parts of the world. Stores have held Black Friday events in the UK, Australia, and Brazil since 2012. In Mexico, stores offer a weekend of discounts every year. They call it "E1Buen Fin", which means" the good weekend" in Spanish. I guess people everywhere like to buy things.

1What is the biggest problem with Black Friday?

_________________________________________________________________________

2Why do people like going shopping on Black Friday?

_________________________________________________________________________

3Will you go shopping on Black Friday? Why or why not?

_________________________________________________________________________
