B: I am 【1】 TV.

A: Do you 【2】 why we can watch TV programs 【3】 foreign countries?

B: Sorry, I don’t know. Why?

A: That’s because of man-made satellites.

B: How useful they are! We must study hard to 【5】 the technology.

【答案】

【1】watching

【2】know

【3】from

【4】receive

【5】master

【解析】

【1】句意：——你好，明明，你在做什么？——我正在看電視。

根據(jù)空后的TV以及下文“…why we can watch TV programs…”可知，明明現(xiàn)在正在看電視，這里考查watch，是一個(gè)動(dòng)詞，意為“觀看”。問題中使用的是現(xiàn)在進(jìn)行時(shí)，答語(yǔ)中也用現(xiàn)在進(jìn)行時(shí)，這里應(yīng)填現(xiàn)在分詞形式。故答案為watching。

【2】句意：——你知道我們?yōu)槭裁茨芸赐鈬?guó)的節(jié)目嗎？——對(duì)不起，我不知道。

根據(jù)下面的回答“Sorry, I don’t know”可知，這里是問對(duì)方“知道……嗎”，考查know，是一個(gè)動(dòng)詞，意為“知道”。句中使用了一般現(xiàn)在時(shí)態(tài)，這里應(yīng)填動(dòng)詞原形，故答案為know。

【3】句意：——你知道我們?yōu)槭裁茨苡^看外國(guó)的節(jié)目嗎？——對(duì)不起，我不知道。

根據(jù)句意可知，這里表示“來自外國(guó)的節(jié)目”，用介詞from。故答案為from。

【4】句意：——它們能發(fā)送和收集信息嗎？——是的，它們能。

根據(jù)句意可知，空前用send與message搭配，表示“發(fā)送信息”，按照常識(shí)，人造衛(wèi)星可以發(fā)送信息，也可以收集信息，故這里應(yīng)用receive，表示“接收”，與send并列，也用動(dòng)詞原形。故答案為receive。

【5】句意：我們必須努力學(xué)習(xí)掌握技術(shù)。

根據(jù)句意可知，人造衛(wèi)星非常的有用，所以這里表示“努力學(xué)習(xí)來掌握技術(shù)”，考查master，意為“掌握”，是一個(gè)動(dòng)詞。由句子結(jié)構(gòu)可知，to…是動(dòng)詞不定式在句中作目的狀語(yǔ)，這里填動(dòng)詞原形。故答案為master。

【題目】 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!

【題目】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.

【1】What is the biggest problem with Black Friday?

_________________________________________________________________________

【2】Why do people like going shopping on Black Friday?

_________________________________________________________________________

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