本課語(yǔ)言點(diǎn)
1. For more than a quarter of a century， evidence has been increasing that children's exposure to violence on television has long-lasting effects on their behavior.
a quarter （of）“四分之一”，如：a quarter of a pound（四分之一磅）；a quarter of a century（四分之一世紀(jì)）；a quarter of a mile（四分之一英里）；a quarter （of a dollar） （25美分）；a quarter of a million（25萬(wàn)）；a quarter （of an hour）（15分鐘）。
…that children's exposure to violence on television…
that 引導(dǎo)的是一個(gè)同位語(yǔ)從句，這個(gè)同位語(yǔ)從句沒(méi)有直接跟在名詞evidence的后面，而是被has been increasing隔開(kāi)了。同位語(yǔ)的作用是對(duì)它所說(shuō)明的名詞作進(jìn)一步解釋?zhuān)f(shuō)明這個(gè)名詞指的是誰(shuí)或什么。如：
1）I had no idea that he told us a lie. （我不知道他對(duì)我們說(shuō)了謊話。）
2）You have to produce enough evidence that he is guilty.（你得拿出足夠的證據(jù)說(shuō)明他有罪。）
3）There was little possibility that they would succeed. （他們成功的可能性極小。）
4）There can be no doubt that TV violence affects children. （毫無(wú)疑問(wèn)，暴力電視節(jié)目對(duì)兒童有不良影響。）

2）The cement factory has much effect on the environment.（水泥廠對(duì)環(huán)境的影響很大。）
3）His persuasion had little effect on her.（他的勸說(shuō)對(duì)她沒(méi)什么作用。）
2.…the amount of television time allocated each week to violent programs increased significantly.
…the number of violent acts on television…h(huán)as increased…。
上面兩個(gè)句子中分別用了amount和number兩個(gè)詞。amount用來(lái)修飾從體積，重量，金額等方面著眼的東西，一般在of后接用不可數(shù)名詞；而number則用以修飾可數(shù)的人或物。在第一個(gè)句子中，amount of后面用的是不可數(shù)名詞time，第二個(gè)句子中number of后面用的是可數(shù)名詞acts.再請(qǐng)看例句：
1）A large amount of money has been spent on this project.（一大筆錢(qián)已經(jīng)花在了這個(gè)工程上。）
2）The amount of work assigned to him was formidable.（分配給他做的工作量極大。）

請(qǐng)注意區(qū)別act和action這兩個(gè)名詞。①這兩個(gè)名詞都表示“行為”，“行動(dòng)”的意思，?？苫Q使用。act強(qiáng)調(diào)行為的結(jié)果，而不涉及行為的動(dòng)機(jī)與性質(zhì)，常是即興，瞬間的舉動(dòng)；action偏重于動(dòng)作的方式和過(guò)程。②act行為的發(fā)出者可以是人也可以是物；action只是物。③在須用不可數(shù)名詞表示總的概念時(shí)，多用action，而一般不用act.如：
1） The time has come for action/act.（采取行動(dòng)的時(shí)間了。）
2） The thoughtless young man did another foolish act.（那個(gè)魯莽的年輕人又做了件傻事。）
3） Every sudden emotion quickens the action of the heart.（每件突如其來(lái)的令人激動(dòng)的事情都能加快心跳。）
4） Actions speak louder than words.（事實(shí)勝于雄辯。）
3.Given the amount of time that children watch television， it has become one of the most powerful models they want to follow.
given在本句中用作介詞，意思是considering， taking into account（考慮到），在詞匯部分我們已作了比較詳細(xì)的講解，再請(qǐng)看兩個(gè)例句：
1）Given they are fresh from university， they've done a great job.（考慮到他們剛走出大學(xué)校園，他們干得不錯(cuò)。）
2）Given that he has always been dreaming of visiting the great wall， it seems cruel not to take him to Beijing.（他一直夢(mèng)想游長(zhǎng)城，不帶他去北京似乎太殘酷了。）

4.Children naturally often want the toys shown on and advertised during these programs.
Shown on and advertised during these programs 在本句中的作用是分詞短語(yǔ)作定語(yǔ)，相當(dāng)于被動(dòng)語(yǔ)態(tài)的定語(yǔ)從句，修飾toys.
1）Last night， we saw a documentary dubbed in English.（昨晚，我們看了一部用英文譯制的記錄片。）
2）The play put on by the first-year students was very good.（一年級(jí)學(xué)生演出的劇目很好。）
3）The letters written in pencil are from my brother.（那些用鉛筆寫(xiě)的信是我弟弟帶來(lái)的。）

He doesn't care about and has no interest in other people's opinion.（對(duì)別人的觀點(diǎn)他不在乎也沒(méi)興趣。）
5.With these toys， their play tends to be more imitative than imaginative.
With 在本句中表示原因，意思是“由于，因”，如：
1）He is in bed with flu.（他因患流感臥病在床。）
2）Her eyes were dim with tears.（她的雙眼因淚水而模糊。）
3）The boy's face was white with nervousness.（那個(gè)男孩的臉因緊張而發(fā)白。）

1）Plants tend to die in hot weather if you don't water them.（植物在炎熱天氣如不澆水容易枯死。）
2）He tends to get impatient if you ask him more than two questions.（如果你問(wèn)他兩個(gè)以上的問(wèn)題，他往往會(huì)不耐煩。）
6.The narrow range of most violence-related toys advertised on television jeopardizes the role of play in helping children make better sense of their own feelings and interpret their world.
在第三單元中，我們已經(jīng)學(xué)過(guò)range這個(gè)詞，意思是“山脈”，“（在某范圍內(nèi)）變動(dòng)，變化”。而在本句中，range的意思是“范圍”，如：
1）His reading is of very wide range.（他的閱讀面很廣。）
2）Over the long range， the most important step will be a general tax reform.（從長(zhǎng)遠(yuǎn)看，重要的步驟是全面實(shí)行稅制改革。）
Make sense of 意思是“了解；弄明白”。如：
1）I can not make any sense of what he says.（他的話我弄不懂。）
2）His lecture helped me make better sense of the poem.（他的講解幫助我更好地理解這首詩(shī)。）
3）I could make no sense of his carelessly written letter.（我看不懂他馬馬虎虎寫(xiě)的那封信。）
7.Many preschool teachers do not like to have commercially made toy weapons brought into the classroom and welcome hearing your concerns about this matter.

2）He had his files destroyed before he left.（在離開(kāi)前，他把文件都?xì)Я?。?BR> 3）She wanted to have the rooms repainted before moving in.（她想在搬入前把房間重新粉刷一遍。）
welcome 在本舉句中作動(dòng)詞用，這個(gè)詞也可以作名詞和形容詞用。請(qǐng)看下面的例句，注意welcome在各例句中的詞類(lèi)。
1）He ran to the door to welcome his friends. （他向門(mén)口跑去，歡迎他的朋友。）
2）Welcome to Beijing.（歡迎到北京來(lái)。）
3）Her marriage was not welcomed by the family.（她的婚姻不被家人接受。）
4）They gave her a warm welcome.（他們給她以熱烈歡迎。）

6）You are welcome to use my bike.（我的自行車(chē)你盡管用。）
7）He is a welcome guest.（他是個(gè)受歡迎的客人。）
