九年級(jí)英語(yǔ)第十四、十五單元重難點(diǎn)
一、疑點(diǎn)難點(diǎn)
1. Have you turned off1 your radio?你關(guān)掉收音機(jī)了嗎?
疑點(diǎn):turn off表示“切斷、關(guān)上”之意,用于指切斷電源、關(guān)上水管等。它的反義詞是turn on。當(dāng)關(guān)掉的東西是代詞時(shí),把代詞放在中間。
如:His mother told him to turn off TV and do his homework.他母親叫他關(guān)掉電視去做作業(yè)。
The tap2 is broken3.If you want to save4 water,you must turn it off.
難點(diǎn):與此相關(guān)的短語(yǔ)還有turn up“開(kāi)大聲”,turn down“關(guān)小點(diǎn)聲”。用法同turn off/on.
如:It is too noisy. Please turn your radio down.
I can’t hear clearly6. Would7 you please turn the tape up?
2.In the past twelve months they’ve had8 three major9 concerts10 and made11 a hit CD12.在過(guò)去的12個(gè)月里他們舉行了3次大型
演唱會(huì),出了一盤(pán)火暴的CD。
疑點(diǎn):for/in the past/last twelve months/years/days/etc.常與現(xiàn)在完成時(shí)態(tài)連用。
如:(1)For the past few13 days he has been ill.幾天來(lái)他一直生病。
(2)She has been ill for the last three days.這三個(gè)星期他在生病。
(3)In the past three years we have learned14 two thousand English words.
3年來(lái)我們學(xué)了2000個(gè)英語(yǔ)單詞。
難點(diǎn):用于肯定句時(shí),和以上短語(yǔ)連用的動(dòng)詞必須是延續(xù)性動(dòng)作。
如:He has had(而不是bought)the book for three years.他已經(jīng)買(mǎi)這本書(shū)三年了。
You have kept(不用borrow) the book for two weeks.你已經(jīng)借這本書(shū)兩個(gè)星期了。
3. This program15 started in 1980 and so far has brought16 thousands of overseas17 Chinese students to China to look for their families’roots.這個(gè)項(xiàng)目是1980年開(kāi)始的,到目前為止已經(jīng)幫助了幾千名海外中國(guó)學(xué)生來(lái)中國(guó)尋根。
疑點(diǎn):so far意為“到目前為止”,相當(dāng)于till now/up to now,可用于句首或句末,用作狀語(yǔ),表示范圍、程度或距離,通常作為現(xiàn)在完成時(shí)的時(shí)間狀語(yǔ)出現(xiàn)。
如:I have read many foreign18 stories so far.
難點(diǎn):so far as5 意為“就…而論”、“到…程度”,表示程度、距離等。
如:So far as I know,he has been to Beijing many times.據(jù)我所知,他已去過(guò)北京許多次了。
4. I agree19 with you. 我同意你的看法。
疑點(diǎn):agree with sb./sb.’s idea/ sb.’s view同意某人,同意某人的觀點(diǎn)、想法、主意。
如:My mother doesn’t agree with my father and me.我媽媽不同意我和爸爸的想法。
難點(diǎn):agree還有許多的用法
(1)用于簡(jiǎn)短回答中“同意”或“贊成”。如:Chocolate is good for your health20. Do you agree?
Yes,I agree./No,I don’t agree.
(2)agree to do sth同意去做某事。如:I agree to ask someone21 for help.我同意向別人求助。
(3)agree to sth贊成某個(gè)建議、安排等。如:He agreed22 to your suggestion23.他贊成你的建議。

疑點(diǎn):hear of/about聽(tīng)說(shuō),接名詞、代詞或動(dòng)名詞。如:I have never heard of the story before.

如:I heard that his father died27 yesterday.
2)hear from=get/receive a letter from意為“收到…的信”,“得到…的消息”from后面加表示人的名詞或代詞
如:How often do you hear from your father?你每隔多久收到你父親的來(lái)信?

疑點(diǎn):be made from 意思是“由… 制成”,但制成品不能看出原材料。
如:Paper is made from wood.紙是由木頭制成的。
難點(diǎn):be made還可以構(gòu)成其他詞組,注意區(qū)分。
(1)be made of意為“由…原材料制成”,主語(yǔ)為制成品,而且能看出原材料,of后面接表示原材料的名詞。如:This jacket is made of cotton28.這件上衣是棉花做的。
(2)be made in表示某一產(chǎn)品在某地生產(chǎn)或制造,in后面跟表示地點(diǎn)的名詞。

二、重點(diǎn)講解
1. Have you packed31 yet32?你打包了嗎?
(1)這是一個(gè)現(xiàn)在完成時(shí)的句型,它是在兩個(gè)時(shí)間上,一是過(guò)去,一是現(xiàn)在。它的動(dòng)作發(fā)生在過(guò)去,但對(duì)現(xiàn)在有影響或結(jié)果,而這種影響和結(jié)果是說(shuō)話人的興趣所在,所以常常后面不用時(shí)間狀語(yǔ)。Have/has+動(dòng)詞的過(guò)去分詞,是它的基本結(jié)構(gòu)。
如:Someone has broken the door.有人把門(mén)打破了。(結(jié)果,門(mén)仍破著)
(2)pack30包裝,把……裝箱pack sth(up)into…整理行裝

clean sth down清掃,擦干凈。如:Clean down the walls.把墻上的塵土掃下。
3. I have not done any of these things yet because my grandfather came36 to chat37 to me.那些事情我一樣也還沒(méi)做,因?yàn)槲易娓竵?lái)和我聊天。
(1)because連詞,因?yàn)?。如:I did38 it because they asked me to do it.我做這事是因?yàn)樗麄円易觥?/p>
(2)because所表達(dá)的原因是不知道的,如要表達(dá)明顯的理由,或被認(rèn)為是知道的,就用as,for,或so。如:As it is raining,you had better take a taxi.=It is raining,so you had better take a taxi.既然下雨,你最好坐
出租車來(lái)。
(3)because of 后面加名詞或名詞短語(yǔ)。
如:Because of his bad legs,he could39 not walk so fast as the others40.因?yàn)樗耐扔忻?,他不能和別人一樣走得快。
4.Be sure not to miss them if they come to a city near you-if you can get tickets.如果他們到了一個(gè)離你近的城市,務(wù)必不要錯(cuò)過(guò),如果你能得到票的話。
be sure to do務(wù)必,一定要。如:Be sure to tell me when you arrive home.到家后務(wù)必要告訴我一聲。
★注意動(dòng)詞不定式to do的否定形式,要直接在to do前加not。如:Be sure not to wake41 up the sleeping boy.一定不要吵醒在睡覺(jué)的孩子。
5. I feel like I have done something that wasn’t important42 to me before.我想我做了些原先對(duì)我并不重要的一些事情。
feel like+ doing sth.想要,欲要。如:I don’t feel like eating a big meal43 now.我現(xiàn)在不想吃大餐。
6. They provide44 homes for many endangered45 animals,and help to educate46 the public47 about caring48 for them.我們?yōu)闉l危動(dòng)物們提供住所,并教育公眾照顧他們。
provide sth for sb /provide sb with sth把某物提供給某人。如:These letters should provide us with all the information49 we need.這些信應(yīng)該為我們提供所需的全部信息。
三、語(yǔ)法展示
(一)特殊副詞的用法
現(xiàn)在完成時(shí)態(tài)我們?cè)谇懊娴囊?、二個(gè)單元中已講述過(guò),所以本單元只講現(xiàn)在完成時(shí)態(tài)與幾個(gè)副詞的關(guān)系。
1. ever26, never
ever“曾經(jīng)”,表示從過(guò)去到目前為止的時(shí)間,用于現(xiàn)在完成時(shí)態(tài)的疑問(wèn)和含有最高級(jí)的從句中,否定句中常用never代替ever,在反意疑問(wèn)句中,附加問(wèn)句用肯定。
如:(1)Have you ever been to Hefei?你曾去過(guò)合肥嗎?
(2)This is the most interesting film that I have ever seen50.這是我曾看過(guò)的電影中最有趣的一部。
(3)He has never been to the Great Wall,has he?他從未去過(guò)

如:(1)Has your sister still lived here?你妹妹仍然住在這兒?jiǎn)?
(2)I have just finished51 lunch.我剛吃過(guò)中飯。
(3)I saw52 her mother just now.我剛才看見(jiàn)了她母親。
3. before,ago
兩者都可作副詞用,before表示過(guò)去時(shí)間的以前,可獨(dú)立使用,泛指“以前”,可用于現(xiàn)在完成時(shí)態(tài)或一般過(guò)去時(shí)態(tài)。ago不能獨(dú)立使用,要置于時(shí)間段的詞組之后,只能用于過(guò)去時(shí)態(tài),表示從現(xiàn)在算起以前的時(shí)間。但可以用在情態(tài)動(dòng)詞加完成時(shí)態(tài)結(jié)構(gòu)中,表示現(xiàn)在對(duì)過(guò)去發(fā)生的事情的推測(cè)。此外與since連用,構(gòu)成since…ago用于現(xiàn)在完成時(shí)態(tài)。
如:(1)She has seen the film before. 她以前看過(guò)這部電影。

4. since,for
since:“自從”,表示的是一個(gè)時(shí)間點(diǎn),可用作介詞,也可作連詞。用作介詞時(shí),后接指時(shí)間點(diǎn)的名詞或短語(yǔ);用作連詞時(shí),后跟一個(gè)時(shí)間狀語(yǔ)從句,但其前的謂語(yǔ)動(dòng)詞或主句的謂語(yǔ)動(dòng)詞須用現(xiàn)在完成時(shí)。for構(gòu)成的短語(yǔ)在現(xiàn)在完成時(shí)里,表示時(shí)間的長(zhǎng)度,后須跟“一段時(shí)間”,不可跟“時(shí)間點(diǎn)”。
如:(1)He has worked at that factory since he came to the city.他到這城市以來(lái)一直在這家工廠工作。
(2)I have studied English for three years. 我學(xué)習(xí)英語(yǔ)已有三年了。
(二)have been to 與have gone to 的區(qū)別
