新概念英語(yǔ)第2冊(cè)Lesson52重點(diǎn)內(nèi)容解析
重要句型或語(yǔ)法
1、現(xiàn)在完成進(jìn)行時(shí)
該時(shí)態(tài)是第二冊(cè)區(qū)別與第一冊(cè),新增出來(lái)的時(shí)態(tài)。主要用來(lái)表示過(guò)去發(fā)生的動(dòng)作,持續(xù)到現(xiàn)在,而且還會(huì)繼續(xù)持續(xù)下去。如:
I have been working hard all morning.
I have been trying to get my new room in order.
2、同源副詞
所謂“同源副詞”指的是某些形容詞同時(shí)具有兩個(gè)不同形式的副詞,而且含義不一樣。比如:形容詞deep有兩個(gè)副詞,即deep(物理意義上的深的)和deeply(抽象意義上的深深地),比如:
The cave is very deep. (這個(gè)洞穴很深。)
They are deep in love with each other.(他倆相互深愛(ài)著對(duì)方。)
課文主要語(yǔ)言點(diǎn)
We have just moved into a new house and I have been working hard all morning. 1)本句話是對(duì)比現(xiàn)在完成時(shí)和現(xiàn)在完成進(jìn)行時(shí)的典型例子。前半句用了現(xiàn)在完成時(shí),因?yàn)橐磉_(dá)的是剛剛搬進(jìn)了新家,而后半句用了現(xiàn)在完成進(jìn)行時(shí),是因?yàn)橐磉_(dá)整個(gè)上午一直都在忙著。 2)move into...,搬進(jìn)某處。注意與move in(搬進(jìn),不及物,后面不接賓語(yǔ))和move to...(搬到某地,是較大的地點(diǎn)名稱)的區(qū)別。 3)hard,努力地,是個(gè)副詞。注意該詞源于形容詞hard(努力的),需要注意區(qū)分副詞hard和hardly(幾乎不)。 4)all morning,整個(gè)上午,相當(dāng)于all the morning。注意“all+時(shí)間”表示持續(xù)的一段時(shí)間,是進(jìn)行時(shí)的標(biāo)志。
I have been trying to get my new room in order. 1)本句話之所以也采用了現(xiàn)在完成進(jìn)行時(shí),是因?yàn)檫@句話時(shí)緊接著上句話中所說(shuō)的have been working all morning,解釋到底在忙什么。 2)get...in order,把...整理好。be in order,井然有序。相反的表達(dá)的是:be out of order。
This has not been easy because I own over a thousand books. 1)句中的This has not been easy可以改為It is not easy,因?yàn)樵摼湟磉_(dá)的是要做好這件事情不容易的客觀事實(shí)。 2)own,擁有。該詞也可以用作形容詞,表示“自己的”。其常用的短語(yǔ)是:on one's own,獨(dú)自、獨(dú)立。
To make matters worse, the room is rather small, so I have temporarily put my books on the floor. 1)to make matters worse,固定短語(yǔ),表示“更糟糕的是...” 2)rather,非常、相當(dāng)。該詞一般用來(lái)修飾貶義的或消極的形容詞或副詞,和它意思相同但用法反的是fairly,該詞主要用來(lái)修飾褒義的或是積極的形容詞或副詞。 3)temporarily,暫時(shí)地、臨時(shí)地。源自形容詞temporary(暫時(shí)的、臨時(shí)的)。
At the moment, they cover every inch of floor space and I actually have to walk on them to get in or out of the room. 1)at the moment,此刻、現(xiàn)在。相當(dāng)于now。 2)cover,占據(jù)、覆蓋。 3)every inch of+地點(diǎn),表示“某個(gè)地方全是...” 4)space,空間。 5)actually,實(shí)際上。源自形容詞actual(實(shí)際上的)。
A short while ago, my sister helped me to carry one of my old bookcases up the stairs. 1)a short while,一會(huì)兒。while相當(dāng)于moment。 2)up the stairs,上樓。
She went into my room and got a big surprise when she saw all those books on the floor. 1)get a big surprise,感到很驚訝。 2)注意all those books中的all起強(qiáng)調(diào)作用。
This is the prettiest carpet I have ever seen,' she said. 1)This is the+高級(jí)+名詞+sb. has/have ever done,表示“這是某人見(jiàn)過(guò)的或做過(guò)的...的...”。名詞后面省略了關(guān)系代詞that。 2)carpet,地毯(用來(lái)踩的)。注意與blanket(毛毯,用來(lái)蓋的)的區(qū)別。
She gazed at it for some time then added, 'You don't need bookcases at all. You can sit here in your spare time and read the carpet!' 1)gaze at。注視、凝視。相當(dāng)于stare at。 2)句中的then added前面好加上and。add,補(bǔ)充道、接著說(shuō)。 3)not...at all,根本不、一點(diǎn)也不。 4)in one's spare time,在業(yè)余時(shí)間。 5)read the carpet,此處的carpet指的是作者的over a thousand books。

重要句型或語(yǔ)法
時(shí)態(tài)復(fù)習(xí)
本課主要對(duì)比復(fù)習(xí)一般過(guò)去時(shí)、現(xiàn)在完成時(shí)和現(xiàn)在完成進(jìn)行時(shí)的用法。比如:
I stayed at this hotel five years ago.
Have you ever stayed at his hotel?
I have been staying at this hotel for three weeks.
課文主要語(yǔ)言點(diǎn)
At last firemen have put out a big forest fire in California. 1)注意at last放在句首,突出了后面發(fā)生的事情,具有強(qiáng)調(diào)作用。 2)put out,撲滅、熄滅。 3)a big forest fire,森林大火。
Since then, they ahve been trying to find out how the fire began. 1)since then,自從那之后。這是完成時(shí)的標(biāo)志性時(shí)間狀語(yǔ)。 2)本句的謂語(yǔ)動(dòng)詞try采用了現(xiàn)在完成進(jìn)行時(shí),說(shuō)明消防員一直都在努力撲火。 3)find out,查清楚、弄明白。 4)how the fire began,在句中用作find out的賓語(yǔ)。注意雖然這句話時(shí)問(wèn)句,但因?yàn)楸挥米髁藦木?,所以要恢?fù)正常語(yǔ)序。此外,要注意begin用了一般過(guò)去時(shí),是因?yàn)樽髡呦氡磉_(dá)的意思是:火在過(guò)去是怎么燒起來(lái)的。
Forest fires are often caused by broken glass or by cigarette ends which people carelessly throw away. 1)本句話采用了一般現(xiàn)在時(shí),是因?yàn)樵陉U述客觀事實(shí)。 2)which引導(dǎo)的是限定性定語(yǔ)從句,修飾先行詞broken glass和cigarette。 3)carelessly,馬虎地、不小心地。相反的表達(dá)是carefully。 4)throw away,丟棄、丟掉。
Yesterday the firemen examined the ground carefully, but were not able to find any broken glass. 1)examine,檢查、檢測(cè)。其動(dòng)作名詞為examination,可簡(jiǎn)寫(xiě)為exam;表人的名詞為examiner。 2)注意but后面省略了they,因?yàn)榍昂笾髡Z(yǔ)是一致的。
They were also quite sure that a cigarette end did not start the fire. 1)be sure of/about sth.,對(duì)...很肯定。如果后接句子,則用法為:be sure that...。 2)start,引起。
This morning, however, a firemen accidentally discovered the cause. 1)注意however可以放在句首、句中和句末,但:在句首時(shí),后面要用逗號(hào)隔開(kāi);在句中時(shí),前后都要用逗號(hào)隔開(kāi);在句末時(shí),前面要用逗號(hào)隔開(kāi)。 2)accidentally,偶然地。該詞源自accident(偶然性或突發(fā)性事故)。 3)discover,發(fā)現(xiàn)、探索。注意該詞的構(gòu)詞方式為:dis-+cover,其中的c在發(fā)音時(shí)要濁化為[g]。其名詞形式為discovery。 4)cause,起因。該詞可以用作動(dòng)詞,表示“導(dǎo)致”。
He noticed the remains of a snake which was wound round the electric wires of a 16,000-volt power line. 1)notice,注意到。該詞可以用作名詞,表示“通知;告示”。 2)remains,尸體、殘骸。 3)which引導(dǎo)的是限定性定語(yǔ)從句,修飾先行詞a snake。 4)wind round,纏繞在...上。注意wind在此用作動(dòng)詞,其中的i的發(fā)音為[aɪ],要注意wind作為名詞中的i的發(fā)音為[ɪ]。此外,還要注意的是作為動(dòng)詞的wind,其過(guò)去式為wound,但其中的ou發(fā)音為[au],要注意與名詞wound(傷口)的發(fā)音區(qū)別,其中的ou發(fā)音為[u:]。 5)electric,帶電的。其名詞為electricity。 6)power line,電力線。
In this way, he was able to solve the mystery. 1)in this way,通過(guò)這個(gè)辦法。 2)be able to,好不容易得以、能夠。 3)solve the mystery,解決謎團(tuán)。
The explanation was simple but very unusual. 1)explanation,解釋。源自動(dòng)詞explain。 2)simple,簡(jiǎn)單的。注意與easy的區(qū)別:simple側(cè)重事情顯而易見(jiàn),不難懂;而easy側(cè)重事情的難度小,容易做。 3)unusual,不尋常的。源自u(píng)sual。
A bird had snatched up the snake from the ground and then dropped it on to the wires. The sanke then wound itself round the wires. 1)snatch up,抓起。 2)drop,丟掉、丟棄。注意其過(guò)去式要雙寫(xiě)p。 3)wind oneself round,纏繞在...上面。

課文主要語(yǔ)言點(diǎn)

It was still early when I returned home. 注意home的短語(yǔ)用法,大多數(shù)情況下,home作為副詞,所以前面都不接介詞,如go home、arrive home、come home等。例外情況有:stay at home、be at home。
The children were at school, my husband was at work and the house was quiet.
