    新概念英語第2冊Lesson52重點內(nèi)容解析
    重要句型或語法
    1、現(xiàn)在完成進行時
    該時態(tài)是第二冊區(qū)別與第一冊,新增出來的時態(tài)。主要用來表示過去發(fā)生的動作,持續(xù)到現(xiàn)在,而且還會繼續(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具有兩個不同形式的副詞,而且含義不一樣。比如:形容詞deep有兩個副詞,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. (這個洞穴很深。)
    They are deep in love with each other.(他倆相互深愛著對方。)
    課文主要語言點
    We have just moved into a new house and I have been working hard all morning. 1)本句話是對比現(xiàn)在完成時和現(xiàn)在完成進行時的典型例子。前半句用了現(xiàn)在完成時,因為要表達的是剛剛搬進了新家,而后半句用了現(xiàn)在完成進行時,是因為要表達整個上午一直都在忙著。 2)move into...,搬進某處。注意與move in(搬進,不及物,后面不接賓語)和move to...(搬到某地,是較大的地點名稱)的區(qū)別。 3)hard,努力地,是個副詞。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,整個上午,相當于all the morning。注意“all+時間”表示持續(xù)的一段時間,是進行時的標志。
    I have been trying to get my new room in order. 1)本句話之所以也采用了現(xiàn)在完成進行時,是因為這句話時緊接著上句話中所說的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,因為該句要表達的是要做好這件事情不容易的客觀事實。 2)own,擁有。該詞也可以用作形容詞,表示“自己的”。其常用的短語是:on one's own,獨自、獨立。
    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,表示“更糟糕的是...” 2)rather,非常、相當。該詞一般用來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,該詞主要用來修飾褒義的或是積極的形容詞或副詞。 3)temporarily,暫時地、臨時地。源自形容詞temporary(暫時的、臨時的)。
    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。相當于now。 2)cover,占據(jù)、覆蓋。 3)every inch of+地點,表示“某個地方全是...” 4)space,空間。 5)actually,實際上。源自形容詞actual(實際上的)。
    A short while ago, my sister helped me to carry one of my old bookcases up the stairs. 1)a short while,一會兒。while相當于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起強調(diào)作用。
    This is the prettiest carpet I have ever seen,' she said. 1)This is the+高級+名詞+sb. has/have ever done,表示“這是某人見過的或做過的...的...”。名詞后面省略了關系代詞that。 2)carpet,地毯(用來踩的)。注意與blanket(毛毯,用來蓋的)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。相當于stare at。 2)句中的then added前面好加上and。add,補充道、接著說。 3)not...at all,根本不、一點也不。 4)in one's spare time,在業(yè)余時間。 5)read the carpet,此處的carpet指的是作者的over a thousand books。

    重要句型或語法
    時態(tài)復習
    本課主要對比復習一般過去時、現(xiàn)在完成時和現(xiàn)在完成進行時的用法。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.
    課文主要語言點
    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。這是完成時的標志性時間狀語。 2)本句的謂語動詞try采用了現(xiàn)在完成進行時,說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。注意雖然這句話時問句,但因為被用作了從句,所以要恢復正常語序。此外,要注意begin用了一般過去時,是因為作者想表達的意思是:火在過去是怎么燒起來的。
    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,是因為在闡述客觀事實。 2)which引導的是限定性定語從句,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。其動作名詞為examination,可簡寫為exam;表人的名詞為examiner。 2)注意but后面省略了they,因為前后主語是一致的。
    They were also quite sure that a cigarette end did not start the fire. 1)be sure of/about sth.,對...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,后面要用逗號隔開;在句中時,前后都要用逗號隔開;在句末時,前面要用逗號隔開。 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。注意該詞的構詞方式為:dis-+cover,其中的c在發(fā)音時要濁化為[g]。其名詞形式為discovery。 4)cause,起因。該詞可以用作動詞,表示“導致”。
    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引導的是限定性定語從句,修飾先行詞a snake。 4)wind round,纏繞在...上。注意wind在此用作動詞,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詞的wind,其過去式為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,通過這個辦法。 2)be able to,好不容易得以、能夠。 3)solve the mystery,解決謎團。
    The explanation was simple but very unusual. 1)explanation,解釋。源自動詞explain。 2)simple,簡單的。注意與easy的區(qū)別:simple側重事情顯而易見,不難懂;而easy側重事情的難度小,容易做。 3)unusual,不尋常的。源自usual。
    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。注意其過去式要雙寫p。 3)wind oneself round,纏繞在...上面。
    When it did so, it sent sparks down to the ground and these immediately started a fire. 1)注意句中的did so是指前文的wound itself round the wires。 2)spark,電火花。 3)start a fire,引起火災。

    本課繼續(xù)學習冠詞的用法。本課側重的是定冠詞the的用法:
    1)定冠詞+形容詞,表示一類人或物;
    2)“定冠詞+名詞”與不加定冠詞的區(qū)別;

    2、some與any
    本課側重的是some與any修飾不可數(shù)名詞時的用法,主要對比的是一般疑問句和肯定句中的用法。如:
    Did you do any work yesterday? I did some work before breakfast.
    課文主要語言點
    After breakfast, I sent the children to school and then I went to the shops. 1)注意對比sent the children to school(school前不用任何冠詞)和went to the shops(shops前加了定冠詞)的區(qū)別。 2)send sb. to somwhere,送某人去某處。 3)go to the shops,固定短語,去購物。
    It was still early when I returned home. 注意home的短語用法,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. So I decided to make some meat pies. 1)注意本句話采用排比句式,都是主系表結構,具有一定的強調(diào)效果。 2)be at school,上學。be at work,工作。注意school和work前面都不加任何冠詞。 3)quiet,安靜的。注意拼寫,不要跟quite(非常,很)混淆了。 4)decide to do sth.,決定、決心做某事。
    In a short time I was busy mixing butter and flour and my hands were soon covered with sticky pastry. 1)in a short time,很快。注意“in+一段時間”一般都表示將來時間。 2)be busy doing,忙于做某事。 3)be covered with,覆蓋著、滿是。 4)sticky,粘的。源自動詞stick(附著)。
    At exactly that moment, the telephone rang. Nothing could have been more annoying. 1)at exactly that moment,就在那時。exactly,正是、就是。 2)注意比較級的否定結構其實表達的是高級。本句話Nothing could have been more annoying可以作為常用句型來用。當我們要表達對過去事情的性質(zhì)評論時,就可以用Nothing could have been more ...來表達。 3)annoying,令人惱火的。源自動詞annoy(使惱火)。
    I picked up the receiver between two sticky fingers and was dismayed when I recognized the voice of Helen Bates. 1)pick up,拿起。注意該短語還可以表達“養(yǎng)成;習得;用車載”等意思。 2)receiver,聽筒。 3)dismayed,感到沮喪的、失望的。 4)recognize,意識到、辨認出。注意該詞的重音在第一個音節(jié)。
    It took me ten minutes to persuade her to ring back later.

    What a mess! There was pastry on my fingers, on the telephone, and on the doorknobs. 1)What a mess!,感嘆句,意思為“多亂啊!)。相當于How messy! 2)doorknob,球形門把手。
    I had no sooner got back to hte kitchen than the doorbell rang loud enough to wake the dead. 1)no sooner...than...一...就...。注意該句型一般都用來描述過去發(fā)生的事情,no sooner所在的主句動作采用過去完成時,而than引導的從句動作則采用一般過去時。該句型相當于hardly...when...。 2)loud enough to wake the dead,響聲足以把死人吵醒??勺鳛楣潭ň湫?,用來表達聲音之大。
    This time it was the postman and he wanted me to sign for a registered letter! 1)it was the postman:當我們不知道對方是誰的時候,經(jīng)常用it來指代。 2)sign for sth.,簽收某物。 3)a registered letter,掛號信。
