1)all與 whole都可以和單數(shù)名詞連用。例如:

火眼金睛:
1.可能不可能:
maybe與may be用法的區(qū)別:
(一) ①may 是一個(gè)情態(tài)動(dòng)詞,,后面接動(dòng)詞原形,,表示推測(cè),有“可能,;或許”的意思,。如:She may go to school this afternoon.今天下午她或許去上學(xué)。
②maybe 是一個(gè)副詞,,意為“大概,;也許”相當(dāng)于perhaps,通常用于句首,,有 時(shí)也放在句中或句末,在句中作狀語(yǔ),。如:Maybe he can come.他可能會(huì)來(lái)。
③may和be 如果分開(kāi)寫(xiě),就是情態(tài)動(dòng)詞 may +系動(dòng)詞be,,在句中作謂語(yǔ)動(dòng)詞,,構(gòu)成主系表結(jié)構(gòu),譯為“可能是”,。如:
He may be a student.他可能是一個(gè)學(xué)生,。
(二)比較以下各組句子,含義相同,,但結(jié)構(gòu)不同:
(1)你也許是對(duì)的,。 ①M(fèi)aybe you are right. ②You may be right.
(2)他可能迷路了。 ①M(fèi)aybe he has lost the way.
②He may have lost the way.
③It may be that he has lost the way.
(三)maybe 可單獨(dú)用作答語(yǔ),,但 may be 不能這樣用,。如:
A:Do you think he’ll come back? 你認(rèn)為他會(huì)回來(lái)嗎?
B:Maybe. (Maybe not.) 也許會(huì)回來(lái)吧(也許不會(huì)回來(lái)吧)
2.“試試”行不行:
try作動(dòng)詞時(shí),意為“試圖,,努力,,設(shè)法”。常見(jiàn)結(jié)構(gòu)有:try to do sth.和try doing sth.兩者用法有些差別:
try to do 表面的意思是; 試著做某事,,但實(shí)際上的意思是:努力想做成某事,。
比如,I tried to escape,but I failed. "我努力著想逃走,,但是沒(méi)有成功,。"
而try doing 表面意思也是:試著做某事,但實(shí)際意思是:(為了達(dá)到另外的一個(gè)目的)做某種嘗試看行不行,。 比如,,
----"So hot here,isn't it?"
----"Yes,why not try turning on the air conditioner?"
"很熱,是吧,。" “嗯,,就是。咱們開(kāi)開(kāi)空調(diào)吧,,看看能不能涼快點(diǎn)兒,。”
I tried using English everyday to improve my oral English.
“我每天都說(shuō)英語(yǔ),,看對(duì)我的口語(yǔ)有沒(méi)有一點(diǎn)兒提高,。”
或者“為了提高口語(yǔ)水平,,我每天都說(shuō)英語(yǔ),。”
總之,,一句話,,就是try to do 是那種“全力以赴,,殫精竭慮的干某事”的意思,并且,,似乎一般都是沒(méi)有成功的,,有一種,“本來(lái)很想怎么怎么樣,,可最后白忙一通兒”的這種感覺(jué),。
而try doing是那種“(試著)怎么怎么樣,看看某種方案對(duì)另外一個(gè)結(jié)果有沒(méi)有幫助”的意思,,說(shuō)白了,,只是提出一種方案而已,我感覺(jué)如果你哪怕把try doing 理解成 do,,意思都還基本是一樣的 ,。就像上面那句 :
-------"So hot here,isn't it?"
-------"Yes,why not try turning on the air conditioner?"
也可說(shuō)成: ----"So hot here,isn't it?"
---- Yes,why not turn on the air conditioner?"
3.“今天”無(wú)煩惱:
“What's today?”是問(wèn)星期,、日期,、還是節(jié)日呢?“今天”可有點(diǎn)麻煩啦,!
①What's today,?是問(wèn):“今天是幾月幾號(hào),星期幾,?”答的時(shí)候要先答星期,,再答月份,然后是幾號(hào),,最后才是年份,。例如,可以回答:
It's Monday,January the 18th,2010.今天是星期一,,2010年1月18日。
②問(wèn)日期時(shí)這樣說(shuō):What's today's date? What's the date today?
③問(wèn)星期時(shí)應(yīng)該說(shuō):“What day is it today”或者“What day is it?”
④而What's the day today?是問(wèn)“今天什么節(jié)日,?”回答 節(jié)日,,比如國(guó)慶節(jié) National Day等等
4.“運(yùn)動(dòng)”有規(guī)則:
game,match和sport各行其道
①game主要指決出勝負(fù)的游戲,通常有一套規(guī)則,,凡參加者均要遵守,。
如: Let’s go and watch the football game (match). 咱們?nèi)タ醋闱蛸惏伞?/P>
②在英國(guó)match通常指比賽,而在美國(guó)game通常指比賽,,另外game作復(fù)數(shù)時(shí)一般指大型的國(guó)際體育運(yùn)動(dòng)會(huì),。如: the Olympic Games 奧林匹克運(yùn)動(dòng)會(huì)
③sport多指戶外的游戲或娛樂(lè)活動(dòng),如打球,、跳高,、游泳,、釣魚(yú)、打獵,、賽馬等,。如: Skating is one of the winter sports.
滑冰是冬季運(yùn)動(dòng)中的一個(gè)項(xiàng)目。
sport作復(fù)數(shù)時(shí)可以和meet, day連用,, 指運(yùn)動(dòng)會(huì),。如: sports meet或sports day。
5.花開(kāi)“別”樣紅:
other ,the othe,others,another好像都有“別的”這個(gè)意思,,你能分清嗎,?
(1)another既可作形容詞又可作代詞,泛指“再一個(gè),,又一個(gè)”,,表示“總數(shù)為三個(gè)以上中任意的另一個(gè)”,表示泛指,,可以單獨(dú)使用,。作定語(yǔ)時(shí),修飾可數(shù)名詞單數(shù),,其前不加冠詞,。
This dress is dirty,please change another one for me.
這件裙子臟了,再給我換一件吧,。
(2)the other表示“兩個(gè)數(shù)量中的另一個(gè)”,,表示特指,總數(shù)為倆,;它可以單獨(dú)使用,,也可用the other+可數(shù)名詞單數(shù)。例如;
His parents both work in a hospital. One is a doctor and the other is a nurse.他父母都在一家醫(yī)院工作,。一個(gè)是醫(yī)生,,一個(gè)是護(hù)士。(父母為兩個(gè)人)
(3)others用于泛指一些人或事物中其他的,,可單獨(dú)使用或用other+復(fù)數(shù)可數(shù)名詞來(lái)代替,。注意others后面不可直接加名詞。例如:
①Some students like English and other students (others) like physics.
有些學(xué)生喜歡英語(yǔ),,有些學(xué)生喜歡物理,。
②We must think more of others.
我們必須多想想別人。 (同學(xué)們:這可是好品質(zhì)哦?。?BR style="LINE-HEIGHT: 25px">(4)the others指一定范圍內(nèi)其余所有的人或物,,表示特指。也可用the other+名詞復(fù)數(shù)來(lái)代替,。
This dictionary is better than the others. 這本詞典比別[其余]的好,。
【補(bǔ)充】else adv.別的. (用于疑問(wèn)詞,、不定代詞后)其他,另外
I'm going to take you somewhere else. 我要帶你去別處。

(1)have to 與動(dòng)詞原形一起構(gòu)成謂語(yǔ),它可用于多種時(shí)態(tài),,有人稱和數(shù)的變化,。在一般現(xiàn)在時(shí)中,當(dāng)主語(yǔ)是第三人稱單數(shù)時(shí),,要用has to,其余人稱用have to;一般過(guò)去時(shí)中用had to;一般將來(lái)時(shí)中用will have to.

他說(shuō)他們必須努力工作,。(主觀上要做這件事)
② have to有人稱、數(shù),、時(shí)態(tài)的變化,,而must只有一種形式。但must 可用于間接引語(yǔ)中表示過(guò)去的必要或義務(wù),。
He had to look after his sister yesterday.His parents were out.
③ 在否定結(jié)構(gòu)中: don't have to 表示"不必",; mustn't 表示"禁止"。

(二)情態(tài)動(dòng)詞can的用法:
情態(tài)動(dòng)詞can 的過(guò)去式為could ,(有時(shí)could表示更委婉的語(yǔ)氣,。)
①表示能力,、功能等:“ 能,能夠,,會(huì)”:
例句: We can and must overcome our shortcomings.
我們能夠而且必須克服我們的缺點(diǎn),。
②表示可能性: “可能;可以,;會(huì)”:
例句: In winter the winds can be very cold.
冬天的風(fēng)會(huì)很冷的,。
③表示從內(nèi)心里可以接受: “可以,能夠”
例句: I can regard you as my brother but you must obey what I tell you .
我可以把你看做我的兄弟,,但是你必須聽(tīng)我的話,。
④表示請(qǐng)求、要求,、建議等: “可以”:
例句: Can you help me to carry these books to the classroom?
你能不能幫我把這些書(shū)送到教室去?
⑤表示允許等: “可以”:
例句: You can have my seat.I'm going now.
你可坐在我的座位上,,我現(xiàn)在就走。
【注意】can表示能力可和be able to互換使用,,且后者有更多的時(shí)態(tài),,be able to常被用來(lái)表示can所不能表示的將來(lái)或完成時(shí)的概念,。
典例剖析:
1.I'm trying_______ it better.
A.to do B.doing C.did D.does
【剖析】本題考查try的結(jié)構(gòu)用法。try to do sth.意為“盡力做某事”,,try doing sth.意為“試著做某事”,,由題意“我想盡力把它做得更好?!笨芍鸢高xA.
2. The work is too difficult for Mr Zhu to finish in a week. He needs _________ days.
A.more two B .two more C. two another D.another more
【剖析】本題考查more,another與數(shù)字的連用,。數(shù)字后加more意為“額外再……”
本句意為“他需要另外兩天?!?,,故答案選B. 注意:本空如果填another two亦可。
3.——Could I have a look at the photo of your family?
——Of course you _______ .
A.may B.can C.could D.couldn't
【剖析】本題考查can與could的用法,。Could I…?是請(qǐng)求別人許可時(shí)常用的句型,,肯定回答用Yes/Of course/Sure,you can,但不可用could回答,因?yàn)閏ould在此句型中是一種委婉的語(yǔ)氣,,而不是can的過(guò)去式,。故答案選B.
