【正文】 ，而right now只能用于現(xiàn)在的狀態(tài)。just則用于完成時態(tài)，如： I have just finished my homework.［誤］ My father will be back from America at present.［正］ My father will be back from America presently.［析］ presently有兩個意思：其一是最近，不久，其二在美語中是現(xiàn)在之意，與at present相同。而for the present為暫時，如： I teach English in the school for the present.［誤］ I39。ll be back at the moment.［正］ I39。ll be back in a moment.［析］ at the moment 其意為現(xiàn)在，當(dāng)時，而in a moment意為馬上過一會，與in a minute意思相近。［誤］ The train from Shanghai will arrive here in time.［正］ The train from Shanghai will arrive here on time.［析］ on time為準(zhǔn)時，而in time有兩個含意。其一是及時，如：The doctor arrived in time。其二是將來，終究。［誤］ I met an old friend sometimes last month.［正］ I met an old friend sometime last month.［析］ Sometime 過去，或者將來某時。Sometimes 有時如： Sometimes I go to school by bus.Some time 一些時間 如： I need sometime to do my homework. Some times 幾次 如： I went to Shanghai sometimes this month.at times 有時，偶爾at all times 經(jīng)常some other time 改天 ［誤］ I had met an old friend three days ago.［正］ I had met an old friend three days before.［正］ I met an old friend three days ago.* ago 用在時間狀語中時，主句中謂語動詞一般用過去時，而before用于時間狀語時則主句的謂語動詞宜用完成時態(tài)。［誤］ He studied very hard. and at the end he passed the exam.［正］ He studied very hard, and in the end he passed the exam.［析］ in the end＝at last 意為最終，終于，表達(dá)經(jīng)過若干努力而達(dá)到的結(jié)果。而at the end是在某事的結(jié)束時如何如何，如：At the end of class, the teacher gave us some story books。［誤］ I will e here to help you each three days.［正］ I will e here to help you every three days.［析］ every three days 為每三天，即每隔二天，而every other day為每隔一天。［誤］ He didn39。t go to the cinema yesterday. and I didn39。t go, too.［正］ He didn39。t go to the cinema yesterday and I didn39。t go either.［析］ 英語中表示也，有4個字，also, as well, too, either，但either用于否定句中，而前3個用于肯定句中。在肯定句中too與as well一般要用在句尾，而also則可用于句中。如：She went to the party and her boy friend went there too. 又如： I39。ve also read her other novels.［誤］ We should help the poor girl in anyway.［正］ We should help the poor girl in any way.［析］ anyway為不管怎么講，無論如何，如：What a terrible accident, anyway no one was hurt.any way 為任何方式。這種常見的錯誤還發(fā)生在以下幾組詞中，如：everyday 日常的 every day 每天faraway 遙遠(yuǎn)的 far away 遠(yuǎn)離altogether 總計 all together 一塊，大家一起already 已經(jīng) all ready 全準(zhǔn)備好了［誤］ You can e to the doctor39。s at anytime.［正］ You can e to the doctor39。s at any time.［析］ anytime 是副詞 而any time中的time是名詞。［誤］ She said nearly nothing.［正］ She said almost nothing.［析］ nearly 與 almost的含意相近，在很多場合可以互換，但在否定詞前用almost。［誤］ There are too much mistakes in your homework.［正］ There are too many mistakes in your homework.［析］ too much 后接不可數(shù)名詞，如：There is too much water for the flowers. 而too many 后加可數(shù)名詞，much too 后面加形容詞，如：It is much too difficult to learn English well.［誤］ It is late enough that we can go home now.［正］ It is late enough for us to go home now.［析］ 要注意的是enough后面一般不接從句而接不定式，或不定式的復(fù)合結(jié)構(gòu)：for somebody to do something。［誤］ The twins are very alike.［正］ The twins are much alike.［析］ 用a為首字母的形容詞不能用very修飾，一般要用much來修飾。［誤］ How long does he write to his parents? Once a week. ［正］ How often does he write to his parents? Once a week. ［析］ 英文與中文表達(dá)法不同，隔多長時間辦一次某事，實際上問的是該事發(fā)生的頻率，所以要用how often。［誤］ As soon as I arrive in New York, I39。ll call up you.［正］ As soon as I arrive in New York, I39。ll call you up.［析］ 當(dāng)動詞詞組的賓語是人稱代詞時則一定要放于動詞之后，如果是名詞則可以放在詞組其后。如：I want to watch TV. Please turn on the TV. 也可以講： Please turn the TV on.［誤］ He drove quickly his new car.［正］ He drove his new car quickly.［析］ 副詞在句中的位置很活，但主要有以下幾種用法：①實意動詞之前，如：He quickly give me the answer. ② 在be動詞之后，如：The little boy is often late for class. ③ 第一助動詞之后，如：This book has almost been finished. ④ 在單獨(dú)使用的be動詞和助動詞之前，如： Can you help me this afternoon? I certainly can.但是無論如何也不能將副詞置于動詞與賓語之間，如果是賓語從句或是很長的名詞詞組作賓語則才可以這樣用：He heard clearly what the teacher said.［誤］ The children came late yesterday to the cinema.［正］ The children came late to the cinema yesterday.［析］ 表示一定長度的時間的副詞不應(yīng)放于句中，可放于句尾。如果表示強(qiáng)調(diào)則可放于句首。［誤］ You have few new books, haven39。t you?［正］ you have few new books, have you?［析］ 英語中的數(shù)量形容詞有兩組。修飾可數(shù)名詞的有few(很少，幾乎沒有)，a few(有一些，幾個)；修飾不可數(shù)名詞的有l(wèi)ittle (很少，幾乎沒有)，a little(有一點(diǎn)，有一些)。要注意的是當(dāng)few和little用于句中時應(yīng)看作否定句，而 a few 和a little 用于句中時則應(yīng)看作是肯定句。
［誤］ He spent quite little money on his food.［正］ He spent quite a little money on his food.［析］ quite a 為一固定用法，其意為十分，相當(dāng)，所以。 quite a few＝many, quite a little＝much 而only a little＝little, only a few=few.［誤］ Do you want to have many bread?［正］ Do you want to have some bread?［析］ some與any都可以用作形容詞、副詞或代詞，在一般情況下，some用于肯定句，any用于疑問句和否定句，但在希望得到肯定答復(fù)時，應(yīng)用some。 其次是some 可以用來修飾可數(shù)名詞和不可數(shù)名詞。［誤］ Please tell me where the shoes shop is?［正］ Please tell me where the shoe sh
