【文章內(nèi)容簡介】 op is.［析］ 在用名詞作修飾詞來修飾另一名詞時，這個作修飾詞的名詞應用單數(shù)形式，如：a shoe shop 鞋店 a fruit shop 水果店 a book shop 書店a post office 郵局 a police station 警察局 a bus stop 汽車站［誤］ He is weak at physics.［正］ He is weak in physics.［析］ 在表達擅長于作某事時用be good at something, 而其反意詞為be bad at something， 但be weak in something。［誤］ This dictionary is worth to buy.［正］ This dictionary is worth buying.［析］ be worth 后可接動、名詞表達值得作某事，又可接價格、金錢表示值多少錢。［誤］ Don39。t afraid of that.［正］ Don39。t be afraid of that.［析］ afraid 在英文中是形容詞而不是動詞。這樣的詞組還有：be afraid of 害怕 be careful of 小心be certain of 有把握，確定 be sure of 確信be glad of 高興 be sick of 厭惡be fond of 喜歡［誤］ The work has already been done well.［正］ The work has already been well done.［析］ well 與badly作副詞時，表示好壞，如果句子是被動語態(tài)，則應放在過去分詞之前，如：This machine has been badly damaged. 如果句子是主動語態(tài)，則應放于句末，如：I did my homework well.［誤］ We are yet in the classroom now.［正］ We are already in the classroom now.［析］ already主要用于肯定句，而yet多用于否定句和疑問句中，如：Did you finish it? No. not yet.［誤］ Look. Here es he!［正］ Look! Here he es!［誤］ Look! Here the bus es!［正］ Look! Here es the bus!［析］ 在句子開頭用Here時，如主語是人稱代詞則不要用倒裝語序，如果主語是名詞則要用倒裝語序。［誤］ She is my older sister.［正］ She is my elder sister.［析］ elder 和eldest是用來指家庭中兄弟姐妹的長幼關系，而older, oldest 則是指歲數(shù)大多少，如：She is three years older than I.［誤］ I39。m tired. I can39。t go further.［正］ I39。m tired. I can39。t go farther.［析］ far有兩個比較級 farther 較遠的，further 進一步的，如：Do you need any further explanation? 你需要進一步的解釋嗎?當然它也有兩個最高級。farthest和furthest.［誤］ I went to Beijing University five years before.［正］ I went to Beijing University five years ago.［析］ ago常與過去時連用，而before則多與完成時連用。［誤］ Have you finished your homework? No, not already. ［正］ Have you finished your homework? No, not yet. ［析］ 仍然有三個英文字可以表達它們是already， yet 與 still。 要注意的是 already經(jīng)常用于肯定句中，如The bus has already gone。 而yet 多用于疑問句和否定句中，如：Have you finished your homework yet? 而still則常用于主語與謂語動詞之間，如：We still can39。t decide what to do. 但也有時用于be 動詞之后，如：He is still here.［誤］ He is very higher than I am.［正］ He is much higher than I am.［析］ much可以用來修飾比較級，而very則用來修飾形容詞原級，如：I39。m very tired.［誤］ Can I walk to the station? You39。d better not.

Yes I think so, /I hope so, /I believe so/ I39。m afraid ，英語口語的習慣用法則有所不同，如，I don39。t think so 而在hope, belive 與 afraid后則常用not， 如：I hope not.［誤］ She didn39。t work enough hard, so she couldn39。t pass the exam.［正］ She didn39。t work hard enough, so she couldn39。t pass the exam.［析］ enough 可以作名詞用，如：Enough has been said for how to learn English well. (對于如何學好英語已經(jīng)講的足夠多了。)另外它可以作為形容詞，如：I have enough money (or money enough) to buy this dictionary. 注意 enough作為形容詞時即可放于名詞前又可放于名詞后，在初中范圍的考題中多用于名詞之前。如果enough 作為副詞用，那么它一定要放在被修飾的形容詞或副詞之后。［誤］ You can39。t be very careful.［正］ You can39。t be too careful.［析］ 此句話的含意是你如何小心也不過分。too…to的用法是太……以至于不能作某事。但在實際應用時也常常將后面的to省去，如：It is too expensive for 。［誤］ He is good past fifty.［正］ He is well past fifty.［析］ well 作為副詞用時除用于好之外還有大大地、遠遠地，等意。往往有人對下面兩句的對或錯有爭議；He is well.He is good.其實這兩句都是正確的表達法，只不過其含意不同。He is well是他身體不錯，而He is good 則為他是個好人。［誤］ She is not as half clever as her brother.［正］ She is not half as clever as her brother.［析］ 在as…as結(jié)構(gòu)中要將修飾形容詞的數(shù)量詞倍數(shù)及nearly, almost, exactly… 等置于第一個as之前。［誤］ He is same age as Tom.［正］ He is the same age as Tom.［析］ the same…as是固定的用法，其中定冠詞the是不可省也不能換成別的詞的。［誤］ Mother and her daughter are exactly like.［正］ Mother and her daughter are exactly alike.* like 作為介詞，其意為像，應用于 look like, be like, sound like, 其后要加賓語。而 alike 是形容詞，或副詞，如: You and I think alike. The twins are dressed alike。 但 alike 僅作表語而不能用于名詞前作定語。［誤］ Who is taller of the two?［正］ Who is the taller of the two?［析］ 兩者的比較級之前要加定冠詞。［誤］ I have less books than Tom.［正］ I have fewer books than Tom.［析］ less 是 little的比較級，而fewer是few的比較級。less后應加不可數(shù)名詞而fewer后是可數(shù)名詞。［誤］ There are three girls in my group. The cleverer is Mary.［正］ There are three girls in my group. The cleverest is Mary.［析］ 在兩者之間應用比較級，在三者之間或三者以上的范圍內(nèi)應用最高級。［誤］ The boy sat there as quiet as his sister.［正］ The boy sat there as quietly as his sister.［析］ as…as的用法要注意的是：①在其中間應加形容詞或副詞的原級，而不可加比較級，也有的語法書中稱為同級比較。②要
