高中生寫作文容易犯的錯誤
有很多同學會在寫作的過程當中經常暴露一些弱點、犯一些錯誤，小編今天整理了同學們對英語作文中的常見錯誤按語法類別進行歸納，並舉以實例，希望同學們能夠由此發現自己的問題並及時改正
名詞性從句
are talking about if this plan should be carried out.
If 和whether都可以引導動詞的賓語從句，如果從句做的是介詞賓語，只能用whether引導。所以把if 改爲whether。
70.I can not decide if to stay or not.
只有whether才能和不定式搭配使用。因此把if 改爲whether。
suggestion is we try for a second time.
表語從句的引導詞如爲that，一般不省略。因此在we前加上that。
will the professor say is not known yet.
名詞性從句的語序都是陳述句語序。因此應改爲：What the professor will say is not known yet.
狀語從句
73.I will go unless he invites me.
此句意爲“除非他邀請我，否則我不去。”而unless相當於if not, 所以本句應改成：I won’t go unless he invites me。
ough he tried, but he still couldn’t keep up with the others.
although 和but 不能同時用在一句話中，去掉任何一個都可以。
75.I won’t stay until he comes back.
含有not…until的句子的謂語動詞應是點動詞，含有until的肯定句的動詞應是延續性動詞，此句有兩種改法：I will stay until he comes back.或I won’t leave until he comes back.
定語從句
orphan is a child who’s parents are dead.
定語從句中表“…的”引導詞只有whose，所以把who’s 改爲whose。
is the very thing which I lost yesterday.
如果先行詞爲物且前有the only, the last, the very修飾時，定語從句的引導詞只能用that。
is the car for that I paid a high price.
定語從句的先行詞爲物，而且引導詞放在介詞後時，只能用which.
is one of the students who has passed the exam.
定語從句修飾one of 加上覆數名詞時，複數名詞是定語從句的先行詞，因此把 has 改爲have。
is the place where we visited last year.
定語從句的先行詞用關係代詞還是關係副詞要看定語從句中缺不缺主語或賓語，如缺用關係代詞，如不缺用關係副詞。此句中visit爲及物動詞，後無賓語，因此把where 改爲which或that。
81.I, who is your friend, can understand you.
定語從句的謂語動詞應與其先行詞保持一致，因此把is 改爲am。
a is a developing country, that is known to all.
非限定性定語從句的引導詞永遠不會是that，因此把that 改爲which 或as。
主謂一致
poet and writer are invited to give a speech at the meeting.
poet和writer共用一個冠詞，指的是一個人身兼二職，所以謂語動詞應爲單數。把are改爲is.
one except my parents know it.
主語後加except再加上若干數量的名詞，謂語動詞和主語保持一致。所以把know改爲knows。類似的用法的詞或短語有：but, besides, with, together with, along with, as well as等等。
clothes is on the table over there.
clothes爲複數句詞，謂語動詞應爲複數。把is改爲are。
number of the students in that school are about one thousand.
此名的主語爲number而不是students。因此把are 改爲is。
class was watching TV when I entered the room.
class作主語時，把它看成一個整體時謂語動詞用單數，看成每一個成員的個體行爲時謂語動詞用複數。一般來說，一些具體行爲如看電視、吃飯、洗澡等都屬於每一個成員的個體行爲。此處把was改爲were。
population of our country are increasing slowly now.
population 單獨作主語謂語動詞經常用單數;如果其前有分數或百分數，而且後面又有複數名詞時謂語動詞用複數。如：One fifth of the Chinese population are workers. 此處把are改爲is。
倒裝
sooner he had reached the station than the train left.
no sooner 爲否定副詞，放於句首時句子要部分倒裝，因此此句應改爲：No sooner had he reached the station than the train left.
comes he.
here 放於句首時，句子主謂要完全倒裝，但句子主語爲代詞時，則主謂不倒裝。此句應改爲：Here he comes.
91.A child as he is, he can speak five languages.
用as引導讓步狀語從句，可把形容詞、副詞和不帶冠詞的名詞放於as前。所以前半句改爲：Child as he is...
虛擬語氣
would have come if we invited her.
這是與過去事實相反的虛擬假設，從句應該用過去完成時。所以在 we 後加 had.
suggestion is that we would send a few people to help them.
suggestion 的表語從句也應用虛擬語氣，必須用should加動詞原形，should可以省略。此處去掉would 或把would 改爲should。
secretary wishes that she has time to type the letter now.
wish 後的時態應該把真實時態往後推一個時態，所以把has改爲had。
’s time that we go to bed.
句式爲It’s time sb did sth 所以把 go 改爲 went。
96.I would rather you have another try tomorrow.
詞組爲would rather sb did sth. 所以把have改爲had。
there be句式
e are a bag and several books on the table.
There be 句式遵循謂語動詞就近原則，a bag爲單數，所以把are改爲is。
e were several people stood at the back of the room.
There be句式的謂語動詞爲be動詞，句中其他的動詞應爲非謂語動詞。所以把stood改爲standing.
修飾語在句中的位置不當
almost have written twenty compositions this term.
像almost這樣的副詞在句中放在助動詞、be動詞之後，實意動詞之前。因此把almost放在have後面。
girl has beautiful, silky hair who lives high in the mountains.
定語從句應緊跟先行詞，所以改爲：The girl, who lives high in the mountains, has beautiful, silky hair.
