英語寫作最易犯的錯誤
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
寫作中，學生們常把握不好名詞的數、所有格以及一些集合名詞的用法。
1. He gave me a very good advice yesterday.
句中的a要去掉，因爲advice是不可數名詞。一些漢語概念爲可數的詞在英語中卻是不可數的，表示數量時在其前加a piece of，類似的詞有：news, bread, work, paper, chalk, furniture, information等等。
2. That girl loves reading book.
可數名詞單數不能孤零零地放在句子裏，或前面加冠詞，或將其變爲複數。此處最好變爲books.
3. He went into a book’s shop and bought a dictionary.
一般表示有生命的東西的名詞的所有格用’s，如my mother’s car, 而此處適宜用名詞修飾名詞，改爲a book shop.
4. My family is watching TV.
一些集合名詞如看成一個整體，則用單數的謂語動詞，如My family is a happy one; 如強調集合中每個個體的個人行爲，則用複數的謂語動詞。此處看電視是個體行爲，應把is改爲are。類似的詞有：team, class, audience等。
5. I bought some potatos and tomatos at the supermarket.
中學階段以“o”結尾的名詞中有四個詞變複數時要加es，它們是tomato, potato, Negro, hero; 其餘的都加s變爲複數。
has nothing to do with their believes.(這和他們的信仰沒關係。)
以f, fe 結尾的詞變爲複數時一般去f, fe 加ves，如knife—knives, thief—thieves; 而roof 和belief直接加s變爲複數。所以應把believes改爲beliefs.
冠詞
7. The boss wants to hire an useful person.
用a還是an，取決於後面單詞的第一個音標，如爲元音用an，爲輔音用a。useful的第一個音是輔音所以應把an改爲a。類似的，我們說a European country.
e is a machine that can fly.
Plane爲可數名詞單數，不能單獨放在句中，應在其前加冠詞或把它變爲複數，而本句後有a machine, 因此只能在其前面加a，變爲A plane。
played a piano at the party yesterday.
把a 改爲the ，因爲樂器前用定冠詞。
machine was invented in 1920s.
在in後加the，因爲表示年代用in加the再加幾十的複數，如在八十年代in the 80s。
Hong went to school by the bus every day.
去掉the，因爲表示交通方式用by直接加交通工具。
代詞
使用代詞時請注意其單、複數，主、賓格以及形容詞性物主代詞和名詞性物主代詞的用法。
is one of those speakers who make his ideas perfectly clear.
定語從句的先行詞是those speakers，爲複數，因此從句中的指示代詞應爲複數，應把his改爲their。
13. Whom do you think has left the lights on?
放在疑問句特殊疑問詞後的do you think / believe / guess / imagine / suppose等都不參與句子成分，把它們去掉後，疑問詞在句中做主語用主格，做賓語用賓格。本句中去掉do you think後缺的是主語，應把Whom改爲Who。
boss pretended not to see John and I.
John和I在句中都做的賓語，應把I 改爲me。
e books are mine; those in the bag are her.
Her是形容詞性物主代詞，後面應該加名詞books，或把her 改爲hers。
數詞
e are fourteen hundreds students in our school.
Hundred / thousand / million / score/ dozen等詞前有具體數字時後不加s，前面沒有具體數字時在其後加s 和of，表示大約幾百幾千的概念。如 two hundred students(兩百個學生)，hundreds of students(成百上千個學生)。例句中應把hundreds 改爲hundred。
r school is twice as larger as our school.
表倍數關係的as---as中間只能用形容詞或副詞的原級。因此把larger改爲large.
y’s homework is a five-hundred-words composition.
幾個單詞由連字符連接而組成的複合形容詞中的名詞只能用單數，所以把five-hundred-words改爲five-hundred-word.
third of the students in our school are from America.
英語表達中分數的分子用基數詞，分母用序數詞，分子大於一時分母后要加s，所以就把third 改爲thirds.
形容詞和副詞
形容詞和副詞容易被誤用，形容詞和副詞的比較級和最高級也是應注意的重點。
patient appeared nervously when he talked to the doctor.
appear在此是個系動詞，其後應接形容詞作表語。所以把nervously改爲nervous.
artist worked hardly to finish his drawings on time.
此句需要一個副詞來修飾，hardly是副詞，但意爲“幾乎不”，hard 也可以是副詞，表努力，因此把 hardly 改爲hard.
shirt is more cheaper than that one.
More只構成比較級，而不能修飾比較級。因此把more去掉。
is the most successful of the two businessmen.
兩者相比較時，比較級前用定冠詞，三者或三者以上才用most，因此把most改爲more.
works less harder than he used to.
表不如… 時用less加上形容詞和副詞的原級，因此把harder改爲hard.
book is fairly more interesting than that one.
fairly只能修飾形容詞和副詞的原級，可以修飾比較級的副詞或短語有：much, even, still, far, a lot, a little, a bit, any, no, by far, rather等，因此把fairly改爲rather.
is as an interesting a story as the one in the magazine.
as … as中間的詞序是as加上形容詞加上a(n)加上名詞再加上as，因此應改爲as interesting a story as the one.
weather here is nicer than Xizang.
同樣的事物才能相比較，weather和Xizang不具有可比性，因此應改爲The weather here is nicer than that of Xizang.
29.I would rather take a train than went by bus.
這個詞組爲would rather do … than do …，因此把went改爲go.
there interesting anything at the meeting?
修飾anything, something, every-thing, nothing的形容詞都要放在它們的後面。
31.I never have seen such a person before.
像never之類的副詞在句中應放在be動詞、助動詞之後，實意動詞之前。因爲應改爲I have never seen such a person before.
book is worth to be read.
be worth doing 意爲值得被做。因此改爲The book is worth reading.
is sure that he will succeed.
sure 的主語只能爲人，而certain的主語可爲人和物。因此把sure改爲certain.
is regarded as one of the best alive writers at present.
alive 爲表語形容詞，偶爾也做後置定語。因此把alive改爲living，或把alive 放在writers後面。
35.I don’t know that he has finished the work yet.
yet 用於否定和疑問句，already用於肯定句。把yet 改爲already.
said nearly nothing at the meeting.
nearly 不與否定詞用在同一個句子中，而almost可以。因此把nearly 改爲almost.
介詞
usually goes to school by his father’s car.
by加上名詞表示一種交通方式，中間什麼都不加，如by car, by bus, by plane等;如果名詞前有其他的詞修飾，則應除by以外的其他介詞，此處把by改爲in.
se wait me at the school gate.
wait爲不及物動詞，需加介詞for後才能再跟名詞或代詞做賓語。
has been married with Betty for more than twenty years.
marry不跟 with連用，應把with改爲to。
40.I finished the work on time under the help of him.
“在…的幫助下”用with而不用under。
