1.冬天很寒冷。
It's very cold in the winter. 錯誤
It's very cold in winter.正確
泛指冬天時，winter前面一般不加冠詞。同樣，「在春天」應說in spring，「在夏天」應說in summer，「在秋天」in autumn是 。有時四季前面有關係代詞修飾或特定指示的對象時，也與定冠詞連用。如：Fruit must be picked in the autumn. 必須在秋天摘水果。
2.你會踢足球嗎？
Can you play the football? 錯誤
Can you play footballs? 錯誤
Can you play football? 正確
踢足球應說play footbal，這裡football作「足球運動」解，是不可數名詞，前面不用冠詞，也不用複數形式。同樣，「打籃球」應說play basketball，打排球應說play volleyball，打桌球應說play ping pong/table tennis

In the Northwest, there will be snow in night.錯誤
In the Northwest, there will be snow in the night.正確

7.不要躺著看書，這對你的眼睛是有害的。
Don't read in the bed, it's bad for your eyes.錯誤
Don't read on the bed, it's bad for your eyes.錯誤
Don't read in bed, it's bad for your eyes.正確

8.我想我（患）感冒了。
I think I've had cold. / I think I've taken a cold.錯誤
I think I've caught cold / caught a cold / got a cold.正確
「患感冒」在英語中可以說catch / get (a) cold have a cold（a一定不可省去 。但應注意的是，如cold前有形容詞修飾時，不論cold與哪一個動詞搭配，都要與冠詞 a連用。She has caught a very bad cold.她患了重感冒。（此時冠詞a不可省略）

14.我想買半公斤肉。
I want to buy half kilo of meat. 錯誤
I want to buy a half kilo of meat.正確

17.她通常在晚飯後看半小時的電視。
She usually watches TV for half an hour after the supper.錯誤
She usually watches TV for half an hour after supper.正確

After a quick breakfast, she hurried to school.她很快地吃完早飯後就急急忙忙去上學了。

It's very a nice horse.錯誤
It's a very nice horse.正確
It's quite a nice horse.正確

19."a number of" 和 " the number of "有什麼區別?
a number of的意思是「許多」 「若干」，後接可數名詞的複數形式

The number of students in our class is fifty. 我們班的學生人數是50名。
20.序數詞前常與定冠詞 the連用，但有時也與不定冠詞a(an) 連用，它們有什麼區別？
序數詞前用the 側重順序，序數詞前用 a (an)不側重順序，表示「再一」「又一」的意思，例如：There’s a third boy. He’s very tall. 又有一個男孩（前面已出現兩個男孩），他個子很高。
Mr. and Mrs. Shute had a daughter called Jane. Then they had a second child－a son.舒特夫婦有一個女兒叫珍。後來他們又有了一個孩子──兒子。
21. on the earth 和 on earth 有什麼區別？
on the earth的意思是「在地球上」 on earth 的意思是「在世上」，相當於in the world，另外on earth還可作「究竟」 「到底」 「全然」解，多用於疑問句，否定句或最高級後面加強語氣。例如
That means that in about 600 years, there will only be standing room on the earth.
