　　初二英語必備知識點：定冠詞的常見用法

　　定冠詞也出現在其他11種情況中，非同時注意不可。

　　⑴用在單數名詞前面，以代表同類的人或物，如：

　　The ox is a useful animal for farmers.

　　This type of work is easier for the teacher than for the student.

　　但當涉及 man 和 woman 這兩個名詞時，一般上不必用 the ：

　　Man is mortal.

　　Woman differs from man in many ways.

　　⑵用在單數名詞前面來表示有關名詞的抽象概念，如：

　　Don't play the fool.

　　Peter is fond of the bottle.

　　⑶用在數目字前面，如：

　　Mr Li is somewhere in the 30s.

　　She was not yet born in the 50s.

　　⑷用在測量單位前面，以表示“每”(each/per)，如：

　　Some factory workers are paid by the hour.

　　This car usually does 15 kilometres to the litre.

　　⑸用在比較級形容詞或副詞之前，以加強其意義，如：

　　The teacher explained the idea again, but his students were none the wiser.

　　Your mind will function all the better if you have some time away from your work.

　　初二英語必備知識點：疑問附加語isn't it

　　"John is smart, isn't it?"

　　這個疑問句里的附加語(question tag)對嗎?如果是不對的話，錯在哪里?

　　在公共場所或辦公室里，只要稍為留心，不難聽到“ isn't it ? ”這個附加語。這種疑問句是英文幾種疑問句中的一種，主要的用途在強制答話人提供問話人心目中的答案。

　　這個疑問句有一定的格式，即：

　　·肯定敘述句(affirmative statement)+否定附加語(見例 ①及②)

　　·否定敘述句(negative statement)+肯定附加語(見例③及 ④)

　　①Mary is happy, isn't she?

　　②They will come, won't they?

　　③Mary isn't sad, is she?

　　④They won't come, will they?

　　此外，附加語中的代名詞(pronoun)和助動詞(auxiliary verb)必須和敘述句中的相符。

　　這類疑問句看似簡單，其實容易出差錯。其中一個錯誤便是附加語的時態(tense)不對，如：

　　⑤You could hardly expect him to help you, can you?

　　⑥The minister will talk about regional cooperation, wouldn't he ?

　　另外一種錯誤是助動詞的錯用，如：

　　⑦The clerks are working hard, don't they?

　　⑧Betty won't be a sportswoman, can she?

　　“isn't it”的濫用

　　最常見的錯誤來自“isn't it”的濫用，如：

　　⑨Jason likes this book very much , isn't it?

　　⑩She can sing well, isn't it?

　　11.Our team won, isn't it?

　　12.Young Singaporeans have become achievement - oriented , isn't it?

　　13.All our teachers are dedicated, isn't it?

　　14.They will go shopping on Sunday, isn't it?

　　這6個錯誤的附加語改正如下：

　　⑨Jason likes this book very much, doesn't he?

　　⑩She can sing well, can't she?

　　11.Our team won, didn't it?

　　12.Young Singaporeans have become achievement - oriented, haven't they?

　　13.All our teachers are dedicated, aren't they?

　　14.They will go shopping on Sunday, won't they?

　　"lsn't it ? "在下列3個句子中才是正確的用法：

　　15.It is fine today, isn't it?

　　16.That story book is interesting, isn't it?

　　17.It is worthwhile learning a second language well, isn't it?

　　現在再看看“John is smart , isn't it ?”錯在哪里。很明顯的，錯在附加語里的代名詞：應該是“he ”，不是“it”，全句如下：John is smart, isn't he?
