初三英語知識點總結有哪些
初三的時候，要想學好英語，就必須學好英語知識點。下面是小編爲你推薦初三英語知識點總結，希望能幫到你。
英語名詞分可數的和不可數兩種。可數名詞指一般動物和事物，如“Man/ friend/ driver/ student/ dog/ cat/ boat/ egg/ gun/ hand/ head/ lamp/ road/ table/ car ”等等。
可數名詞有兩個數，即單數和複數。單數名詞可以和不定冠詞“ a/ an”或其他名詞限定詞(determiners)連用;複數名詞可以和數目詞，如“many/ a few/ some/ a lot of”等連用。
不可數名詞指物質名詞(material nouns)和抽象名詞( abstract nouns)，如：“air/ butter/ grass/ money/ sand/ water/ carefulness/ joy/ peace”等等。不可數名詞可以和數量詞，如“much/ a little/ little/ a great amount of”等連用。不可數名詞只有單數，沒有複數“-s”的形式。
有些人對名詞數的概念不很清楚，對數目詞(expressions of number)和數量詞(expressions of quantity)也有些混亂，結果把數目詞用在不可數名詞之前或隨意在不可數名詞後面加上覆數詞尾 “-s”，這些都是語法上的錯誤。例如：
① Our workshop has ordered some new equipments from Germany.
雖然有些人把 equipment(配備)當成可數名詞，但是它是不可數的，不可有“-s”。
② My teacher gave me some sound advices. 應該是“advice”。
③ Do you have any special informations for me? “Information”纔對。
④ Most furnitures in my house are made of wood. 應該是“furniture……is……”
⑤ Today, I have many new works to do. 必須是“a lot of new work”纔是。
⑥ Don't walk on the grasses. 應該用“grass”。
⑦ Our foreign students have made great progresses in their studies. “Progress”(進步)不可數;不可有“-es”。
⑧ All his money are kept in the bank. “Money”(金錢)屬不可數名詞;動詞要單數的“is”。
上述這類有關不可數名詞的錯誤，極爲普遍;只要看看學生的作文，便知道了。
既然如此，要怎樣避免這種錯誤呢?
首先，必須牢記不可數名詞絕對沒有複數形式。其次，隨時準備些數量詞，如“much/ little/ some/ a little/ a lot of/ plenty of”等，以便在必要時和不可數名詞連用。最後，謹記：謂語動詞必須和主語的數目一致。既然不可數名詞沒有複數形式，那麼謂語動詞若是簡單現在時態(simple present tense)，現在進行時態( present continuous tense)或現在完成時態(present perfect tense)的話，就必須以單數形式出現。例如：
⑨ Bread is sold in coffee shops and supermarkets.
⑩ His luggage is somewhere at the railway station.
1. Some money is being used to help the poor.
2. The information required includes personal particulars and the present salary.
3. A lot of time has been spent on this project.
4. Hypocrisy gives rise to mistrust.
5. Familiarity breeds contempt.
