3、 a tiger.一只大象比一只老虎更大。形容詞的比擬級是在形容詞的根底上變化而來的，它的變化規(guī)那么是: 一般的直接在詞尾加 er ,如 tall - taller , strong - stronger 以e結尾的，直接加r，如fine - finer , 以輔音字母加y結尾的，先改y為i再加er，女口funny - funnier, heavy-heavier 雙寫最后的字母再加er,如big - bigger, thin - thinner ,hot-hotter注意 比擬的兩者應該是互相對應的可比擬的東西。典型錯誤：My hair is longer than you.我的頭發(fā)比你更長

4、。比擬的兩者是我的頭發(fā)、你整個人，那么比擬的對象就沒有可比 性。應該改為： My hair is Ion ger tha nyours. 或 My hair is Ion gerthan your hair .比擬級專項練習一、從方框中選出適宜的單詞完成句子heavy tall long big(1) Howis the Y ellow River?How(4)How(2) Howis Mr Gree n?He' s 175cm.I wear size 18.s 2kg. re your feet?is the fish? It根據答句寫出問句 I ' m 160 cm. I

5、' m 12 years old. Amy s hair is 30 cm long.注意：How + 形容詞原形。二、根據句意寫出所缺的單詞(1) I ' m 12 years old.You' re 14.I ' mthan you. A rabbit ' s tail isthan amon key s tail.(3) An elepha nt istha n apig.(4) A lake istha n a sea.三、根據中文完成句子.(1)?我比我的弟弟大三歲.I ' mtha n my brother.？這棵樹要比那棵樹高.Th

6、istreetha n that one.？你 比他矮四 厘 米 .Youaretha n he.？誰比你重？tha n you？注意：當比擬時出現了差距比方，大了幾歲、高了幾厘米，重了 多少斤時，應將差距放在比擬級的前面，如：I am 2 years older tha n you.He is 10cm taller tha n me.三：動詞過去式詳解動詞的過去式的構成規(guī)那么有：A、規(guī)那么動詞 一般直接在動詞的后面加 ed女口 worked , learned , cleaned , visited 以e結尾的動詞直接加 d女口 lived , danced , used 以輔音字母加y結

7、尾的動詞要改y為i再加ed 此類動詞較少study studied carry carried worry worriedplay、stay 雙寫最后一個字母此類動詞較少如 stoppedE、不規(guī)那么動詞此類詞并無規(guī)那么，須熟記小學階段要記住以下動 詞的原形和過去式： sing - sang , eat - ate , see - saw , have - had , do - did , go - went , take - took , buy - bought , get got , read read ,fly flew , am/is was , are were , say sai

11、ot won ' t eat lunch at 12:00.I did not didn ' t wa tch TV yesterday evening.注意 小結：否認句主要是在肯定句的根底上加上了否認詞“not 。 1有動詞be的句子：可縮寫成“ isn ' t，aren ' t ， am not 。2沒有動詞be的句子：助動詞do，does，did力口 not， 可縮寫為“ don' t , doesn ' t , didn ' t 。這三個助動詞要根據 人稱和時態(tài)來選擇。三、一般疑問句：是指詢問事實的句子，此類句子必須用“ yes

12、，或“ no 來答復。m not.如：Are you a student? Yes,I am / No, IIs she a doctor? Yes, she is. / No, she isn' t.Does he work in a hospital? Yes, he does. / No, he doesn' t.Are there four fans in our classroom? Yes, there are. / No, there aren t.Are you going to buy a comic book toni ght?Yes, I am. / No

14、有動詞be的句子那么要在句首加上一個助動詞(do，does，did) 再把緊跟在后面的動詞變回原形，末尾標點符號變成問號即可。這三個助動詞也要根據人稱和時態(tài)來選擇般。一般疑問句有個重要的原那么就是問和答要一致，即怎么問就怎么答。同時注意人稱的變化。第一人稱要變?yōu)榈诙朔Q，如：I am listening to music.( 改為否認句)-Are you liste ning to music?(四) 、特殊疑問句：以特殊疑問詞(what , where , who , which , when , whose , why , how等)開頭引導的句子。此類句子應該問什么就答什么，不能 “ye
