3.合作探究：

1)教學(xué)操練1a,1c,2c

學(xué)生看書本上1a的圖畫，根據(jù)圖畫，把1a,1c,2c中的語言點(diǎn)綜合起來，叫學(xué)生相互間回答問題。并用剛剛學(xué)到的目標(biāo)句型來操練。最后，抽查幾對(duì)學(xué)生，讓他們?cè)谌嗝媲?，按要求進(jìn)行對(duì)話。

5.梳理知識(shí)：本單元主要學(xué)習(xí)了一般過去時(shí)的被動(dòng)語態(tài)，包括其結(jié)構(gòu)與用法。利用幾項(xiàng)發(fā)明創(chuàng)造練習(xí)這一知識(shí)，最后用一篇小報(bào)告來完成寫作練習(xí)。

1)1885____________2)1876________________3)1927____________

4)1976________________5)JulieThompson_________6)ChelseaLanmon______

典型例題解析：

1.--Whataniceclassroom!--It____everyday.

A.iscleaningB.hascleanedC.mustcleanD.iscleaned

解析：推測這句話的意思應(yīng)該是“它每天都被打掃”，考查被動(dòng)語態(tài)的結(jié)構(gòu)be+動(dòng)詞的過去分詞。因此答案應(yīng)該選D。

2.IknowBeijingwell.I____therethreetimes.

A.willgoB.havebeenC.wentD.havegone

解析：推測這句話的意思“我很了解北京，我去過那三次”。表示去過應(yīng)該采用的時(shí)態(tài)是現(xiàn)在完成時(shí)，因此可排除A和C，區(qū)別havebeen和havegone,havebeen去過；havegone去了（還沒回來）。因此應(yīng)該選擇B。

中考連接：

1.--Lookatthesignontheright.--Oh,smoking____here.

A.doesn’tallowB.isn’tallowedC.didn’tallowD.wasn’tallowed
