2)教學(xué)1b, 2a, 2b
首先，幫助學(xué)生明確本題的要求。接著，聽力練習(xí)，學(xué)生根據(jù)錄音內(nèi)容完成1b, 2a and 2b.
最后，重放一遍錄音內(nèi)容，學(xué)生跟讀。

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)。
6.達(dá)標(biāo)測試：
（一）根據(jù)時(shí)間和人物寫出發(fā)明物。

3)計(jì)算機(jī)是用來做什么？
4)你認(rèn)為什么是最有用的發(fā)明？
5)它能夠給人們更多時(shí)間工作和玩。
典型例題解析：
1.--What a nice classroom! --It ____ every day.
A. is cleaning B. has cleaned C. must clean D. is cleaned
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.I know Beijing well. I ____ there three times.
A .will go B. have been C. went D. have gone
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have been和have gone,have been 去過；have gone 去了（還沒回來）。因此應(yīng)該選擇B。
中考連接：
1.--Look at the sign on the right. --Oh, smoking ____ here.
A .doesn’t allow B. isn’t allowed C. didn’t allow D. wasn’t allowed
