10、示主語的特征、性格、能力等本單元復(fù)習(xí)現(xiàn)在進(jìn)行時(shí)、used to句型、被動(dòng)語態(tài)、現(xiàn)在完成時(shí)和情態(tài)動(dòng)詞?，F(xiàn)在完成時(shí)（1）含義：表示過去發(fā)生的動(dòng)作對(duì)現(xiàn)在還有影響。（2）基本結(jié)構(gòu)：主語 + have / has + 過去分詞（3）基本用法：表示過去發(fā)生的動(dòng)作，但強(qiáng)調(diào)對(duì)現(xiàn)在產(chǎn)生影響。特征：不能與表示具體的時(shí)間狀語連用。表示過去發(fā)生的動(dòng)作或存在的狀態(tài)一直延續(xù)到現(xiàn)在，還可能繼續(xù)下去。常常與since, for, in the past + 時(shí)間名詞，in the last +時(shí)間名詞等時(shí)間狀語連用，而且謂語動(dòng)詞要求是延續(xù)性動(dòng)詞。表示一種“經(jīng)歷或體驗(yàn)”，即可以表示經(jīng)歷過也可以是從來都沒有經(jīng)歷過。被動(dòng)語態(tài)初中階

11、段我們學(xué)習(xí)了七種被動(dòng)結(jié)構(gòu)，歸納如下：（1）一般現(xiàn)在時(shí)是被動(dòng)語態(tài)：am / is / are + 過去分詞（2）現(xiàn)在完成時(shí)的被動(dòng)式： have / has + been + 過去分詞（3）現(xiàn)在進(jìn)行時(shí)的被動(dòng)式：am/ is/ are + being + 過去分詞（4）一般過去時(shí)的被動(dòng)式：was / were + 過去分詞（5）過去進(jìn)行時(shí)的被動(dòng)式：was / were + being + 過去分詞（6）過去完成時(shí)的被動(dòng)式：had + been + 過去分詞（7）一般將來時(shí)的被動(dòng)式：will / be going to be+ 過去分詞（8）含有情態(tài)動(dòng)詞的被動(dòng)式：情態(tài)動(dòng)詞+be +動(dòng)詞的過去分詞。情態(tài)

12、動(dòng)詞情態(tài)動(dòng)詞表示說話人對(duì)某一動(dòng)作或狀態(tài)的態(tài)度，如認(rèn)為“可能”、“應(yīng)當(dāng)”、“必要”等。情態(tài)動(dòng)詞本身有一定的意義，但不能單獨(dú)作謂語，也沒有人稱和數(shù)的變化。后面一般跟動(dòng)詞原形。used to 結(jié)構(gòu)used to意為“過去常常做某事”，指的是過去的習(xí)慣性動(dòng)作，目的在于與現(xiàn)在形成對(duì)照。used to是個(gè)情態(tài)動(dòng)詞，其中的to是不定式符號(hào)，后面跟動(dòng)詞原形。在美式英語中。它的疑問式是：Did 主語use to do sth？否定式是：主語didnt use。在英式英語中，它的疑問式應(yīng)當(dāng)是：Used 主語to sth？否定式應(yīng)當(dāng)是used not to或use（d）nt to。He used to stay u
