48、特征、性格、能力等。2現(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：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，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)”，既可以表示經(jīng)歷過也可以是從來都沒有經(jīng)歷過。3被動(dòng)語態(tài) 初中階段我們學(xué)習(xí)了八種被動(dòng)結(jié)構(gòu)，歸納如下：(1)一般現(xiàn)在時(shí)的被動(dòng)式：(2)現(xiàn)在完成時(shí)的被動(dòng)

50、謂語，也沒有人稱和數(shù)的變化。后面一般跟動(dòng)詞原 形。5 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+ didn't use to 。在英式英語中，它的疑問式應(yīng)當(dāng)是：Used +主語+ to do sth.?否定式應(yīng)當(dāng)是 used not to或usedn't to。如：He used to stay up late.他過去常熬到很晚。 【實(shí)戰(zhàn)演練】I .
