這里的have/has是助動(dòng)詞,沒有具體意義。當(dāng)主語是第三人稱單數(shù)時(shí),助動(dòng)詞用has,其余人稱用have。1.句式結(jié)構(gòu):◆否定式:主語+助動(dòng)詞have/has+not+過去分詞＋其它。如:Shehasn’ttravelledonatrainyet.

她還未坐過火車旅行。[注意]havenot,hasnot的縮略式分別為haven’t,hasn’t。◆一般疑問式:Have/Has+主語+過去分詞+其它?如:—Haveyouevermadedumplings?

你曾包過餃子嗎？—Yes,Ihave.

是的,我包過。[注意]

把陳述句中的have或has放到句首,句末用問號(hào),同時(shí)把句中的some,already改為any,yet就構(gòu)成了一般疑問句。

肯定回答:Yes,主語+have/has.

否定回答:No,主語+haven’t/hasn’t.否定回答也可以用：

No,notyet./No,never.等。IhavebeentoNewYork.Idon’twanttogothereagainthissummer.我去過紐約，這個(gè)暑假我不想再去了。—Haveyoureceivedhisletter?你收到他的信了嗎？—Yes,Ihave./No,Ihaven’t.是的,我收到了。/不,我沒有。Haveyouevertriedwesternfood?你吃過西餐嗎？過去分詞的構(gòu)成:規(guī)則動(dòng)詞

①動(dòng)詞后加-ed,如：work—worked,cook—cooked。②以e結(jié)尾的動(dòng)詞加-d,如：live—lived,like—liked。③以“輔音字母+y”結(jié)尾的動(dòng)詞將y改為i再加-ed,如：try—tried,carry—carried。④末尾只有一個(gè)輔音字母的重讀閉音節(jié)詞,先雙寫這個(gè)輔音字母,再加-ed,如：stop—stopped,drop—dropped。(2)不規(guī)則動(dòng)詞

不規(guī)則動(dòng)詞的過去分詞形式需要特殊記憶,如：see—seen,be—been,take—takenUnit2TheyhaveseenthePyramids.thePyramidsinEgyptPyramidsfunctionedastombsforpharaohs.1.WhichinterestingplacesinChinahaveyouvisited?2.HaveyoueverseentheGreatWall?3.Haveyouevervisitedanothercountry?1.HowlonghavetheRobinsonsbeeninEgypt?
