arrivein

London?火車什么時候到達倫敦？②get也是個不及物動詞，其后加介詞to,再接地點名詞；Whattimedoestheplane

getto

NewYork?這架飛機幾點到達紐約？③reach是及物動詞，其后可直接接名詞或代詞作賓語。Theyreachschoolat7o’clockinthemorning.他們早上7點到校。3.Thejourneyhastakenseveralmonths.旅途花了幾個月的時間。句型:

Ittakessb.sometimetodosth.意為“某人花（多少）時間做某事”，其中it是形式主語，動詞不定式todosth.是真正的主語；常與句型sb.spend…(in)doingsth.互換。

theother(s)與other(s)的區(qū)別：(1)

theother與other后可加名詞;theothers與others后不加名詞；(2)

theother(s)表示一定范圍內(nèi)除去一部分以外后其余的全體；other(s)表示除去一部分以后的（一些），但不是剩下的全體。LanguagePoints

otherapples/others,please!請另給我一些（蘋果）吧！2.Noneofthemhasanenvironmentlikethatoftheearth.它們中沒有一個有像地球這樣的環(huán)境。noone與none的區(qū)別：(1)

noone同義詞為nobody,只用于指人，其后不跟of短語，作主語時謂語用單數(shù)，noone只能回答以who開頭的問句；(2)

none用于表示對三者或三者以上全部否定，既可指人，也可指物。作主語時，謂語可以是單數(shù)，也可以是復數(shù);none的反義詞是all,none可與of連用;可以用來回答Howmany或Howmuch開頭的問句。Noneof

lonely只作為形容詞，意為“孤獨的，寂寞的”，具有感情色彩。Helivedaloneafterhiswifeleft，sohewasverylonely.他妻子離開后，他一個人生活，所以他很孤獨。—Whathavethescientistsjustheard?(amessagefromaspaceship)—They’vejustheardamessagefromaspaceship.5Lookatthecartoonpictureandanswerthequestions.1.Wherehasthespaceshiplanded?

“某人已經(jīng)做了某事”等意思時,英語要用“現(xiàn)在完成時”來表達。

否定句Ihavenotworked.He/Shehasnotworked.Theyhavenotworked.

肯定句Ihaveworked.He/Shehasworked.Theyhaveworked.haven’thasn’thaven’t現(xiàn)在完成時的結構：has/have+done(動詞過去分詞)She/He/It/或sb.的單數(shù)形式hasdonesth.I/We/You/They或sb.的復數(shù)形式havedonesth.現(xiàn)在完成時的一般疑問句形式是：Hasdonesth.?she/he/it/或sb.的單數(shù)形式Havedonesth.?I/we/you/they/或sb.的復數(shù)形式現(xiàn)在完成時的肯定形式是：我父母曾經(jīng)坐船去大連旅游。她已經(jīng)完成作業(yè)。我父母未曾坐船去過大連旅游。MyparentshavetravelledtoDalianbyship.Shehasfinishedherhomework.Myparentshaven’ttravelledtoDalianbyship.她還沒有完成作業(yè)。你父母曾經(jīng)坐船去大連旅游過嗎？她已經(jīng)完成作業(yè)了嗎？HaveyourparentstravelledtoDalianbyship?Hasshefinishedherhomework?Shehasn’tfinishedherhomework.要表達“剛剛做完某事”“已經(jīng)做完某事”時，我們同樣可以用現(xiàn)在完成時。例如:Ihavejustheardthenews.Astronautshavealreadybeentothemoon.可以看出，just用來表示“剛剛”，already用來表示“已經(jīng)”，一般置于have/has之后，兩者都用于肯定句，在否定句中則要用yet,表示“還（未）”。例如：Thescientistshaven’theardfromit

yet.

havebeento

與havegoneto

的區(qū)別

1.（1）have/hasbeento意為“曾經(jīng)去過某地”，表示現(xiàn)在已經(jīng)不在那里了。可與just,ever,never等連用。例如：I’ve

just

beento

thepostoffice.我剛才去郵局了。Have

youever

beento

Hangzhou?你曾經(jīng)去過杭州嗎？Mary

has

never

beento

theGreatWall.瑪麗從未去過長城。（2）have/hasbeento后面可接次數(shù)，表示去過某地幾次。I’ve

beento

Beijingthreetimes.我去過北京三次。They

havebeento

thatvillageseveraltimes.他們已經(jīng)去過那個村莊好幾次了。2.have/hasgoneto意為“到某地去了”，表示到了某地或正在去某地的途中?？傊?，說話時該人不在現(xiàn)場，一般不用第一、第二人稱代詞作句子的主語。例如：

—WhereisTom?——湯姆在哪里？

—Hehasgonetothebookshop.——他到書店去了。與現(xiàn)在完成時連用的幾個副詞：肯定句:疑問句和否定句:yet常置于句末already,never,ever,just一般置于助動詞have/has之后，過去分詞之前。already,just,ever,yet,never
