—Yes.Twoweeksago.A.still B.alreadyC.yet D.just2.Ihave_____sungthisEnglishsong,butshehasn't.

A.already B.yetC.never D.justBA2.Whatareyouupto?beuptosth.是固定短語(yǔ),意為“正在做某事,忙于某事”。Whatareyouupto?等于Whatareyoudoing?例如:Whatisheuptowithallthosebooksonthefloor?這么多書放在地上,他在干什么呢?當(dāng)我們說beuptosb.,則表示“由某人決定”。例如:—Doyouwanttostayorgo?你是留下來還是走呢?—It'suptoyou.由你決定。做一做:單項(xiàng)選擇。1.—Whatareyouup____?

A.down B.offC.up D.awayBC3.Astronautshavealreadybeentothemoon.辨析:have(has)beenin,have(has)beento和have(has)goneto(1)have(has)beenin意為“已經(jīng)在某地待了多長(zhǎng)時(shí)間”,常與表示一段時(shí)間的狀語(yǔ)連用。例如:Mr.BrownhasbeeninShanghaiforthreedays.布朗先生來上海已經(jīng)有三天了。(2)have(has)beento意為“已經(jīng)去過某地”,表示現(xiàn)在已經(jīng)不在那里了?？膳cjust,ever,never等連用。例如:I'vejustbeentothepostoffice.我剛才去郵局了。(3)have(has)goneto意為“已經(jīng)去了某地”,表示到了某地或正在去某地的途中。總之,說話時(shí)該人不在現(xiàn)場(chǎng),一般不用第一、第二人稱代詞作句子的主語(yǔ)。例如:—WhereisTom?湯姆在哪里?—Hehasgonetothebookshop.他到書店去了。做一做:單項(xiàng)選擇。1.—Haveyouever____toHangzhou?
