雖然茶直到1610年才傳入西方世界,但這種飲料在三千多年前就被發(fā)現(xiàn)了。(1)although

作連詞,意為“雖然,盡管”,引導(dǎo)讓步狀語從句,我們不能根據(jù)漢語習(xí)慣,在后面使用連詞but,不過它可以與yet,still連用;若主從句的主語相同,且從句謂語含有動詞be,可將從句主語和動詞be省略。

Although(itwas)snowing,itwasnotverycold.

雖然在下雪,但是天氣不是很冷。

Thereisairaroundus,although

wecan’tseeit.

盡管我們看不見,但我們周圍全是空氣。not…until

意為“直到……才”until引導(dǎo)一個時間狀語從句。

根據(jù)中國古代的一個傳說,神農(nóng)帝在戶外的火上燒飲用水時發(fā)現(xiàn)了茶葉。

是個短語介詞,意為“根據(jù)……;依照……”后接代詞,名詞或由疑問詞以及whether引出的名詞性從句。

Accordingtotheradio,itwillraintomorrow.根據(jù)收音機(jī)說,明天有雨。

Accordingtowhatyousaidjustnow,hewasrightthen.

根據(jù)你剛才說的,那么他就對了。leaf的復(fù)數(shù)形式為leavesremain

表示“繼續(xù)留在某處”3.Someleavesfromanearbybushfellintothewaterandremained

thereforsometime.

一些葉子從附近的灌木叢落到水里。并在水里浸泡了一段時間。Howlongwillyouremainhere?

你要在此地停留多久?fallinto“落入,陷入”

Hewasdrunkandfellintothewater.

他酒醉跌落水中。4.Theemperornoticedthattheleavesinthewaterproducedapleasantsmell.國王注意到,水里的葉子發(fā)出一種宜人的香味.(1)Notice

作動詞,意為“注意到”,后可以接:名詞或代詞.如:Ididn’tnoticeyourparents.我沒注意到你的父母親.(2)從句.如:Inoticedthatyouweren’tamongthecontestants.我注意到你沒有參加比賽.(3)復(fù)合結(jié)構(gòu)Didyounoticehimrepairhiscaryesterdayevening?昨晚你注意到他修車了嗎?Inoticedhersinginginthenextroom.我注意到她正在隔壁唱歌.
