3aWhoinventedtea?Readingbyaccident

偶然，碰巧。1.Although

teawasn’tbroughttothewesternworlduntil1610,thisbeveragewasdiscoveredoverthreethousandyearsbeforethat.虽然茶直到1610年才传入西方世界,但这种饮料在三千多年前就被发现了。(1)although

conj.意为“虽然,尽管”,引导让步状语从句。我们不能根据汉语习惯,在后面使用连词but,不过它可以与yet,still连用。Thereisairaroundus,although

wecan’tseeit.尽管我们看不见,但我们周围全是空气。e.g.(2)

not…until意为“直到……才……”。注：until的主句中也可以用延续性动词，此时until不与not连用，表示“直到……为止”。用于not…until结构中的主句谓语多为短暂性动词。Hedidnot

gotobed

until

hisfathercamehome.直到他爸爸回家时他才睡觉。Iwillwaituntilhereturns.我将等到他回来。e.g.e.g.AccordingtoanancientChineselegend,theemperorShenNongdiscoveredteawhenhewasboilingdrinkingwateroveranopenfire.Someleavesfromanearbybushfellintothewaterandremainedthereforsometime.remain“继续留在某处”。
