1.Potatochipswereinventedbymistakes.mistake作名詞“錯誤，誤會”。也可以作動詞“弄錯，犯錯”。常見形式有：makeamistake

出錯e.g.Youhavemadeamistakehere.mistake…for…

錯把……當(dāng)作……Theymistookhimforhisbrother.bymistake

錯誤地

e.g.Theysentthelettertomebymistake.3.Didyouknowthattea…wasinventedbyaccident?byaccident“偶然地，碰巧”。同義詞組是bychance，同義詞是accidentally,反義詞組是onpurpose.4.Althoughteawasn’tbroughttothewesternworlduntil1610,…(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;e.g.Althoughheisverybusy,healwaystalkswithus.(2)not…until

意為“直到……才”until引導(dǎo)一個時間狀語從句。

Ididnot

gotobed

untilIfinishedmyhomework.5.AccordingtoanancientChineselegend，theemperorShenNongdiscoveredtea…(1)accordingto

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。e.g.Accordingtotheradio,itwillraintomorrow.(2)discover意為“發(fā)現(xiàn)”，指發(fā)現(xiàn)的對象是本來存在的。

find意為“找到”，強(qiáng)調(diào)結(jié)果。

invent意為“發(fā)明”，發(fā)明的對象是以前沒有的東西。3b.Writeanarticleusingthenotes
