Post-itNotes拓展閱讀1.byaccident意為“偶然；意外地”。介詞短語(yǔ)，在句中作狀語(yǔ)，相當(dāng)于bychance,其反義詞組為onpurpose（故意地）。例句：?Hegotthesecretbyaccidentyesterday.

昨天他偶然得知了這個(gè)秘密。

?Manyimportantdiscoveriesweremadebyaccident.很多重要的發(fā)現(xiàn)都是在偶然情況下發(fā)生的。LanguagePoints2.ItissaidthataChineserulercalledShenNongwasthefirsttodiscoverteaasadrink.據(jù)說(shuō)有一位叫作神農(nóng)的中國(guó)統(tǒng)治者最早發(fā)現(xiàn)了茶可以飲用。Itissaidthat意為“據(jù)說(shuō)……”。其中it作形式主語(yǔ)，真正的主語(yǔ)是that引導(dǎo)的從句。

例句：?ItissaidthattheyhavefoundwateronMars.

據(jù)說(shuō)他們?cè)诨鹦巧习l(fā)現(xiàn)了水。thefirsttodosth.

意為“第一個(gè)做某事的人”，是“the+序數(shù)詞+todosth.”結(jié)構(gòu)，動(dòng)詞不定式作定語(yǔ)。例句：?Maryisalwaysthefirsttoarriveattheclassroom.

瑪麗總是第一個(gè)到教室。

?Youarethesecondtoaskmethatquestion.

你是第二個(gè)向我提出那個(gè)問(wèn)題的人。3.fallinto：掉進(jìn)；落入（圈套）；陷入“動(dòng)詞+介詞”構(gòu)成的短語(yǔ)，fall多用作不及物動(dòng)詞。例句：?Hefellintotheriver.他掉進(jìn)河里。?Thechildfellintothelakeandhadtobepulledout．

小孩落入湖中，必須把他拉上來(lái)?！就卣埂颗cfall相關(guān)的短語(yǔ)：fallbehind落后

falldown摔倒

falloff掉下fallasleep入睡4.remain作不及物動(dòng)詞，意為“剩下；停留；逗留”。例句：?Afewpearsremainonthetrees.

樹(shù)上還留有幾個(gè)梨。?Sheremainedinherofficeallafternoon.

她整個(gè)下午都待在辦公室里?！就卣埂縭emain用作連系動(dòng)詞時(shí)，意為“保持；仍是”，后接形容詞、名詞、動(dòng)詞-ing形式或介詞短語(yǔ)作表語(yǔ)。例句：?Theroomremainscoolallsummer.

這個(gè)房間整個(gè)夏天都保持涼爽。?Sheremainedsittingwhentheycamein.

他們進(jìn)來(lái)時(shí)，她仍然坐著。5.

takeplace發(fā)生；出現(xiàn)常指有計(jì)劃、有安排地“發(fā)生”，是不及物動(dòng)詞短語(yǔ)，不能接賓語(yǔ)，一般也不用作被動(dòng)結(jié)構(gòu)。例句：

會(huì)議將在大廳舉行。?Themeetingwilltakeplaceinthehall.選舉每四年舉行一次。?Electionstakeplaceeveryfouryears.take
