例句：►ItissaidthattheyhavefoundwateronMars.

据说他们在火星上发现了水。thefirsttodosth.

意为“第一个做某事的人”，是“the+序数词+todosth.”结构，动词不定式作定语。例句：►Maryisalwaysthefirsttoarriveattheclassroom.

玛丽总是第一个到教室。

►Youarethesecondtoaskmethatquestion.

你是第二个向我提出那个问题的人。3.fallinto：掉进；落入（圈套）；陷入“动词+介词”构成的短语，fall多用作不及物动词。例句：►Hefellintotheriver.他掉进河里。►Thechildfellintothelakeandhadtobepulledout．

reportedthat…据报道……；It’sknownthat…众所周知……；Itissupposed/thoughtthat…人们认为……。6.not…until…

直到……才……主句的动词一般是非延续性动词，它所表示的动作直到until所表示的时间才发生。until可作介词，其后接表示时间的名词，也可作连词，引导时间状语从句。例句：►Ireaduntiltwoo’clock.我看书一直到两点。►Youcan’tleaveuntilyourworkisfinished.

直到你的工作完成你才能离开。7.lessthan意为“较少，比……少；不及，不如”。例句：

分开是“一段”，相连为“某时”;

分开s是“倍、次”，相连s是“有时”。我们将在八月的某个时候度假。我每天花一些时间练习说英语。We’lltakeourholidaysometimeinAugust.IspendsometimepracticingspeakingEnglisheveryday.11.smell做名词还有“嗅觉；嗅”的意思。►Thedogscanfinddrugsby
