注：在否定句中，atall可位于句末，也可跟在否定词后。如：Heisn’ttiredatall./He’snotatalltired.他一点也不累。另外，在口语中单独说notatall,可用来回答感谢或道歉。如：

A：Thankyouverymuch.多谢你了。B：Notatall.不客气。A：I’msorrytokeepyouwaiting.对不起，让你久等了。B：Oh,notatall.噢，没关系。2.atleast至少例如：Weshouldbrushourteethatleasttwiceaday.我们每天应该至少刷两次牙。Agoodcigarettewillsmokeatleasttenminutes.一支好烟至少可以抽10分钟。

反义短语：atmost至多3.although虽然；尽管例如：

Althoughmyuncleisold,helooksverystrongandhealthy.我的叔叔虽然老了，但他看上去还是很健壮。

注意：although引导的从句不能与but,however连用，但可与yet,still连用。4.Itis+adj.todosth.干某事是……例如：

Itisinterestingtoplaycomputergames.

玩电脑很有趣。-Itisveryimportant_____makeaplanbeforeanewterm.-Yes.Youmusttrytomakeitcarefully.A.ofB.forC.toC5.spendv.

花费；消耗例如：

Howdidyouspendyoursummervacation?

你是如何度过暑假的？Ispent5yuanonthisbook.

这本书花了我五十元。辨析take,spend,pay

例如：Itusuallytakesmehalfanhourtodomyhomework.做作业通常花费我半小时的时间。Studentsoftenspendoneandahalfhours(in)doinghomework.学生们经常花一个半小时的时间做作业。Ipaid10yuan

forthisbook.我买这本书付了十元钱。根据以上例句可知：

Ittakessb.sometimetodosth.

意为“花费某人……时间来做某事”。

spend的主语必须是人，而spend…onsth.意为“买某物花了……钱”。spend+时间+(in)doing意为“花费多少时间来做某事”。可以与ittakessb.sometimetodosth.来进行句型转换。pay

的主语必须是人，而“花钱买某物”为pay…for。2dAccordingtothearticleandthepiecharts,writesentenceswiththepercentagesusingalways,usuallyorsometimes.1.90%:__________________________________2.85%:__________________________________3.45%:__________________________________4.10%:__________________________________5.13%:__________________________________6.2%:___________________________________NinetypercentofthestudentsalwaysusetheInternet.Eighty-fivepercentoft
