isonitscover.这本书一定是杰克的,因为封面上有他的名字。(2)largeadj.大的,巨大的。常指面积或范围大,其反义词为small(小的)。
(3)enoughadv.足够地。修饰形容词或副词时要放在所修饰词的后面。例:Thisgirliscarefulenough.这个女孩足够的细心。Languagepoints2.Now,puttheseedlinginside,covertherootsandfilltheholewithdirt.(1)cover
v.覆盖。常用短语:cover…with…用……盖住……其被动语态结构为:becoveredwith…被……覆盖。例:Pleasecoverthepotwithapieceofpaper.请用一张纸盖住这口锅。(2)fill
v.装满;充满。常用短语:fill…with…用……装满……;befilledwith…被装满/充满……例:Hefilledthebottlewithwine.他用酒装满了那只瓶子。Thenewroadsandstreetswillbefilledwithmanycarsandbusessoon.
新的道路又将被很多公共汽车和小汽车塞满。3.Bytheway,thereisanothergroupofpeopledownthehill.
bytheway是固定搭配,意为“顺便说/问一下”。
常放在句首,用于在主要话题或交流中插入题外
的话或问题。例:Bytheway,howoldareyou?
顺便问一下,你多大了?4.Ms.Liutoldusthewindblowsthedirtandthesandherefromthenorth.此句中,us后面是一个省略了连词that引导的宾语从句。主句为一般过去时,宾语从句用相应的过去时态。但在英语中,如果宾语从句陈述的是客观事实、自然现象、科学真理等时,从句的时态不受主句时态的限制,用一般现在时。例:HeknewthattheYangtzeRiveristhelongestriverinChina.他知道长江是中国最长的河流。5.Nothingcanstopthewindbecausetherearenotmanytreesleft.此句是一个主从复合句。句中because引导原因状语从句。because表示直接的原因,常用来回答why引导的特殊疑问句。
【链接】其他用来引导原因状语从句的连词:①for引导的从句是对主句发生的动作一些补充说明,且不可位于主句之前。②since意为“既然”,引导的从句表示附带的原因,或者表示已知的、显然的理由,通常放在句首。③as所表示的原因语气最弱,只是对主句的附带说明,重点在主句。as从句通常放在主句之前。例:Iwenttoseehim,forIhadsomethingtotellhim.我去见他,因为我有事要告诉他。Sincewehavenomoney,wecan'tbuythatcar.既然我们没钱,就不能买那辆车了。Asitisraining,you'dbettertakeataxi.下雨了,你最好乘出租车。6.It'salsoagreatwaytolearnaboutnature.
awaytodosth.意为“做某事的一种方式/方法”。其中,不定式作way的后置定语。相当于awayofdoingsth.。例:It'sagoodwaytolearnEnglish.=It'sagoodwayoflearningEnglish.这是一个学习英语的好方法。
Itis+adj.+for/ofsb.todosth.对于某人来说,做某事是……的。例:It'skindofyoutohelpmeyesterday.昨天你帮助了我,你真是太好了。7.
Oh,andpleaseremembertoputalittlewaterinthebottomofthehole.(1)remembertodosth.记得要做某事(此事还未做)。例:Remembertoclosethewindowwhenyouleavetheoffice.你离开办公室时,记得关窗户。(2)at/inthebottomof…在……的底部。例:IwanttotellyoufromthebottomofmyheartthatIamtrulysorry.我从心底想向你表示我真的很抱歉。
