“Doyouthinkitwillrain？”“Yes，Ithinkso．”

“你认为会下雨吗？”“是的，我想是这样。”否定用法时，有两种表示方法：

目标解读“主语＋donot＋动词＋so”与“主语＋动词＋not”“Isitgoingtorain？”“Idon’texpectso．/Iexpectnot.”“天要下雨吗？”“我希望不下。”【特别提示】★think的否定式常用：Idon’tthinkso．★hope或beafraid应该用：Ihopenot／I’mafraidnot．“Areweontime？”“I’mafraidnot．”“我们准时到了吗？”“恐怕没有。”2）so和not还可用在say及“tell＋宾语”之后，如：Tomsaidso．汤姆这样说的。Miketoldmeso．迈克这样告诉我的。3）so（not）可用来代替if后面的从句。如：Hasthelettercome？Ifso，readit，please．来信了吗？如果来了，请读一读。目标解读4）分句替代词not，还可以和perhaps，possibly，probably，certainly，surely等情态副词搭配，构成带有情态意义的简略答语。如：

“Willhecome？”“Perhapsnot.（＝Perhapshewillnotcome.）”

“他要来吗？”“也许不会来。”5)在be，appear，become，get，keep，seem，prove，turn等系动词之后，替代前面已经提到过的用作表语的形容词或名词。例如：Iwasnotsatisfied,butItriedtoappearsotopleasehim.我并不满意，但是为了让他高兴，我尽量显得很满意。3.Taketurnstomaketheideasasinterestingorlivelyasyoulike.(P21)turn既可用作及物动词、不及物动词，又可用作连系动词。1）turn作及物动词时，意为“使……转动；翻转”，后接名词或代词。如：

turnout表示“结果……”turntosbforhelp向某人求助taketurnstodo/atdoing或dosthbyturns都表示“轮流做某事”的意思。It’sone’sturntodo...表示“轮到某人做某事。”目标解读4.Infact,Ilooklikeonetoo.(P22)one在这里应该看作是“a+名词”结构中省略了与前面相同的名词，但因为a不能单独使用，因此把a变成one。Acakemadeofwheatcostslessthanonemadeofrice.（one＝acake）句子中出现相同的名词时的一些替代用法：one：替代前面出现的单数可数名词，但前面一定有限定词；Mychilddoesn’tlikethisbook．Showheramoreinterestingone．ones：替代前面出现的复数可数名词，但前面一定有限定词；Thenewdesignsaremuchbetterthantheoldones.新的图案比旧的好多了。that：替代前面出现的单数可数名词，但后面一定有修饰语；I’lltaketheseatnexttothat(=theone)bythewindow.我坐在窗口的那个座位旁边。目标解读those：替代前面出现的复数可数名词，但后面一定有修饰语；

目标解读2）“a+名词”=one“a+修饰词+名词”=a...oneIdon’tlikethisbook.Pleasegivemearedbook.=aredoneIdon’tlikethisbook.Pleasegivemeabookwiththickcover.=one3）除了that/it外，其它几个词都不能替代不可数名词。5.Inaway,myprogrammerislikemycoach.(P23)inaway：用一种方法；从某种程度/某种角度来说Weshouldsolvetheprobleminawaywearemostfamiliarwith.Wehavewoninaway.intheway：挡路了；用那种方法Youareintheway.Pleasemoveaway.DoitinthewayIdidit.目标解读onthe/one’sway：在路上，就要来了Onmywaytoschool,Imetanoldfriendofmine.bytheway：顺便说一下，顺便问一下Bytheway,whowillgiveusaspeechtomorrow?【词汇网络】动词与way连用构成的短语：loseone’sway
