it、one、that的用法与区别.ppt

替代词it，that，one(s)，those用法区别

【学习目标】为了防止重复,it,that,one(s),those都可用来代替上文出现的名词，但它们的用法不同。

一般说来,it指代同名同物;one与that那么指代同名异物。?Ihavelostmyumbrella;Imlookingforit.?Ihavelostmyumbrella;IthinkImustbuyone.?TheumbrellayouboughtischeaperthanthatIbought.one指anumbrella(泛指〕that指theumbrella(特指〕

one泛指所代替名词是可数名词,其前可带冠词与修饰语。如代替复数名词，那么用ones。Thepopulationproblemmaybethegreatestoneintheworldtoday.(one代替可数名词problem)-Whichjacketsareyours?-Thewhiteones.(ones代替可数名词jackets)

that代替前面提到的特指的事物〔可数名词/也不可数名词)，其前通常不能有修饰语。?Thedoctorinourschoolisyoungerthanthatintheirschool.

?Theweatherofthisweekisworsethanthatoflastweek.?Thequalityofironproducedinyourfactoryisbetterthanthatintheirfactory.

those代替前面提到的同名异物中特指的事物，只能指代复数名词，相当于theones。

??Thecomputersinyourofficearemoreexpensivethanthoseinourschool.(those代替复数名词computers)

?InChinastudentslearnEnglishatschoolasaforeignlanguage，exceptforthoseinHongKong，wheremanypeoplespeakEnglishasafirstorasecondlanguage.(those代替复数名词students)

it可以替代句中的不定式或从句等,充当形式主语或形式宾语。one与that均无此用法。

??Hehassavedmylife;Illneverforgetit.?Letssaywemeethereatthreeoclock.Thatoughttogiveyoutimetobuyeverything.?Itisknowntoeverybodythatthemoontravelsaroundtheearthonceeverymonth.?Ifoundithardtogetonwithher.

it与that均可以替代上文全句的内容或局部内容,而one／ones那么不可以。
