1、定语从句教学设计课题定语从句课时3授课班级考点、知识点定语从句学习目标掌握定语从句关系词的选择重、难点掌握定语从句关系词的选择学习内容学生活动探究点一：关系代词that与which的区别：that和which一般可以换用只能够使用that的情况：1.当先行词为不定代词，如anything,nothing,everything,all,any,little,few,none,much,one等时用that.Donotbelieveeverythingthathetellsyou.2.当先行词被序数词或形容词最高级修饰时用that.Thefirstthi
2、ngthatIwanttodonowistohavearest.3.当先行词被all,any,every,each,few,no,some等词修饰时，关系代词只能用that.Thereiseverychancethatshewillsucceed.4.当先行词被thevery,theonly,thesame,thelast修饰时，关系代词用that.HeistheonlyoneofusthatknowsRussian.5.当先行词即有人又有物时，关系代词只能用that.Wetalkedaboutthepersonsandthingsthatwerem
3、emberedinschool.只能够使用which的情况：1.引导非限制性定语从句时用which.Jimpassedtheexamination,whichmadehisfatherquitehappy.2.介词之后只能用which.Idisliketheschooltowhichhebelongs.探究点二：介词+which/whom中介词的确定。1.与定语从句中的动词构成搭配ThemanaboutwhomItalkedatthemeetingisfromBeijingUniversity.=Theman(who/whom/that)Italke
4、daboutatthemeetingisfromBeijingUniversity.注意：Thisistheperson(who/whom/that)youarelookingfor.Thisisthepersonforwhomyouarelooking.(此句为错误用法)★for不能够提前，因为lookfor是动词词组，2.与定语从句所修饰的先行词构成搭配Hebuiltatelescope(望远镜),throughwhichhecouldstudythesky.探究点三：as与which在引导定语从句时的区别1.as与which都可以指代主句中的部
5、分或是整个句子的内容，有时候可以互换Hemarriedher,as/whichwasnatural.2.但是在下列情况中一般只能用as(1)as引导的定语从句可以放在句首，而which不能Asweknow,morethan70%oftheearthiscoveredwithwater.(2)as表“正如、正像”而which无此意。此时，as从句中常在know,expect,happen,pointout,plan,suggest等单词或是短语Hecamebackhomelate,asweexpected.(3)某些动词被thesame,such修饰时
6、，从句需要用as引导Thesehousesaresoldatsuchalowpriceaspeopleexpected.(4)但当先行词被thesame修饰时，也可以用that引导定语从句，但意思有所不同。thesame...as(指同样、同类、相似的)thesame...that(指同一个)Eg:ThisisthesamewatchasIlost.ThisisthesamewatchthatIlost.探究点四：关系词的选用1.先行词是person,people,those等后面定语从句多用who引导2.先行词是he,they,any,allone
7、等后面的定语从句多用who3.先行词兼指人与物时，须用that4.避免与先行词who重复时应该用that5.先行词兼在形容词最高级、序数词或only等词修饰时应该用that6.先行词是不定代词或被不定代词所修饰时，须用that7.强调句结构中多用that.（Itis...that...）8.介词之后，先行词指物要用which引导定语从句；指人用who引导定语从句。教学反思
