1、人教九年级英语上册Unit8ItmustbelongtoCarla.SectionA（1a-2d）LeadinginWhosebearisthis?ItmustbeLinda'sbecauseit'sinherbed.WhoseT-shirtisthis?ItmustbeTom'sbecausehewasinityesterday.语法重点一1.ItmustbelongtoCarla.它一定是属于卡拉的。belongto意为“属于，为……所拥有”。belongto没有被动语态，也不能用于进行时态。belongt

2、o后可接名词或代词宾语，不能接物主代词，也不能接名词所有格。如：ThebluesweaterbelongstoLiMing.Hismotherboughtitforhimyesterday.TheboybelongstothesinginggroupofGradeOne.Thisbookbelongstome.ThatnewbikeinthecornerbelongstoHelen.2.ItmustbeCarla’s.Shelovesvolleyball.它一定是卡拉的，她喜欢排球。语法重点二(1)must为情

3、态动词，无人称和数的变化，后接动词原形。注意在回答must引起的一般疑问句时，否定式常用needn’t或don’thaveto，意为“没必要”，而mustn’t表示“不准；禁止”。如:---MustIfinishtheworkontime.---Yes,youmust./No,youneedn’t/don’thaveto.（2）此处must表示推断，通常与be连用，意为“一定是，肯定是”。must这种表示推测的用法只用于肯定句中如：Theremustbesomethingwrongwiththecomputer

4、.①must表示肯定推测时，其否定形式是can’t，意为“不可能”，表示有把握的否定推测。如：Wemustbewrong.（改为否定句）→Wecan’tbewrong.②might或could表示肯定推测时，意为也许是，可能是，其否定形式是can’t。如：Theredpencan’tbeLucy’s.Itmight/couldbeLily’s.PersonThingReasonJane’slittlebrothervolleyballJ.K.Rowlingisherfavoritewriter.Marytoyt
