1、Unit8 语法 Section A (1a-2d) 语法重点一1. It must belong to Carla. 它一定是属于卡拉的。belong to意为“属于，为所拥有”。 belong to没有被动语态，也不能用于进行时态。belong to 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。2. It must be Carlas. She loves volleyball. 它一定是卡拉的，她喜欢排球。语法重点二 (1)must为情态动词，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neednt或dont have to，意为“没必

2、要”，而mustnt表示“不准；禁止”。如:-Must I finish the work on time. -Yes, you must. /No, you neednt/dont have to. （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：There must be something wrong with the computer. must表示肯定推测时，其否定形式是cant，意为“不可能”，表示有把握的否定推测。 如：We must be wrong. （改为否定句） We cant be wrong. migh

3、t或could表示肯定推测时，意为也许是，可能是，其否定形式是cant。 如：The red pen cant be Lucys. It might/could be Lilys. 3. I cant remember!

10、式。3） 情态动词没有人称、数的变化，即情态动词第三人称单数不加-s。 4） 情态动词没有非谓语形式，即没有不定式、分词等形式。 掌握情态动词的定义：表示可能、怀疑、允诺、愿望、义务、必要、猜测等的动词是情态动词。 can 可表示能力、允许、可能性、怀疑猜测，意为“可以，会，能”；cant意为“不会，不能，不可以”，还有“不可能”之意。could为can的过去式，用法与can类似，常用于过去时中；could还可用于现在时中表示委婉客气，相当于can；could也可表示惊讶怀疑，不相信。1can如：He couldnt be a thief.2maymay表示允许、也许，意为“可以，也许，可能”
