These dogs can help him.
She sells seashells
1.改复数句就是把句子从头到尾都改成复数形式,从主语到谓语,宾语全部都改。this->these,dog->dogs,情态动词的复数仍然不变,情态动词后面的动词形式也不会发生变化(因为跟在情态动词的后面),him->them 所以这个对应下来就是:These dogs can help them. 2动词的形式取决于时态以及主语的形态。前面的主语是第三人称单数,所以要是用现在进行时就是is selling,一般现在时的话就是sells,所以根据选项的话呢 只有C项的答案是符合语法的
1、These dogs can help him.
那些狗可以帮助他。
2、She sells seashells.
她卖贝壳。
顺便帮你讲讲英语复数的语法吧。
1、名词由单数变复数的基本方法如下:
①在单数名词词尾加s。如:map → maps,boy→ boys,horse→ horses, table→ tables.
②s,o,x ,sh,ch结尾的词加es.如:class→classes, box→boxes, hero→heroes, dish→dishes, bench→benches.
[注]:少数以o结尾的词,变复数时只加s。如:photo→photos, piano→pianos.
③以辅音字母加y结尾的名词,变y为i,再加es。如:family→families, city→cities, party→parties.
④以f或fe结尾的名词,变f或fe为v,再加es。如:shelf→shelves, wolf→wolves, life→lives, knife→knives.
2、不规则变化:man→men, woman→women, sheep→sheep,tooth→teeth, fish→fish, child→children, ox→oxen, goose→geese
不可数名词一般没有复数形式,说明其数量时,要用有关计量名词。如:a bag of rice→two bags of rice, a piece of paper→three pieces of paper, a bottle of milk→five bottles of milk.
