Question

1 The dentist came to our school _______ our teeth
A for examine B to examine C as to examine D examine
请问第一题为什么选B呢?为什么前要加个to
2 Tome does his homework_____Lucy
A as carefully as B so carefully as C as careful as D so careful as
请问下这题要选什么?我觉得选B或D可是老师说选A 不是as.as和so.as之间加形容词吗?as.as表示和什么什么一样so.as表示不如.这个句子不是可以翻译成Tom做作业不如Lucy或Tom做的作业和Lucy一样吗?
3 The boy was too busy_____his father last term
A to hear from B to write to C hearing from D write to
为什么要选B呢?为什么write 前还要加一个to呢?

Answer 1

1. to do sth是目的状语,句意：要移到我们学校来检查我们的牙齿.到我们学校来的目的是检查牙齿,所以examine前加to.
2 选A.as.as和so.as中间加形容词或副词的原级,因为这里的carefully修饰的是动词does,所以要用副词,而so.as使用在否定和疑问句中的,否定句要有not,但这句话没有.as.as用在肯定句中.句意：汤姆做作业和露西一样认真.如果想说Tom做的作业和Lucy一样应该是：Tom does the same homeworke as Lucy. too.to意思是太.以至于不能做某事,句意：那个男孩上学期太忙了以至于不能给他爸爸写信.
