Question

【題目】We __________ buy the train tickets. We can book one by phone now.

A. needn’t to B. don’t need to

C. need to D. need

Answer 1

【答案】B

【解析】句意：我們不需要買火車票�，F(xiàn)在我們可以打電話預(yù)定了。need作為情態(tài)動(dòng)詞常常用于對(duì)must一般疑問句的否定回答，needn’t不必。作為實(shí)意動(dòng)詞，意為“需要”。need to do sth需要做某事。在本句中need作實(shí)義動(dòng)詞用，對(duì)其否定需要借助助動(dòng)詞do。所以選B。
