八年级上册第二单元Topic 3 SectionA-B一、重点句型及知识点讲解1. May I ask you some questions, Dr. Li ? ---- Sure, go ahead. 我能问你一些问题吗,李医生?当然,请问吧。
(1) 1)疑问句和否定句中,表“一些”,常用any, 不用some. 但当此疑问句表建议或请求时,Some不改成any. 如:Would you like some tea ?2)question意为“问题,疑问”,指较易解决的问题及口头回答的问题。
如:Can you answer the question?你能回答这个问题吗?【辨析】problem和question都当“问题”讲,但它们是有区别的。
Problem 通常指难以解决的问题,尤指比较困难的问题,如社会、政治和经济等。
与它搭配的动词一般是work out或solve;而question常指对某事疑惑不解需要寻找答案的问题,它常与动词ask或answer搭配使用。
如:We must solve the problem of heavy traffic in Beijing as soon as possible.我们必须尽快解决北京的交通拥挤问题。
This is a difficult question to answer.这个问题很难回答。
(2) Sure , go ahead 当然可以,请问吧!Go ahead.(口语)表示同意对方的请求,根据情况可译为“说吧”!“做吧”! 如:__Can I read the sports section ? 我可以看看体育版吗?__Yeah, go ahead.请看吧!【拓展]】(1)go ahead and do sth .赶紧做某事。
如:Go ahead and eat before everything gets cold.趁东西还没凉赶紧吃。
(2)go ahead of 在……之前去。
