e.g. Though they managed to start the car in the beginning, yet they got in trouble soon. 虽然一开始他们成功地发动了车，但是很快他们就陷入麻烦了。新概念2composition

by no means 决不，绝对不 （加强语气）

e.g. It is by no means pleasant to take a crowded bus.乘坐一辆拥挤的公交车无论如何不是一件令人高兴的事。

by no means=not… by any means=not at all 一点也不

e.g. He isn’t satisfied with the job at all. = He is not satisfied with the job by any means.

总结表示“决不”的词组：

in no way\in no case\in no sense \in no circumstances\ on no account\ at no time\ by no means

表示“命名”的词组：be named after\be named for\take one’s name from
