1．I think it would be a good idea to have comments from secretaries and typists who are already using it．听听使用这种计算机的秘书和打字员的意见，我认为是个好主意。
I think it would be a good idea to do sth．（我想干某事是个好主意。）这是委婉地提出建议的会话用语。例如：
A：I'm afraid I'm puttig on weight．我恐怕在发胖了。
B：I think it would be a good idea to keep on doing morning exercises．坚持做早操，我想是好的。又如：
A：I haven't got any information on this matter．关于这件事我没有得到任何消息。
B：I think it would be a good idea to ask your secretary．去问问你的秘书，我看是个好主意。
2．Do you think so？你是这么想的吗？
这是含蓄地表示不同意的用语。例如：
A：What do you think of Bob？你觉得鲍勃怎么样？
B：Perhaps he's nice，but he's very quiet．He seldom says anything．也许他很不错，但是他很沉默，很少说话。
A：Do you think so？Do you think he doesn't like talking？There he comes，talking with friends．Look，how cheerful he is！你是这样认为的吗？你认为他不喜欢说话吗？瞧，他来了，在跟朋友聊着呢。你看他有多高兴！
如果这里用I don't think so．来代替Do you think so？就会显得这个人说话硬梆梆的，缺乏涵养。
