问题描述：
-Will you please show me how to operate the new machine?
-Sure.It's a piece of cake.Now let me tell you ____ to do first.
a.what
b.how
c .whether
d.which
为什么选a而不是b,what和how在这种题里面如何选择.
答
tell 后面 接的是what引导的宾语，what to do 是完整的。如果用how的话 应当是 how to do it
答
what to do
因为what 已经做宾语了，所以后面不用加it
how to do it
而how的话后面是要加宾语的。
答
1.选a
2.选what可翻译为“现在让我告诉你先做什么”,如果选how,这个句子中tell后面的宾语从句就少了一个主语it,应该是Now let me tell you how to do it .
