阅读下面的短文，并根据短文后的要求答题（请注意问题后的字数要求）。

     An American friend of mine who was high up in a big corporation had worked out a way of handling a

flood of e-mails before most of us had even heard of the concept. If any information he was sent was vital

enough, his lack of response could ensure the sender rang him up. If the sender wasn't important enough to

have his private number, the communication couldn't be that important. My friend is now even more senior

in the same company, so the strategy must work.

     Almost every week now, there seems to be a report suggesting that we are all being driven crazy by the

bother of e-mail. If this is the case, it's only because we haven't developed an appropriate discrimination in

dealing with it.

     ______. Firstly, you junk anything with an exclamation mark or a string of capital letters, or from any

address you don't recognize or feel confident about.

     Secondly, e-mails don't all have to be answered. Because e-mailing is so easy, there's a tendency for

correspondence to carry on for ever, but it is permissible to stop an endless discussion or to accept a point

of information sent by a colleague without acknowledging it.

     Thirdly, a reply e-mail doesn't have to be the same length as the original. We all have e-mail pals who

send long, chatty e-mails, which are nice to receive, but who then expect an equally long reply. The charm

of e-mail can consist in the simple, incomplete sentence, totally regardless of the format of the letter sent by

post. You are perfectly within the bounds of politeness in responding to a marathon e-mail with a brief reply.

1. Which sentence in the passage it the closed in meaning to the following one? The possible existence of

annoyance results from our inability to sort out e-mails.
