5. He was just about to say something when Peter turned
around.
他正要说些什么，这时皮特转过身来。
be about to do sth. 正要做某事，表示该动作马上就
要进行，不能与时间状语连用。
[误] He was about to leave in five minutes.
[正] He would leave in five minutes.
他5分钟后离开。
when 在此表示“正在这时 / 那时，突然”(具体用法详
见Chapter 1“词汇短语”)
4. If only they could find a way to get to the room,
behind the wall.
要是他们能找到办法到达墙后面的房间，那就好了。
if only虽然是从属连词，但它引导的从句却能单独
成句，且能表达完整的意思：要是……该多好 --
种不能实现或难以实现的愿望。它相当于wish，但
语气更强。句后用句号或感叹号皆可。
① 表示已过去了的不能实现的愿望，常含有后悔、惋
惜之意。谓语动词应使用had done形式。
If only I had taken his advice!
要是我听从了他的建议就好了!
② 表达现在不可实现的愿望，谓语动词用一般过去
时。
If only I could swim!
我要是会游泳该多好!
③ 表达将来难以实现的愿望，谓语动词用would /
could + 动词原形或一般过去时。
If only she would help me!
要是她能帮我就好了。
[注意] if only 除以上用法外，它还相当于if，引导条
件状语从句。
④ If only he gets the job, it will make a great deal of
difference.
要是他能得到这份工作，情况就大不一样了。
[辨析] if only与only if
if only 多用于虚拟语气；only if 多用于陈述语气，
only 修饰 if，表示惟一的条件。
3. You want t0 find a good song to dance to.
你想找一首好歌来伴舞。
① to dance to 是不定式作定语，修饰名词song，并与

词不及物，则应加上适当介词。如：
New York is a nice place to visit.
纽约是个游览的好地方。
Could you find me a chair to sit on?
能给我找把椅子坐吗?
② dance to中的to表示“伴随，按照”。如
He likes to sing to the piano.

2. You want to buy a CD for your friend's birthday but

他确信这次聚会能获得成功。
[注意] be sure 后接名词、代词、动名词时需用介词of

定。
[比较]be sure to do 与 be sure of doing
说话人确信约翰能通过考试。
John is sure 0f passing the exam.
约翰本人确信自己能通过考试。
[提示] be not sure后常用whether / if, what, when,
where 等引起从句，有时也用that。如：

我拿不准他是否会来看我。
I was not sure what I ought to do.

我们队肯定能赢得这场比赛。(不用sure)
