以前在台湾打排球都是在水泥地上打, 可是来到美国, 我发现他们更喜爱沙滩排球或是草地排球 (拿一个活动的网子, 在草地上一挂就玩起来了) 玩的很随兴很自在,  这通常也是 party 的一个重要部份.  Come off 简而言之就是二个原来在一起的东西分开的意思, 如油漆剥落, 如 The paint comes off gradually. 或是球被球棒击中, The ball comes off the bat.
 
7. I hope someone comes by and picks us up.
我希望有人经过然后让我们搭便车.

有一次大热天跟一个美国的朋友走在柏油路上, 他大概是被晒昏了吧. 居然开始作起白日梦起来, I hope someone come by and pick us up. 结果呢? 当然是没有人会理我们的啦, 还是要自己走回家. Come by 算是常见的片语, 就是从旁边经过的意思.
 
8. We haven't come to a conclusion yet.
我们还没有得到结论.

Come to 常可以见到在这样的句子中, 如得出解答 (come to a solution) 或是得到结论 (conclusion) 和 come up with 不同的是, come to 指的通常是最终的结果, 而 come up with 只是想到某个想法而已.

Come to 也常用于来到某个地方, 例如 You will come to a stop sign if you keep straight. 如果你直走的话, 你就会到一个 stop sign.
 
9. This factor doesn't come into play in this case.
这个因素在这里不起任何作用.

Come into 后面可以加一个名词来表达不同的意思. 如例句中所讲的 come into play 就老师上课时喜欢用的片语之一. Come into effect 跟 come into play 很类似, 所以这句话也可以说成, This factor doesn't come into effect in this case.
