time they spend on the Internet.

have no control over:

表示身体部位的单词短语常被用作比喻意义，如 red-handed 和 pay lip service 等等。失去控制也可以用一个跟身体部位有关的短语来表示，那就是 out of hand，其中的 hand 跟前面两个的用法类似，例如：
red-handed 现场抓获的
The murderer was caught red-handed.
凶手当场被抓获了。
(pay) lip service 口惠无实
Is this a real promise, or is this just lip service?
这是一个真正的承诺，还是只是口头上的承诺？
out of hand 失去控制
Things got a little out of hand at the party and three windows were broken.
聚会上情况有点失控，三扇窗户被打破了。
He went to see his doctor because he felt his drinking was getting out of hand.
他去看医生，因为他觉得他的酒量失控了。

他们的孩子需要一些管教，他们完全失控了。
Two of the children started fighting in the playground yesterday. It wasn’t long before it all got out of hand.
昨天有两个孩子开始在操场上打架。没过多久一切就失控了。
类似的习语数不胜数。由此可见英语知识远比我们想象的阶段知识来得丰富多彩，我们平时要多积累学习。那么在”控制之中“怎么表达呢？
control 常与介词 in 或 under 连用来表示在控制当中或处于掌控中，或者我们还可以用 have control of (over) sth，例如：
under control:
The situation is under control.
局势已经得到控制。
It took two hours to bring the fire under control.
花了两个小时才控制住火势。
I've got everything under control.
一切都已在我控制之中。
in control (of):
Who's in control here? I want to talk to the ranking officer.
这里谁负责？我想和高级军官谈谈。
Your mother was terrified when she first learned to drive, but now she is completely in control behind the wheel.
你妈妈刚学会开车时很害怕，但现在她完全掌握了方向盘。
have control of (over) sth:
Some teachers have more control over pupils than their parents have.
有的老师比小学生的父母更能管得住他们。
Parents should not have control over their children.
父母不应该控制他们的孩子。
那么如何表达能否控制住呢？我们常用动词 get，keep 和 bring 来表示控制得住或不造成伤害，例如：
Please keep your dog under control!
请管好你的狗！
It took two hours to bring the fire under control.
花了两个小时才控制住火势。
Firemen said they had the blaze under control.
消防队员说他们已经控制住了火势。
就像上面提到的，英语很多单词都有很多的用法，它们不但有多词性，而且意思还丰富多彩，就像家喻户晓的 free，它常被用作形容词，表示自由的，但实际上它还可以用作动词。
因此在实际的学习中要根据自己的能力，通过重学已经学会的单词使自己的词汇量“增加”。大家都知道的用法不常考，只是额外的努力让你独树一帜。
