1 spiral out of control  急剧上升，失去控制

Will people's handwritig suffer if they use computers too much?

I think this is a very topical subject. A lot of young people these days almost solely use computers to write script or correspond with friends. If this continues they could lose the ability to write script by hand! What's more, they often use emotions or abbreviations like LOL, or replace words like 'you' with a single letter. This problem is spiraling out of control. 我认为这是个很典型的例子。很多年轻人几乎只用电脑做功课或者和朋友沟通。如果这样继续下去的话，他们很有可能会丧失书写能力。更糟糕的是，他们经常会使用一些表情符号或者缩写如“LOL’。或者仅用一个字母来代替像是 'you'之类的整个单词。而且这个问题正在急剧恶化。

2 to be in dire straits 深陷绝境

What are some problems caused when too many people move to the city to find work?

I think there are a host of difficult situations which arise from this. The first problem of course is overcrowding, which creates a burden on our transportation system. Another result of overcrowding is an increase in housing costs. To tell the truth, I think this problem is becoming worse day by day. If the government doesn't put some controls in place, we're gping to be in dire straits! 我觉得会引起很多棘手的问题。第一个是太过拥挤，造成交通压力。另外过度拥挤也会提高住房成本。说实话，我认为这个问题正在日趋恶化。政府部门如果不采取一些调控措施的话，我们将会深陷绝境。
