如：
More and more students have taken to depend on their parents to make decision for them。
这里的 take to means to begin to do sth as a habit 其中 to为介词，所以后面只能接名词或相当于名词的词，如动名词。所以黑体处应改为depending on。take to的另一个常用用法也需要牢记：
He hasnt taken to his new school. (这里take to means to start liking sb or sth)
Prefer A to B中的 to也是介词，会有 prefer doing sth to doing sth/ prefer sth to sth else, 这里朗阁海外考试研究中心提醒您，prefer to do sth rather than do sth中的to可是真正的不定式符号。
类似的常用用法请同学们牢记：
Be used to doing
Be accustomed to doing
See to doing
Adapt to doing
Adjust to doing
prefer doing sth. to doing sth。
等等，请注意平时仔细积累。
三、assume及claim使用不够准确
我们知道， think, assume, claim是议论文中常用引出观点的动词。在实际作文中，同学们往往认为几个词的意思是一样的，完全可以代换，所以拿过来就用。甚至还有同学把consider也拿过来与之混用。我们首先还是从定义来看这几个词的不同：
Think: to have opinion or belief about sth。
翻译为认为，通常接宾语从句来表达比较确定的观点。
Assume: to think or accept that sth is true but without having proof of it。
翻译为假设、假定，是否有事实依据是不确定的。
Claim: to say sth is true although it has not been proved and other people may not believe it。
翻译为声称，用这个词往往意味着不赞同紧跟其后的观点，所以很少用作 I claim that
Scientist are claiming a breakthrough in the fight against cancer, but in fact, 。
