单一的句式，有时候虽然也能勉强表达出作者的思路，但读起来不免令人乏味。为了增强文章的趣味性，导师建议考生还应该注意句式多样性的变化：

1. Berlin states that both positions harbor the same fallacy.

这句话平铺直叙，但是假如我们使用插入语的话就会使其生动得多。比如：

Both positions, ironically enough, as Berlin points out, harbor the same fallacy.

2.Teenagers are pressured by schoolwork. They are encouraged by their peers. They have to resort to smoking like adults. But sometimes they feel a little guilty.托福考试

虽然这四个简单句都能围绕一个主题，但是给人的印象是作者的思路很乱。其实我们可以用一个长句来把这个问题说得很清楚：

Teenagers, pressured by schoolwork and encouraged by their peers, often resort to smoking like adults, though they feel a little guilty.

3.Some people succeed. Other people fail. The difference is not the number of opportunities. It is whether they can take advantage of opportunities. Opportunities will arise in the course of one’s life, though they are rare.

上面这段话由5个简单句组成，结构上显得不够紧凑。我们可以通过把简单句合并成复杂句的方式(运用定语从句，同位语从句，插入语等)，把这5个句子有机地结合起来。如下所示：

One essential difference between those who succeed and those who fail is the extent to which they take advantage of opportunities, rather than the total number of opportunities, which will inevitably arise, if rarely, in the course of one’s life.

4.College students now are primarily interested in grades and economic success. They are expected to cheat more frequently. They are unlike those graduated ten years ago. They are only interested in their own personal future and consider little the problems of society.

上面这段话读起来令人乏味，但若运用定语从句以及插入语对其改写，就会让人回味无穷。如下所示：

College students, primarily interested in grades and economic success, are expected to cheat more frequently than those who graduated ten years ago, and are far less concerned with the with the problems of society than with their own personal future.

5.Energy is much needed now. And nuclear plants are clean and economical. They can produce vast amounts of energy. But people, especially local residents are very concerned about safety. They hold a strong negative attitude toward them.

上面这段话读起来有点零乱。我们可以用插入语，因果关系和定语从句的形式，把简单句合并成复杂句。如下所示：

Nuclear plants are a clean and economical way of producing vast amounts of much-needed energy, though people, especially local residents, who are very concerned about safety, hold a strong negative attitude toward them.
