1. 增加并列成分;
2. 增加修饰成分;
3. 增加从句;
4. 增加连词;
如以下例句：
They grow long hair.
这个句子没有任何闪光点，我们利用以上扩充方法来修改这句话，变成了如下的句子：
They grow long hair, regardless of the gender, usually part of which is dyed in gold.
这句话就相当璀璨夺目，有修饰成分，也有从句。
同理，做以下的三个练习：
1. They wear jeans.
They wear jeans in each and every season, commonly knees of which are deliberate torn.
2. Boys wear earrings.
Boys are keen on earrings and other weird ornaments.
3. Girls smoke.
Girls are fond of Marlboros or some odd bad words.
以下为一组多个句子组成的一段话。
Energy is much needed now. And nuclear plants are clean and economical. They can producevast amounts of energy. But people, especially local residents are very concerned aboutsafety. They hold a strong negative attitude toward them.
我们可以看出，这些句子都是简单句，虽然表达的意思很清楚，但是明显没有满足ETS的口味偏好，下面我们将上述句子搭配成完整的复杂句。合并句子的准则为：同一个词汇可以合并，变成从句或修饰成分，例如“energy”、“people”。修改后的句子为：
Nuclear plants are a clean and economical way of producing vast amounts of much-neededenergy; however people, especially local residents, who are very concerned about safety, holda strong negative attitude toward them.
同理，做两个练习：
修改前：Some people succeed. Other people fail. The difference is not the number ofopportunities. It is whether they can take advantage of opportunities. Opportunities will arisein the course of one's life, though they are rare.
修改后：One essential difference between those who succeed and those who fail is the extentto which they take advantage of opportunities rather than the number of opportunities, whichwill inevitably arise, if rarely, in the course of one's life.
修改前：College students now are primarily interested in grades and economic success. They areexpected to cheat more frequently. They are unlike those graduated ten years ago. They areonly interested in their own personal future and consider little the problem of society.
修改后：College students, primarily interested in grades and economic success, are expected tocheat more frequently than those who graduated ten years ago and are far less concernedwith the problem of society than with their own personal future.
综上所述，我们应该大致知道了如何扩充句子了。小站教育希望大家合理扩充句子，同时也提醒大家，只要我们不断积累，用心把握每一个细节，就一定能在托福考试中取得好的成绩！
