1. Ed要符合你的要求。 2. 他要與他人競爭。 3. 他要維持良好信譽。 4. 他必須更加努力。
可組成：(In order) to meet your requirements, to compete with other people and to maintain a good reputation, Ed has to work very hard.
(用三個不定詞to meet …, to compete ...to maintain成為平行片語”parallel”) (in order在句首可省去)
1. Gas prices are skyrocketing. 2. Food costs are going up. 3. bob tries to tighten his belt. 4. He buys inexpensive foods. 5. He rides his bike to work to keep his costs down.
1. 汽油價格暴漲。 2. 食品開支也升高。 3. Bob想要縮緊腰帶。 4. 他購買便宜食物。 5. 他騎單車上班要減少開銷。
可組成：Because of skyrocketing gas prices and high food costs, Bob buys inexpensive foods and rides his bike to work in order to keep his costs down and (to) tighten his belt.
(這裡用的是介詞片語because of ...和不定詞片語in order to keep...)( 這時in order不要省去)
(5)使用從屬字或附屬字(subordinator)使句子成為附屬句。組合後，更加合理。
附屬字指時間時，多半用：after, before, when, while, whenever, until, since, as, no sooner...than...,as long as, as soon as等。
指原因時，多用：because, since, although, even though,指其他事物時，用： if, in case, once, whether or not等。
只要意義合乎logic，都可把句子組合起來。
例如：
1.The students are protesting. 2. The tuition was increased 20%
1.學生在示威。 2. 學費增加百分之廿。
可組成：
The students are protesting because the tuition was increased 20%
( because the tuition was ...成為附屬句。增加because後，句子意義也較完整)
1. Big Chinese cities like Shanghai and Beijing can do well. 2. They can overcome crime and pollution.
1. 中國大城市像上海、北京可以安然無事。 2. 他們能克服犯罪和污染。
可組成：
Big Chinese cities like Shanghai and Beijing can do well if they can overcome crime and pollution.
( if they can...成為附屬句。增加if後，句子意思較完整)
1. Graduates in liberal arts majors have difficulty (in) finding jobs. 2. They are willing to accept jobs outside their majors. 3. The economy improves.
1. 主修人文學科的畢業生找工作不容易。 2. 他們願意接受行外工作。 3. 經濟好轉。
可組成：Graduates in liberal arts majors have difficulty finding jobs even though they are willing to accept jobs outside their majors until the economy improves.
( even though they are...和 until the economy improves都是附屬句。增加「即使」even though 和 「直到」until後，句子意思更加連貫完整)
1. Publishing traditional books has become less profitable. 2. There is keen competition from E-reading. 3. Many young people do not buy books.
1. 發行傳統書籍成為較少利潤。 2. 「電子閱讀」是很大競爭對象。 3. 許多年輕人不肯買書。
可組成：
Since many young people do not buy books with keen competition from E-reading, publishing traditional books has become less profitable.
(句前加上since有「由於」或「因為」的意思，所以 since many young people... 成為附屬句，把主要句子publishing traditional books...放在後面)
1. Many Americans still suspect acupuncture.
2. The Chinese have used it for thousands of years.
3. The method is strange to the American ways of medical treatment.
4. Not too many Americans have benefited from its effects.
1. 許多老美對針灸仍有疑慮。 2. 老中已用針灸數千年。 3. 針灸法對老美醫療方式而言，有些奇怪。4. 沒有很多老美對針灸得到效益。
可組成：
As long as many Americans have not benefited from its effects of this medical treatment, strange to the American ways, Americans still suspect acupuncture although the Chinese have used it for thousands of years.
(首句加上as long as......「只要」...變成附屬句。strange to the American ways是形容詞片語，修飾 treatment)
( although the Chinese... 又是另一個附屬句，真正主要子句是Americans still suspect acupuncture)
1.We should not worry about nuclear plants. 2. Nuclear plants can possibly be risky.
3.We should be very careful in using them. 4.Nuclear plants can save energy.
1.我們不必擔憂核電站 2.核電站可能有危險。 3.我們必須小心使用核電站。 4.核電站可節省電力。
可組成:
We should not worry about nuclear plants because they can save energy and while they can possibly be risky, we should be very careful in using them.
(加上because they can save---和while they can possibly...使兩句成為附屬句，而兩句主要子句是we should not worry about...和we should be very careful...) (句中的they與them都是指核電站)
(未完待續)
