Ellipsis in Compound Sentences
Ellipsis is the omission of one or more words from a sentence, usually because the information has already been provided in the same sentence or because it is understood in the context. In order to read English well, you must know how to recover the words that are omitted. See if you can supply the missing words in the following sentences.
1. He is going to Japan, but his sister to America.
2. We can and will achieve these goals.
3. Are you coming or not?
4. I would like to go with you, but not with him.
5. In 1995, the number of the convenience stores increased from under five hundred to one thousand, and in1999, to over two thousand.
現代英語的特性是力求簡潔，因此在符合習慣以及不致造成誤會的前提下，常將重複的部分省略。句子有所省略，常是我國學生無法讀懂英文句子的關鍵所在。本課介紹的是合句 (compound sentences) 中常見的省略，練習目的在訓練學生將省略部分還原，以確實掌握句意。接下來兩課將繼續練習其他的省略句。省略的大原則很容易（省略重複部分），但實際的細則略顯繁複。本單元的重點在培養學生閱讀能力，練習補上省略的字詞，以切實了解句意，因此教學時不需要求學生死記省略句的規則，要讓學生盡量用常識判斷被省略掉的部分。對等子句的省略常見的原則有：
1. 以對等連接詞and, or, but連接的對等子句，可將與前面子句相同 之主詞、動詞省略。如1, 3, 4, 5題。
3 介詞片語中的介系詞通常也不省略，如第1題的to，或如： I work in a factory and my brother(works) on a farm. 第5題的to也是如此。
4. 前後子句裡的助動詞不同而主動詞相同，通常將前面子句裡的主 動詞省略。如第2題 (achieve), (we)。
5. 前後子句的受詞若相同，通常省略前句的受詞。如第2題 (these goals)。
1. He is going to Japan, but his sister (is going) to America.
2. We can (achieve) [these goals] and (we) will achieve these goals.
3. Are you coming or (are you) not (coming)?
4. I would like to go with you, but (I would) not (like to go) with him.
5. In 1995, the total number of the convenience stores increased from under five hundred to one thousand, and in 1999, (the total number of the convenience stores increased) to over two thousand.
