■有各種各樣的書(即書有好壞之分)。

誤：There are books or books.

正：There are books and books.

析：用 and 連接兩個相同的名詞，可表示“許多”或“有各種各 樣的”(即有好的也有壞的)。又如：I waited for hours and hours.(我不知等了多少個小時)。

■他說得既不清楚也不正確。

誤：He didn’t speak clearly and correctly.

正：He didn’t speak clearly or correctly.

析：在否定詞之后兩者均被否定的成分要用 or 連接而不用 and。誤句的實際意思是：他沒有說得既清楚又正確(部分否定)。

■要是他這樣說，那他就是個騙子。

誤：If he said so, and he is a liar.

正：If he said so, he is a liar.

析：if 引導的是條件狀語從句，其后的為主句，其前不能用并列 連詞 and(否則全句為并列句)。

■他寫過許多書，大部分都很受歡迎。

誤：He wrote a lot of books, and most of them being popular.

正：He wrote a lot of books, most of them being popular.

正：He wrote a lot of books, and most of them were popular.

正：He wrote a lot of books, most of which were popular.

析：有 and，全句為并列句，and 后的句子應有完整的謂語。若無and，則全句可能為簡單句(如用 being 的一句)或復合句( 如用 which 的一句)。
