such as a, b or c 与such as a, b and c, 两种表达都可以说,但有区别。在一类事物中,虽然such as 列举的内容仅是其中一部分,但前者强调个体概念,后者强调累加概念。请比较:
1. I know many of the boys, such as John, Peter and Tom.
我认识很多男孩子,例如约翰、彼得和汤姆。
Any of the boys, such as John, Peter or Tom, can lift that stone.
任何男孩子,如约翰、彼得或汤姆,都能举起那块石头。
2. Many letters in the alphabet, such as b, c and d, are consonants.
字母表中的许多字母像b,c,d等都是辅音字母。
You can’t pronounce these consonant letters as vowels, such as b, c or d.
你不能把这些辅音字母发音为元音,例如b, c 或d 等。
