下面这句摘自高中英语新教材人教版必修一 p3:
Work in groups.
Choose one of the situations and make a conversation.
请问这里的 in groups 可以换成 in pairs 吗?
句中的 in groups 可以换成 in pairs,但意思不同:in pairs 指两人一组,in groups 指两人或多人一组(意思是“按小组”“以小组为单位”“三五成群地”“三三两两地”等)。如:
▲in pairs
The children work in pairs. 孩子们两人一组进行活动。
The desks were arranged in pairs. 桌子两张两张地排列着。
Do the next exercise in pairs. 下一个练习两人一组进行。
These earrings are only sold in pairs. 这些耳环只能成对出售。
指两人一组时也可用 in twos。如:
You will be working in twos. (=in pairs) 工作时你们将两两结对。
类似的还有 in threes, in fours, in fives 等。如:
The students are lined in fives. 学生们五人一排。
You can walk in pairs or in fours. 女孩子们或两人或四人一组走。
▲in groups
Men stood in groups on street corners. 一些男人三五成群地站在街角上。
The children were put in groups by age. 孩子们按年龄分成组。
Guests arrived singly or in groups. 客人有单个来的,也有三三两两一起到的。
The birds can be seen singly or in groups. 这种鸟既可以看到单只的,也可以看到成群的。
Students can work individually, in pairs, or in groups. 学生们可以单独、成对或分组工作。
用 in groups 时,若要具体表明是几个人,则可以用 in groups of…来表示。如:
If we work in groups of three there won't be an odd one out. 如果我们三人一组干活,就不会有人剩下。
To save time, students will be examined in groups of three. 为节省时间,学生将三人一组接受考试。
We were warned not to walk in the mountains except in groups of five or more. 有人提醒我们,没有五人或五人以不要在山里行走。
