说明
take turns/in turn
核心问题
If we ____, we won't get tired.
A. to take driving by turns B. drive in turns
C. take each turns driving D. take turns driving
我选了 B。因为 in turns 作“轮流地”解，作 drive 的状语。
词典解答
选 B 是错误的。你选了 B, 可能是你误把 in turns 当作是 in turn 了。in turn 才作“轮流地”解。例如：
-
Each of us collects the mail in turn/by turns. (CIDE) 我们每个人轮流取信。
-
She went round the ward, talking to each woman in turn ... (Cobuild) 她查看病房，轮流和每个妇女谈话……
此题的正确答案是 D。take turns doing sth. 是“轮流作某事”的意思。例如：
- You can take turns paying for evening functions ... (Cobuild) 你们可以轮流支付晚餐
的费用……
- They took turns watching the baby. 他们轮流照看婴儿。
[试题句意]如果我们轮流开车,就不会弄得很疲劳。
