英语的,请问,下面句子可以在 COSTS 后面加 TO 句子有错误吗?
Developing countries should try their best at all costs establish advanced laboratories for monitoring of quality
英语的,请问,下面句子可以在 COSTS 后面加 TO 句子有错误吗?Developing countries should try their best at all costs establish advanced laboratories for monitoring of quality
正确答案为:
要加to.
try best at sth 这里没错,
然后 establish 也是动词,那么就要用to来连接.
Developing countries should try their best at all costs to establish advanced laboratories for monitoring of quality
可以加 to
这 to 是try their best 后要用的
...........try their best (at all costs) to establish............
at all costs前后都有逗号吧,这样后面加TO没问题啊
