Question

帮忙做下英语题，谢谢

If it hadn't been for your help，我们不可能在这门短的时间里就在这实验上取得成功（couldn't have done).题目要求根据括号内的句式翻译。我自己翻译的是
（we couldn't have a succes in experiment that such a short time）对不对，请指教？

Answer 1

如果没有你的帮助，我们不可能在这门短的时间里就在这实验上取得成功。
If it hadn't been for your help, we wouldn't have succeeded in the experiment in such a short time.

你翻译的不错，a success 最好改成 succeeded，这样比较地道点。
然后英文里一般都是 if it hadn't been / wouldn't have... 所以把 couldn't 改成 wouldn't.

这样就 perfect 了。 希望对你有帮助—— ♥

Answer 2

建议改为：we couldn't have succeeded in the experiment in such a short time.
题目要求用couldn't have done的句式，done是要用动词的过去分词，而你的句子中用的是名词success，不符合题目的要求，应该用动词succeed 的过去分词。
另外， experiment要用定冠词，在这门短的时间里是in such a short time

Answer 3

we couldn't have succeed in the experiment in such a short time
