英语句子什么意思？

Question

1.The cake won't rise.because there is not enough flour.
下面是个填空题：
There are _____ students to take the class.选项是enough和not enough,正确答案是not enough，填enough不行吗？
“既然enough是错的，那我想表达有足够的学生来上这个课怎么说？”

Answer 1

There are not enough students to take the class.
该句的意思应该是：学生人数不够，所以该课无法开展。

The cake won't rise.because there is not enough flour.
面粉加少了，所以蛋糕没有做成。
rise cake是做蛋糕的意思。句中用了被动态。

什么叫“有足够的学生来上这个课”？仔细想想，很难理解。这个课一定需要一定数量的学生吗？如果是，那么学生数量不够，该课就一定不能展开；如果不是，那就根本不存在“有足够的学生来上这个课”的说法。剩下的就是“有足够数量的学生了，所以课可以开始了”：there are enough students,so that the class can be taken.

Answer 2

1.The cake won't rise.because there is not enough flour
由于面粉不够了，蛋糕不能发酵了。

第二句，我也说不上来是啥原因，习惯说法就是not enough

Answer 3

由于面粉不够，蛋糕不会发酵的。
enough是错的。整句的意思是：选这门课的人数不够。

Answer 4

the cake won't rise. because there is not enough flour就是蛋糕没有做成因为没有足够的面粉
你要根据那个列句做题目，所以下面的题目就要选enough了
但如果列句是there are enough flour to make a cake,你就可以写there are enough students to take the class
