In the last decades,advances in medical technology 如下
In the last decades,advances in medical technology have made it possible for people to live longer than in the past.
made it 后面要不要加个 is 既 made it is possible?为什么?
Before giving my opinion,I think it is important...
这里用giving 是因为前面的before 能否改成 I give?
Although this view is widely held,this is little evidence that education can be .
虽然这个观点被广泛接受,但是很少有证据证明教育可以.是不是应该改成there is?为什么是this is?
It is indisputable that there are million of people who still have a miserable life.这里的who可以去掉吗?为什么?
It is more important to buy the cheapest food possible in large quantities to make a higher profit.这里 in large quantities 是相当于副词吗?大量地?那possible不应该也是副词吗?改成possibly修饰buy?
The only extra expense I have to pay is the time it takes for me to cook the food.这句话对吗?感觉好别扭 it takes sb time to do sth 我都不知道怎么问.
I have a sense that i did not waste the time so much as I truly enjoyed life for an hour at the end of the day.在一天的结束之际,真正享受了一小时的生活使我感觉自己并没有浪费时间.这里是so much as 用法 还是 so much修饰time as 属于后边的?如果是前者,就不懂了,
