task two
opening para is ok
body1 is good, but it could be better if you use one concrete example
body 2's topic sentense is poor. This sentense seems ominipotent, however, it is vague. It says nothing about the main idea of this para. So it is better to substitue it with another one.
"As I know,people who want to put all of their money on the lottery is seldom."
The above sentense is problematic in grammar. We cannot say" people is seldom". I suggest you to change it into" few people invest all their wealth on the lottery "
Actually the whole body 3 is not very supportive to the topic. It doesnt conduce to the idea that lottery has benefits. In body 3, you are just describing facts but not explaining the benefits.
Please note the topic"The lottery does more good than harm. Discuss."
This topic asks you to analyse the advantages and disadvantages of lottery to the society and individuals. But first of all, you should emphasize on its effects on the society.
For example, lottery may trigger people's lust for gambling, thus, gives birth to many hidden instable elements to society.
This topic requires you to discuss and compare the good aspects and harmful aspects and eventually gives your conclusion based on the comparison. Therefore, it is not convincing to conclude without any comparison.
