1.A is not necessarily the reason of B.
2.B is not necessarily the result of A.
在写作时，既可以选择其中一个路径写，也可以选择两个路径，同时从两个方面展开文章。针对题目“Advertisements are a waste of money and time of a company because consumers know what they want to buy广告浪费公司的时间和资金（结果，用B表示），因为消费者知道他们想要买什么（原因，用A表示）”，我们从“A不一定会导致B”这个路径着手，即，因为就算消费者知道自己想要买什么，很多人在看了广告之后，也会临时做出购买的决定等，所以最终公司在广告上花费的时间和资金并不能算是浪费，这样，文章会比较好写。
Do you agree or disagree with the following statement? Television has destroyed communication among friends and family. Use specific reasons and examples to support your opinion.
这个题目很典型，虽然题目中没有出现表示因果关系的词语，但我们可以构造出因果关系。有三个点：1.spend too much time on watching television，所以2.spend much less time on communicating with friends and family，所以3. destroyed communication among friends and family，这是题目暗含的内容，如果你把题目摆成这样子，就摆成了因果关系的情况，这个就叫做构造因果关系法。
As an old saying goes, every coin has two sides. Likewise, television has both its advantages and disadvantages. Spending too much time sitting alone in front of TV and therefore leaving little time for communication is its potential harm faced by everyone. Yet it is too hasty to reach a conclusion that television has destroyed communication among friends and family.
On the one hand, watching TV is not necessarily the reasonfor the failure of communication. To my thinking, the most important factor influencing communication should be the people involved.Personality plays an important part in this. A sociable and extroverted person will always cherish the time spent with other people, either friends or family, and even acquaintances; to ask him sit alone in front of TV too long is like to lift a fish out of water: both are against their nature and would be unpleasant. In a similar fashion, an anti-social and introverted person will not communicate more even when they are surrounded by a lot of people. If the people involved are against accompaniment, they will always find a way to avoid communication. Even if there is no TV, there are bound to be other distractions, being computers, books, radios or other devices.
On the other hand, TV doesn’t necessarily lead to the decreasing of communication.On the contrary, it may sometimes enhance communication by providing people with more common information to share and to discuss. Adidas’s famous catchword “Impossible is Nothing” is widely used when people want to encourage themselves or their friends. TV series are always the center of people’s conversation especially when they are first being shown. Two housewives can talk about some advertisements broadcasted on TV when they decide to buy some extra furniture. If you want, TV can always offer you some information to start a conversation.
To summarize, I truly don’t think that TV has destroyed communication between friends and family.
