On the other hand, opponents of factory farming say that it is cruel to the animals.For instance, many farm animals are kept in small spaces where they can hardly move.People who fight for animal rights claim that these animals suffer terrible stress.In addition to this, factory farming has a negative impact on the environment because it creates a lot of waste products, and uses a lot of chemicals to control insects and drugs to treat diseases (UK Farming Today，2013). To sum up, despite producing cheap food, factory farming is bad for the planet and for the animals themselves.In my opinion, we should try to reduce this kind of farming, although we would have to pay more for our eggs and meat. 写作手法 【文章结构】 1．本文有四段，分为三部分 2．本文采用了一般现在时和比较的写作形式。 3．写作步骤是：提出问题→列举两种不同的观点→对比两种观点。 【相关词句】 1．开头语 ①The topic of(本文factory farming)...is becoming more and more popular recently. ②Factory farming(本文topic)plays an important role in... 2．双方观点和理由 (1)赞成方 ①...hold the opinion that it provides more food (factory farming)... ②...are in favour of (factory farming)... ③...approve if... ④...agree to...

Some think the creative measures should be put into practice, saying that the use of high technology can add beauty to the Palace Museum and make it more attractive to visitors.However, those who are against the idea say that it will destroy the original appearance of the Palace Museum.More importantly, it is extremely essential to respect the history, tradition and culture, which provide foundation for our civilization. In my opinion, we should use high technology properly to beautify the Palace Museum and it's our duty to provide a complete and true ancient palace for the world. 最近，你们针对“是否应该帮助陌生人”展开了讨论，同学们就这一话题意见不一，你的看法如何？根据所提供的信息，以“Should We Help Strangers？”为题，写一篇短文。 观点 原因 赞成 帮助他人是美德； 帮助他人就是帮助自己 …… 反对 怕陷入麻烦；怕被误解 …… 你的观点？(至少两点) 注意：1. 写作词数应为80左右(正文的开头已给出，不计入总词数)； 2．必须包括表格中所有的相关信息，并适当发挥。 参考词汇：美德virtue Should We Help Strangers?

Recently our class had a discussion about whether we should help strangers.Different students have different opinions. Some think we should try to help strangers.Helping others is a virtue, and helping others is helping ourselves.We may come across some trouble and need others' help some day.If everyone isn't willing to help us just because we are strangers to them, it's hard to imagine what our world will be like. However, some are afraid that helping others can sometimes bring us trouble.Sometimes we are just misunderstood and even have to pay the cost of kindness. In my opinion, we should try our best to help others, but we should also protect ourselves from getting into trouble.If everyone tries a little kindness, our world will be full of love. $
