A套：
独立写作：young people are more likely to give time and energy to improve the world than young people were in the past.
综合写作：traffic cameras不好：1.不能像交警一下立即stop dangerous behaviour. 2. inconsistence. 3.设置在intersection会容易导致collision. lecture:1.真正问题不是immediate intervention而是change beahabiour, 而且交警拦人的时候别的车超速他根本都看不见。2. 交警人力花费大，覆盖面还不如cameras广。3.有了camera 司机更谨慎。
B套：
综合写作：reading是一个湿地面临危险，因为invasive plant入侵，干旱，mercury的level增加而环境危险。然后教授提了三点分别解决这个三个问题。听力说入侵是因为过度施肥土壤变的更适合入侵植物，所以少施肥就行。干旱是因为人工channel把水引走了，remove一些管道就行。汞污染是因为燃烧了含高汞的煤，所以改为烧低汞的煤就行。
独立写作：Do you agree or disagree with the following statement? Although science and technology will continue to improve, the most significant improvement for the quality of people’s lives have already taken place.
