Task 1: what can the parents do to help their children succeed in school?
Task 2: Is it important for students to attend social activities, such as joining clubs?
Task3
学校有个cars rental program,一是可以让学生方便去town,二是可以让买不起车的学生出行方便。对话中女生同意， 两个原因：
1. The campus is far away from town, and the bus only runs in every two hours. If the students want to go to more places, they have to take a long time. So renting a car is more convenient for them.
2. Purchasing a car for herself will cost a lot of money, including the gas fee, repairs, parking fee and so on. So renting a car is better.
Task4
讲buffering。Weaker one takes infant to interact with stronger one to avoid provoking aggression。例子是monkeys in Japan,强者总是优先吃好的食物，弱者总是吃剩下的因为如果他去抢，强者会生气，为了避免这点，弱者会带着小baby去和强者一起吃食物，强者通常不会生气反而会食物共享。
Task5
女孩今晚要去姐姐家照顾孩子，姐姐和姐夫要去看concert，但她想起来今晚要写history paper。两种办法：
1. cancel去姐姐家，姐姐理解，但女孩觉得她们买的是新的票，不去看演唱会好像不太好。
2. 自己带着book和computer去姐姐家，但无法集中精力写。
Task6
讲座主题是architecture changes over time. 以前的建筑为了承重用很厚的墙，然而内部空间就压缩了，举例是tall tower。现在的建筑用钢筋来代替石头，就轻很多而且也承重，不用那么厚的墙，例子是tall office building。
