口说:
Task1
Describe a special event or occasion which you've experienced with your family or friends. Explain why it was memorable to you. Include reasons and examples to support your response. Task2
Some people prefer to get advice from older people like their parents or grandparents. Others prefer to get advice from their peers of the same or similar age. What way do you prefer and why? Use specific reasons and examples to support your opinion
Task3
【学校通知】：大学 computer lab的 new printing policy：每个学生每次到 computer lab最多只能 free打 10 pages。after printing more than 10 pages，more than 10 pages 的部分per page 要 charge 5 Cents。好处 1、督促学生节约用纸。好处 2、学校可 with the money collected 再 buy更多新 printers供学生使用。
【学生态度】：女生赞成此计画 the idea is OK with me。理由 1、以前 free 打的时候，she always see a lot of students print tons of material, sometimes only a title or an author is printed on a piece of paper, and the rest of the paper is left blank。It's a huge waste of material。如收费，在 while printing时，学生就会consider before printing，节约用纸 use paper more efficiently and selectively，students jot down the title or the author and print only necessary information rather than printing whole
page。理由2、there are only a few printers, students have to wait to print. The money will be used to buy new printers 给同学们用，就可效减少在 busy hours 时的 waiting time，不会发生以前人多时打印机不够用的情况。
Task4
【名词解释】：place marketing（地区行销）是：an area identify the features of a place 来做广告，可以和其他的地方区别开来，吸引游客 attract potential visitors。提高经济。
【教授举例】：教授举了一个例子。a town near oceanwants to improve its economy，这个 town 不仅有 a very beautiful beach，还有其他地方没有东西——bicycle paths connected to the beach 可以 ride bicycle往来于 downtown 和 beach 之间，不像其他地方只能 drive。So the government decided to emphasis this major feature to attract people who are fond of physical activities。They advertised this feature on TV and magazine 宣传在这个 town 不仅可以欣赏美丽的 beach，还能参加各种 physical activities，比如 play
volleyball and jogging on the beach，骑自行车等。It turned out to be successful，吸引了很多active 的 young people came to the town 玩。town 里的新 business，比如 hotel、restaurant、旅游品店、礼品店等都蓬勃发展起来了。最后，这个 town 的经济也发展了 promote the economy。
Task5
【学生困难】：一个女的暑假要去 in another state 打工 summer job，帮她导师做事。她很喜欢现在的公寓，她想 fall 打完工回来接着住现在的公寓 apartment。不知道自己的宿舍怎么处理。
【解决方案】：男生给她两个建议：建议 1、在暑假期间，把apartment 转租 sublet the apartment to 一个朋友，这样做既可让别人掏房租，这样还有钱赚，又可搬回去。she worries the visitor may mess up her room。建议 2、干脆 pays both rents。等她假期回来后继续居住。但女生说她打算用暑假打工 get money to purchase a new computer。如果两边都付了房租，没钱买电脑了，下个 semester 有钱买电脑了。
Task 6
1.【讲课要点】：Animal Communication：When animals are in dangers，they alarm other individuals with two types of alarming signals： 第一种、alarm call：give a call。例如：A robin cries to alarm other robins that a predator is coming。Other robins will fly off。 第二种、chemical alarm signals。例如：When a minnow’s skin is cut, its skin can release some chemical substance to let other minnows know that the danger is nearby，then others minnows in the same pond would hide
themselves。题：讲动物如何发信号通知同伴。
整合写作：
大脑 size 在 200000 年年前，逐渐变小的原因
Reading:
1.天气变化，变暖有利身体小，所以大脑也小了
2.农业发展：饮食不再以肉为主，而以谷物为主。缺少蛋白质和维生素的摄取，
所以大脑变小
3.肌肉变小：现在人肌肉少了，所以控制肌肉的大脑也变小了
Listening
1. 温度有波动，大脑却一直减小
2. 全球人类大脑都在缩小，有些地方（非洲）还没有出现农业，那里的人脑容量也变小了
3. 人类肌肉变小只是很小的一部分，但是大脑却减少了 10%
独立写作:
A/D: It is better to relax by a movie or reading a book than doing physical exercise.
