21日考试（增加听力和细节）！回报CD

yetemwok

看了自己写的咚咚，有点过于粗略。加点细节进去，回报CD吧。even though i can understand them, but for XDJM who didn't sit the exam, they are too brief.

想起点听力了

1。 步行街的设计： 在20世纪早期，市中心居民减少，所以大家都想办法把人找回来，办法是建设步行街PEDESTRIAN SHOPPING MALL。 这个绝招是EUROPEAN发明的，美国在1950晚期搞的很好。老太太主要说设计步行街需要注意的问题：一个是LOCATION，必须靠近1。CONVENTION CENTER，传统居民集中区域，2。靠近公共交通设施PUBLIC TRANFFIC，同时需要解决PARKING 问题，因为有人要开车。 第二是DESIGN要合理和吸引人。不需要太多的雕塑等等装饰，但是步行街内部的交通设计要合理，让SHOPPERS觉得舒服才行。老太太给了一个从失败到成功的例子。THE PEDESTRIAN SHOPPING MALL， LOUISVILLE。由于地点不好，所以生意开始非常不好，但是后来交了狗屎运，政府在旁边修了好多好咚咚，所以生意就好。

2。 最后一题： 讲的是彗星，流星，陨石和其他太阳系行星的关系，主要讲了流星和陨石。开始老奶奶说大部分COMET AND METERITES都在MARS AND JUPITER之间 ORBITING THE SUN，而且他们的成分也和MARS，SMALL BUT OF ROCK，和JUPITIER， GIANT GASEOUS PLANET。这些都很明白。后来我迷糊了，呵呵。讲了ASTROIDS， METEROIDS，METERITES的关系。这个还好。在后面是和学生的交流教学了。奶奶说其实95%的陨石都是STONY， 哦，陨石分三中；STONY， IRON-STONY AND IRONY。（不知道这些鬼词语怎么翻译），但是我们在地面能找到的大多数是IRONY的，原因有个MM说是因为IRONY的好找，因为成分是IRON AND NICKLE，所以可以用METAL DETECTOR去寻找，但是， STONY 的陨星就不好找，因为他们经常和别的ROCK混在一起了。 这道题目听的时候好像明白了，但是做题目很差，因为当时脑袋罢工了，整个BLANK了。

其他题目，现在想不起了，如果有NN开个头，我就能整个想起来了。和唱歌一样，不知道怎么起调子。

speaking questions:

3. Reading part: university plan to build a new sport complex becaus currently students have to wait for a long time to get physical facitities and the culprit for this is the shortage of rooms available at present.  Therefore, the university plan to build a new sport complex that sits north to the current one, in hope of alleviating the cramped conditions in the gym.

Listening: MM doesn't like this plan. As she believes, the current problems are not caused by  lacking rooms, but by the poorly maintained exercise machines, as many of which are currently not working properly or simply not working. As she thinks, what the school needs to do is to repair the equipment, and building a new center is not a wise decision. Besides, the new complex is too far from the center of the campus. it takes 20 minutes to get there from the dorm. As a resul, maybe fewer students will take advantage out of this new sports center.

4: Reading: People work differently when working alone and with other in a group.

Listening: an experiment discussed to support the viewpoint in the reading. a group of people are to work on puzzles on computer. before entering the room, half of the people are told that they will work alone and be scored individually. at the same time, the rest half are told that they are to be averaged as per the integrated performance of their group. as the result, the people in group work better and faster. as scientists observed, they also seem to be more relaxed.

5. MM like most to take African culture about Ghana, but time of the class conflicts with that of her tutoring, both of whic are on Tuesday evening . GG propsed two options: 1. to change time of tutoring. mm says she works well the man, her tutor.  2. to take the class, the culture class of Ghana next semester. mm says her prof will probably go to ghana at end of this semester and maybe there will be no class available for next semester.

6. Protection coloration is defined as that some animals disguise themselves so as to make them visually unable to be seen by predators. There are two types: 1.cryptic coloration, in which animals can change the color of their skin, hiding them in the environment. one example given is lizard, details are what happening when it walks through grass or near tree trunck, its color can be changed within seconds. 2. disruptive coloration is to disrupt , or baffle predators. Example,  zebro has stripes on its body, which can puzzle its predators by mixed them into the surrounding environment.

Reading Parts:

1. how to know the coming of volcanoes; 1). by increased and intensified seismic activities; others, such as temperature in the proximitry of the volcano and stange behavior of animals  before eruption; usefulness of predicting volcanic eruption: saving many lives. one example is given in a place(i forget the name, hehe, saved 80,000 people by evacuating residents before eruption)

2. the important role of predators in maintain a ecosystem: 1. prevent one or two species too strong and eliminate the existence of others 2. an exmperiment by a stupid us guy, handpicking all the barnacles from rocks along seaside for six years 3. one example in Britain glassland: if grazing herds such as sheep are removed, few years later, only shrubs can survive in the area.

3. transportation development in US: 1. indisnpensibility of improved transportation sys in US after revolution; 2. benefits from regional and tanscontinental roads development, eg. the spread application of cast-iron plow invented by a farmer from New York state (north and west region of the state) and this brought more food and fruit for city dwellers in the east 3. center parts: the construction of canal Erie, 3 benefical factors: merchants in NY wanted the water-borne transportation means; NY govener supported the project; and terrain along the canal is very gentle. 4. benefits from canal Erie. It is a success because it soon could sustain itself just after two years from begining. Another problem was no naturally available water to maintain the water level in the canal so many reservoirs were built for this purpose.

综合写作：

PRIVATE/COMMERCIAL FOSSIL COLLECTORS NOT GOOD BECAUSE 1。 MAKE PUBLIC INTERESTS DEMINISHED BECAUSE THEY KEEP FOR THEMSELVES 2。 PUBLIC INSITITUTIONS NO MONEY TO COMETE AGAINST PRIVATE BUYERS SO THAT ACCESS TO STUDY DECREASE 3。 DAMAGES DURING PRIVATED EXCAVATION

LISTENING：

一个老太太说读的全是胡说，因为：

1。 私人收藏也让学校等等等参观，所以提高了公众对考古的兴趣

2。 化石是否值钱是科学家说了算，所以，在购买的时候科学家有优势

3。 虽然有损害，但是如果私人不找琢磨，化石可能永远都无法发现。

这个题目有点损，因为老太太的反驳不是很直接或者全面的反驳，他是绕了个弯来反击的，所以写起来有点罗嗦。

独立写作： 传统大家庭不再重要。 赞同或不？这个题目比较无聊，写了532个词，废话居多！

希望对大家有帮助，也等记性好的NNN来补充听力部分
