Task1
　　What can we do to solve air pollutionproblems?
　　Sample: The first thing thatI can think of to solve air pollution is to plant trees. Because now theindustry has been well developed so it is inevitable for the city to face largeamounts of emissions of waste gas. As we all know, trees can act like a machineto purify air by absorbing useless gas and releasing oxygen. Since we can’tstop industrial development, planting trees will help a lot to reduce thepollution problem. The second way is to encourage people to ride bikes or takewalk instead of driving cars. Because the cars can release tail gas which isalso a negative impact on the environment. If people have the awareness ofchanging their traffic modes, I’m sure it will work.
　　解析：此題為環(huán)保類話題，空氣污染是環(huán)境污染重最重要的一個話題。最常用思路為種樹，這邊需要學生素材積累：種樹能凈化空氣的原理。除此以外，騎自行車也是同學很熟悉的保護環(huán)境的方法，不難想到。
　　Task2
　　Which kind of roommate do you prefer: aroommate from a foreign country or a roommate from your own country?
　　Sample: I prefera roommate from a foreign country. First, the roommate with different cultural backgroundmay provide distinct perspectives of thinking of questions. Because we grew in disparateenvironment with different education pattern, she may give me some constructiveadvices that I haven’t thought of when I get into trouble. Second, the life canbe more interesting with the roommate from another area. We can share our ownlife experience and cook meals with local food for each other. Also, I willknow more about the culture of her hometown. With more knowledge about diversehistories and customs, I’m able to build a more comprehensive worldview as wellas respect others well.
