綜合
閱讀：一種在北美的野馬mustang需要限制它們在牧場上面的數(shù)量
1. 因?yàn)橐榜R會吃掉很多的草overgraze，破壞土壤和整個牧場的動植物生態(tài)圈
2. 因?yàn)檫€有其他的farm animal，cattle 和 sheep等，野馬太多會破壞整個牧場的carrying capacity
3. 野馬喝水會破壞水質(zhì)并且阻礙juvenile fish的生長
聽力：反對
1. 野馬只是吃掉表層的草，不會破壞root，還能繼續(xù)生長，另外野馬的糞便糞便可以當(dāng)做fertilizer，反而對草是有益的
2. 野馬的存在可以保護(hù)sheep的數(shù)量，因?yàn)椴东C會同時捕這些動物，野馬數(shù)量減少的話，就會捕更多羊
3. 野馬的存在并不一定是對young fish有害。舉了beaver的例子，之前這里有海貍，它們筑起了dams，減緩了water flow，更適合小魚生長。后來海貍消失后，小魚的數(shù)量反而下降。
Sample Answer:
The reading passage lists three reason why the population of mustangs should be limited in the pasture, while the lecturer contradicts all those theories respectively.
Firstly, the mustangs won’t destroy the ecosystem of the whole pasture because those mustangs only eat the surface grass and won’t break the root, which ensures the further growth. Besides, the faeces become fertilizers, so they are beneficial to the grass. Therefore, we don’t need about the negative effects on the ecosystem if the mustangs are overgrazed.
Second, according to the passage, mustang will also break the carrying capacity of the whole pasture because there are other farm animals like cattle and sheep. However, the existence of mustang will actually protect those farm animals. If their population are limited, the predictors will kill more sheep.
As to the harmful effect of juvenile fish, the professor also claims that mustangs won’t do harm to young fish. Another example that juvenile fish build up dams to reduce the water flow, which suits the young fish, whereas their population decrease after beavers disappeared. Thus, the claims in the reading that mustang will pollute the water and stop the growing of juvenile fish. (194 words)
獨(dú)立
Students aged 13-18 are taught different subjects by different teachers while younger students are taught by only one teacher all day long. Some people suggest it would benefit young students to be taught by different teachers. Do you agree with this view? Why or why not?
Sample Answer:
There is quite a strange phenomenon that students who are under teenage are treated differently just due to their “particularity”. It is true that the teachers of younger students are given special mission but, contrary to the opinion from most people, I insists that younger students can be better educated if they have different teachers.
The first benefit is that they can experienced various teaching method from different teachers. Under the schooling of single teaching method, students’ mind will be limited deeply, which decrease their creativity and cut off the possibility to further development. Worse still, if the only teacher go something wrong, there will be no chance to correct the mistakes due to absence of comparison. On the contrary, if several teachers show different personalities and characters to students, they will know comprehensively about the world, the people and themselves. Time and time again, they will be arguably equipped with the skills to tell right apart from wrong. Since our civilization allows diversification, the growth that younger people are expected with should also be diversified.
Given the professional knowledge in different fields, teachers should also be asked to do what they truly major in. We always expect that a man should be generalists rather than specialists, but the fact is the formers usually do the things worse and, in other words, less professionally than those specialists do to some degree. Similarly, the teachers who are skilled in logical thinking like math and science may be poor at art and music. With the help of those teachers, students surely receive better education and learn deeply in each subject, despite their interest and preference. Clearly, professional events suit those professionals.
Some may claim that as a result of their young age, younger students are more likely to have close relationship with the one who they think are reliable. However, is that good news? Kids who are always regarded over-dependent to someone are under overprotection actually. Relying on certain and being afraid of learning new things from other “strangers” largely reduce their process to view the world, which stop them from being mental mature and being independent. After all, regardless of their young age, students are not toddlers anymore.
All in all, given their comprehensive development in knowledge and personality, students should be surround by many teachers who have their own traits. (390 words)
