阅读：New Guinean Flatworms这种虫子在欧洲不断扩散。需要寻找方法控制它蔓延的趋势。提到如下三种方式：
1. Biological control：引入predator，或者依赖当地的鸟类
2. Chemical control：使用pesticide。
3. Soil fertilization：翻耕土壤，提升肥力，使用肥料，提升土壤温度，杀死虫卵。
听力：三种控制方式都不成功
1. 引入predator会导致被引入的种群无法控制。当地鸟类都不吃这种虫子，味道酸难吃。
2. 使用pesticide杀死该虫子，目前没有十分有效的针对该虫子的杀虫剂。唯一的一种Lindane 稍微有效果，但不明显。
3. 翻耕土壤的方法不容易达到杀死虫卵所需温度，效果不好。
范文
The reading lists three way to prevent the spread of New Guinean Flatworms and the lecturer gives his prospective to prove that all those methods don’t work.
The first methods is to introduce the predator or other local birds to kill them. However, the lecturer points out that the imported species will eventually become another kind of biological invasion and the local birds actually don’t like to eat them due to the bad taste. Thus, the biological control seems unlikely to be effective.
Another way is to use pesticide to control the population of flatworms. As to this way, the professor regards that we don’t have the certain and effective pesticide to kill the New Guinean Flatworms. The only one we can use is Lindane, but actually it is not sufficient. In other words, chemical control is not suitable.
The third method is to add some powerful fertilization so that the heat will kill the eggs. The professor claims that the temperature are not high enough to kill the small pests and pest eggs. Rather, they may be the great threat of the local crops, which means that we cannot use this way to stop the spread.

Rather than help children with their schoolwork, parents should encourage their children do their work independently.
范文
Completing schoolwork on time is actually not easy tasks for most students, especially for those underachievers. In this situation, some parents can’t bear to see their kids work late till midnight but with little progress, so they help their children to do the homework. Nevertheless, the parents should realize the importance and meaning of assignments and children will be the great beneficiaries if they do the work by themselves.
The first benefit is to cultivate their learning ability. With the help of parents or teachers, students hardly develop their own way to think, to analysis and even to explore the unknown world. Most of them will be frustrated when they find that they cannot be well-informed and learn something new at work. On the contrary, students who are asked to do homework alone have already been equipped with certain ability about how to deal with the difficulties in school time, and because of this, they prepare well for the future challenge, regardless of the unknown and the unexpected. Compared with the future benefit, the current difficulties in learning alone, clearly, doesn’t matter.
Aside from necessary capabilities, mental independence is another factor to ensure their bright future. The kids who get used to working alone surely rely more on themselves in the future. My cousin Lily is such a girl whose father always ask her to solve the school work by herself. She are never afraid of the unknown challenges and always strong enough to be the pillar of her friends when they study abroad and live in a foreign city. I don’t think there is anything wrong with an individual act weakly among his or her close friends and lover, but when they truly need to rely on themselves, they are supposed to be stronger.
When I talk with some parents about this issue, they think that their children are too young to avoid many mistakes in their schoolwork, which may finally destroy their self-confidence. How much do they know about their “baby”? They just look down upon them and seldom trust that the children can make up their mistakes and more importantly, learn how to be responsible for their schoolwork. If they have never made mistake and experienced the process of solving problem, that will surely lead to the consequence of “no confidence”.
In conclusion, in the way of educating students, it is significant to encourage them to complete task and learn by themselves. Only through that way can students be really aware of the knowledge and methodology learned in school and can they be well-developed into individuals.
