1. habitat destruction生存环境的破坏，大多由于人的占用导致。
2. 附近捕食者(比如秃鹰和乌鸦)对幼鸟和蛋的攻击. Eggs and juvenile are vulnerable to the predators, which, however, cannot be killed because they are also important to ecosystem.
3. 保护濒危物种通常科学家会raise them in captivity 然后release into the wild, 但是Hermit Ibis是迁徙类动物，它们是从父母那里学习how and where to migrate， 如果人工饲养然后放回大自然，它们无法生存。
1. hermit ibis可以在很多地方筑巢，人工搭建的栖息地，比如建筑物的外墙。这个不是问题。
2. 虽然eggs and juvenile are vulnerable，但是它们的天敌都比较胆小，只要在eggs and juvenile成年之前人类通过吹哨子赶走天敌，Hermit Ibis成年后生活就没有问题了。
3. 人类也可以教给年幼的hermit ibis如何迁徙，比如pilot带着年幼的hermit ibis随着它们迁徙的路线飞行，它们也可以学会如何迁徙，放回大自然后它们的生存就不会有任何问题。
Contrary to the belief in the passage that it is difficult to protect hermit ibis, the professor asserts a diverse perception.
To begin with, the professor argues that hermit ibis actually can build nest everywhere. For example, the wall of buildings is perfectly suitable for them to build nest. Habitat destruction won’t be a problem to prevent scientists from protecting hermit ibis. This directly challenges the first idea in the reading that like many other endangered species, it is difficult to protect hermit ibis because of the habitat destruction.
Then, the author of the passage points out eggs and juveniles are vulnerable to the predators, which, however, are not supposed be killed because they are also important to ecosystem. However, their predators actually are coward species. People can easily blow whistles to scare away the predators during the period in which they are vulnerable. When they grow up to adults, there will be nothing to be worried about anymore. Again, this contradicts what the reading passage says about the same issue.
Finally, the professor points out that human can also teach young hermit ibis how to migrate. For example, pilots can flight along hermit ibis’ migratory route thus young hermit ibis that is raised in captivity will follow this route and become capable of migrating just like their peers living in the wild. Yet, the reading is of the opposite view that hermit ibis raised in captivity by scientists don’t have the chance to learn how and where to migrate from their parents.
Do you agree or disagree: it’s better to relax through watching a film and reading a book than doing physical exercises?
Everyone in the society is seeking for a way to release his or her pressure derived from continuous study or work, but what is the key factor of getting completely relaxed? There are two choices – the first one is to sit themselves to a comfortable couch, watching movies and reading books while the other is to go out and do physical exercises. Although someone tends to choose the first approach, I definitely agree that doing physical exercise is a better choice for those who want to relax themselves.
The first and foremost advantage of doing physical exercise is that it helps people stretch themselves and get recovered from anchylosis. People often feel stressed out because they sit still working or studying for 6 or more hours every day. Despite the difficulties caused by some sophisticated problems they need to deal with, sitting still for long is also one of the reasons that cause people’s intense pressure that is harmful to their health. In this case, doing exercise is a superb way to help them get relaxed. Actually, doing some sports that involve the whole body’s movement is the best, such as playing basketball, badminton. Jogging is also a good choice. On the contrary, watching a movie or reading a book still requires people to sit, which might worsen the situation instead.
To better relax ourselves, we must free ourselves from psychology stress. Doing exercise has two benefits in helping us achieve this goal. On the one hand, doing physical exercise facilitates the exudation of dopamine, which is a natural chemical our body secretes that makes us feel happy and relaxed. On the other hand, doing physical exercise generally brings us into contact with outside world. For example, when we jog in a park, the beautiful scenery there often refreshes our mind and takes us to a stress-free world. Besides, when we do some team sports, we communicate with our partners, sharing feelings and worries with them. They not only will cheer us up by saying some nice words but also may provide some suggestions for solving the problems we have. Clearly, we will feel much better after playing sports with them.
While some one may claim that we cannot ignore the importance of watching movies and reading books to relaxing ourselves since watching movies or reading books offer us greater chances to get away from the reality. Anyway, I admit that we can sometimes laugh by watching a comedy or enjoy the graceful description about pastoral country life thereby having an immersed sense. However, watching movies or reading books also requires us to stare at the screen or the book for long time, how can we have a good relaxation we still need to overfatigue our eyes? So, watching movies or reading books can be taken as good pastime when we want to spend weekends or holidays alone. And we should do physical exercise if we want to relax ourselves.
All in all, doing physical exercise is a superb way if we want to relax ourselves. It provides us with great opportunity to stretch ourselves and feel happy.
