  1. Do you agree or disagree with the following statement? People should sometimes do things that they do not enjoy doing. Use specific reasons and examples to support your answer.

  It is only natural that we do things that we enjoy doing. However, doing things that we hate to do is a basic component of life. I agree that people occasionally have to do things that they dislike doing. There are a great number of things that we should do but hate to do. Moreover, by doing things we hate to do first, sometimes we learn to like them.

  In their personal lives, people sometimes have to accomplish tasks that they dislike doing. Who enjoys visiting a doctor, for example? We do this, however, because it is essential to taking care of our health. I do not know many people who enjoy doing household chores. But we do them because we need to maintain an orderly family life.

  In their professional live, people occasionally have to finish tasks that are not fun, but that are essential components of their jobs. Few people like to work with someone who no one else likes. But if the person is a representative of our business partner, we may have to work with the person. If we are teachers, we may sometimes have to disciplin...




  Models of Egg Development

  Several different theories have been put forward to explain how the hard-shelled eggs of land-dwelling reptiles (e.g. lizards) evolved from the soft eggs that amphibians (e.g. frogs and toads) lay in water. The Romer model of egg development is named after the late Alfred Romer, a paleontologist who also became director of the Harvard University Museum of Comparative Zoology. His specialty was early reptiles because, he felt, they were the key to understanding the great reptile diversification seen in the Late Paleozoic and Mesozoic Eras (around 230 million years ago). Romer's hypothesis was that some aquatic amphibians that is, amphibians living in water called anthracosaurs began to lay their eggs on land at about the time that they were evolving reptile-like skeletal features. Indeed, some of these early amphibians and earliest reptiles are so similar in their skeletons that the exact transition point from one to the other is still difficult to determine. Eventually, though, the transition was made, but these early reptiles remained aquatic. The advantage for laying eggs on land was primarily to avoid the aquatic larval (pre- adult) stage during which immature amphibians live exclusively in water with its inherent risk of predators and drying of ...





  1. Do you prefer to prepare something a lot of time before deadline or wait until the last minute before deadline? Please give specific reasons and details to support your idea.

  I would try to start a project as early as possible. Because an early-start leaves us sufficient time and energy to improve and revise, so the quality of the project could be better guaranteed; an early start also allows us to follow a systematic plan and enjoy an unhurried schedule. Actually, I used to procrastinate a lot, and a lousy time management only leads to bad consequence. I remember I was once invited to attend a high-level school presentation contest. So many things were distracting me at the time and I waited until the night before the deadline to start writing my speech, and the result was a nightmare. My mind went blank automatically when I was on the stage, which was totally embarrassing.

  Sometimes we are assigned to work in a group on a project. Do you agree or disagree with the following statement? The group will be helped more by person who will be willing to do what other group members want than by person who often strongly insists that things should be done in a way that is different from what the group wants to do.

But at some universities, experts are hired to make this decisions, students almost never involved. Which approach do you prefer and why.




  Title:Sociality in Animals

  Social insects represent the high point of invertebrate evolution. Some specieslive in communities of millions, coordinating their building and foraging, their reproduction, and their offspring care. Yet sociality is found in only a few species of insects, and is rare among vertebrates as well: wildebeest (large antelope)and lions are the exception rather than the rule. Nearly all fish, amphibians, reptiles, birds, and mammals are solitary, except when courting and mating. Birds and mammals usually rear their young, but year-round family groups are almost unknown, though they are intensely studied where they do exist. The same is true for insects.

  We know, or think we know, that social groups are good. Wolves are better predators when they hunt in packs, and pigeons escape from falcons far more often when feeding in flocks. Group building projects—the dams beavers build to block a body of water that provides them with relative safety from predators and the lodges they build for shelter, for instance—can provide a high level of protection and comfort. Why, then, are social species so very rare? In fact, living socially presents inevitable problems that transcend habitat needs so that only when these costs are offset b...
