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

銆銆It is only natural that we do things that we enjoy doing. However锛 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.

銆銆In their personal lives锛 people sometimes have to accomplish tasks that they dislike doing.

But we do them because we need to maintain an orderly family life.

銆銆Models of Egg Development

銆銆Several different theories have been put forward to explain how the hard-shelled eggs of land-dwelling reptiles 锛坋.g. lizards锛 evolved from the soft eggs that amphibians 锛坋.g. frogs and toads锛 lay in water. The Romer model of egg development is named after the late Alfred Romer锛 a paleontologist who also became director of the Harvard University Museum of Comparative Zoology. His specialty was early reptiles because锛 he felt锛 they were the key to understanding the great reptile diversification seen in the Late Paleozoic and Mesozoic Eras 锛坅round 230 million years ago锛. Romer锛噑 hypothesis was that some aquatic amphibians that is锛 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锛 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锛 though锛 the transition was made锛 but these early reptiles remained aquatic. The advantage for laying eggs on land was primarily to avoid the aquatic larval 锛坧re- adult锛 stage during which immature amphibians live exclusively in water with its inherent risk of predators and drying of ...

銆銆Task1

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

銆銆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锛 so the quality of the project could be better guaranteed锛 an early start also allows us to follow a systematic plan and enjoy an unhurried schedule. Actually锛 I used to procrastinate a lot锛 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锛 and the result was a nightmare.
