If you are a high school senior graduating and looking to enter college in 2006, you will take the new exam.

The biggest change to the SAT (美国学术能力倾向测验) will be the introduction of a new writing section. The writing section will consist of two parts: an essay and a multiple-choice section. Students will be given 25 minutes to respond to a prompt (提示) and construct a well-organized essay that effectively deals with the task. The essay question may require students to complete a statement, to react to a quote, or to agree or disagree with a point of view. In any case, a good essay will support the chosen position with specific reasons and examples from literature, history, art, science, current affairs, or even a student's own experiences.

Essays will be scored based on the procedures for the current SAT II: Writing Test. Essays will be graded by two independent readers On a scale of 1～6, and their two scores will be combined to form an essay subscore that ranges from 2 to 12. Should the readers' scores vary by more than 2 points, a third reader will score the essay; The readers will be high school teachers and college professors who teach composition. To ensure that essays will be scored in a timely manner, they will be scanned and made available to readers on the Internet for grading purpose.

The writing section will also include multiple-choice grammar and usage questions. Some of these questions will call upon students to improve given sentences and paragraphs. Others will present students with sentences and require them to identify mistakes in diction (措辞), grammar, sentence construction, subject-verb agreement, proper word usage.

The highest possible score on the new writing section will be 800. Scores on the essay and multiple-choice section will be combined to produce a single score. A writing subscore will also be assigned. The highest possible scores on the Critical Reading and Math sections will remain 800 each, making 2,400 a perfect score on the new SAT.

By using skin―prick tests for detecting common allergies，the researches found that contrary to what many doctors had been taught for years，children wh0 had lived with a pet were not at greater risk.

Even more remarkable，children who had two or more dogs or cats had even great diction ,up to77 percent，in risk of allergies．Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats．Exposing young children to these bacteria helps“exercise”their immune systems early in life so that they're better able to resist allergic disease8 later．

There’s something Very important in that first year of life when the immune system developing that we can retrain it away from an allergic response，”said Dr．William Davis．

And while researchers are not encouraging parents to buy dogs 0r cats just to reduce a child’s allergy risk，they say if a family already has one or more animals，there’s no need to get rid of them．

Sometime early in the next century, human beings will move to Mars（火星）．They will live there for about a year，and then will be replaced with another group of pioneers．Building he base on Mars will advance our knowledge of the solar system and aid in our under standing of the earth．

We already know that Mars resembles the earth in many aspects：general size，presence of water，length of day． range of temperatures．These resemblances have caused many people to consider a centuries’ long project：to terraform Mars．Terraforming means altering a planet’s surface so that Earth’s life forms can survive there．This concept，previously found only in science diction is now being seriously considered by scientists．

Terraforming Mars is theoretically simple：add nitrogen and oxygen to the atmosphere；pump water to the surface；and add the earth’s plants and animals in the order in which they developed on earth．But it will take at least 300 years．

Some people think that such a project is too huge for humans to undertake，but there are very good reasons to make the attempt．The earth now contains some 6 billion people and no one has any idea of how many humans the earth can support．Our very existence and numbers are threatening many other species．We also have had some experience with terraforming our own planet：altering the landscape，the atmosphere and the climate．Currently terraforming earth has become a wiser activity as we try to control global warming，air and water pollution，and preserve some natural living places．

While the possibility of such a project is small，it is not impossible．Even if earthbound societies come and go in the next 300 years，the project can continue through the work of the Mars settlers without the need for constant backing from the earth．

The future existence of all the people in our world may very well depend upon our ability to terraform Mars．
