Study hard. Get plenty of sleep. Eat a good breakfast. Each of these things can help students do their best on exams. Now scientists say another thing might also influence students’ test scores. Students in stuffier (通風(fēng)不暢的) classrooms did worse on tests than students in buildings with fresher air, new research (研究) found.

Opening windows can help provide fresh air. Some buildings also use fans to bring in outdoor air. Each time someone breathes, he or she breathes out CO2. When rooms are stuffy, the level of CO2 in those rooms can build up. A 2012 study showed that college students had more difficulty giving all their attention to their learning when indoor CO2 levels were high. And other research has found that primary school students in stuffier classrooms stayed homesick (想家的) more often. In a different study, researchers examined the air quality (質(zhì)量) in 100 fifth-grade classrooms. They found that in most classrooms, the air quality did not meet the standards (標(biāo)準(zhǔn)).

These same research groups now find that better air is connected with better test scores too. As part of the research, Richard Shaughnessy measured CO2 levels inside and out of 140 fifth-grade classrooms at 70 schools. The CO2 levels helped them know how much fresh air was running through each classroom. The quality of indoor air in each classroom was then compared to its students, scores on a Maths test. Overall, the average score for this test was 2,286 points. But kids in classrooms with the best air quality scored about 144 points higher than students breathing the stuffiest indoor air. The study shows that air quality and test scores are really connected, but the influence is small.

1.The findings of the new research mainly show the importance of _______.

A. hard work B. enough sleep

C. fresh air D. healthy eating

2.What did the author want to show by mentioning a 2012 study?

A. College students studied in stuffy classrooms.

B. High indoor CO2 levels harmed students1 health.

C. College students had difficulty in focusing in class.

D. High indoor CO2 levels harmed college students’ learning.

3.What can we learn from the passage?

A. Opening windows and using fans can reduce the level of CO2 in the air.

B. The level of CO2 will be higher when there are more people in a stuffier room.

C. Students studying in stuffier classrooms cannot get good test scores.

D. The air quality will seriously influence students’ scores.

4.What is the main idea of the passage?

A. Many classrooms lack fresh air.

B. Stuffy classrooms lead to problems.

C. Stuffy classrooms may lower test scores.

D. CO2 in classrooms leads to poor performance.

Dear John,

Thank you very much for your letter. I am glad that you enjoyed your holiday with me. We enjoyed having you and your sister here. We hope that you will both be able to come again next year. Perhaps you’ll be able to stay longer next time you come. A week is not really long enough, isn’t it? If your school has five weeks’ holiday next year, perhaps you’ll be able to stay with us for two or three weeks.

We have been long back at school for three weeks now. It feels like three months! I expect(期望) that you are both working very hard now that you are in Grade One. I shall have to work hard next year when I am in Grade One. Tom and Ann won’t be in Grade One until 2009.

Yours sincerely,

Michael
