Question

【題目】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.

【4】 C

【解析】

本文經(jīng)過引用各種研究結(jié)果，主要是為了說明空氣不流通的教室對學(xué)生考試成績是否有影響，經(jīng)過各種研究，教室空氣質(zhì)量對學(xué)生學(xué)習(xí)效果和考試成績有影響是肯定的，但是影響并不是太大

【1】細節(jié)理解題。根據(jù)文章第一段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.可知本篇文章主要是講新鮮空氣對學(xué)生在考試中的影響，故選C。

【2】細節(jié)理解題。根據(jù)第二段A 2012 study showed that college students had more difficulty giving all their attention to their learning when indoor CO2levels were high.可知在二氧化碳濃度比較高時，大學(xué)生很難把注意力集中在學(xué)習(xí)上，目的在于說明室內(nèi)高濃度二氧化對大學(xué)生學(xué)習(xí)的危害，故選D。

【3】細節(jié)理解題。根據(jù)文章第二段Opening windows can help provide fresh air. Some buildings also use fans to bring in outdoor air.可知打開窗戶或使用風(fēng)扇可以降低把新鮮空氣帶到室內(nèi)，從而降低室內(nèi)二氧化碳的濃度，而并非降低空氣中二氧化碳的濃度，故A錯誤；根據(jù)文中Each time someone breathes, he or she breathes out CO2. When rooms are stuffy, the level of CO2in those rooms can build up.每個人都會呼出二氧化碳，當(dāng)房間不通氣的時候，二氧化的濃度就會升高，人越多二氧化濃度也會越高，故B正確；根據(jù)最后一段The study shows that air quality and test scores are really connected, but the influence is small.可知考試成績確實和空氣質(zhì)量有關(guān)但是影響卻很小，故C，D都不正確；故選B

【4】主旨大意題。本文經(jīng)過引用各種研究結(jié)果，主要是為了說明空氣不流通的教室對學(xué)生考試成績是否有影響，經(jīng)過各種研究，教室空氣質(zhì)量對學(xué)生學(xué)習(xí)效果和考試成績有影響是肯定的，但是影響并不是太大，故選C。

快速閱讀短文，了解本文大意，主要是說明教室空氣質(zhì)量對學(xué)生考試成績的影響，1,2,3小題都屬于細節(jié)理解題，例如第3小題，需要去文中找出每個選項在原文中的位置，對照原文，找到選項和原文的差異，判斷正誤。
