Question

17．How do you usually go to school：walk，cycle，take a bus or drive？
Most people know that students who go to school by bus or car are more likely to put on weight than those who walk or cycle．But did you know that exercising less could also make you fall behind in your schoolwork？
Two Danish universities recently carried out a study of 19，527students between the ages of 5and 19．The students were asked how they traveled to school and were then given a test．It was found that the students who were driven to school，or took a bus，performed worse in the test because they had poorer concentration（集中注意力）than those who took a more active way．
"As a third-grade pupil，if you exercise and cycle to school，your ability（能力）to concentrate increases to the equivalent（同等）of someone half a year further in their studies，"said Niels Egelund，a member of the study．
Depending too much on cars is also a problem for adults．British people are much lazier these days．They are walking 80miles less every year than ten years ago，a new study found．
"This creates a huge illness problem and lowers their quality of life，but most people don't seem to know that it's a problem，"said Harry Rutter from the National Observatory，the UK．"Being short of physical activity is the fourth main cause of early deaths around the world and causes about the same level of ill health that smoking does．"
71．How many Danish universities recently carried out a study？Two/2．
72．Is depending too much on cars a problem for adults？Yes，it is．
73．Why did students drive to school often do worse in their schoolwork？Because they had poorer concentration than those who took a more active way．
74．How should students go to school in order to study better and be healthier according to the writer？They should cycle to school．．

Answer 1

分析 本文介紹了上學方式與學習成績的關系．文章說，據(jù)研究，駕車或乘公交車上學的學生的成績最差，因為他們的注意力很差．如果是一個三年級的學生經(jīng)常鍛煉和騎自行車上學，其注意力得到改善，這種能力和比他高半年的學生的水平相當．對于成人來說，太依賴汽車也會出現(xiàn)問題，比如疾病和生活質(zhì)量下降．

解答 71．Two/2．細節(jié)理解題．考查有幾所丹麥大學開展了一項研究．根據(jù)文章第三段中"Two Danish universities recently carried out a study of 19，527students between the ages of 5and 19"所說，兩所丹麥大學最近就19527名介于5-19歲的學生進行了研究．故回答Two/2．
72．Yes，it is．細節(jié)理解題．考查太依賴汽車是否會對成年人造成問題．根據(jù)第五段中"Depending too much on cars is also a problem for adults"所說，對于成年人來說，過于依賴汽車也會造成問題．故回答Yes，it is．
73．Because they had poorer concentration than those who took a more active way．
細節(jié)理解題．考查為什么開車上學的學生的成績最差．根據(jù)第三段中"It was found that the students who were driven to school，or took a bus，performed worse in the test because they had poorer concentration than those who took a more active way"所說，駕車或乘公交車去上學的學生考試成績最差，是因為他們的注意力比那些主動運用注意力的人的注意力要差．故回答B(yǎng)ecause they had poorer concentration than those who took a more active way．
74．They should cycle to school．
細節(jié)理解題．考查根據(jù)作者所說，為取得好成績，學生應該怎樣去上學．根據(jù)第四段中"As a third-grade pupil，if you exercise and cycle to school，your ability to concentrate increases to the equivalent of someone half a year further in their studies"所說，如果一個三年級的學生，平常經(jīng)常鍛煉，騎自行車上學，在學習中其注意力會比同等學生的注意力要好．
cycle to school騎自行車上學．故回答They should cycle to school．

點評 首先要掌握短文的意思，然后結(jié)合具體的題目再讀短文，從中找出相關信息，就可以確定正確答案．
