(时间:90分钟 满分:120分)
第一部分 阅读理解(共两节,满分40分) 第一节(共12小题;每小题2.5分,满分30分)
阅读下面短文,从每题所给的A、B、C、D四个选项中,选出最佳选项。
A
Behaviours such as smoking,poor eating habits,and physical inactivity(静止) greatly increase a child’s risk of getting cancer in adulthood.For many kids,these and other harmful habits are already well established by the age of 13.In America,almost two-thirds of cancers could be prevented if these behaviours were never started.The earlier children learn how to prevent illness,the healthier they will be.The ways to make healthy decisions are learned during childhood.It’s far more important to practice a good habit from the beginning than it is to quit an unhealthy one!
School health isn’t just about what’s taught in the classroom.It’s about creating policies and programs that increase healthful living.It’s about forcing healthy habits every day and every year when kids are in school.Children’s health and education are harmed by risky behaviours such as using tobacco and drugs,failure to use seat belts,carrying weapons,lack of physical activity,and poor diet.A good school health program includes:
Health education in the classroom.
Healthy choices in the school cafeteria(自助餐厅) and vending(自动销售) machines.
Physical education that promotes regular exercise,heart fitness,and sun safety.
Family and community involvement. 1What is the passage mainly about? A.School health. B.Less acting. C.Eating habit.
D.Growing. 答案:A
解析:主旨大意题。从整篇文章来看,本文主要介绍了学校的健康教育问题。 2What does the underlined word “quit” mean in the first paragraph? A.convince C.get rid of 答案:C
解析:词义猜测题。由词后的“anunhealthyone”可以推断出对于不健康的习惯应该是“摆脱”。
3According to the passage,which is NOT right?
A.School health is not just about what’s taught in the classroom. B.Weapons shouldn’t be taken into school. C.Students don’t need to use seat belts.
D.Healthy habits should be paid attention to every day. 答案:C 解

4In a good school health program, should be included. A.no health education given in the classroom B.less exercise C.parents’ care D.more drugs 答案:C
解析:推理判断题。从第二段的“Agoodschoolhealthprogramincludes...”及最后“Familyandcommunityinvolvement.”看出父母的参与也是其中一部分,involvement“插手;参与”。
B
Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree,new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders.Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs.
A second study,looking at nearly 1,000 grown-ups in New Zealand,found lower education levels among 26-year-olds who had watched lots of TV during childhood.But the results don’t prove that TV is the cause and don’t rule out that already poorly motivated youngsters(年轻人) may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15.Those with college degrees had watched an average of less than two hours of TV per weeknight
during childhood,compared with an average of more than 2had no education beyond high school.
hours for those who
In the California study,children with TVs in their rooms but no computer at home scored the lowest,while those with no bedroom TV but who had home computers scored the highest.
While this study does not prove that bedroom TV sets caused the lower scores,it adds to accumulating findings that children shouldn’t have TVs in their bedrooms. 5According to the California study,the low-scoring group might . A.have watched a lot of TV B.not be interested in math C.be unable to go to college
D.have had computers in their bedrooms 答案:A
解析:推理判断题。第二段中描述的对加利福尼亚北部接近400名三年级学生的研究发现,
卧室里有电视的学生要比卧室里没有电视的学生考试分数低8分左右。据此推断考试分数低的原因可能是看电视太多。故选A项。
6What is the researchers’ understanding of the New Zealand study results? A.Poorly motivated 26-year-olds watch more TV. B.Habits of TV-watching reduce learning interest.
C.TV-watching leads to lower education levels of the 15-year-olds. D.The connection between TV and education levels is difficult to explain. 答案:D
解析:细节理解题。根据第三段最后一句话可知,对大约1000名新西兰成年人的研究结论是:受教育水平低不一定是因为看电视过多,但也不能排除。据此推断观看电视和受教育的水平之间的联系很难解释。故选D项。
7What can we learn from the last two paragraphs? A.More time should be spent on computers. B.Children should be forbidden from watching TV. C.TV sets shouldn’t be allowed in children’s bedrooms. D.Further studies on high-achieving students should be done. 答案:C
解析:细节理解题。倒数第二段提到卧室里有电视机没有电脑的孩子考试得分最低,而卧室里有电脑没有电视机的孩子得分最高;最后一段的研究结论是:这项研究虽然不能证明是卧室内的电视导致了孩子考试分数低,但为孩子卧室内不应该放有电视机增加了证据。据此判断不能在孩子卧室放有电视机。故选C项。
8What would be the best title for this text? A.Computers or Television
B.Effects of Television on Children C.Studies on TV and College Education D.Television and Children’s Learning Habits 答案:B
解析:主旨大意题。第一段指出,几项有关电视对孩子的影响的研究结果表明:看电视过多会对孩子的学习能力造成危害,甚至会减少孩子升入大学的机会。随后几段分别对几项具体调
