Unit 1 Section Ⅲ Discovering Useful Structures-【精讲精练】2023-2024学年高中英语必修第一册人教版（课时作业）

Ⅰ.阅读理解

A

The first week of September was a week that I had been expecting all summer.I didn't want summer to end，but I was excited about going to high school for my first week.

When I got to school in the morning on the first day I realized how large the school was，and how many students went there.I ended up in the wrong classroom because of the size of the school.Luckily，a kind senior showed up and guided me to my homeroom before I was late.I was happy to see that in a class of unfamiliar (不熟悉的) faces，the only open seat was next to my good friend，Casey.My science teacher seemed like a good teacher.She was exciting and fun.

After finishing four periods without too much of a challenge，I didn't feel too bad about ninth grade.However，the fifth period changed everything.I didn't feel ready after all.My teacher's name is Mr.Valassidis but he told us to call him Mr.V.Mr.V told us that we would have to write 40 essays (文章) and read AP­level books such as The Odyssey this year.I love reading and writing，but come on,40 ESSAYS? AP­level books? Now I was afraid.

The courses in high school seem like they're going to get much harder，but they haven't yet.Even though my classes look hard，they look really exciting too.

The first week passed quickly.Although a lot of things were overwhelming (令人不知所措的)：the size of the campus，the crowds (人群) and the seniors，having a totally different experience than I had ever had before was really exciting.Now，I'm really happy about high school.I have lots of friends in my classes，I really like my teachers and I'm meeting new people.

B

Some educators told us that more years of school could help students get higher scores on intelligence tests.That was a finding of a study of teenage males in some countries.Now，another research shows that physical activity may help students do better in their classes.

The research comes as educators in some countries are reducing time for activities like physical education.They are using the time instead for academic (学术的) subjects like maths and reading.The studies included more than 55,000 children，aged 6 to 18.

Amika Singh：“According to the results of our study，we can conclude that being physically active is beneficial to academic performance.There are，first，physiological explanations，like more blood flow，and so more oxygen to the brain.Being physically active means there are more hormones (荷尔蒙) produced like endorphins (内啡肽)．And endorphins make your stress level lower and your mood improved，which means you also perform better.”

Also，students taking part in organised sports learn rules and how to follow them.This could improve their classroom behaviour and help them keep their mind on their work.

The study leaves some questions unanswered，however.Ms Stash says it is not possible to say

whether the amount or kind of activity affected the level of academic improvement.This is because of differences among the studies.

The researchers said they found only two high­quality studies.They needed more high­quality studies to confirm (证实) their findings.They also pointed out that “results for other parts of the world may be quite different”．

Still，the general finding was that physically active kids are more likely to do better in school.Ms Singh says schools should consider that finding before they cut physical education programs.Her paper on “Physical Activity and Performance at School” is published in the Archives of Pediatric and Adolescent Medicine.

[语篇解读]　说明文　一项研究发现：体育活动对学生的学习有益。作者呼吁我们要重视体育教育。

5．Which of the following is TRUE?

A．Being mentally active is good for academic subjects.

B．The more hormones you have，the more stressed you will get.

C．The researchers have found many high­quality studies to prove the research.

D．The educators in some countries think studies，not exercise，mean much to students.

解析：选D　推理判断题。根据第二段中的前两句可知，正是因为一些教育者正在减少体育教育的时间，而把更多的时间用在了专业性更强的数学或阅读学科方面，人们才进行了这项研究。

6．What does the underlined sentence in paragraph 6 probably mean?

A．Good marks result from high­quality study.

B．Findings are probably different in different areas.

C．Physical activity will spread all over the world.

D．Academic performance depends on the surroundings.

解析：选B　句意理解题。根据画线句前两句可知，研究人员认为他们只进行了两次高质量的研究，还需要更多的研究来证实这个理论。也许在其他地方的研究会得出不同的结果。

7．What's the passage mainly about?

A．A research on physical education has been done by the researchers.

B．There is a possibility that physical activity leads to higher grades.

C．The amount or kind of activity directly affects academic level.

D．The research shows that the children aged 6 to 18 don't do sports.

解析：选B　主旨大意题。根据第一段中的最后一句可知，一项研究表明体育活动可以
