5.B【解析】本题考查平抛运动。小圆环水平抛出后做平抛运动，其在空中运动的时间与下落高度有关，且t=2h,故小圆环落到a上表面的时间小于小圆环落到b上表面的时间，小圆环落到a上表面的时间等于小圆环落到c上表面的时间，A项错误、B项正确；平抛运动的初速度大小v=,故小圆环套住a的平抛运动的初速度大于套住b的平抛运动的初速度，同理小圆环套住a的平抛运动的初速度大于套住d的平抛运动的初速度，C、D项错误。

Does school start too early? Judging from the teenagers who yawn in class, it does. And those students aren’t just lazy. Scientific studies have shown that school does start too early for young students.

According to a series of studies done across the U.S., the later classes begin, the more academic performance improves. Boys and girls naturally stay up later and sleep in later. The trend begins around age 13 or 14 and peaks between 17 and 19.The teens also need more sleep in general, so forcing them to be up early for school cuts into their sleep time as well as their sleep rhythm, making them less ready to learn during those first-period classes.

Practice is proving the science. Hundreds of school districts in the U.S. have experimented with later start times and the academic performance of students has improved as a result. A study of 9,000 high school students in three states showed that grades in science, math, English and social studies all rose when school began at 8:35 or later. What’s more, attendance（出勤）goes up and student depression goes down.

The later school starts, the better the result, too. According to a study, delaying the opening bell from 7:30 a.m. to 8:30 a.m. paid off more than delaying only until 8:00 a.m. Students who get at least eight hours of sleep, and preferably nine, perform better than those who do not, so a greater delay raises the chances of achieving those numbers.

So, it turns out morning class is just too early for students to learn chemistry equations（方程式）or study an ancient poem. If you cannot change the school schedule, adjusting your own timetable to ensure eight hours’ sleep can also help you perform better at school.

1.If the first period class begins too early, which problems might appear among students?

a. Being in low spirits.

b. Feeling sleepy.

c. Missing lessons frequently.

d. Performing poorly in English.

e. Becoming lazy.

A. a, b, c B. b, c, d C. c, d, e D. a, b, d

2.The writer proves “School starts too early” by ______.

A. doing survey

B. doing experiments

C. comparing statistics

D. observing students’ behaviour

3.According to the article, students can obtain relatively enough sleep by ______.

A. changing the sleep rhythm

B. changing the opening bell

C. adjusting their own schedule

D. sleeping as late as possible

4.It is implied in the passage that in the morning ______.

A. there should be no classes

B. students’ sleep should be guaranteed

C. there should be Chinese lessons

D. there should be no science lessons

试题答案

1.A

2.B

3.C

4.D

【解析】

试题分析:本文主要说明学校不应该开始太早，否则学生极易打瞌睡，学习成绩也提不高。

1. 细节理解题。从文中第一段those students aren’t just lazy.这些学生不只是懒惰，可知e正确，从文中第二段Boys and girls naturally stay up later and sleep in later. 男孩和女孩自然熬夜到很晚，睡觉也晚。由此可知b正确，从文中第三段做的实验可以看出，What’s more, attendance（出勤）goes up and student depression goes down. 更重要的是，出勤率上升，学生抑郁情绪减少了。故a正确；从文中第二段so forcing them to be up early for school cuts into their sleep time as well as their sleep rhythm, making them less ready to learn during those first-period classes. 所以迫使他们早起上学削减他们的睡眠时间以及他们的睡眠节律,使他们不太愿意在这第一节课学习。因此他们也会频繁地错过很多课。故c正确。故选A。

2. is proving the science. Hundreds of school districts in the U.S. have experimented with later start times and the academic performance of students has improved as a result. 实践证明科学。在美国数以百计的学校已经尝试晚点开始上学,结果，学生的学习成绩有所提高。因此可知，作者为了证明“学校开学太早”通过做实验等等办法，故选B。

3. you cannot change the school schedule, adjusting your own timetable to ensure eight hours’ sleep can also help you perform better at school. 如果你不能改变学校的时间表，调整自己的作息时间，保证八小时睡眠也可以帮助你在学校表现得更好。
4.细节分析题。从文章最后一段it turns out morning class is just too early for students to learn chemistry equations（方程式）or study an ancient poem.结果证明早上的课对学生们来说学习方程式或者一首古诗仅仅太早了，故可推知早上不应该有语文课或者数学这类理科性质的课，但是并没说早上不该有课，故选D。
