2019秋高二年级英语北师大版必修5练习：Unit 15 过关检测(含答案)

第15单元过关检测(时间：90分钟满分：120分)Ⅰ.阅读理解(共12小题;每小题2.5分,满分30分)阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

AWhat do you hear?Sounds all around you!You can hear the sound of traffic,the wind in the trees,a dog barking,your own breathing and lots of other things.But what is the sound?Sound happens when something vibrates(振动)or shakes.We can make something vibrate by hitting it.Try this experiment.Put your ruler on your desk so that part of it sticks out(伸出)over the edge.Put your hand on the part of the ruler that is on the desk.Now pull the part that is sticking out over the edge down,and then let it go.The part you let go will vibrate.It will move up and down very quickly,and give out sound.The part of the ruler sticking out over the edge of the desk produced the sound.If you make that part longer,you will hear a lower sound.When you shorten it,you will hear a higher sound.Why does this happen?When you shorten the ruler,it will vibrate more quickly.When something vibrates more quickly it produces a higher sound.If you lengthen the ruler,it will vibrate more slowly.When something vibrates more slowly,it produces a lower sound.1.How does the sound happen?A.When something vibrates or shakes.B.When hitting at something.C.When a ruler is put at the edge of the desk.2.We can hear a sound if we make the part of the ruler sticking out over the edge of the desk longer.A.higherB.lowerD.nice根据第三段中“If you make that part longer,you will hear a lower sound.When you shorten it,you will hear a higher sound.”可知答案。

3.The underlined word “lengthen” in the passage means“”in Chinese.A.加长B.缩短D.摇动,故如果将尺子加长,则其振动越慢,发出的声音也就越低。

故此处lengthen意思是“加长”。

4.The best title of the passage is .A.An experimentB.A way of making soundC.Sounds are bad for usD.Sounds“声音”,故用D项作为标题具有很强的概括性。

B(2019全国课标Ⅱ)More students than ever before are taking a gap year(间隔年) before going to university.It used to be called the “year off”between school and university.The gap-year phenomenon originated(起源) with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year.This year,25,310 students who have accepted places in higher education institutions have put off their entry until next year,according to statistics on university entrance provided by the University and College Admissions Service(UCAS).That is a record 14.7% increase in the number of students taking a gap year.Tony Higgins from UCAS said that the statistics are good news for everyone in higher education.“Students who take a well-planned year out are more likely to be satisfied with,and complete,their chosen course.Students who take a gap year are often more mature and responsible,” he said.But not everyone is happy.Owain James,the president of the National Union of Students(NUS),argued that the increase is evidence of student hardship — young people are being forced into earning money before finishing their education.“New students are now aware that they are likely to leave university up to ￡15,000 in debt.It is not surprising that more and more students are taking a gap year to earn money to support their study for the degree.NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacation periods,” he said.5.What do we learn about the gap year from the text?A.It is flexible in length.B.It is a time for relaxation.C.It is increasingly popular.“More students than ever before are taking a gap year(间隔年) before going to university.”以及第三段第一句“That is a record 14.7% increase in the number of students taking a gap year.”可推知,间隔年比以前流行。

故选C项。

6.According to Tony Higgins,students taking a gap year .A.are better prepared for college studiesB.know a lot more about their future jobsC.are more likely to leave university in debt·希金斯所说的话“...Students who take a gap year are often more mature and responsible...”可推知,他认为选择间隔一年上大学的学生更成熟、更有责任心。

这样他们能更好地为大学学习做好准备。

7.How does Owain James feel about the gap-year phenomenon?A.He’s puzzled.B.He’s worried.C.He’s surprised.D.He’s annoyed.由第四段中的“hardship”“in debt”可知,欧文·詹姆斯对选择间隔一年上大学的现象并不感到高兴,即感到担忧。

故推知答案为B项。

8.What would most students do on their vacation according to NUS statistics?A.Attend additional courses.B.Make plans for the new term.C.Earn money for their education.·詹姆斯所说的话“...NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacation periods...”可推知,根据NUS的研究,绝大部分学生在假期打工为自己挣学费。
