6.Hoverboards(电动滑板)were among the most popular Christmas gifts of 2015.They may have also been most dangerous gifts of 2015.
A truehoverboard looks like a skateboard without wheels.To"hover"means to flat in the air without moving much in any direction.The popularity of hoverboards began in the 1980s,with the"Back to the Future"movies.Characters in the second and third films used hoverboards as transportation.
This year's popular hoverboards,however,do not actually hover.They have wheels.And?as it turns out,they are not easy to use.
Adults and children around the world suffered hoverboard-related injuries over the weekend.Many posted pictures of the damage on social media.Twitter user David Douglas posted a photo of both him and a young girl with the broken arms they suffered on Christmas Day.And another user Erin Rafferty uploaded a video of her mother falling off a hoverboard,with the caption,"Who let mom on the hoverboard?"
Falling is not the only risk with some hoverboards.They are also a fire risk.At one store in Texas,an employee tried to fix a hoverboard a customer brought in.The hoverboard then caught fire.
Studies suggest that some hoverboard brands have defective batteries or plugs.
Many major airlines worldwide have banned hoverboards because of the fire risk.But some passengers did not hear the news.Australian actor Russell Crowesaid on Monday about his disappointment that Virgin Australia Airlines did not permit his children to take their hoverboards on the plane.
Major retailers (零售商)are also taking steps to improve the safety of the hoverboards they sell.Amazon in the United States now only sells hoverboards from brands that have submitted safety standrd documents.The UK's Amazon no longer sells hoverboards.It has also advised customers who bought unsafe brands of hoverboards to throw them away.

12.What's the problem with this year's hoverboards?C
A.They don't havewheels.
B.They catch fire in the sun.
C.They are difficult to handle.
D.They can't move in any direction.
13.We can infer from the passage that.C
A.the number of hoverboard-related injuries is declining.
B.hoverboards are still enjoying equal popularity as before.
C.hoverboards are still sold on Amazon in the United States.
D.passengers are forbidden to get on planes with hoverboards.
14.The underlined word"defective"in the sixth paragraph probably means.A
A.faulty  B.spare  C.dead  D.dry
15.We can probably read this passage in aA.
A.newspaper  B.textbook  C.science fiction  D.movie review.

分析 本文讲述的是当下流行的电动滑板所隐藏的危险性.

解答 CCAA
12.C 考查细节理解.根据"as it turns out,they are not easy to use"可知,这种滑板其实很难被控制.故选C.
13.C 考查细节理解.根据"Amazon in the United States now only sells hoverboards from brands that have submitted safety standrd documents"可知,悬浮滑板仍然在美国的亚马逊上销售.故选C.
14.A 考查词意猜测.根据文章内容可知,研究表明,一些悬浮滑板品牌的电池或插头存在缺陷.所以该词的意思是"有缺点的".故选A.
15.A 考查文章题材.根据文章内容可知,这是一篇新闻报道,所以最有可能在新闻报纸上看到这篇文章.故选A.

点评 阅读理解考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.

11.Your mobile is now much more than just a communication device-more like a remote control for your life.You still call it a"mobile"from habit,but it is an organizer,entertainment device,payment device and security(安全) center,all developed and manufactured by engineers.
What we do need is better mobiles and more intelligence.Because it knows your travel timetable it can check for problems on the roads or with the trains,giving you the best route into work.It can control your home,reprogramming the central heating if you need to get up earlier and keeping an eye on your home by connecting your mobile with the home security system.It is your payment system-you can pay for tickets for journeys or buy items in shops by placing the phone near a sensor(感应器).With an understanding of location,the mobile can also provide directions,or even tell you if your friends or family are nearby.
Usually it will start work even before you wake.It will work with your home entertainment system while you sleep to find programmes that will interest you and download them as a podcast to watch on the train or in other spare moments.It will intelligently work out what to do with incoming phone calls and messages.Because it knows your diary it will also know,for example,to direct voice calls to voicemail when you are in a meeting,perhaps providing a discrete text summary of the caller and the nature of their call.
With its understanding of almost all aspects of your life; many new services become possible.For example,a"Good Food"meal planning service could send daily suggestions for your evening meal based on learned preferences,previous selections made and the likely contents of your refrigerator.
Ten years ago the mobile was purely a device for making voice calls.Now it is a camera,MP3player,and texting device.This is only the start of an evolution that will turn it into our trusted and indispensable companion in life.

15.Stonehenge is probably the most important prehistoric monument in Britain.The Stonehenge we see today is the final stage that was completed about 3,500 years ago.
The first Stonehenge was a large earthwork,consisting of a ditch(沟),bank and the Aubrey holes,all probably built around 3,100BC.The holes themselves were not for the purpose of graves,but as a part of religious ceremony.
The second stage of Stonehenge started around 2,150BC.About 82 bluestones,some weighing 4tons each,is thought to have been carried by water along the south coast of Wales and up the rivers Avon and Frome,before being dragged overland again to near Warminster,about 6miles away.The final stage of the journey was mainly by water,down the river Wylye to Salisbury,then the Salisbury Avon to west Amesbury.These stones were set up in the center to form an incomplete double circle.
The third stage of Stonehenge,about 2,000BC,saw the arrival of the Sarsen stones,which were almost brought from Avebury,about 25 miles north of Stonehenge.
The final stage took place soon after 1,500BC when the bluestones were rearranged on the horseshoe and circle that we see today.

29.How long has Stonehenge existed?D
A.About 1,500years.
B.About 2,000years.
C.About 2,500years.
D.About 5,000years.
30.What was the probable use for the Aubrey holes?D
A.They were used as graves      
 B.They were used to attract tourists.
C.They were used to hide precious stones.
D.They were used for religious activities.
31.Which of the following places is nearest to Stonehenge?C
A.Warminster.
B.Salisbury.
C.Amesbury.
D.Avebury.
32.What does the text mainly talk about?B

科目:高中英语 来源:海南省2016-2017学年高一下学期期中段考英语试卷 题型:阅读理解

My grandparents believed that you were either honest or you were not. They had a simple saying hanging on their living-room wall: “Life is like a field of newly fallen snow. Where I choose to walk every step will show.” They didn’t have to talk about it; they showed this truth by the way they lived.

They understood that honesty is an inner(内部的) standard for judging your behavior. Unfortunately, honesty is in short supply today. But it is the real bottom line in every area of society and a discipline (自制能力) we must demand of ourselves.

There’s a story told about a surgical nurse’s first day on the medical team at a well-known hospital. She was responsible(负责) for all surgical instruments and materials during an operation. At the end of the operation, the nurse said to the doctor, “ You’ve only removed 11 sponges(海绵), and we used 12. We need to find the last one.”

“I removed them all,” the doctor assured her. “ No, you didn’t , sir,” insisted the nurse. “ Think of the patient.”

Smiling, the doctor lifted his foot and showed the nurse the twelfth sponge.

So when you know you’re right, you can’t yield. Don’t be afraid of those who might have a better idea or who might even be more intelligent than you are.

Self-respect and a clear awareness (意识)of right and wrong are powerful parts of honesty and are the basis for enriching your relationships with others. Honesty means you do what you do because it’s right and not just fashionable or politically correct. A life of principle, of not easily yielding, will always take you forward. My grandparents taught me that.

1.From the first two paragraphs, we can infer that ______.

A. the author’s grandparents liked snow

B. the author’s grandparents didn’t like chatting

C. the author is worried about the issue of honesty in today’s society

D. Honesty is the most important standard for judging one’s behavior

2.The nurse insisted there was still a sponge because_____

A. she saw the doctor hide the twelfth sponge

B. she believed she was right

C. she thought the doctor was not responsible

D. she knew the patient well

3.What does the underlined word “yield” mean in the text?

A. admit B. give in

C. stop D. look forward

4.How does the text mainly develop?

A. By providing an example of honesty.

B. By making a comparison between honesty and dishonesty.

C. By explaining the author’s grandparents’ belief in detail.

D. By following the order of importance.
