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.

7.There are a lot of people who are overweight all over the world.What causes obesity?If you get the gene(基因),well,probably you are going to be a few more pounds heavier compared to the rest of your classmates or friends.(36)GObesity can not only make a person look heavy,and not in the usual sense of being handsome,but can also lead to serious health conditions and life-threatening diseases.
(37)CIndeed,junk food has been blamed for the prevalence(流行)of obesity.It is called junk food,because hamburger,pizza and the like contain high calories.If you eat a Big Mac (a super hamburger),an order of large fries,and a large Coke,you will need to walk non-stop for six hours to burn off the calories you have gained.And don't be fooled by soft drinks,which are high in sugar and are a major cause of obesity.
(38)FPopular sugary drinks,of course,include Coca Cola,Pepsi(百事) Cola,and many new brands that appear on the market every couple of days.
(39)BJust one 20-ounce (about 567g) bottle of soda can have 250calories,which are equal to more than 16teaspoons of added sugars.Even a lemon-flavored iced tea can have 210calories.
(40)ENext time,when you are ready to eat that huge Mac and to drink that two-liter bottle of Pepsi,probably it's a good idea to give it a second thought.

A.Obesity is more common in women than men.
B.Most people don't realize how easy it is to gain weight from drink sugar-sweetened beverages(饮料)
C.When we talk about obesity,the first thought that comes to mind is:junk food.
D.The unburnt calories will put weight on you.
E.Keeping healthy is our own responsibility.
F.Because of their high content of sugar,soft drinks are also called sugary drinks.
