2015德州二模英语试题及答案(3)

B
Four years ago，a lobster(龙虾)fisherman，Gary Nichols，had never seen a lionfish，but today his traps are full of them．He catches so many lionfish now that he’s started to sell them．While his lobsters sell for $16 per kilogram，lionfish only make him $12. Lionfish are causing a great concern on his business and the commercial fishing industry in Florida，threatening other fish populations—in some cases reducing them by up to 90％．    
Lionfish are native to the Indian and Pacific Oceans，but were accidentally introduced into Atlantic and Caribbean waters during the 1990s．With no natural enemies in the Atlantic and an ability to reproduce year-round，plus the favorable environment，their numbers have been rising in recent years．
Not only are lionfish causing losses to lobster fishermen like Nichols，they are also threatening the balance of the fragile ecosystem．
“Lionfish are eating almost anything that fits in their mouths．”says Lad Akins，director of REEF，a marine conservation group．“Some are commercially valuable fishes，like grouper and snapper that the fishermen depend on．Lionfish even could result in the extinction of some fish．”
In an effort to solve the problem，REEF runs a monthly contest，awarding prizes to those who catch the most lionfish．It also runs workshops educating divers about safe collection and removal techniques．Many volunteers have also joined the fight with a campaign that encourages people to eat lionfish．
“If we can’t beat them，let’s eat them!”said Michelle Kosiek，the manager of the Fish House Encore，which has been serving lionfish for the past 18 months．“There is a little bit of fear factor eating them．In fact，those who tried it have spoken well of it．”

A．the overpopulated lionfish are affecting Florida fishermen

Harry Potter and The Hunger Games haven’t been big hits for nothing．Lots of teens and adolescents still read quite a lot．But a study shows a clear decline over time．Nearly half of 17-year-olds say they read for pleasure no more than one or two times a year，and that’s way down from a decade ago．
The digital revolution means there are more platforms than ever to read on．Jim Steyer has been studying the effect of technology on children，and he finds the results striking．Steyer has four kids and has seen the trend most with his 16-year-old．
“I start to see it in our 10-year-old，because he is less and less reading，and more and more attracted to some of the digital media platforms that he has access to．”he says．
Researchers want to know more about how teens are spending their time in the digital age．But Kathryn Zickuhr of the Pew Research Center says it’s tricky．If a kid is looking at a book，you can assume he or she is reading．But when it comes to looking at a smartphone or tablet，who knows?
“We’ve heard from middle and high school teachers that sometimes the Internet is wonderful for highly motivated students to do deep and expansive research，”says Zickuhr．“But on the other hand，obviously there are many distractions(干扰)on the Internet．”    
“Despite those distractions，parents can do a lot to promote reading．Kids with parents who read，who buy or take books out of the library for their kids，and who then set time aside in their kids’daily schedule for reading，tend to read the most，whether it’s on a book，an e-book or some other devices．”Jim Steyer says．
29．What does Jim Steyer see in his four kids?
A．They become addicted to magic novels．
B．They read for pleasure more frequently．
C．They spend too much time on electronic devices．
D．They get their reading ability improved on the Internet．
