But the group saw many of their health markers improve. They8.(lose)body fat, their blood pressure fell slightly, and they had better blood sugar control. Meanwhile, another 75 healthy adults 9. did not practice caloric restriction saw no 10. (improve)in these markers.

Like bootcut jeans or farm fresh produce,television is proving its staying power regardless of trends. It seems to be just like a home cooked meal,never to be replaced,thanks to the wide application of big data.
Americans are still watching an average of five hours of TV each day and over 50%of homes have a television subscription service like Netflix or Hulu.This is due to the fact that television programming has undergone a renaissance(复兴),with cinema-quality programs on broadcast,new ways of delivery-Netflix or Hulu and other over-the-top(OTT)providers and now the promise of data-driven insights for advertisers. Data is the key to television's profitability.Advertisers have access to more audience information than ever,while networks and content providers use data,in addition to instinct(本能)to guide programming decisions.The abundance of data available to content providers,marketers and advertisers makes it possible to process,analyse and transform big data into profitable,useful insights.
For those 50% of homes with a subscription service,OTT TV is using data to make decisions not just about programming,but to guide viewers to the right content.The most famous example of data-driven content is Netflix's House of Cards,a popular TV series in America,designed to be a hit based on platform data like user viewing habits,ratings and preferences.But the content provider uses data to guide all of its decisions,ranging from title images to homepage layouts.
Netflix receives data from millions of set top boxes and online accounts,and then processes data using real time technology like Spark.These data have led to clearly-seen results,like a 20%-30%increase in programs'viewship numbers.

You wake up,ready to seize the day,when an unexpected breakfast is served your way-a classic sandwich.Someone has decided to park their rust-bucket in your driveway,blocking you in.Is it illegal to park in front of a driveway?Yes,absolutely.But some folks love to"stick it to the man”.And now,you can stick it to them.We have a general disgust toward tow trucks( 拖 车 ),their drivers,and the industry as a whole.However,it's a necessary evil,and in certain applications,completely justified.This is one of those times.Take delight in it!
But remember this:if you want to have someone's car towed,call the police and have them handle it.Why call the police first?Because in the event that the owner loses his/her car and tries to sue(起诉)for damages or lost wages,you're removed of the situation and free of any responsibility.If you call a tow company directly,they may give the owner your information.And building a backyard Thunderdome(雷霆)to settle your differences in"the old-fashioned way”can be costly.
So,can you park in front of your own driveway?Unfortunately,parking in front of your own driveway is still technically illegal.The sidewalk and curb in front of your house is still city property,and determining who exactly is parking in front of the driveway is next to impossible for parking enforcement ( 执 法 ).There are reports of many neighborhoods only receiving a ticket for parking in a driveway if someone calls to report it,so it depends how risky you're feeling.Here in L.A.,I see a handful of cars on my block consistently block their own driveway.I have rarely seen them ticketed or towed,but if it were me,I'd keep searching for a real spot.
1.What's the tone of Paragraph 1?
A.Humorous. B.Serious.
C.Sympathetic. D.Modest.
2.What is advised to do when you find a car blocking your driveway?
A.Call the police.
B.Turn to a tow company.

D.Use the old-fashioned way.
3.Why do people park on their own driveway?

B.It is not against the law.
C.They like taking risks.
D.Finding a parking spot is hard.
The hero of The Good Doctor,a young surgeon with autism(自闭症),represents the show's title in more ways than one.In the show,Dr.Shaun is extremely skilled at curing patients,but he's also morally good,able to see the light in others even if he can't always connect.
“As a British,I'm probably quite cynical(愤世嫉俗)in general,"said Freddie,who plays the part of Dr.Shaun,during a recent interview on the show's set in Metro Vancouver."I think he's a lovely person. Getting to reflect that version of the world he sees or he believes in and his faith in humanity,I think,is great,especially at a time like today when there's so much negativity."
Through Shaun and other doctors at the fictional San Jose St.Bonaventure Hospital,the series explores what it means to be a good person,which impresses the viewers greatly."It brings people hope in dark times and that might be one reason why it became a runaway hit last year,"cast members said.
"It came about somewhat naturally,"Freddie said."It seemed unusual to me to put so much in the four,five months of filming,because we only did 10 episodes,and then sort of stepped away and did nothing...I wanted to live in that world longer.”
Freddie,26,admitted to feeling some anxiety about getting his performance right.He did a great deal of research on autism and continued to work with a full-time consultant."When you're opposite Freddie, Shaun is learning.Shaun is processing."Nicholas,who plays Dr.Melendez,commented."It's not impression.He doesn't slip into the character and play around.He lives it a lot,too."
1.Who acts the hero in The Good Doctor?
A.San Jose. B.Shaun.
C.Freddie. D.Nicholas.
2.What is particularly impressive in the hero of The Good Doctor?

A.How the actors play the roles.
B.How people react to the show.
C.What makes the show a big hit.
