People often talk about how difficult it is to keep a healthy lifestyle while on vacation. A cruise （船）is the perfect example--too much food and too little exercise.1.Then I realized that’s of taking such vacations, we would all be better off taking vacations that encourage healthy behavior. Things like hiking and cycling are not only healthy, but they're cheap! 2.－we couldn't afford to do such else!
Gerhard Strauss-Blasche and colleagues examined the links between vacation environment and recovery. 3. They filled out questionnaires within two weeks of returning from a short vacation. Post-vacation recovery was assessed by quantifying how closely subjects agreed with the statement "In comparison with the two weeks before vacation, I now feel mentally fitter, feel more balanced and relaxed, can concentrate better during work, feel physically fitter, and do my work more easily.”
4.?Physical activity during the trip was positively associated with post-vacation recovery scores. In other words, the more physically active people were during their vacation, the more likely they were to feel relaxed upon their return. 5..In fact, I wouldn't take this study too seriously. But I don't think it's surprising that people who engage in(参加）healthy behaviors during a vacation might feel better upon their return. So instead of looking at your vacation as a potential block to your healthy lifestyle, why not look at it as a chance to improve your healthy behaviors?
A.I thought a lot about this issue
B.So what did the researchers find
C.Now of course this is only one study
D.The study included 191 German males and females
E.That's why my wife Daun and I first started taking cycling vacations
F.Limited evidence supports the idea that healthy vacations leave you feeling better
G.Why would people choose to eat unhealthy food and perform very little physical activity
Universities have finally promised to end grade inflation(膨胀)after a growing number of first-class degrees led to accusations of dumbing down.The percentage of firsts handed out has doubled in the last decade,with 24 percent of graduates now awarded the top grade,compared with 12 percent in 2008.
Universities UK(UUK)is today promising for the first time to handle the problem and check the endless rise in the number of firsts dealt out.
Education Secretary Damian Hinds welcomed the move and warned any university producing an unreasonable rise in top degrees will face intervention(介入)from the regulator Office for Students.He said artificial grade inflation ust be stopped and warned quality must not be cast aside to build up an institution's reputation.
As part of a package of measures,universities have agreed to follow a new framework specifying what a student must demonstrate(展示）to achieve a certain grade.They have promised to ensure the standards will stretch and challenge all students,and protect the value of qualifications.
It comes after UUK admitted for the first time in November that tutors may be under pressure from both students and their bosses to inflate degree results.Staff may be tempted(诱惑)to hand out more top marks because they fear bad reviews in student feedback surveys,it said,while institutions could be motivated to do so to improve their position in national rankings.
Critics have long warned the trend weakens employers confidence in the system,as they cannot pick out outstanding candidates to hire.
A UUK investigation discovered 43 percent of first-class degrees last year were likely to have been awarded due to factors such as grade inflation.
Professor Dame Janet Beer,president of UUK,said,"The UK higher education sector has a world- leading reputation,so it is critical to protect the value of a university degree." UUK's promise will be in place for the 2019-2020 academic year.

The race to 5G is on. All four major US carriers now have some form of 5G wireless, although it’s all limited roll-outs in only a few cities, mostly using expensive phones that won’t support future nationwide 5G networks. We’re tracking the roll-outs monthly on our Race to 5G page.
The early 5G roll-outs are more like a public test than a final product. AT＆T, Verizon, and T-Mobile are all using technologies that only travel about 800 feet from a cell site, which means there isn’t much coverage. All four carriers are waiting for upgrades（升级）to their base stations that will improve coverage, speed, and reliability. Around the end of this year or the beginning of 2020, AT＆T, Verizon, and T-Mobile all intend to launch 5G networks that use the existing 4G spectrum（频谱）, which will have slower speeds but broader coverage.
We’ve tested AT＆T in Dallas and Las Vegas Sprint in Dallas and New York; Verizon in Chicago, New York, and Providence; and T-Mobile in New York. Every month, we’ve been seeing better performance and more new devices. It’s messy. It’s very early days. And if you like new technology, it’s very exciting.
In previous mobile transformations, we’ve seen most of the big changes happening years after the first announcement. Take 4G, for instance. The first 4G phones in the US appeared in 2010. But the sorts of 4G applications that changed our world didn’t appear until later. So following that plan. While we’re getting a little bit of 5G right now, you should expect the big 5G applications to crop up around 2021 or 2022.
5G stands for fifth-generation-cellular（蜂窝状的）wireless, and the initial standards of it were set at the end of 2017. But a set of standards doesn’t mean that all 5G will work the same-or that we even know what applications 5G will enable. There will be slow but responsive 5G, and fast 5G with limited coverage.
1.What is the present state of 5G in the US？
A.Initial exploration. B.Great improvement.
C.Wide application. D.Extensive promotion.
2.Why does the author take 4G for example？
A.To persuade carriers to give up 5G.
B.To remind people of 4G’s importance.
C.To prove 5G takes time to make a greater difference.
D.To show 5G has failed to meet expectations.
3.What’s the author’s attitude to 5G？
A.Cautious. B.Skeptical.
C.Opposed. D.Objective.
4.What’s the best title for the text？
A.Race to 5G B.5G is coming
C.How fast is 5G？ D.What is 5G？
