January is a peak time for downloading health and fitness apps and putting those Christmas present fitness trackers to work. But do they actually help you keep to it?

After the Christmas fulfillment of delicious food comes the New Year’s decision to get fit, lose weight, and eat more healthily. But while 65% of us decide to lose weight, only 12% successfully keep to it. Can tech help?

When Sarah, 34, a law professor from Australia, wanted to lose weight last year, she took the unusual approach of placing bets that she would achieve her exercise goals. Breast cancer had stopped her exercise routine, and she’d gained weight during a year which included three operations, she says. “I was returning to exercise by hiking and trying to lose some of the weight I’d put on while being sitting for long,” she says. She began a new exercise routine eight weeks after finishing the surgery. With a wearable activity tracker, she could see how many steps she took each day and how many calories she burned.

But she also motivated herself with an app, Step Bet, that let her know whether she would achieve her exercise goals. “I did three one-month bets and three six-month bets, and lost 7kg—10% of my body weight,” says Sarah. She also says she made £358. “I like losing fat. I don’t like losing money. The effect? Motivation!” she explains.

For the data-minded, tracking your progress with lots of measurements is enough to stay motivated.

1.What can we learn from the second paragraph?

A People can only have delicious food at Christmas.

B You can turn to tech if you want to lose weight.

C Many people want to lose weight but few succeed.

D Most people are overweight because they eat too much in winter.

解析：选C。推理判断题。根据第二段第二句But while 65% of us decide to lose weight, only 12% successfully keep to it.可知65%的人都决定减肥，但是只有12%的人能够坚持下来，由此推之想减肥的人多，能成功的人少，故选C。

2.Which of the following can replace the underlined word “approach”?

A Task.

B Way.

C Road.

D Success.

解析：选B。词义猜测题。根据后文可知Sarah采取了一种不同的方式来减肥，因此approach应意为“方式或方法”，故选B。

3.Why did Sarah stop her exercise routine?

A Because she had a serious disease.

B Because she was too busy.

C Because she didn’t have a proper goal.

D Because she couldn’t keep to it.

解析：选A。细节理解题。根据第三段第二句Breast cancer had stopped her exercise routine, and she’d gained weight during a year which included three operations, she says.可知是因为得了乳腺癌所以Sarah才终止了锻炼，故选A。

4.How many kilos did Sarah weigh before she lost weight?

A 50 kg.

B 63 kg.

C 70 kg.

D 77 kg.

解析：选C。推理判断题。根据第四段第二句I did three one-month bets and three six-month bets, and lost 7kg—10% of my body weight.可知Sarah减了7公斤，是她体重的十分之一，因此减肥前重70公斤，故选C。

5.In which column of a newspaper can you see this passage?

A Science.

B Culture.

C Health.

D Sports.

解析：选C。推理判断题。根据文章内容很少有人减肥成功，也许借助技术可以帮助减肥以及Sarah的减肥成功案例可知本文主要是讲如何保持健康体态、如何运动减肥的，应该属于健康板块，故选C。
