Running on the beach can certainly be a good thing.It's completely different from running on the pavement，a track or trails with soft surfaces.
   For starters，sand can be a challenge because it has an uneven（不平的）surface and constantly moves under your feet.As you push off，you're going to lose some of your push as the sand moves.So，you're not going to be able to push yourself forward as you would on a track or pavement!But this unevenness has an upside：It gives your body an extra workout，forcing you to exercise muscles that don't get as much use during runs on firm surfaces.
   You also might feel painful afterward because beaches tend to slope（傾斜）downward，toward the water.If you're going for a long run on the beach，you might notice that one side of your body-including your ankle，leg or knee-might feel more painful because you're putting more pressure on it due to the slope.
   Some beach runners tend to run barefoot.However，if you're not used to barefoot running，start slowly and run short distances at first.That's because running barefoot uses different muscles than running with shoes does，and it's important to strengthen these muscles and adapt your feet.
   Despite these challenges，running on sand can be a smart choice for athletes because running on it can decrease the bad influence on your body during high-intensity workouts.This could potentially lead to less muscle damage and less pain.Women had less myoglobin（肌紅蛋白）-a protein that can be a sign of muscle pain-in their blood after running on the sand than they did after running on grass.This suggests running on softer ground surfaces，such as sand，may reduce muscle damage.

（1）What makes running on sand difficult for starters？
B
B

A．The smooth surface.
B．The moving surface.
C．The sloping surface.
D．The hard surface.
（2）Which of the following best explains "upside" underlined in Paragraph 2？

B．Reason.
C．Surprise.
D．Challenge.
（3）What should you avoid when trying running barefoot？
D

C．Developing some muscles.
D．Running long distances.
（4）What is the benefit of running on sand to women？
C

1．When it comes to making healthy lifestyle changes，which should come first-changing your diet or becoming more physically active？
   Previous studies suggested that providing people with too much information about nutrition and physical activity at once tends to be discouraging.That has led to the popularity of advising people to make changes gradually，and set smaller goals.
   So the scientists divided 200 inactive participants who were age 45 or older into four groups.One group was instructed about making diet and fitness changes at the same time，the second group was taught about diet changes first，then fitness changes four months later，the third group changed their exercise habits first and made changes in their eating habits four months later，and the final，control group was not instructed about either diet or fitness changes but about how to manage their stress.
   The researchers tracked the groups for a full year.Compared to the control group，the three intervention（干預(yù)）groups made healthy changes in their diet.Those who changed their fitness habits first significantly increased the amount of exercise they received daily compared to the other groups after four months.However，at the end of the year，the group that changed both diet and exercise at the same time was the only one that met the nationally recommended targets for both exercise and nutrition levels，while those who worked on improving their nutrition first were unable to meet the recommended levels of fitness after a year.The researchers suspect that changes to diet are easier to make than changes to physical activity.
   The findings show，however，that pairing diet and exercise changes may help to overcome some of the barriers people face in adding more physical activity into their lives.If folks change diet and exercise orderly，the scientists say，they may end up placing more importance on the first set of behavior changes and feel less pressured to address the second set.

（1）The advice mentioned in the second paragraph seemed

.
A．popular
B．dangerous
C．scientific
D．unsatisfactory
（2）Which group made progress earlier than other groups in increasing the amount of daily exercise？

A．The first group.
B．The second group.
C．The third group.
D．The control group.
（3）The reason why those improving their nutrition first failed to meet the levels of fitness after a year might be that

.
A．they might be very lazy
B．they wouldn't like to change their behavior
C．it is much harder to change physical activity
D．they might put on weight before changing their physical activity
（4）Which of the following does the author probably approve of？

A．Pairing diet and exercise changes.
B．Becoming more physically active first.
C．Changing diet and exercise following a fixed order.
D．Changing diet first and placing more importance on it.

2．Hunger has been troubling the world.In 2016，the number of hungry people in the world reached one billion for the first time.It's difficult not to be shocked by the fact that more than one in seven people in the world do not have enough to eat.
   The UN figures that almost two thirds of the world's hungry people are in Asia，which is of course the world's most populous continent.More than a quarter are in sub-Saharan Africa.Although this place has a much lower population than Asia，it has the highest percentage of hungry people.Almost all of the rest are in Latin America，North Africa and the Caribbean.
   There are many reasons for world hunger.They include wars，droughts，floods，and the overuse of farmland.All these factors affect food production.Many people also blame greedy businessmen for pushing up the prices of basic foods in the global market.In fact，many people are starving just because they're poor.Therefore，the most important reason，quite simply，is poverty.If we can't pull out this root，we'll never be able to solve food shortage.
   Although many people make the obvious point that there would be less hunger if the global population were smaller，few people would argue that there is not enough food to go around.The basic problem seems to be not a lack of food，but its distribution.In the last 50 years，global food production has risen even more quickly than the global population.
   There are many areas of the world in which people generally have more than enough food.In those places，being overweight is a far bigger problem than hunger.The answer to world hunger，therefore，may be a balanced food distribution around the whole world.Everyone will have enough to eat，but not to overeat.

（1）14.Which continent has the highest rate of hungry people？

A．Asia.
B．Africa.
C．America.
D．Europe.
（2）15.According to the last paragraph，

results in the poverty.
A．not enough production
B．slow growth of food
C．consuming too much food
D．imbalance of food distribution
（3）16.Maybe the author would write about

if there were a sixth paragraph.
A．how to make food distribution balanced
B．when to get rid of world hunger thoroughly
C．who is to blame for the world hunger
D．what to do to help the hungry people
