You probably know that frogs hop ( 双足跳 ). But did you know that there’s a small frog in the Pacific Northwest that bellyflops(肚子先着水)? It’s called a tailed frog.
Dr.Rick Essner, who has been studying tailed frogs for the past few years, says, “ I’ve looked at thousands of jumps and have never seen them land on their feet like other frogs.” Most of the time, tailed frogs land on their stomachs and then bring their back legs in to prepare for another jump.
Essner forst noticed these frogs because of the way they swim. Other frogs kick both of their back legs at the same time. But when a tailed frog swims, it pushes first with one leg and then the other.
To try to find out why tailed frogs bellyflop, Essner and other scientists collected and filmed different kinds of frogs. They found that all of the frogs start their jumps the same way: they hold out their legs. The change comes in the landing. Tailed frogs can't move their back legs as quickly as other frogs do. Maybe they don’t need to. Tailed frogs live around water and quickly jump into the water to escape danger.
Early frogs developed around watery areas and could jump quickly into the water to escape danger. Scientists think those frogs blended in with (与…融合在一起) the green plants on the side of the rocky rivers, just like today’s tailed frogs. “Iwould guess that other animals would have problems detecting them, ” explains Essner. When other animals find those early frogs, the frogs could jump into the river. They didn’t need to continue hopping.
Tailed frogs and other kinds of frogs went their own ways about 200 million years ago. Tailed frogs stayed by rivers. Other kinds of frogs moved to places where new hopping skills allowed them to survive.
1. What’s special about the detailed frog ?
A. It has a long tail
B. It jumps on one foot
C. It stars its jump differently
D. It lands differently from other frogs.
2. Why do tailed frogs bellyflop?
A. They have never left the water to live .
B. They have trouble in holding out their legs
C. Their back legs can’t catch up while jumping..
D. Their front legs develop better than the back ones.
3. The underlined word “detecting” in Paragraph 5 means “______”.
A. eating B. killing
C. using D. discovering
4. When they are in danger, the detailed frogs would _________.
A. jump into the water for protection
B. hop around quickly

You probably know that exercise is the key to reducing depression, but you might not know why. Here are some tips for exercising when you’re depressed.
Change your view of “exercise”.
Forget “exercise”. Instead, think “being active” or “having fun”. 1. Besides, it gives you a bigger benefit.
2.
Taking part in physical activities with others supports you in doing those activities. Ask friends what activities they’re doing or they would like to start doing, and join them. Other choices include hiring a personal trainer, joining an exercise group or going to a class.
Try an experiment.
3. Or go to the gym every Monday, Wednesday and Friday. Even if you’re feeling too tired to do any actual exercise, still go to the gym, park your car, walk in, chage into workout clothes, and pick up a 5-pound weight. If you’re really so tired that you don’t want to do anything else, that’s totally fine.
Take it outside.
Nature has a great effect on our feeling and decreases depressive symptoms. Even just looking at images of lakes and trees helps. 4. Or walk on a treadmill (跑步机) by a window.
Tie it to a goal.
Korb said, “When you connect your exercise to a long-term goal, it helps your brain forget momentary discomfort and makes your exercise more satisfying.” For example, Korb started getting active because it made playing sports more enjoyable. Figure out what’s truly important to you. 5.
A.Move with someone else.
B.Sign up and go to exercise classes.
C.It’s a lot easier to do something simple.
D.Remind yourself of your goal regularly.
E.Remember your partner to keep you company.
F.Take a walk around your neighbourhood or a local park.
G.This increases your chances of actually moving your body.

So you think you know your dog. But how well does your dog know you? She probably recognizes you when she sees you. But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face? Researchers in Austria have taught pet dogs to know the difference.
Dogs are very mindful of sound. When dog owners shout or speak in a strong, unkind voice, dogs often act ashamed and quietly move away from the area.
Recently, researchers found that dogs can look at our faces, and tell the difference between a smile and a frown(皱眉). The animals were able to recognize a look of praise from one of blame.
Researchers at the University of Veterinary Medicine, Vienna performed a series of experiments. They taught dogs to recognize facial expressions. They showed the dogs two pictures of either the upper or lower half of a person's face. On one picture, the person looked happy. The other appeared angry.
The dogs were then shown images of the eyes or mouths of people they had never seen before. They were also shown the left half of the faces used in training.
Corsin Muller led the study. “We were really speaking, do they realize that smiling eyes have the same meaning as a smiling mouth, or angry eyes have the same meaning as an angry mouth? And it turned out that they really did perform very well in these research experiments.”
Once the dogs learned to recognize which image was happy or angry, they could easily find the same expressions in pictures of any face.
Corsin Muller says future studies will try to show whether dogs can learn the meaning of facial expressions―for example, whether a frown shows that someone is angry.
In the experiments, researchers found the dogs were slower to link a reward, or prize, with recognition of the angry face. This suggested that dogs had an idea people with angry faces were best avoided.
1.What does the passage mainly tell us?
A. How one can know his dog well.
B. How a dog can probably be well trained.
C. How a dog can tell one something.
D. How a dog can know one’s expressions.
2.Hearing its owner’s strong, unkind voice, a dog is likely to_________.
A. jump happily B. act excitedly
C. escape quietly D. shout loudly
3.A dog is able to recognize one’s __________.
A. praise B. blame
C. anger D. all of the above
4.What can we learn from the passage?
A. Dogs are as clever as human beings.
B. Dogs can understand man’s feelings.
C. Dogs can be trained to do everything.
D. Dogs can learn to make any angry face.

“Of course it seems likely that they would associate (联系)some positive meanings with the smiley face and they would associate some rather negative meanings with the angry face. But what exactly they are associating with these expressions we cannot know at this point.” Corsin says.

You probably laugh at something you find funny, but how much do you really know about jokes and humour? Reader's Digest (RD) questioned several experts to give us some facts about them.
RD: What’s the oldest joke in the world?
“We can't know the oldest joke in the world because it would have existed earlier than writing,” says Christie Davies, professor of sociology at the University of Reading in the UK. The oldest joke book that's been found so far is the Greek Philogelos. It dates from the 4th century AD, although the jokes date from an earlier time. According to psychologist Steve Wilson, director of National Humor Month (April in the US), it contains 265 jokes.
RD: Do some people fail to develop a sense of humour?
Rod Martin, professor of psychology at the Western University in Canada, believes that while everyone is born without a sense of humour, as we develop, humour and laughter begin to appear. “Of course, some children are more serious, quiet, and less likely to laugh frequently, but this doesn't mean they don't have a sense of humour.” And according to Steve Wilson, there are no adults who don't have a sense of humour. “Almost everyone is able to develop a sense of humour, and I teach people how,” he says.
RD: Do people share a sense of humour unique to their own nation?
Sense of humour does differ a lot by country, according to an author named Scott Weems. British humour is thought to be absurd (荒谬的) in nature, while American humour has an aggressive quality. According to a study, Germans are found to find everything funny.
1.What do we know about the oldest joke book?
A. It remains unknown. B. It was written in Greek.
C. It was found in the UK. D. It contains the oldest joke.
2.What does Rod Martin agree with about people's sense of humour?
A. Nobody is born with a sense of humour.
B. Some adults lose it when they grow up.
C. Childhood is the best time to develop such ability.
D. Children have a poorer sense of humour than adults.
3.What kind of humour has an aggressive feature?
A. British humour. B. German humour.
C. Canadian humour. D. American humour.
4.Where can you probably find the text?
