The Chinese mainland’s box office hit an all-time high with a total of 63.7 billion yuan (around 9.1 billion U.S. dollars). It remains a difficult task，3., for Chinese films to appeal to North American moviegoers and achieve similar success 4. national borders. Chinese films have long faced 5. uphill, cross cultural challenge to break the code regarding what attracts international interest. Frequent 6.(complain) about Chinese film range from “too different to identify with,” or “too long and confusing,” or simply “too Chinese.” The difference in stories and storytelling styles is significant, because Chinese stories unique to China are 7.(familiar) in the West. Hollywood producer Jeff Most told Xinhua, “These are rich cultural traditions China wants to share but they need 8.(introduce)to Western audiences in a way 9. highlights the universal aspects of the story that everyone can all relate to, rather than the different cultural references that are 10.(confuse) to the westerners.”

    Nowadays, many of us track our steps with smart watches, pedometers (计步器) or phone apps and are of course thrilled when we reach that all-important daily goal of 10,000 steps. You might_______that this number has appeared after years of research.

The_______number ''10,000'' dates back to a marketing campaign_______shortly before the start of the1964 Tokyo Olympic Games. A company began_______a pedometer called the Manpo-kei: ''man'' meaning 10,000, ''po'' meaning_______and ''kei'' meaning meter. It was hugely _______and the number seems to have stuck. Many buyers are appealed by the new device.

Since then, studies have_______the health benefits of 5,000 with 10,000 steps and, not _______，the higher number is better. But until recently, all the_______between hadn’t been studied. I-Min Lee, a professor of________at Harvard Medical School, and her team________a group of more than 16,000 women in their seventies. Each woman spent a week________a device to measure movement during________hours. When they________the women up an average of four years and three months later, 504 died. How many steps do you think the people alive had been doing? In fact, the average number for________was only 5,500 but not 10,000. Women who took more than 4,000 steps a________were significantly more likely to still be alive than those who did only 2,700 steps. It's surprising that such a small________could have consequences for longevity (寿命).

However, physical conditions________from person to person, and we should do it wisely. So count if you find it ________ you, but remember there’s nothing special about 10,000 steps. Set the goal that is________for you.

Do Actions Speak Louder than Words?

Our society is fast paced. We are all rushing from one place to the next, blowing our horn at slow drivers who may be singing songs in the car with their children or pointing out some interesting sights. We don't have time for that silliness today. But we try to say to ourselves that we will make time for fun tomorrow. It is time to take a few deep breaths and think about our actions and our words. 1.

Have you ever really thought about the saying “Actions speak louder than words”? Think about it now. If you say one thing and act in an opposite way, will the words be ignored and just the actions remembered? I don’t think so. 2. It is also equally important to use words to show appreciation, love, approval and happiness and then follow those words with a hug, pat on the back or smile.

3. What about that saying? True? Yes! Words carry a lot of weight and will be remembered for years especially when they are written down. Mean words can hurt for that moment and for a lifetime. I am sure that each of us remembers a time when a friend made an unkind comment. 4. Let’s not be a member of that “club”. When was the last time that you hid a love note in a lunch box or in your mate’s coat pocket? If you want to see a bright smile, that will do it! The power of this written note will be remembered for many days, even years.

“I can live for two months on a good compliment(夸奖)”, said Mark Twain. Children grow stronger when they feel appreciated and understood. 5. A perfect way to turn a bad day around is to praise your child. “I noticed that your hair looked very nice today.” “Did you hang your coat up all by yourself?” It is amazing how those few words can change a child's outlook... almost immediately. Don’t stop there... One of my sisters ended a phone conversation with three words －“I love you”! Boy, that put a spring in my step! Mark Twain is right. I still feel the positive effect of those three little but very powerful words.

A.The pen is more powerful than the sword.

B.Is it really reasonable to do something like that?

C.Do they display the attitude that we want to convey?

D.It is important to have your words match your actions.

E.Behavior is a mirror in which everyone shows his image.

F.Those words did lasting damage to you, the relationship or both.

G.Don’t be afraid to shower your child with encouraging words all day long.

    How does an ecosystem(生态系统)work？What makes the populations of different species the way they are？Why are there so many flies and so few wolves？To find an answer，scientists have built mathematical models of food webs，noting who eats whom and how much each one eats.

With such models，scientists have found out some key principles operating in food webs. Most food webs，for instance，consist of many weak links rather than a few strong ones. When a predator(掠食动物)always eats huge numbers of a single prey(猎物)，the two species are strongly linked；when a predator lives on various species，they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species，it can survive the extinction(灭绝)of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare，the switch allows the original prey to recover. The weak links may thus keep species from driving one another to extinction.

Mathematical models have also revealed that food webs may be unstable，where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s，scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species---including species they did not directly attack.

And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean，we fished for top predators such as cod on an industrial scale，while on land，we killed off large predators such as wolves. These actions have greatly affected the ecological balance.

Scientists have built an early-warning system based on mathematical models. Ideally，the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key，which scientists says because once ecosystems pass their tipping point(临界点)，it is remarkably difficult for them to return.

1.What have scientists discovered with the help of mathematical models of food webs？

A.The living habits of species in food webs.

B.The rules governing food webs of the ecosystems.

C.The approaches to studying the species in the ecosystems.

D.The differences between weak and strong links in food webs.

2.A strong link is found between two species when a predator______

A.has a wide food choice B.can easily find new prey

C.sticks to one prey species D.can quickly move to another place

3.What conclusion can be drawn from the examples in Paragraph 4？

A.Uncontrolled human activities greatly upset ecosystems.

B.Rapid economic development threatens animal habitats.

C.Species of commercial value dominate other species.

D.Industrial activities help keep food webs stable.

4.How does an early-warning system help us maintain the ecological balance？

A.By getting illegal practices under control.

B.By stopping us from killing large predators.

C.By bringing the broken-down ecosystems back to normal.

D.By signaling the urgent need for taking preventive action.
