At his studio in Beijing, artist Zhang Xiaodong piles hundreds of sheets of thin top of one another until they form a complete image. When there is a slight air, the pages flow, giving life to the book     1     (it).This dragon scale bookbinding(装订),     2    (stretch)back more than 1,000 years to the Tang dynasty.

With few of the books     3     (survive)to the present day, the bookbinding technique was     4     the risk of disappearing before Zhang decided to research and bring it back to life. After half a year’s study, he finally learned     5     the ancient bookbinding worked.     6     (source)materials traditionally used in bookbinding Zhang also visited old towns and heritage (遗址)sites. Then came the     7     (crucial)-and difficult-part of the binding process: controlling the placement of each page. In order to create a complete picture, each sheet needs to be placed in     8     (exact)the right place. Zhang said that an error of just     9     hundredth of a centimeter can produce a huge, visible error when a book’s hundreds of pages are displayed together.

Zhang’s     10     (prepare)that went into producing this particular work shows the very modern way that the artist tries to understand the subject matter.

2 . 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式。

A new study shows that     1     two countries with the world’s     2     (large) populations are leading the increase in greening on land. The effect comes     3     (main) from ambitious tree     4     (plant) programs in China and agriculture in both countries.

China alone accounts     5     25% of the global increase in leaf area with only 6.6% of global vegetated (有植物的) area. The greening in China is from forests (42%) and croplands (32%).

China’s outsized     6     (contribute) comes in large part from programs intended           7     (protect) and expand forests, in an effort to reduce the effects of soil erosion (侵蚀), air pollution and climate change.

Taken all together, the greening of the planet represents an increase in leaf area of plants and trees equal to the area     8     is covered by all the Amazon rainforests.

Land area     9     (use) to grow crops is comparable in China and India and     10     (change) very little since the early 2000s. Yet the countries have greatly increased both their annual total green leaf area and their food production.

3 . There’s fresh evidence that eating a healthy diet, one that includes plenty of fruits and vegetables and limits highly processed foods, can help reduce symptoms of depression.

A randomized controlled trial published in the journal PLOS ONE finds that symptoms of depression dropped significantly among a group of young adults after they followed a Mediterranean-style pattern of eating for three weeks. Participants saw their depression “score” fall from the “moderate” range down to the “normal” range.       1     Alternatively, the depression scores didn’t change for those who didn’t change their diet.

These participants continued to eat a diet higher in refined carbohydrates, processed foods and sugary foods and drinks. Their depression scores remained in the “moderate” range.       2    

There is a highly consistent evidence base linking healthier diets to reduced depression risk. For example, a 2013 analysis of 22 previously published studies showed that the Mediterranean diet was associated with a lower risk of depression.     3     It suggested that a diet rich in fruit, whole grains, vegetables, fish, olive oil and low-fat milk was associated with a lower risk of depression while a diet rich in greater amounts of red meat, refined grains, sweets and high-fat dairy products was linked to a higher risk of depression.

    4     They could be education, income, body weight and other health behaviors. Most of these studies show an association and “can’t indicate cause and effect”. In other words, the studies don’t prove dietary changes directly cause the improvement or decline in mood.     5     it is unlikely to be a cure for all mental diseases.

A．A 2017 study had similar findings.

B．People are quite surprised by the findings.

C．And they reported lower levels of anxiety and stress too.

D．Because it is hard to assess participants’ mental health,

E．So, while diet may be important to your mood and mental health.

F．We need further research to understand how our brain works to stay healthy.

G．Actually, these links between diet and depression are independent of some relative aspects.

4 . A few years ago, Paul Allen, the co-founder of Microsoft, published the results of something called the Great Elephant Census, which counted all the savanna elephants in Africa. What it found rocked the conservation world: In the seven years between 2007 and 2014, Africa’s savanna elephant population decreased by about a third and was on track to disappear completely from some African countries in as few as 10 years.

To change that trend, researchers landed on a technology that is rewriting the rules for everything from our daily appliances to our cars: artificial intelligence. “AI can process huge amounts of information to tell us where the elephants are, how many there are,” said Cornell University researcher Peter Wrege. “And possibly tell us what they are doing.”

There are two kinds of elephants in Africa: savanna elephants, which were counted by Allen’s census, and forest elephants, which the census couldn’t account for because that elephant lives in thick rainforest. In the forest, Wrege says, losing a forest elephant is easy to do. “Sometimes you see them, let’s say, 15 meters away from you and then they move 5 meters into the forest and you can’t see them,” he said. “Somehow they just disappear.”

Wrege’s use of artificial intelligence in the rainforest has been less remarkable, but no less important. The networks on which his forest elephant count depends are still training, so he doesn’t have a precise forest elephant count yet. He has found that trying to count forest elephants depends on various factors. But the AI has uncovered some unexpected things. For example, it appears that elephants don’t go to some parts of the forest during specific times of the year. That’s important to know because it can inform the way conservation park managers position their forces. “You can say,” Wrege said. “OK, we know that elephants are not using this huge part of this park for these seven months. No poachers are going to find an elephant anyway. So we don’t need to send any anti-poaching teams there.”

5 . The simple word “fun” only has one syllable（音节）, so you'd think you'd add “er” or “est” on it to create comparatives or superlatives. But if you were to say “I think Magic Kingdom is a funner park than Epcot.” or “Fantasy World was the funnest vacation ever!” , you might get some strange looks. It sounds like something cute-because-it's-wrong that a little kid would say. You might begin to doubt the existence of such a word as “funner”. But. . . why? “Fun” has one syllable. So why do we choose to use “more fun” as the comparative—especially considering that the similar word “funny”, which has more syllables than “fun”, uses the suffixes（后缀）with no problem?

Well, the confusion comes from the fact that the word “fun” was not originally an adjective（形容词）. Until the early 19th century, it was mostly just a noun, and it gained its meaning as “amusement” in the 18th century. But as early as the 1800s, people began using it as an adjective, the way we'd describe “a fun time” or “a fun place” today.

And, as they usually do when people use words wrong, grammar experts blamed this usage, one professor saying that hearing the adjective version of “fun” caused severe sickness" in him. But obviously, that didn't stop people from using “fun” as an adjective, which brought up the question of its comparative and superlative forms.

Grammarians have mostly come around to the use of “fun” as an adjective though some dictionaries still call it informal, but the comparative and superlative forms are a bit more wishy-washy. There was and remains a mentality of “Fine, you can use ‘fun’ as an adjective. . . but, like, it's not a real one, so it can't follow the rules of real adjectives”. Most dictionaries agree that the answer to “is funner a word?” is yes. But this doesn't mean that "more fun" and "most fun" are incorrect. In fact, in formal writing, you'll probably still want to use those instead of “funner” and “funnest”.

B．By exploring the answer to a question.

C．By providing evidence for an argument.

2. What happened to the word “fun” in the early 19th century?

A．It began to be used as an adjective.

B．It was taken in by dictionaries.

C．It gets the meaning”amusement”.

D．It appeared in formal writing.

3. What was grammarians' attitude towards using “fun”as an adjective?

A．They tried to stop people using it.

B．They were unwilling to accept it.

C．They were confused as to what to do.

D．They blamed each other for the mistake.

4. What's the best title for the text?

A．Is Funner a Word?	B．Are Grammarians Correct?
C．Can All Rules be Followed?	D．Will the Confusion Continue?

6 . Given the crowds of visitors and many attractions at the Disney parks, it's easy to get lost. Thankfully, you will always find a worker to point you in the right direction. When you do, you just might start to notice something unique about their body language—and it's just one of the many secrets Disney employees won't tell you.

Cast members, as park employees are called, are taught in their training to always point with two fingers instead of one. The first reason for this is that pointing with just the one index finger(食指), as most Americans do, is considered impolite in some cultures and countries. The Disney parks have always attracted many international visitors, so the friendlier two-finger gesture became the norm among employees, in an effort to be sensitive and welcoming to every person. Employees have even affectionately named it "the Disney point”. Michaela Paris, a former Disney employee, said the Disney point is a sign of respect.

"Disney receives plenty of foreign travelers to their parks. The typical single finger point is a symbol of disrespect and has a negative(负面的) meaning in many cultures. Therefore, Disney created 'the Disney point' to accommodate all of their guests, " Paris said.

Other sources say this way of pointing is related to Disney himself. According to the Huffington Post, it's actually how Walt Disney himself used to point things out to visitors, because he usually had a cigarette balanced between the two fingers. You won't find cast members today smoking a cigarette—there's no smoking allowed for anyone, employees or guests, once you are inside the entrances at Disney parks—but the tradition of pointing with two fingers still stands.

Keep an eye out for the statue of Walt and Mickey doing "the Disney point" next time you're at Disney World. Meanwhile don't miss other such rules that all Disney employees must follow.

1. When will a visitor probably notice "the Disney point"?

A．When asking the way.	B．When entering the park.
C．When greeting foreigners.	D．When smoking a cigarette.

2. What does “the Disney point” refer to?

B．An employee.

C．A park.

D．A statue.

3. What does the underlined word "accommodate" in paragraph 3 mean?

A．offer space to.

B．put up.

C．provide food for.

D．adapt to.

4. What is paragraph 4 mainly about?

A．Rules to follow in the park.

B．The life story of Walt Disney.

C．Some attractions at Disney World.

D．A possible origin of “the Disney point”.
