Food can be a great cause. And just like people,animals often get quite creative when they’ re in the mood for a meal or treat. Now a video shows Asian elephants cleverly blow air to move food.
Kaori Mizuno and colleagues worked with two female Asian elephants,Mineko and Suzuko. The two elephants lived in an area surrounded by a U-shaped ditch(壕沟) .The ditch was just shallow enough that an elephant could reach an object on the bottom with its trunk(象鼻) .But it couldn’t reach an object on the far side of this ditch. This let Mizuno’s team set up a difficulty for the animals. They xegularly set out tasty treats,apples,bamboo,potatoes or fallen leaves on the far side of the ditch. Both elephants were caught on film blowing their trunks to draw the food. Each would reach out her trunk,aim backwards a bit and then blow out a few puffs of air. That drove the food so that it was close enough to catch. Mineko used fewer puffs,blew longer and aimed better than Suzuko.
Scientists once believed that only humans used tools. It's worth looking at the elephants’ behavior again. Is trunk-blowing considered tool use? The classic definition of a tool is “the external (外部的) employment of an unattached environmental object.w Air is not an “object ,” So it may not qualify. But what may be more important to consider is the thinking processes that drive the behavior.
The researchers are unsure how the elephants picked up this trunk-blowing behavior. They might have done it by accident. But the fact that two females living together are both showing the same behavior suggests that one elephant may have copied it. And let’s hope so. After all,elephant trunk-blowing might be entertaining.
9. What has Kaori Mizuno5 s team found out?
A. Elephants eat too much.
B. Elephants can bring food closer.
C. Elephants are popular with people.
D. Elephants are brave to do dangerous things.
10. What was the function of the ditch in the experiment?
A. Toserveasachallenge.
B. To protect the elephants.
C. To make the elephants excited.

C. shows elephants are important animals
D. suggests attention be paid to the drive of trunk-blowing
12. The underlined word “so” in the last paragraph refers to.

Over the past decade,there have been many scientific studies on the digital (数字的) activity of people,such as making mobile calls,texting,e-mailing,and posting on social media. Nearly all human behavior leaves a digital footprint. Therefore,scientists can use such digital activity as a way to track human activity. For example,they can study differences between cultures in sleep patterns,work schedules,and spare time activities.
Researchers from Finland and Denmark use a completely new approach to study digital rhythms (规律) .Previous studies focused on general patterns across large numbers of people. However,this time researchers focus. on pronounced,long-term differences in rhythm between inid?viduals. They show that people tend to have their personal rhythm of digital activity. It is stable like a personal signature 。(签名)
“Each individual follows their own daily rhythm ,” says Talayeh,who led the research. “In almost every case,the patterns differ strongly from the average behavior,for example by increased calling frequency during mornings,mid-days,or evenings ,” says Talayeh. What drives these individual differences is not yet clear. Geographical and cultural differences clearly play a role. “There could also be an effect of (生理学) .We see this research as the first step to understand how activity patterns are related to other people's characteristics,such as personality and mobility behavior,” say Talayeh.
This finding could also have medical use. Digital rhythms could be monitored for patients with mental health problems. Sudden changes in patients’digital rhythms could be a sign that treatment may be necessary. “Combining this research with Big Data may also bring new ways of research in sleep studies ,” concludes Talayeh.
9. What do scientists use the digital activity of people to do?
A. To make their research easier.
B. To know about people's behavior.
C. To aid the development of social media.
D. To reduce people's dependence on mobile phones.
10. Which of the following can best describe digital rhythms?
A. Natural but casual.
B. Personal and fixed.
C. Different but unclear.
D. Changeable and mysterious.
11. According to Talayeh,digital rhythms .
A. have nothing to do with personality
B. have a great effect on everyday habits
C. may have something to do with culture
D. can help ?ie development of physiology
12. What is the use of digital rhythms in the medical field?
A. They can help avoid patients’ sleep problems.
B. They will change the ways doctors do their work,
C. They could free people of mental problems.
D. They may tell whether a patient is well.

Kit-ken Lim,a student from Taiwan,China,is studying in Chicago. The following excerpts (摘录) are taken from her diary during her first three months in the United States.
August 31
People often refer to Taipei as “The Sleepless City^, but I didn't understand why until I got to . Chicago. I was shopping wkh another student this evening when suddenly the store owners along the street started pulling down their gates and locking their doors,even though it was still light out. This is something I’ve never seen in Taiwan,where the busiest streets “stay awake” all night. You can go out to restaurants,stores,and movies even long after midnight.
September 5
After the first week of class,I’ve found some differences between Chinese students and American students. Whenever a teacher asks a question,my classmates give their answers almost immediately. And some of them interrupt the teacher. In Taipei,we’ re usually quiet in class so the teacher can finish on time. We tend to ask the teacher questions afterward. I don’t know whether it's acceptable here for students to ask teachers questions after class. October 6
I met a really interesting local girl in my neighborhood café. I was writing a letter to my mother,and she asked me what language I was writing in. We ended up talking for about an hour!People in Chicago seem very comfortable with each other. It seems quite natural for two people to just start talking in a café. This is something that doesn’t happen in Taipei. At home,I would never just start chatting with a stranger. I like that because it's easy to meet new people here.

Americans gone super!Super-sized,that is. New Yorker Morgan Spurlock tells the truth about what is really in food and how much fat Americans gain in the new documentary,iSwperszze Me!In America around 75 million people are overweight.
Morgan Spurlock put the issue of obesity to a test: eating nothing but McDonald's for an entire month. He faced many effects. For example,after the first week,his body fat increased by 5%. After the entire month,he gained 24. 5 pounds. His cholesterol (胆固醇) increased 65 points. He got frequent chest pain,nausea (恶心)depression,headaches,etc. He nearly doubled his risk of heart disease.
During his experiment,he traveled the country to find out what we,re really eating. He met a man who had eaten 19 ,000 big hamburgers from McDonald,s. He discovered that children knew more about Ronald McDonald than George Washington or Jesus. He tried over ten times to schedule an interview with the head of McDonald's,but didn’t get a reply.
In the end,I found myself disappointed with the documentary. It wasn 51 the lack of information. In fact,if this was based on information,I’d give it 5 stars. Spurlock didn't let the information speak for itself. If he had,this documentary would have been brilliant. His points were overstated.
He ended the documentary by saying, “Who do you want to see go first? You? Or them?” I believ? the point he’s trying to make is that eating fast foods will endanger US. But it’ 11 take a lot more than a ：hamburger once a month to kill US. Yes,if you eat McDonald's every day,you need to change your :eating habits. But scaring the rest of US into eating i vegan pies every day? No,thank you. r II take my coke super-sized.

C ★★★★☆
For adults,memories tend to lose with time. But there are conditions under which the opposite is true for small children.
While playing a video game that asked them to remember relations between objects,4-and 5-year-olds who replayed the game after two days scored more than 20 percent higher than kids who replayed it later the same day. “An idea is that kids can be smarter than we thought they could be,” said Kevin Darby,co-author of the study. “They just need more time."
The findings give ?s. a window into understanding memory. First,we showed that if children are given pieces of similar information in a close "we 5/7训(时间跨度) ，there is almost a complete loss of memory. Second,we showed that introducing delays prevents that loss. It seems surprising that children can almost completely forget what they have just learned,and that their memories can actually improve with time.
We know from previous research that kids struggle to form difficult connections in the moment,so we thought that with some time off and periods of sleep they might be able to do better. And it turned out that when they had time to remember the information,they did better.
Researcher Slo?tsky said that the study does not in any way suggest that kids can absorb (吸收)adult-sized quantities of information if only they are given time to sleep on it. Rather,it means that they can remember kid-sized quantities of information in given time,even if they seem forgetful in the moment. “We’ve shown that it's possible for children's memories to improve with time,but it's not like we’ ve discovered a method for super-charging how much they can remember,” he said.
9. What can we learn from Kevin Darby’s words?
A. Children are good at learning things.
B. Children can remember better than thought.
C. Children are better at remembering than adults.
D. Children can learn better through computer games.
10. The third paragraph is mainly about.
A. the meaning of the study
B. the problems with the study
C. the background of the study
D. the process of the study
11. The purpose of what Sloutsky said is .
A. to provide an example for the study
B. to stress the importance of the study
C. to avoid misunderstanding the study
D. to remind people to put the study into practice
12. What might be the best title for the text?
A. The power of memory
B. The best way to learn
C. Delayed remembering
D. Free kids from pressure

Adding math talk to story time at home is a winning method for children's math achievement. A study by psychologists (心理学家) showed a marked increase in math achievement among children whose families used Bedtime Math,an iPad app that provides math problems for parents and children to solve together. The app’ s effect was especially strong for children whose parents are anxious or uncomfortable about math.
Previous research from this group showed the importance of adults’ attitudes about math to children's math success. The new findings proved that highly organized,positive 似(交流) around math at home could cut the link between parents’ uneasiness about math and children's low math achievement. ”Many Americans experience high levels of anxiety when they have to solve a math problem,with most adults feeling worried at least about math/' said Beilock,author of a book about stress and performance. aThese math-anxious parents are probably less likely to talk about math at home,which affects their children's ability in math."
The study stressed the importance of learning math outside of the classroom. "For many families,reading stories is a regular part of a child's daily life.But when it comes to math,parents widely believe that it is the responsibility of schools,and they pay less attention to their children^ math learning at home,” said Levine,professor of Education and Society in Psychology. uWe found brief,high-quality parent-child interactions using Bedtime Math increased children's math learning during the first grade."
The app was especially beneficial for children of very math-anxious parents,whose gains in math achievement over the course of the school year were huge when they used the math app. Even infrequent use of the math app — once a week — improved children's math performance.
9. The app is most suitable for children.
A. who are good at math
B. whose parents are poor in math
C. who are ready to study math in college
D. whose parents spend little time with them
10. What do parents think of math in general?
A. It depends on school education.
B. It should be learned by oneself.
C. It should be highly valued at home.
D. It is less important than other subjects.
11. What suggestion can parents get from the text on math learning?
A. They should be honest about their math.
B. They should learn from children carefully.
C. They should respect children's learning habits.
D. They should discuss math with their children actively.
12. The author writes the text mainly to.
A. advertise an app Bedtime Math
B. show different ways to learn math
C. stress the importance of story time
D. explore the best time for learning math .

Angle of perception
Once,a professor put a chair at a certain distance on the stage,and then started his lecture. Pointing to the middle row audience,those who were sitting exactly in front of the chair,he asked, “How many legs does the chair have? Please tell me exactly what you observe,not assuming that the chair has four legs."
The first person from the middle row replied, “Two”，because ihe other two legs were hidden behind the front legs. The professor then asked the same question to the viewers on the left. The answer came “Three”. Here,one back leg was hidden behind one of its front legs. So,only three could be seen. The same question was repeated to those on the right and the extreme comers of the audience. The answers he received were uThree^ and aF〇?ur,? respectively (分别地) .
The professor then said, “Look!All of you know that the chair has four legs,but when I asked you to answer me exactly what you observed from your angle (角度) ，your answers were different. But do you think it is possible? Do you think that the same chair has two,three or four legs? Obviously the answer is “no”. We assumed it as the different numbers* according to our perception,the angle. from which we view. So what I mean is that our perception is not always correct or true. The same thing happens to everybody when he / she judges others from his / her view point. Kindly,think about this when you are judging others." Sometimes,things are misunderstood because of our angle of percep-tion.
Find the words in the text that fit the following descriptions.
1. V. to think or accept that sth is true but without having proof of it (in Paragraph 1)
2. n. an idea,a belief or an image you have as a result of how you see or understand sth (in Paragraph 3)
