3 . In recent years, researchers of Cornell University’s Food and Brand Lab are studying how environmental factors influence many Americans to unnoticeably eat too much. Many people wrongly believe that factors like hunger or boredom and depression are the main causes of overeating, but their research has shown otherwise. It is thought that we overeat if the food is good or if we’re really hungry. In reality, those are two of the last things that determine how much we eat.

In one experiment, the researcher placed jars of candies in workers’ offices for a month. Then, he moved the candies 1.8 m away. The office workers ate five more candies each day when the jar was closer to them, equaling an additional 125 calories a day. It does not sound too bad, but add that up over a year and you will have gained 5.4 kg. “If something is visible, every time we see it, we have to make a decision: to eat it or not?” the researcher explained.

In the other experiment, moviegoers were given five-day-old popcorn, some in medium-size buckets, some in large buckets. The researcher found that moviegoers who had the larger buckets ate 53 percent more, despite its unpleasant taste. He believes that the distraction of the movie and hearing others eat the popcorn persuade people to keep eating.

The findings in other researches have shown that we tend to eat more when we use larger dishes, eat in front of the television, or dine with someone who eats a lot. Researchers of the lab advise a gradual approach in changing eating habits. People can cut a couple of hundred calories a day by doing things such as avoiding open food dishes at the office, using smaller serving bowls, sitting next to the slowest eater and being the last one to start eating.

4 . A teacher gave his students a test. Most of the students finished all the questions without much effort _______they all read the last one which was “What is the first name of the woman who _______ the school? ”

All of the students thought that this question was some kind of _______. They had all seen the cleaning woman many times during each day at school. It was _______ that she was tall and old, but how would they know her _______?

So they all _______ their test paper, leaving the last question _______. Just before the class ended, one of the students asked if the last question would count toward the results of the _______.

“_______”said the teacher.

He went on to say, “In your lives and careers, you will ________ many people and they are ________individual, so they each are worth your ________ and care, even if all you do is ________and say “Hello”.

Over the following days each of the students ________ the importance of finding out the name of the cleaner and introduced themselves. They all learned that cleaner’s name was Dorothy and they never forgot the ________ that everyone is important.

6 . In his 1975 novel Changing Places, British novelist David Lodge described the lifestyle of two literature professors who cross the planet repeatedly, trading a rainy English campus for a sunny California university, and vice versa. Along the way, many other things are exchanged as well, including affairs of the heart.

While scholars working today don't enjoy the same benefits—luxury hotels and business-class flights in particular—they might recognize that they still live in Lodge's small world. Since the mid-l970s, transportation and communication advances have made the planet steadily smaller and the number of international students has risen sharply in turn. In Lodge's novels, universities seemed changeless, white four decades later they are fully engaged in internationalization.

In the post Cold War era, academic relationships are becoming richer and more complex. Students in the Global South, eager to participate in the knowledge economy and receive some of its benefits, are driving much of the increased demand for education at all levels.That future profits and solutions to pressing global problems are to be found in advanced research makes international cooperation essential.

As a recent report shows, internationalization is a strategic priority for many universities and they're working to put themselves on the world map.When competing for new lands, however, familiar rules no longer apply and new guidelines must be established to increase the chance of profits, or at least minimize potential losses.

The internationalization of universities raises an old problem: the ability to connect to global development without losing diversity. Some aspects of global science, such as Nobel prizes, tend to promote a “winner-takes-all' system. Higher education institutions should take a critical distance from this tendency and embrace their diversity— there is more than one Treasure Island for science. Internationalization is not about going to places similar to our own country or institution. Instead, students and scholars can find stimulating environments and academic conditions that can challenge what they take for granted.

We generally assume that higher education and innovation go hand in hand, but we do not know how innovation comes about. The only reasonable assumption is that it happens in difficult conditions, when we have to overcome a problem. That's why it's important to put students and scholars in challenging diverse situations and help them learn different ways of thinking. From my point of view, enhancing access and promoting diversity should be the compass of all internationalization strategies. So, the ship has started, and let's sail.

7 . I'm an early user of social media. For the most part, I've enjoyed the time I've spent on the site. But like many friends I know, I was also starting to feel like my visits to Facebook were just a waste of time.

Of course, the obvious move would just be to steer clear of Facebook and other social media sites. But as a writer, I have to use social media several times a day. And once I'm in the site, it's almost impossible to take no notice of those notices reminding me of posts in my personal feed（信息推送）. I felt like I had to find the one or two meaningful posts that made my social media feed worth the time.

Then I came across a post by Melissa Hartwig, the founder of the Whole30 program. In the post she said "Don't act like social media just happens to you; make it work FOR YOU."

It hit home with me. I immediately set out to change the way I was using social media. I hid and unfollowed groups and accounts（账户）that were not adding something active to my life. I didn't stop to think. I just clicked my way through the feed.

I'm not burying my head in the sand. I continue to follow people whose opinions on different topics differ from my own, but their words are interesting and open-minded.

Then I limited my interaction（互动）on social media. Unless I had something to say, I no longer interacted. A study found that inactive use of social media has a bad effect on our mood, while active use—sharing thoughts and commenting on others' posts—improved mood.

The result? I can say without doubt that I no longer worry about getting into a time-wasting vacuum（真空）. That's because my feed is nowhere near as bottomless as it once was.

9 . Madison stared through the window and watched a puffy white cloud pass over the woods across from the school. It must be wonderful to be a bird, she thought. Total freedom. No math class to sit in, and her days would be spent on horseback. She thought of her horse, Star.

“Madison. Could you please join us again?” Mrs. Smith said. “I was just asking the class if anyone had any problems with the homework assignment.”

“Well, I didn’t have any problems doing it, but I had problems remembering to put it in my school bag after I did it.” Some giggling spread through the room.

“Madison. I don’t know what I am going to do with you. You’re such a smart girl but you just don’t apply yourself. Class, clear your desks. Our guest is here and welcome Doctor Landon. He is a veterinarian (兽医). He came here today as part of our continued Career Explorations Program.”

Madison tried to focus as Doctor Landon talked about how important grades were and how he struggled with math when he was a kid. Doctor Landon was still talking but she lost track of what he was saying. Then a word caught her attention. Horse. Was he talking about horses?

Gradually, Madison knew Doctor Landon had come to her town and house when her horse, Star, needed care. She liked it that he even knew her horse’s name. “So, you just travel around and take care of horses all day long?”

Doctor Landon nodded. “I travel with my truck to take care of horses and ponies across the county. It is a lot of work, but I love it.”

Madison’s mouth fell open. What a life that must be, she thought. At that moment, sitting in class, Madison could see her future and her life suddenly seemed bigger. By the time she got off the bus that afternoon, her plans for the afternoon had changed. She was still going to ride Star, but first she was going to spend an hour studying math. Then tomorrow she’d spend an hour studying science.

10 . If you struggle to fall asleep quickly, you’re not alone! Fortunately, there are plenty of solutions you can try. With a few changes, you can fall asleep fast every night!

Keep your room dark. Turn off all the lights above your head when you go to bed. Any bright light can make you believe it is too early in the day for sleep. If you want to read or write before bed, try using a small book light. Now that blue lights can keep you awake, red ones are a great choice.

If you can, keep noise in and around your room the lowest at night. If you have an old clock that ticks loudly and keeps you awake, replace it with a silent one. If you share your home with anyone else, request that they keep noises like talking, music, or TV shows at the lowest while you are trying to sleep. It is difficult to fall asleep if you live near a busy road or hear other boring sounds after bedtime. You could get a white noise machine or play recordings of nature sounds, like waves or whales’ singing. You could also listen to soft, relaxing music.

Read a book in bed if you have difficulty in falling asleep. Staying in bed doing nothing when you’re having trouble falling asleep may keep you wide awake. While reading in bed may be slightly harmful to your eyes, it can distract (分散) you from your thoughts and help you feel sleepy. But remember to read from a print book rather than something with a screen. The light from electronic screens can keep you awake.

Lowering your body temperature helps you sleep, so set the room temperature between 15.5℃-21℃ could do the trick.
