Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible(無可抗拒的)? For one thing, it’s everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking.

Make friends with dainty(講究的) eaters.

Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in.

See happy movies and always get the smaller bag of popcorn(爆米花).

According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container.

Eat breakfast.

Nutritionists have gone back and forth（來來回回）about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising.

Divide your food and conquer overeating.

Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you’re eating and of portion size. Researchers advise reallocating（再分配）snack foods into small plastic bags. It sounds simplistic, but it works.

1.Why do people eat too much junk food though it is bad for our health?

A. It’s delicious from chips to candy.

B. Because it’s available here and there.

C. It’s easily taken everywhere.

D. It’s easily bought in fast food restaurants.

2.Which of the following is TRUE according to the passage?

A. If people are watching a tragedy, they eat up to 29% more popcorn.

B. People are likely to eat more food when staying with friends.

C. Nutritionists have the same opinion about how much to eat in the morning.

D. People prefer to snack from a large bucket.

3.What will he or she do if he or she wants to lose weight?

A. To eat nothing in the morning.

B. To get up early and to go to bed late.

C. To eat breakfast and exercise.

D. To snack from a medium-size bucket.

People do not analyze（分析） every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However , when all these methods fail, the person with a problem has to start analyzing. There are six stages in solving a problem.

First the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must see that there is a problem with his bicycle.

Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears（齒輪） ,the brakes, or the frame. He must make his problem more specific.

Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decides that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully. After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gearwheels and replace the old ones; tighten or loosen the gear wheels.

Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gearwheels. He immediately realizes the solution to his problem: he must clean the gear wheels.

Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short, he has solved the problem.

1.What is the best title for this passage?

A. Six Stages for Repairing Sam’s Bicycle

B. Possible Ways to Problem-solving

C. Necessities of Problem Analysis

D. Suggestions for Analyzing a Problem

2.In analyzing a problem we should do all the following except __________.

A. recognize and define the problem

B. look for information to make the problem clearer

C. have suggestions for a possible solution

D. find a solution by trial or mistake

3.By referring to Sam’s broken bicycle, the author intends to _________.

A. illustrate the ways to repair his bicycle

B. discuss the problems of his bicycle

C. tell us how to solve a problem

D. show us how to analyze a problem

4.Which of the following is NOT true?

A. People do not analyze the problem they meet.

B. People often accept the opinions or ideas of other people.

C. People may learn from their past experience.

D. People can not solve some problems they meet.

My transportation was unexpectedly smooth and I arrived at the meeting half an hour earlier. I kept my eyes on the restaurant door. Several customers entered, but not my friend. At 6:00 pm, she sent me a text message: “Urgent work to finish. Will be 20 minutes late.”

I had left my book in the office, so I spent the time thinking of my experiences of being late in China. On my first visit in 1985, punctuality was deeply rooted in the Chinese hearts. There were no traffic jams then.

As a teacher in Canada, I always insisted on punctuality. I would open the classroom door to a late student for the first time and the second, but not the third. During the six years I worked for CCTV, I had a Chinese friend whom I often saw at lunch time, or after work. We used to meet at the subway station nearby. He was always late by 10-20 minutes. To my question, “You were busy?” he would surprisingly answer, “ No.” Once I asked him to check the clock in his office, he smiled.

In March 2015, I got permanent residence (居住權(quán)) in China. The ceremony was scheduled for 9:00 am at the Public Security Bureau on the Second Ring Road. I told my driver I had to get there by 8:40 am. “No problem,” he replied. But he thought he had time to drop someone off at the airport before picking me up. I desperately waited for him. Then, to rub salt into my wound, he had to stop at the exit of a gas station. Finally, I entered the room at 9:07 am ── the last guest to arrive!

1.What can we learn from the passage?

A. The author is always late for work or any activities.

B. The author dislikes making friends with unpunctual persons.

C. The author hates being late from the bottom of heart.

D. The author can do something to deal with unpunctuality.

2.If the author’s student comes late for the third time, _______.

A. he will let him/her remain outside

B. he will open the door for him/her again

C. he will shout at him/her loudly

D. he will tell him/her to take care next time

3.How did the Chinese friend feel when the author asked him to check the clock?

A. Excited. B. Embarrassed.

C. Satisfied. D. Shocked.

4.Why didn’t the author arrive at the ceremony on time?

A. Because the gas was running out.

B. Because his driver met a guest at the airport.

C. Because there was a big traffic jam on the road.

D. Because the driver estimated the time wrongly.

Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.

Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.

Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I’m dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

The great 19th century explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”

1.Which of the following will Kristina Wegscheider agree with?

A. Traveling alone is a necessary experience for everyone.

B. It is more meaningful to travel in foreign countries.

C. It is comfortable to travel around without a friend.

D. Traveling abroad helps people to find new things.

2.Traveling alone is challenging because ________.

A. you have to make things on your own

B. it is hard for you to prove yourself to others

C. you can only depend on yourself whatever happens

D. it will finally build your character

3.What can we infer about Chris Richardson?

A. He started traveling alone at an early age.

B. He was once shot in the arm.

C. He used to work as a salesman.

D. His website inspires others a lot.

4.What is the best title for the passage?

A. Travel Abroad B. Travel Alone

C. Travel Light D. Travel Wide and Far
