How often do you travel by plane?

How much electricity do you use? These days everyone is worried about the size of their carbon footprint. In order to reduce global warming we need to make our carbon footprints smaller. But how much CO₂ are we responsible for?

A new book by Mike Berners Lee (a leading expert in carbon footprint) might be able to help. How Bad are Bananas? The Carbon Footprint of Everything looks at the different things we do and buy, and calculates the amount of CO₂ all of the following created: the ingredients, the electricity used in the brewery, the equipment, the travel and commuting of the beer, and the packaging. It’s amazing how many different things need to be included in each calculation. And it’s frightening how much carbon dioxide everything produces.

But all of this can help us decide which beer to drink. From Berners-Lee’s calculations, it’s clear that a pint (568ml) of locally-brewed beer has a smaller carbon footprint than a bottle of imported beer. This is because the imported beer has been transported from far away, and it uses more packaging. The local beer only produces 300g of CO₂, but the imported beer produces 900g! So, one pint of local beer is better for the environment than three cans of cheap foreign lager from the supermarket.

Berners-Lee has even calculated the carbon footprint of cycling to work. Nothing is more environmentally-friendly than riding a bike, surely? Well, it depends on what you’ve had to eat before. To ride a bike we need energy and for energy we need food. So if we eat a banana and then ride a kilometer and a half, our footprint is 65g of CO₂. However, if we eat bacon before the bike ride, it’s 200g. In fact, bananas are good in general because they don’t need packaging, they can be transported by boat and they grow in natural sunlight.

So, does this mean that cycling is bad for the environment? Absolutely not, for a start, if you cycle, you don’t use your car, and the fewer cars on the road, the fewer traffic jams. And cars in traffic jams produce three times more CO₂ than cars traveling at speed. Cycling also makes you healthy and less likely to go to a hospital. And hospitals have very big carbon footprints!

So maybe it’s time for us all to start making some changes. Pass me a banana and a pint of local beer, please.

66. According to Berners-Lee, which of the following produces the most carbon dioxide？

A. A pint of local beer we drink.

B. A pint of imported beer we drink.

C. A banana we eat before a bike ride.

D. The bacon we eat before a bike ride.

67. Why are bananas good in general?

A. They grow naturally.

B. They produces less CO₂.

C. They don’t need packaging.

D. They provide energy for cycling.

68. The underlined word “brewery” in Paragraph 3 most probably means “___________”.

A. a factory where beer is made

B. a machine which makes beer

C. a container where beer is stored

D. one of the things from which beer is made

69. To make our carbon footprints smaller, we should often ___________.

A. cycle to work

B. drink more local beer

C. calculate the amount of CO₂

D. buy cheap things from the supermarkets

70. What’s the most suitable title for the passage?

A newly-published study has shown that loneliness can spread from one person to another, like a disease.

Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 individuals are taking part.

Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.

University of Chicago psychologist John Cacioppo led the recent study. He and other researchers attempted to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.

Having a social connection with a lonely person increased the chances that another individual would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone’s loneliness.

The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.

The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.

Loneliness has been linked to health problems like depression and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.

The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.

What is true about the Framingham Study?

A. It was only conducted in 1948. B. It involves more than 12,000 participants.

C. It was led by John Cacioppo D. It showed that any behavior could spread.

From the passage, we can learn that .

A. the habit of littering doesn’t spread

B. a lonely person won’t have friends

C. everyone may be affected by others’ loneliness

D. lonely people don’t know the cause of their loneliness

Which statement about the spread of loneliness is true?

A. The spreading effect was the second strongest among friends.

B. No spreading effect was found on husbands and wives.

C. Women are more likely to be affected than men.

D. Brothers are more easily affected than neighbors.

If you make 10 more friends in a year, the days of your feeling loneliness will be reduced by .

A. 48 days B. 25 days C. 20 days D. 15 days

What is the main idea of the passage?

A. Actions should be taken to help lonely people. B. People feel lonely for many reasons.

C. Ways to fight against loneliness. D. Lonely people can affect others.

Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing.

By putting thoughts into words, you are telling yourself the logic (逻辑) behind what you think, feel, or only partly understand. Often, explaining a thought is the process of understanding. In other words, you increase your brain power by exercising your “explain power.”

Try this experiment. Explain how you’ll increase your brain power, even if you have no idea how right now. Just start with anything, and create an explanation. For example, start with “I’ll learn chess,” or “I’ll read an article on the mind every week.” Explain how that will help. You’ll be surprised how often this becomes a workable plan, and if you actually do this, you’ll have a better understanding of your brain twenty minutes from now.

Another benefit of writing is that it helps you remember. Many, if not most, highly productive people are always taking notes. You can try keeping it all in your head, but if you keep a journal of your ideas the next time you’re working on a big project, you’ll probably have more success.

Want to understand a topic? Write a book about it. That’s an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better. Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you’re half-way there.

Writers don’t always write because they clearly understand something beforehand. Often, they write about something because they want to understand it. You can do the same. Writing will help bring you to an understanding. Give it a try.

Sixteen years ago I learned this lesson in the back of a New York City taxi cab. Here's what happened. I hopped in a taxi, and we took off for Grand Central Station. We were driving in the right lane when, all of a sudden, a black car jumped out of a parking space right in front of us. My taxi driver slammed on his brakes, skidded, and missed the other car’s back end by just inches!
The driver of the other car, who almost caused a big accident, started yelling bad words at us. My taxi driver just smiled and waved at the guy. And I mean, he was friendly. So, I said, "Why did you just do that? This guy almost ruined your car and sent us to the hospital!" And this is when my taxi driver told me what I now call "The Law of the Garbage Truck."
Many people are like garbage (rubbish) trucks. They run around full of garbage, full of frustration, full of anger, and full of disappointment. As their garbage piles up, they need a place to dump it. And if you let them, they'll dump it on you. When someone wants to dump on you, don't take it personally. You just smile, wave, wish them well, and move on. You'll be happy you did.
I started thinking, how often do I let Garbage Trucks run right over me? And how often do I take their garbage and spread it to other people at work, at home, or on the streets? It was that day I said, "I'm not going to do anymore."
Good leaders know they have to be ready for their next meeting. Good parents know that they have to welcome their children home from school with hugs and kisses. Leaders and parents know that they have to be fully present, and at their best for the people they care about. The bottom line is that successful people do not let Garbage Trucks take over their day. What about you? What would happen in your life, starting today, if you let more garbage trucks pass you by? Here's my bet. You'll be happier. Life's too short to wake up in the morning with regrets. So, Love the people who treat you right. Forget about the ones who don't.
