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 CO are we responsible for?
A new book by Mike Berners-Lee (a leading expert in carbon foot-printing) might be able to help. The Carbon Foot print of Everything looks at the different things we do and buy, and calculates the amount of CO2 they produce, including the ingredients, the electricity, the equipment, the transport and the packaging. 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 (568 ml) of locally-brewed (酿制的) 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 300 g of CO2-but the imported beer produces 900 g! So, one pint of local beer is better for the environment than three cans of cheap foreign beer 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 65 g of CO2. However, if we eat bacon before the bike ride, it’s 200 g. 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. 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 travelling 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.
1.Which of the followings produces the smallest carbon footprints?
A. A pint of local beer.
B. A bottle of imported beer.
C. A banana before a 1.5 km bike ride.
D. Bacon before a 1.5 km bike ride.
2.According to the article, the author suggests choosing the local food because it is ________.

3.The purpose of writing this article is to ________.

It seems that everyone is travelling on holidays these days. During the travel season, roads, buses, trains and airports are packed. 1., and getting a seat at a restaurant may be impossible. You can fight these troubles alone, or you can travel, as I do, in a group led by a tour guide.
If you travel in a group, the guide will arrange everything for you. 2.. Prices are often cheaper as well, because a tour group can often get group prices and the best deals for nearly everything.
3.. Most people do not know much about the history of an attraction and interesting stories related to it. The guide’s expert knowledge will help make the trip more interesting.
If you travel in a group, you can also make more friends. 4.. Often, friendships make the trip more interesting.
5.. Your trip will be cheaper, more comfortable, more interesting and more rewarding if you travel this way rather than by travelling alone.
A. Hotels are full as well
B. If someone gets ill, others go to his or her aid
C. Taking part in a group is a fully preparatory plan
D. Your tour guide is often an expert in the places you visit
E. Using tour guides and travelling in a group is the best way to travel
F. After all, the travelling companies have been doing this job for long
G. There will be no need to worry about hotel or restaurant reservations

While they were almost unknown twenty years ago, it seems that mobile phones these days are part of everyone’s life. However, as with other inventions such as the television and the computer, they are a double-edged sword, inviting both supporters and opponents, especially in regard to their use in public places like restaurants and cinemas.
One of the strongest arguments in favor of forbidding mobiles in public places is the trouble they cause to other people. For example, although we are often asked to turn off our phones when in a cinema, the film that we are watching is often interrupted by the sound of at least five rings. To make it even worse, some people insist on continuing their conversation, even though hundreds of people can hear what they say, which often drowns out the voice from the film. As a result, many people would welcome a ban on mobile phones in places where they might disturb other people.
On the other hand, there are a number of arguments against such a ban. It is difficult to stop people bringing with them their mobile phones in public places, making it almost impossible to call for a ban. Some people would see this as an infringement（侵犯）of their rights, while other people would say they need them in case of an emergency. Despite being asked to silence their phones, some people insist on leaving them on.
It seems to me that a ban on mobile phones would not have any result in the end. People will find a way to escape a ban. Nevertheless, people should be discouraged from using them in public places, unless it is highly necessary. They should be made to know that it is bad manners to use them in certain places or at certain times. Of course, there will always be someone who thinks their call is more important than others’ peace and quiet!
53. Why are many people for a ban on the use of mobiles in public places?
A. Because hundreds of people can hear them talk.
B. Because they are asked to turn off their mobiles.
C. Because other people’s peace and quiet is more important.
D. Because many people find a way to escape a ban.
54. Among those who are against a ban, some believe that __________.
A. they can turn off their mobiles when it is necessary
B. it is their right to use their mobiles in public places
C. a ban on mobiles would not have any result
D. they can silence their mobiles when in public places
55. The author of the text thinks that __________.
A. mobiles can be used in case of an emergency in public places
B. mobiles should be turned off in public places
C. mobiles should not be banned in public places
D. it is possible to ban the use of mobiles in public places
56. Which of the following would be the best title for the text?
A. Disadvantages of Mobiles in Public Places
B. Why Not Ban Mobiles in Public Places?
C. Should Mobiles Be Banned in Public Places?
D. Manners for Mobile Users in Public Places

Call people instead of sending instant messages or texts.

They may seem like ordinary people by day but in their spare time, these office, shop and school workers bring history to life. During the week they work in shops, offices, clinics and schools, but at weekends they transform into Vikings, Romans and Medieval peasants. The world of re-enactment (重演) is booming with more and more men and women taking up the hobby of travelling to bygone times.
Factory manager of a busy printers, Brett Freeman, 46, from Nottingham, changes into “Padmore,” a Victorian street-seller selling stationery (文具).
Already a veteran (老兵) of military re-enactments, Brett joined the “Ragged Victorians” when middle-age kicked in. “I was too old to portray a soldier but I wanted to get back into the hobby and the Ragged Victorians looked the best in terms of being genuine.”
At his first event, group members gave him “loaner gear” and a year to research his character. His teeth blackened with theatrical stain, in top hat and floppy coat, Brett looks every bit his Victorian image.
Seeking inspiration, Brett dipped into the works of Victorian journalist, Henry Mayhew, who wrote about the working people of London.
“My character is inspired by the description of a stationer in Mayhew’s London Labour and London Poor. I mixed that up with my own background in print, and local historical sources to create street stationer, Padmore, which is the name of my Victorian great-great grandfather.”
“Getting into kit (装备) helps immensely and once you are in the public area you try to remain in character wherever possible.” For extra authenticity, Brett combines his language with Victorian selling patter (顺口溜), replacing the word “envelope” with “hangflups.”
“Re-enacting is great fun, but we’re always glad of a hot shower and a comfortable bed at the end of the weekend,” says Brett. “Normal life can seem very dull after a particularly good weekend. It would be wonderful to go back in time for a visit, but studying the period as I have done, makes you realise just how hard life was for our ancestors.”
1.Why does Brett choose to be a Victorian street-seller?
A.He has already played a veteran.
B.Portraying a soldier no longer fit him.
C.He is a manager of a busy printers.
D.His blackened teeth make it real.
2.What does the underlined phrase “loaner gear” in paragraph 4 mean?
A.Stage costume lent to him. B.Money paid on loan.
C.Adequate time. D.An assistant.
3.Which of the following words can best describe Brett?
A.Brave and careful. B.Kind and positive.
C.Humorous and caring. D.Serious and devoted.
4.Where can you probably find the above passage?
A.In a research report. B.In a magazine.
C.In a travel brochure. D.In an advertisement.

School children are using mobile phone applications to do their homework, which seem to be increasing during summer vacations. But instead of blaming students for their behavior, we should say no to too much homework. This is important because by using mobile phone applications to do their homework, students don't add much to their knowledge, says an article in Guangzhou-based Yangcheng Evening News. Excerpts (摘录):
Using mobile phone applications to do homework is no different from copying from someone else's work. This is the opinion of a vast majority of teachers. Students who seek cell phone apps help to do their homework will pay dearly during major exams when they cannot seek the help of such applications, the teachers say.
The heavy load of homework Chinese students are burdened with, said to be the heaviest in the world,has led to the popularity of these applications.
Senior high school students in China rarely go to bed before 11 pm. A report in Shanghai published in2013 showed that students in the city on average spend 28.2 hours in class every week, the 9th highest among 65 countries and regions surveyed. Also, they spend an average of 13.8 hours a week doing homework, most in the world.
There is no association between the amount of homework one does and the amount of knowledge one gathers. In fact, a research by Australian experts shows that the result is exactly the opposite: the more hours students spend doing homework, the less effective they will be in gaining knowledge.
The United States is one of the countries where students do little homework, but that has not damaged the country's academic status in the world.
So, it's time Chinese schools understood this fact and freed students of the unnecessary burden of homework.
1.What’s the writer’s attitude toward the students’ using mobile phone applications to do their homework?
A. Supporting B. Understanding
C. Scolding D. Praising
2.The cause of the students’ using mobile phone applications to do their homework is______.
A. the heavy burden of homework
B. the advance of modern technology
C. the pressure of the students’ parents
D. the influence of other countries
3.What does the underlined phrase “pay dearly” mean?
A. be rewarded B. be dismissed
C. provide much money D. suffer a lot
4.Which of the following is probably the best title?
A. Free kids of the burden of homework.
B. Stop using mobile phones to do homework.
C. Spend less time to gain much knowledge.
D. Improve China’s academic status in the world.
