Many students eat their breakfasts on the way to school or in the dinning-room．But some of them don’t really know how to eat well when eating out．
Here is some important advice．The first is to eat less fast food．The most obvious harm of eating too much fast food is weight gaining because of too much fat．Young people and adults are at risk of disease related to weight．
Too much fast food can drag your body down．French fries, for example, were recently found to contain much more acrylamide（丙烯酰胺） than other food．This may cause cancer．Actually, deep fried food all contains acrylamide．So don’t eat it too often．
Soda is another thing you should watch out for．Cokes and other sodas contain a lot of sugar and can slow down a person’s calcium absorption, so it’s best to drink as little soda as possible．
Food in the dinning-room may not be as tasty as fast food, but it’s actually easier to make healthy choices．Human bodies need variety．You can have a dinner that balances lean proteins, vitamins and complex carbohydrates（碳水化合物）．In other words, a meal with fish or meat, vegetables and some bread or rice will provide you with most nutrients that the body needs．
Some snacks, on the other hand, will help keep you going until your next big meal．It is natural for teenagers, especially boys, to feel hungry during school time．Don’t forget to take some foods, like whole-grain biscuits or low-fat milk in your school bag．

In Britain today, is it possible to tell a person’s class just by looking at him? Physical details alone tell us about health, diet and the type of work a person does. A hundred years ago the working class often looked unhealthy, small and they were either too thin or too fat. The upper classes were often tall, sporting types who were used to a good diet and looked healthy. Today living and working conditions have improved, and such descriptions are no longer true. People are taller now than a hundred years ago. Everyone in Britain today is able to have free medicine, a good diet, acceptable working conditions and enough rest and leisure.
The clothes people choose to wear, however, do provide information about their backgrounds. Expensive clothes look expensive and show their wearer is rich. Clothes can provide other clues as well. The upper classes appear to be less interested in fashion and wear good quality clothes in non-bright colours, made of natural material like wool, leather and cotton. Lower working-class people often choose clothes in bright colours, made of man-made materials. A sociological explanation for this would be that colour and interest are missing from their lives, and therefore any opportunity to produce this is taken.
Clothes are available at a price within most people’s reach. New clothes make the wearer feel good and show some degree of wealth to the outside world. Today it is the younger people who spend most money on clothes. Fashion is no longer for the upper classes and the rich. Young people from all social classes spend a lot of money on clothes. Some new fashions are started by working—class people who want to look different and feel important. They want people to look at them.
1. In the past, a person’s appearance could not tell other people about his ________.
A. health B. diet C. occupation D. habits
2. The clothes people choose to wear tell us about their ________.
A. education B. richness C. backgrounds D. hobby
3. A working—class person may start a new fashion because ________.
A. she wants to draw the attention of other people
B. she wants to look different and healthy
C. she wants to show their wealth
D. she wants to show their taste
4. Which of the following statements is NOT true?
A. Expensive clothes look expensive and show the wearer is rich.
B. Working—class people prefer clothes in bright colours because they lack colour in their lives.
C. Today, it is still the upper class people who spend most money on clothes.
D. Today, fashion is no longer for the upper classes and the rich.

Inside the pleasingly fragrant cafe, So All May Eat(SAME) in downtown Denver ,the spirit ofgenerosityis instantly noticeable :donation box stands in place of a cash register. Customers here pay only what they can afford, no questions asked.A risky business plan, perhaps, but SAME Café has done one unchangeable thing in the Mile High City for six years: Open only at midday, the restaurant allows poor local customers who cannot pay to work as volunteers instead. They can act as waiters and waitresses, and dishwashers, or look after the buildings and equipment for the cafe.
It’s based on trust, and it’s working all right”, says co-owner Brad Birky, who started the café in 2006. Previously volunteering at soup kitchens, the Birkys were dissatisfied with the often unhealthy meals they served there. “We wanted to offer quality food in a restaurant where everyone felt comfortable, regardless of their circumstances,” Birky says. SAME’s special lunch menu changes
daily and most food materials are natural and grown by local farmers. The café now averages 65 to 70 customers (and eight volunteers) a day. And the spirit of generosity behind the project appears to be spreading. In early 2007,one volunteer who had cleared snow for his meals during t he long
winter said goodbye to the Birkys, He said he was going to New Orleans to help with the hurricane clearing up,” says Birky.
【小题1】What can we learn about the soup kitchens the Birkys previously worked for?
| A．They refused to have volunteers. |
| B．They offered low quality food. |
| C．They provided customers with a good environment. |
| D．They closed down because of poor management. |
| A．The customers who cannot pay can work as volunteers instead. |
| B．More volunteers will go to new Orleans for the hurricane cleanup. |
| C．Many new cafes will be opened to offer free lunches in the town. |
| D．The lunch menu has remained the same since the café was started. |
| A．unfavorable | B．doubtful | C．cautious | D．approving |

科目：高中英语 来源：2014届浙江省高一下学期期末考试英语试卷（解析版） 题型：阅读理解
Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants produce volatile compounds (挥发性化合物) —— chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from such volatile compounds to attract insects such as bugs and bees.
Plants can also discover volatile compounds produced by other plants. A tree under attack by hungry insets, for instance, may give off these chemicals in order to let other trees know about the attack. In response, the other trees may send off their chemicals to keep the bugs away —— or even chemicals that will attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying: a chemical sensor (传感器) called an “electronic nose”. The “e-nose” can tell such compounds as plants make. When plants are attacked, scientists say, the e-nose could help quickly decide whether plants are being eaten by insects. But today, the only way to spot such insects is to inspect individual plants by observing them. This is a challenging task for managers of greenhouses, including those that can house thousands of plants. The research team is working with an e-nose that can recognize volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds based on the interactions (相互作用), and then the e-nose will give off electronic signals that the scientists can analyze by using computer software.
To test the e-nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all being common greenhouse crops. Then scientists collected samples of the air around damaged leaves from each type of crop. These plants had been damaged either by insects or by scientists who made holes in the leaves with a hole punch (打孔器).
The e-nose, it turns out, can identify healthy cucumber, pepper and tomato plants based on the volatile compounds they produce. It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage —— by insects or with a hole punch —— had been done to the tomato leaves.
With some fine-tuning (微调), a device like the e-nose can one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this can also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, India, who studies smells of flowers and plants. Hopefully, scientists believe, the device can bring large benefits to greenhouse managers in the near future.
