Conventionally grown food generally costs less, but is organic food a better choice? The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale. Supporters of organic foods ― a term whose meaning varies greatly ―are frequently telling the world that such products are safer and more nutritious than others.
The growing interest of consumers in the safety and nutritional quality of daily foods is a welcome development. However, much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs.
Almost daily, the public is surrounded by claims for “no-aging” diets, new vitamins and other wonder foods. There are numerous unsubstantiated(没证实的) reports that natural vitamins are superior to man-made ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than those treated with insect spray and the like.
Although most of these claims are not supported by scientific evidence, large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction. As a result, claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have become widely advertised and form the basis for people’s opinion.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the conventional food supply and buy only expensive organic foods instead.

Dear editor,
I am writing to ask what has happened to our young people. They are not as polite or hard-working as
my generation (一代人). I will give you two examples.
Last Friday, I got on the underground at 9:15 a.m. It was very crowded so there was no free seat. There
were some boys sitting on the seats near me. I didn"t know why they were not at school. They were talking
and laughing loudly. It was difficult for me to read my newspaper with all the noise. At the next stop, a
pregnant (***的) woman and her daughter got on with lots of shopping bags. I expected the boys to let them
sit down. They saw the woman but they did nothing. I had to ask them to give the woman and her daughter
seats. They did so but gave me a rude look.
Last Saturday, I had dinner with my friend"s family. I was glad to see his children, who I hadn"t seen for
ten years. During the dinner, I started talking about world politics with the children. It soon became clear that
they didn"t know much about it. They couldn"t tell me the name of the King of Spain or President of Italy. All
they knew about was the Internet or which singers were the most beautiful. In my days, students knew the
kings, the queens and the presidents of every country in Europe.
I worry about the future of Germany. How could these young people become good workers and parents?
They sit around Mcdonald"s after school instead of going to the library as I did at their age. Maybe they have
too much money. Perhaps some readers can give us some ideas about what to do with this "lost generation".
Yours sincerely,
Frantz Vogts
B. complain (抱怨) about young people"s act
C. show teenagers are lazy
D. express his worry about Germany"s future
B. didn"t know why they were not at school
C. felt he would be in trouble
D. expected they would get off at the next stop
B. the children knew much about the Internet
C. his friend knew little about world politics
D. the children knew little about world politics
B. the people at his age
C. today"s young people
D. the young people who are poor
mapping out a new plan for the city"s parking system. There are one million cars on the road in Shanghai
but only enough public parking space to provide room for 15 percent of these vehicles. It is no wonder
that local drivers get so worried trying to find a place to park.
The city is seeing a rise in private car owners. In March, the city sent out 2,000 private car licenses,
the highest number of licenses ever sent out in a month. And prices rose to 14,600 yuan, 500 more than
in February. Industry experts say this suggests that local people have a strong, active interest in buying
cars.
By the year 2020, the number of automobiles in Shanghai will probably reach two million. If one parking
lot is for each car, then a lot of parking space should be built for these vehicles.
Downtown Shanghai is most short of parking space. However, experts point out that simply building
more parking lots in downtown areas is not practical and doesn"t provide an ideal solution. The idea of
"Park & Ride" system has been suggested. This means that drivers can leave their vehicles in car parks
nearby subway or bus stations and ride public transport to go downtown. Based on this idea, the city will
limit the number of parking lots in downtown areas and demand higher parking fees but build more parking
areas near main subway and bus stops.
B. arguing
C. controlling
D. inspiring
B. 1,000,000
C. 150,000
D. 2,000,000
B. Less and less people bought cars in March.
C. The city sent out less private licenses in March.
D. More and more people are going to buy cars.
B. build more parking lots near bus stops
C. encourage people to buy more cars
D. build more parking areas in downtown
have banned (禁止) students from carrying mobile phones during school hours.
Mobile phone use among children has become a problem for the school this year. Several children have got
mobile phones as Christmas gifts, and more students want them.
Mary Bluett, an official, said mobile phone use is a distraction (分心的事) to students during school hours
and it also gives teachers so much trouble in their classrooms. Teachers were also saying that sometimes
students might use phone messages to cheat during exams.
She said some schools had tried to ban mobile phones. Some parents felt unhappy because they couldn"t get
in touch with their children.
Many teachers said students should not have mobile phones at school, but if there was a good reason, they
could leave their phones at school office. They also said there were many reasons why the students should not
have mobile phones at school: they were easy to lose and were a distraction from studies.
Many people say that they understand why parents would want their children to have phones, but they think
schools should let the students know when they can use their mobile phones.
B. when they are free
C. when they are at school
D. because they are children
B. the passers-by and strangers
C. their parents and friends
D. some mobile phone users
B. leave their mobile phones at school office
C. help the teachers with their work
D. get in touch with their children
entire school lives. This is also true for an American girl named Melanie in the film, College Road Trip, which
was released in the US on March 7.
Melanie"s dad, James Porter, is the chief of police for a Chicago suburb. Incredibly worrying about her
daughter"s security, he wants Melanie to attend nearby Northwestern University, where she"s already been
accepted. But Melanie, 17, really wants to go to George-town in Washington, D.C., where she"s been
wait-listed.
When she gets an unexpected interview, she decides to take a road trip with a few close female friends.
Melanie believes it is her first step toward adulthood. But despite the fact that this trip is "girls only", James
isn"t comfortable with the prospect of his little princess exploring the world without him. He wants to protect
her.
James joins the girls and hopes he can convince her to go to Northwestern. While Melanie"s father only
has the best of intentions, his presence leads to an endless series of comic encounters (遭遇).
After following their faulty GPS device deep into the backwoods, James and Melanie discover her little
brother and his pet pig have been hiding in the spare tire compartment. (隔间).
What should be a simple tire charge (充气) results in the expensive car rolling down a mountain, forcing
them to hike to a nearby hotel. There the pig ruins an outdoor wedding reception after eating an entire bag of
coffee beans.
All these disasters add spice to their trip while along the way a father and a daughter finally get the chance
to really talk to each other.
The film explores the parent-child relationship in a comic way: The gap between how close James thinks
he is to Melanie and how little he actually knows of her plans makes us laugh first and then think.
All parents, whether they have college students or not, can relate to the bittersweet realization that their
kids are growing up. Like what Melanie and James have done in the film, we all can find the balance between
staying connected and letting go.
B. call on parents to learn to balance the relationship with their children
C. tell a story which happened between an American girl and her father
D. explore the difference in parent-child relationship between the west and the east.
B. known
C. shown
D. developed
B. a hotel was destroyed by Melanie"s brother and his pet pig
C. Melanie and her father got to understand each other better after so many encounters
D. the girls had to give up their trip because of the incidents on the way
B. Northwestern University isn"t so famous as the university in Washington D.C.
C. There is no hope that Melanie will be accepted by the university in Georgetown.
D. Melanie"s father prefers her to stay not too far away from him.
the dead. Before this, five major coal mine accidents since January have already claimed lives of 287 coal
miners.
Once an accident happens, the safety measures are scrutinized, officials and owners responsible are
punished or warned or fined. But the accidents keep happening time and again. The background of this
endless disaster is a country thirsty for energy to satisfy the appetite of its economic engine.
With the rich reserve (储存) of coal and relatively limited petroleum (石油) reserve, the former makes
up 67.12 percent of energy consumption. By contrast, petroleum and natural gas take about 60 percent
of the energy consumption in other countries.
Such a situation is unlikely to change within a foreseeable future because the country still counts heavily
on coal for more and more energy. If no measures with great effects are taken to improve the safety in the
mines, the accidents will remain a long-term headache for China.
Digging coal underground is, by its nature, a dangerous job. No equipment can guarantee 100 percent
safety for the miners working underground because numerous uncertainties exist.
Most of China"s coal mines are far from being mechanized. The average output of coal for each Chinese
coal miner every day is 1 ton, while the number in the US coal mines, where the production is highly
mechanized, is 40 tons.
Mechanized production in coal mines can cut down the number of miners who have to work on the
dangerous coal face. It can also enhance the capability of the mines to detect potential danger. In this way
mine accidents will be decreased.
Admittedly, the mechanized production demands financial support.
But what is the price of a life, or a dozen, a score-a hundred? Compare these awful figures with the
misery they bring, heavy investment is worthy.
B. positive
C. unclear
D. doubtful
A. made
B. examined
C. criticized
D. discussed
B. use more natural gas
C. cut down the number of miners
D. improve mechanized production
B. it"s improper to depend too much on coal for energy consumption
C. officials and coal mine owners didn"t take safety measures seriously
D. losing lives costs much more than improving mechanized production
