“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days！”
These are the kinds of statements used in magazine，newspaper，radio and television ads，promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs，slim the face，smooth wrinkles，or in some other way to add to beauty or desirability.
Often such products are nothing more than moneymaking things for their promoters. The results they produce are questionable，and some are dangerous to health.
To understand how these products can be legally promoted to the public，it is necessary to understand something of the laws covering their regulation. If the product is a drug，FDA(Food and Drug Administration)can require proof under the Food，Drug，and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device，FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health，FDA can request the producer or distributor to remove it from the market voluntarily， or it can take legal action，including seizure(查封)of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor，which had been sold for reducing the waistline (腰围). The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously，most of the devices on the market have never been the subject of court proceedings(法律诉讼)，and new devices appear continually. Before buying，it is up to the consumer to judge the safety or effectiveness of such items.It can be inferred that the ads mentioned in the text are________.
| A．objective | B．costly | C．unreliable | D．illegal |

Country music is one of the most popular kinds of music in the United States today because it is about simple but strong human feelings and events---love, sadness, good times, and bad times. It tells real-life, stories and sounds the way people really talk. As life becomes more complicated(复杂), it is good to hear music about ordinary people.
Country music, sometimes called country-western, comes from two kinds of music. One is the traditional music of the people in the Appalachian Mountains in the eastern Unite States. The other is traditional cowboy music from the west. The singers usually play guitars, and in the 1920s they started using electric guitars. At first city people said country music was low class. It was popular mostly in the South. But during World War II, thousands of Southerners went to the Northeast and Midwest to work in the factories. They took their music with them. Soldiers from the rest of the country went to army camps（军营）in the South. They learned country music. Slowly it became popular all over the country.
Today country music is also popular everywhere in the United States and Canada—in small towns and in New York City, among black and white, and among educated and uneducated people. About 1, 200 radio stations broadcast country music twenty-four hours a day. English stars sing it in British English, and people in other countries sing it in their own languages.

About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green － a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.The passage is mainly about _____________.

Jake O' Brien，one of the central characters in Sterling R．Walker's science fiction novel The Orphan Ship，has just received some bad news. The medical school he has been going to is closing down because of financial(财务的)problems；and to make matters worse，the only other medical program in the world also happens to be on another planet. Thus，in order to become a doctor，Jake packs his suitcase and jumps on board the passenger ship Atlanta to go to Mars!
When Jake and his cousin Lorina Murphy journey to Mars Station in search of educational opportunities，they never guess they will turn into life savers. But because of the extreme poverty and child exploitation(剥削)happening on Mars，these two cousins are forced to accept their true destiny(命运)．However，they are not alone in their efforts to save the poor “street kids”．Early in the story these two heroes are joined by the crew(船员)of the Ishmael，which in the course of the story，becomes a rescue ship and a safe place for over one hundred homeless children.
In this novel，there are different themes. While fighting the cruel people who sell the “street kids” of Mars Station，the colorful characters of The Orphan Ship also manage to fall in love，find wealth，and form lasting friendships.
The real power of the story comes from the characters' expression of fellow feeling—a feeling of understanding others because you have shared similar experiences. The characters in The Orphan Ship have a sense of social duty and spiritual commitment. For example，at one point in the story，shocked by the way the homeless children have been treated，Lorina notices “a pair of black children sitting under a streetlight begging food from passersby”．Yet “no one gave the children a second look.” Fortunately，however，Lorina and her newfound friends—the crew of the Ishmael，which soon becomes the “Orphan Ship”—do indeed care for the children of Mars Station，as they join forces to provide them safe passage to earth and also a home. In this way the theme of compassion is the centerpiece of the entire novel.Jake decides to go to Mars because ______.
