People and the sources of air pollution are found in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes from cars. Statistics show that 93 percent of all auto trips are within cities. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country.
On the average, we throw away more trash and garbage than the year before. The burning of garbage contributes to air pollution. Many major industries are also responsible for the dirty air in the around cities. The fumes from iron, steel, chemical, and petroleum production add particles to the air.
The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy for traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes（气体）may kill trees and plants and cause metal to corrode. In some of the larger cities, these fumes endanger the live of human beings by contributing to lung diseases and causing early death.The main idea of the passage is that _________.

It’s a too long story — 17 months to be exact — with an ending that’s short and sweet. Ruthie has, finally and happily, been reunited with her family.
The story goes back to October, 2005. Ruthie, 8 months old, was sitting on the back seat of the family car when her owner walked hurriedly into a Long Island store. When Nancy Noel returned a few minutes later, Ruthie was nowhere in sight.
Nancy Noel and her husband, Lincoln Werden, got in touch with Nassau County police, put up flyers (小传单) around their Manhasset neighborhood. But no sightings of Ruthie were reported. Until last week, that is, someone sent Ruthie to a Manhattan shelter after finding her walking slowly around the Bronx — 25 miles from where she was taken on that fateful October day.
And then, shelter workers searched Ruthie for a possible microchip (微芯片) — she had one fixed under her skin. It showed her family’s name and address. Ruthie was immediately reunited with Nancy Noel and her daughter, Sara Werden.
“We never thought we would see her again,” said Sara Werden. “We were just amazed.”
She’s no longer the tiny pup they last saw. In fact, Ruthie gained (增加) 10 pounds during her months away from home. She’s on a diet now, and has already lost one and a half pounds. Ruthie also has a new friend to play with. The family had got another dog, named Holly, after losing the hope of ever finding their beloved Ruthie.According to the passage, when did Ruthie get together with her family?

People do not analyze（分析） every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However , when all these methods fail, the person with a problem has to start analyzing. There are six stages in solving a problem.
First the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must see that there is a problem with his bicycle.
Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears（齿轮） ,the brakes, or the frame. He must make his problem more specific.
Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decides that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully. After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gearwheels and replace the old ones; tighten or loosen the gear wheels.
Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gearwheels. He immediately realizes the solution to his problem: he must clean the gear wheels.
Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short, he has solved the problem.What is the best title for this passage?
| A．Six Stages for Repairing Sam’s Bicycle |
| B．Possible Ways to Problem-solving |
| C．Necessities of Problem Analysis |
| D．Suggestions for Analyzing a Problem |
In analyzing a problem we should do all the following except __________.
| A．recognize and define the problem |
| B．look for information to make the problem clearer |
| C．have suggestions for a possible solution |
| D．find a solution by trial or mistake |
By referring to Sam’s broken bicycle, the author intends to _________.
| A．illustrate the ways to repair his bicycle |
| B．discuss the problems of his bicycle |
| C．tell us how to solve a problem |
| D．show us how to analyze a problem |
Which of the following is NOT true?
| A．People do not analyze the problem they meet. |
| B．People often accept the opinions or ideas of other people. |
| C．People may learn from their past experience. |
| D．People can not solve some problems they meet. |
Keeping pace with teachers is a fine way to study English. Teachers are experienced and their plans are systematic. But remember to work in a way that suits you. It's important to learn from past mistakes as well. Keep a notebook to make a record of the mistakes you make－it'll help you avoid making the same ones later.
The time of life may be hard，but you're not alone. You may be busy studying，but you can show your care by calling your friends or sending short messages. Don't let your friendships die.
It's as important to live well as it is to study well. Going to bed no later than 11：30 pm is vital（极重要的）. It puts you in the right mood for the next day. You needn't follow a special diet，but make sure you are eating nutritious meals each day.
The person who plays well，studies well. Having a lot of schoolwork doesn't mean having to give up other activities. Playing basketball or having a talk with your classmates can relax yourself. Time out is not a waste of time but helps you study more efficiently.
Besides taking the big exam，you have other choices for college. I took the independent enrollment exam held by Peking University and some other students even were preparing to study abroad. Pay attention to any relevant（相关的）information you can find，whether it's from school，the news media or other sources.What should you do if you want to keep your friendship fresh?
| A．Have frequent talks with them. |
| B．Always have lunch with them. |
| C．Remain them at some distance. |
| D．Keep connection by some ways. |
