Yellowstone Weather
Yellowstone National Park is at high altitude. Most of the park is above 7500 feet (2275 meters).
Yellowstone’s weather is unpredictable. In summer, it may be warm and sunny with temperatures in the high 70s. At night in any given month, the temperature may drop close to freezing. So it is best to come prepared for cold evenings and mornings, especially if you are camping or hiking. When you leave your campsite, please leave it prepared for possible thundershowers and wind.
A sunny warm day may become fiercely stormy with wind, rain, sleet and sometimes snow. Without enough clothing, an easy day hike or boat trip can turn into a battle for survival.

Some experts feel that cars are certain to fall into disuse. They see a day in the not-too-distant future when all cars will be deserted and made useless. Other experts, however, think the car is here to stay. They hold that the car will remain a leading means of city travel in the foreseeable future.
The car will undoubtedly change greatly over the next 30 years. It should become smaller, safer, and more practical, and should not be powered by the gas engine. The car of the future should be far more pollution-free than present types.
Unless changes take place in the power system, the car in the future will still be the main problem in city traffic jams. One suggested solution to this essential problem is the automated (自动的) system, which seems to hold water.
When the car enters the highway system, a small arm will drop from the car and connect with a rail, which is similar to those powering subway trains electrically. Once joined to the rail, the car will become electrically powered from the system, and control of the car will pass to a central computer. The computer will then monitor all the car’s movements. The driver will use the telephone to dial instructions about his position and the place he heads for into the system. The computer will find the best way and reserve space for the car all the way to the correct exit from the highway. The driver will be free to relax and wait for the call that will warm him of his coming exit. It is believed that an automated highway will be able to deal with 10,000 cars per hour, compared with the 1,500 to 2,000 cars that can be carried by a present-day highway.
48. What is the main concern of the author of the passage?
A. How to make cars pollution-free. B. How to make cars smaller and safer.
C. How to solve the problem of train jam. D. How to develop an automated subway system.
49. We can infer from this passage that __________.
A. the car connected to the rail on the highway will be powered by electricity.
B. The lack of oil is forcing people to find new means to power automobiles.
C. The driver under the system will be told where to get out of the highway.
D. The future car will become larger, faster, prettier and less expensive.
50. What provides cars with electric power in an automated highway system?
A. An engine. B.A rail. C. A computer controller. D. A small arm.
51. Which of the following statements is true according to the passage?
A. The driver puts his information in the system by email.
B. The new system can deal with 10 times as many cars as the present one.
C. After entering the automated system, the driver needs to do nothing but relax.
D. Some experts are not confident of the future, while the view of the author is hopeful.

查看习题详情和答案>>afraid they will be played jokes on by a bully. One study found that 52% of children reported being bullied
at least once a week. Sixty percent say that they know someone who could harm them. One student was
always being joked because he was short. He didn't like to go to school because he had to face the bullies.
Some children choose not to go to school at all so they can avoid the bullies. When they miss school,
students fall behind their classmates. A new program is helping put an end to this problem. The program
is teaching kids how to deal with bullies. This is helping more children feel safe in school.
One school principal is working to end this negative behavior. Last year, he decided to let students know
bullying is not allowed there. Students are now encouraged to report bullies and stand up for themselves.
Those found to be bullies face harsh penalties (处罚). Students at his school participate in a program called
"Be Bold". In this program, students work together to prevent violence. They do skits and go into classrooms
to talk about the problem. They give other students strategies (策略) on how to deal with bullies.
The principal says that the school has changed since he has addressed the bullying problem. But there
are other steps parents can take to help their children with this problem. First, students and their parents
should know the school's rules about bullying and what they should do if it happens. Second, children should
be taught to stand up for themselves. They should try to resolve issues by talking them out. If the problem
continues, parents and children should record each incident. Children should tell someone if they are being
joked. Many children keep bullying a secret.
Parents should look for warning signs of bullying. These can include cuts and bruises (瘀伤), worrying,
wanting to stay home from school, or a sudden drop in grades.
B. Some students didn't go to school because they had to face the bullies.
