Federal regulators Wednesday approved (批准a plan to create a nationwide emergence alert（警报）system using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates（估计）more than 48billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation's emergency alert system. The act tasked the Federal Communications Commission（FCC）with coming up with new ways to alert the public about emergencies.
"The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alert system by carriers -telecommunications companies is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alerts.
There would be three different types of messages, according to the rules.
The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction（绑架）emergencies, or so-called Amber Alerts.
The service could be in place by 2010.
What is the purpose of the approved plan?

A．To warn people of emergencies via messages.

B．To popularize the use of cell phones.

C．To estimate the monthly number of messages.

D．To promote the wireless industry.

The improvement to the present system is in the charge of________.
A．CTIA B the Warning Alert and Response Network
C．FCC D．federal regulators
An alert message will NOT be sent if________.

A．a child loses his way

B．a university shooting happens

C．a natural disaster happens

D．a terrorist attack occurs

Which of the following would be the best title for the text?

A．Cell Phone Alerts Protecting Students

B．Cell Phone Alerts by Wireless Industry

C．Cell Phone Alerts of National Disasters

D．Cell Phone Alerts Coming Soon

Britain and other nations should be well on with the building of huge industrial complexes (工业园区)for the recycling of wastes within fifteen years. The word rubbish could lose its meaning because everything that goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else.
The latest project is to take a city of around half a million inhabitants (居民) and discover exactly what raw materials go into and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste was built just outside the city. This plant would recycle not only metal such as steel, lead (铅) and copper, but also paper and rubber as well.
Another new project is being set up to discover the best way of sorting and separating the rubbish. When this project is completed, the rubbish will be processed like this: First, it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that rollers will break up everything that can be broken. Finally, the rubbish will pass under magnets (磁铁), which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the final stage.
The first full-scale (完全的) giant recycling plants are perhaps fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long.
64. The underlined phrase “be well on with…” (Para. 1) most probably means _______.
A. have completed what was started      B. get ready to start
C. put an end to                               D. have achieved a great deal in
65. What is NOT mentioned as a part of the recycling process described in paragraph three?
A. Sharpening metal bars.            B. Sorting out small pieces of metal.
C. Breaking up whatever is breakable.   D. Separating lightest elements from the heavy ones.
66. What’s the main reason for big cities to build their own recycling plants?
A. To get raw materials locally.             B. To deal with wastes in a better way.
C. To get iron and steel from those plants.     D. To protect the environment from pollution.
67. The first full-scale huge recycling plants ______.
A. will be built fifteen years later
B. began to operate fifteen years ago
C. will probably be in operation in fifteen years
D. will probably take less than fifteen years to build
68. The passage is mainly about _______.
A. a cheap way to get energy       B. the location of recycling plants
C. new ways of recycling          D. the probability of city environment

Millions of aircraft take off around the world every year. The skies they fly in seem limitless—miles of empty space. But, with the number of flights increasing each year, this emptiness no longer exists. Researchers in the world of aviation（航空）are worried about the increasing pressure on pilots and ground controllers. And increasing collisions, occurring at or near an airport, have called attention to the need for more aids（辅助设备）to aviation control.
People who travel the skies are not certain about air safety. A great deal of money is spent on new and bigger aircraft and airports to deal with the vast increase in passengers travelling by air. Only a small percentage of this money is spent on navigation（导航）and other aids. Actually, suitable electronic equipment has long existed, and many companies market safety aids designed to make it safer for aircraft to take off, fly any distance, and land, whatever the weather. Yet, there are two problems to be solved. The first is to get governments, airlines and airport officials to agree to basic levels of safety aids. The second problem is to find a way of meeting these basic requirements.
But no matter how well the equipment works, operators of the equipment still play an important role. Communications between pilots and ground controllers are extremely important to air safety. It is worth pointing out that the mishearing or misunderstanding of instructions in English and the use of another language, in an international conversation, have led to two recent aircraft accidents. A new type of instrument（仪器）called FLIGHTWATCH would help pilots prevent airport collisions. It would be particularly helpful near airports.
60. The increasing number of flights leads to the fact that ________.
A. flying is no longer limited in the sky
B. there is no empty space for aids to aviation control
C. piloting and controlling planes is getting more difficult
D. the pressure on the ground becomes greater
61. There is uncertainty about air safety because ________.
A. planes become bigger for the increasing number of passengers
B. money spent on electronic equipment is far from enough
C. suitable electronic equipment hasn’t been invented yet
D. it is dangerous for planes to take off or land
62. The underlined word “collisions” probably means ________.
A. accidents in which two planes hit each other
B. misunderstandings between pilots and ground controllers
C. quarrels among passengers
D. breakdowns of new types of instrument
63. It can be inferred from the passage that ________.
A. governments and officials have paid great attention to air safety
B. there should be more companies to sell new safety aids
C. English should be used in an international conversation
D. understanding between pilots and ground controllers should be improved

Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing? Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager.
　　“I would never have said to my mom, ‘Hey, the new Weezer album is really great. How do you like it?’” says Ballmer. “There was just a complete gap in taste.”
　　Music was not the only gulf (分歧). From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits.
　　Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent-child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood.
　　No wonder greeting cards today carry the message, “To my mother, my best friend.”
　　But family experts warn that the new equality can also result in less respect for parents.
　　“There’s still a lot of strictness and authority on the part of parents out there, but there is a change happening,” says Kerrie, a psychology professor at Lebanon Valley College. “In the middle of that change, there is a lot of confusion among parents.”
　　Family researchers offer a variety of reasons for these evolving(演化的) roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic process that encourages everyone to have a say.
　　“My parents were on the ‘before’ side of that change, but today’s parents, the 40-year-olds, were on the ‘after’ side,” explains Mr. Ballmer. “It’s not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now.”
72. Which of the following shows that the generation gap is disappearing?
　 A. Parents help their children develop interests in more activities.
　 B. Parents put more trust in their children’s abilities.
　 C. Parents and children talk more about sex and drugs.
　 D. Parents share more interests with their children.
73. The change in today’s parent-child relationship is ______.
A. more confusion among parents
B. new equality between parents and children
C. less respect for parents from children
D. more strictness and authority on the part of parents
74. By saying “today’s parents, the 40-year-olds, were on the ‘after’ side,” the author means that today’s parents ______.
A. follow the trend (趋势)of the change
B. can set a limit to the change
C. fail to take the change seriously
D. have little difficult adjusting (调整)to the change
75. The purpose of the passage is to ______.
　　A. describe the difficulties today’s parents have met with
　　B. discuss the development of the parent-child relationship
　　C. suggest the ways to handle the parent-child relationship
　　D. compare today’s parent-child relationship with that in the past
