that today"s children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children aged 9 to 17 exhibit a higher level of anxiety today than children who were treated for
mental illness 50 years ago.
Why are America"s kids so stressed? The report cites two main causes: increasing physical isolation
(隔离) brought on by high divorce rates and less involvement in community, among other things and a
growing perception that the world is a more dangerous place.
Considering that we_can"t_turn_the_clock_back,_adults can still do plenty to help the next generation.
At the top of the list is nurturing(培育) a better appreciation of the limits of individualism. No child is
an island. Strengthening social ties helps build communities and protect individuals against stress.
To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your
family will thank you later. They will have more time for facetoface relationships, and they will get more
sleep.
Limit the amount of virtual(虚拟的) violence your children are exposed to. It"s not just video games
and movies; children see a lot of murder and crime on the local news.
Keep your expectations for your children reasonable. Many highly successful people never attended
Harvard or Yale.
Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a
good model for your kids. Sometimes anxiety is unavoidable. But it doesn"t have to ruin your life.
B．were considered less individualistic
C．were less isolated physically
D．were probably less selfcentered
B．The social reality children are facing cannot be forgotten.
C．It"s impossible to slow down the pace of change.
D．Lessons learned from the past should not be forgotten
B．confusing
C．surprising
D．questionable
B．TV and computer play an important role in isolating children from the real world.
C．Exercise does not help to lessen children"s anxiety.
D．Sometimes local news about crime and murder also affects children a little

At school
The school day begins at 8:30. Then students assemble in their homeroom classes for the day"s studies. Each homeroom has an average of 40-45 students. Students stay in their homeroom classrooms for most
of the school day. Only for physical education, laboratory classes, or other subjects requiring special
facilities(设备) do students move to different parts of the school. Between classes and at lunchtime,
classrooms can be noisy, lively places. Some schools may have a cafeteria(自助餐厅), but most do not.
In most schools, students bring a box lunch from home, prepared by the mother in the early morning hours.
Japanese students spend 240 days a year at school, 60 days more than American students. Students in high schools take three years" each of the following subjects mathematics, social studies, Japanese, science, and English. Other subjects include physical education, music, art, and moral(道德的) studies. All the
students in one grade level study the same subjects. Given the number of required subjects, electives(选修科目) are few.
Afterschool Activities
Club activities take place after school every day.Students can join only one club, and they rarely change clubs from year to year, so the clubs are relatively stable. Clubs are made up of sports clubs ( baseball,
soccer, judo, kendo, etc.) and culture clubs(English, broadcasting, science, etc.). New students usually
are encouraged to select a club shortly after the school year begins in April. Clubs meet for two hours after school each day and many clubs continue to meet during school vacations.
B．in school cafeterias
C．at home
D．in homeroom classrooms
B．200
C．240
D．300
B．never
C．seldom
D．often
B．students must stay in homeroom classrooms for physical education
C．there are few subjects for students to choose except the required ones
D．there will not be any club activities during school vacations
B．Global warming-a world problem
C．The fast increase in recent years
D．What we should do to avoid greenhouse gases producing
E．The earth is becoming warmer
F．Different opinions on the cause of global warming
Is the world warming up? According to many reports, the answer is yes. Eleven of the hottest years
since 1850 appeared between 1995 and 2006. Last year, the United Nation"s Intergovernment Panel on
Climate Change (IPCC) reported the earth was about 0.75 ? warmer than it was in 1850. While this
doesn"t sound like a lot, a small difference in average temperature can make a big difference in climate.
During the last Ice Age, the planet was only about five degrees colder than now.
2．________
It"s all about the speed at which temperatures are changing. In the past,temperatures moved up or down step by step. But in the 20th century, especially since 1976, temperatures have likely risen more quickly
than during any century in the last 1000 years. Warming may bring improved harvests to northern countries such as Canada and Russia. However, many species won"t like these conditions. They begin moving
towards cooler places and cause lots of trouble to human world.
3．________
The IPCC reported that human activity is very likely responsible for increasing the greenhouse effect.
Some gases cause the air to take in heat energy. Without the greenhouse effect, the earth"s average
temperature would be－18? rather than the present comfortable 14.6 ?. The main greenhouse gases are
carbon dioxide, water vapor and some other gases. Burning oil,coal and waste add to the carbon dioxide,
and it has increased 35% since 1850.
4．________
Many researchers have found that natural forces alone don"t explain the temperature increases over the
last 30 to 40 years. Their study shows that as carbon dioxide goes up, temperature will rise, too. But some scientists don"t agree. They think the effect of human produced greenhouse gases is very small compared
to the normal changes that the climate causes.
5．________
When asked whether humans are causing the world warming,Carl Wunsch, a professor at Massachusetts Institute of Technology says, "It seems very likely from what I"ve seen. Is it 100% sure? No. There is
something to do with natural changes." Does that mean we should have a "waitandsee" attitude? No. He
points out we buy house insurance not because we are sure our homes will be on fire, but because it"s a
danger we"d rather avoid.

If you believe your pronunciation is good enough to 8 because it is good enough for your teacher

| Even plants can run a fever, especially when they"re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago, adopting the infrared(红外线)scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don"t have pest problems. Even better, Paley"s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a colourcoded map showing where plants were running "fevers". Farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise would. The bad news is that Paley"s company closed down in 1984, after only three years. Farmers resisted the new technology and longterm backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States, " says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago. 1. Plants will send out an increased amount of heat when they are________. A. facing an infrared scanner B. sprayed with pesticides C. in poor physical condition D. exposed to excessive sun rays 2. In order to apply pesticide spraying precisely, we can use infrared scanning to________. A. estimate the damage to the crops B. draw a colourcoded map C. measure the size of the affected area D. locate the problem area 3. Farmers can save a considerable amount of pesticide by________. A. resorting to spotspraying B. transforming poisoned rain C. consulting infrared scanning experts D. detecting crop problems at an early stage 4. The application of infrared scanning technology to agriculture met with some difficulties-_______. A. its high cost B. the lack of official support C. the lack of financial support D. its failure to help increase production 5. Infrared scanning technology may be brought back into operation because of________. A. full support from agricultural experts B. growing concern about the excessive use of pesticides on crops C. the forceful promotion by the Department of Agriculture D. the desire of farmers to improve the quality of their produce | |||

| Nuclearpowered aircraft carriers are considered one of the most important marine weapons in the 20th century. So far, only two countries in the world, the USA and France, have ever produced them. But these fearful fighting machines are about to enter Asia. The US Navy said last month that one of its nine nuclearpowered aircraft carriers will be sent to Japan to replace the diesel(柴油)powered carrier Kitty Hawk in 2008. In an agreement on October 30, the two countries also planned to level up their military (军事的) cooperation and the USA called for Japan to take a larger role in alliance military moves. It will be the first time that a nuclearpowered carrier is based in Japan. Bombed by US forces in World War ? at Hiroshima and Nagasaki, Japan is the only world country to have been attacked by a nuclear weapon. Therefore, the citizens are highly sensitive to where nuclearpowered weapons are based. "A radiation leak at Yokosuka would kill 100,000 people as far away as Tokyo, and could cause billions of dollars in damage, " said Masahiko Goto, leader of a protest group in Yokosuka. His group has collected more than 300,000 signatures of people across Japan opposed to the nuclear carrier. The 44yearold Kitty Hawk, the US Navy"s oldest active ship, has been based in Yokosuka since 1998. It had returned to the US to be decommissioned in 2008. The new carrier, yet to be unveiled,_ will travel faster, be capable of supporting longer operations and carry with it the Navy"s most modern technology. Experts pointed that this change is not only to strengthen the USJapan military alliance but also to keep the military power of China and North Korea within limits. However, even Japanese experts don"t believe that the two countries are threats to the region. "There is no need for Japan to have a nuclear carrier as defense, " said Tetsuo Maeda, an international relations professor at Tokyo International University. He said that the change of ship indicates an increased military capability in the region, much more than what is needed. 1. With such a formidable weapon to enter its country, Japanese citizens ________. A. are aware of its benefits to the country B. are anxious about its potential danger C. are curious about the advanced technology D. are against where the carrier will be based 2. The replacement of the aircraft carrier is intended to________. A. set up a kind of base in Japan B. strengthen the USJapan military alliance C. show Japan"s greater military capability D. get rid of the dated marine weapon 3. From the story, we learn that________. A. no other countries except the USA and France possess aircraft carriers B. Japan has long planned to increase its military capability with new weapons C. Japan will be the first country in Asia to have a nuclear aircraft carrier D. Japan will be the third country to produce a nuclearpowered aircraft carrier 4. The underlined word "unveiled" in the fifth paragraph probably means________. A. perfected B. discussed about C. produced D. brought to view 5. By his remark in the last paragraph, the professor means that________. A. he is quite confident of their military defense B. he is completely opposed to a new nuclear carrier C. what is needed is far more than a nuclear carrier D. it is unnecessary to guard against the two countries |
