Other encouraging results can be found in early childhood education programs, which provide stimulating intellectual experiences for disadvantaged children．In one study, children from low-income families were given enriched environments from early infancy(婴儿期) through preschool．By age 2 their IQ scores were already higher than those in a control group．More important, they were still 5 points higher seven years later．High-quality enrichment programs such as Head Start can prevent children from falling behind in school.
A particularly striking environmental effect is the fact that 14 nations have shown average IQ gains of from 5 to 25 points during the last 30 years．These IQ boosts, averaging 15 points, occurred in far too short a time for genetics to explain them．It is more likely that the gains reflect environmental forces, such as improved education, nutrition, and living in a technologically complex society.

ith pollution and clear the air.Chinese cities will need to put efforts to clear up the sky when
a new department to improve regional air quality is set up by 2015, according to the latest plan released by the State Council．Besides the existing pollution control program for S02, regional emission caps （区域排放上限） for other certain chemicals will be established in the three key air polluting areas— rhe Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region．Coal-consumption caps will also be tried out in some areas, according to the plan．
The plan is aimed at dealing with regional air pollution—such as acid rain and smog—which have become increasingly obvious in China in recent years and caused a severe threat to people"s health, Zhang Lijun, vice-minister of environmental protection, said in an interview on Monday.
The air quality in a city affects the regions nearby because pollutants （污染物）can travel through the atmosphere, said Chai Fahe, vice-direc
tor of Chinese Research Academy of Environmental Sciences．“So efforts to reduce air pollution in a single city, targeting a certain pollutant w
ill not oe enough," Chai said．Zhang said the country"s major industrial districts—the Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region—have recorded more than 100 misty days annually in recent years．
These three regions, home to at least 200 millio
n people, occupy only 6．3 percent of the country"s area but consume 40 percent of the country"s coal and produce half of its steel, according to official figures．Studies also show that the visibility （能见度） in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s, as a result of air pollution．
Liaoning province, the Shandong Peninsula, Wuhan in Hubei province and its surrounding area, the Changsha-Zhuzhou-Xiangtan region in Hunan province, the Chengdu-Chongqing region, and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs, according to the plan．
The new plan also requires an improved air quality system, which will measure the pollution levels．"The current system, which only measures some major pollutants, cannot reflect the true picture．" said Chai．
小题1:It will not be enough to reduce air pollution in a single city because ______.
A．air pollution has b een becoming more and more serious in recent years |
| B．air pollution like acid rain and smog is threatening people"s health |
| C．air pollutants in a city can travel in the sky and affect nearby areas |
| D．air pollutants stay in fixed places over the cities |
| A．123 to 115 km |
| B．137 to 145 km |
| C．123 to 145 km |
| D．115 to 137 km |
| A．to inform readers of the damage caused by air pollution |
| B．to introduce the new plan to control air pollution |
| C．to provide official figures of air pollution levels |
| D．to point out the regions affected by air pollution |
| A．The major pollutants． |
| B．The key polluted areas． |
| C．The major polluted cities． |
| D．The pollution levels． |
This was the conclusion of a team of scientists from China"s State Forestry Administration and the World Nature Fund．
The South China tiger, also known as the Chinese tiger, is native to southern China．In the 1950"s, there were over 4000 tigers found in mountain forests in the country．But due to the destruction of their natural habitat （栖息地） and uncontrolled hunting, it has been pushed on to the list of the world"s top ten most endangered species．
Sixty-six of the big cats can be found in the cages of a dozen zoos around China．But they are nothing like their wild cousins．They have lost their natural skills such as hunting and killing．If they were set free they could not look after themselves．
"Breeding has damaged the quality of the species", said Pei Enle, deputy director of the Shanghai Zoo．
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa．Four of them have already arrived．Progress has been made as two elder tigers have recovered some of their instincts（本能） and can hunt wild animals by themselves at the African base．
" South Africans are very experienced in reintroducing big animals to the wild．The country has very good natural conditions for the tigers to learn in", said Lu Jun, office director of the National Wildlife Research and Development Center．" We tried in Fujian Province, but it was not successful as there was not a complete eco-chain（生物链） and there was a lack of space．"
The tigers should return to China in 2007 when the reservations in Fujian are ready．
小题1:What is the main reason for the South China tiger becoming one of the world"s top ten most endangered species?
| A．Because it has lost its natural instincts． |
| B．Because there is not a complete eco-chain． |
| C．Because there is no space for it． |
| D．Because uncontrolled hunting has destroyed its natural living conditions． |
| A．Its effect still remains to be seen． |
| B．Two tigers can already compete with their wild cousins． |
| C．Some of the tigers are already on the road to recovering their natural skills． |
| D．The tigers should be able to recover their instincts completely by 2007． |
| A．they are no longer feared by other wild animals |
| B．they don"t know how to hunt or kill |
| C．a complete change has resulted in the species because of breeding |
| D．to reintroduce them into the wild has become an urgent task |
| A．To help the tigers recover their ability to live in the wild． |
| B．To provide them with a better environment． |
| C．To get the tigers to go on a tour． |
| D．To find a complete eco-chain for them． |
| A．Because the tigers can hunt wild animals by themselves at the African base． |
| B．Because South Africans are skilled at dealing with the tigers． |
| C．Because there is a complete eco-chain and enough space there． |
| D．Because the country has good natural conditions for the tigers to learn in． |
From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go．This battery-powered, zero-emission (meaning it doesn"t pollute the air) vehicle runs mainly on renewable energy．Solar panels on the Eclectic"s roof absorb sun rays when you"re driving．On windy days, you can connect a machine to the car"s roof that collects energy from the wind while you"re parked．The Eclectic"s top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged．Zipping (迅速行进) around the neighborhood has never been better.
Here"s an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock"s tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries．There are two sets of metal electrodes (电极) inside the water tank．Water contains ions (离子) that carry negative and positive charges．These ions complete a charge between the electrodes, creating enough energy to power the clock．Just refill the tank every few weeks, and this clock will keep on
ticking.Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier．(The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine．Then a rocket fires up, pushing the SSC past 1,000 miles an hour．In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle.
You"re having a blast at your friend"s birthday party．But when it"s time to bring out the cake, everyone crowds around, blocking your view．No worries．Throw the Triops into the air, and this clever camera captures the view from above．The Triops can take three pictures at once, each from different angles．You can also record sounds and command the Triops to start shooting whenever it hears that noise．That"s one smart camera.

The GPS Child Locator, or num8, attaches securely to a child’s wrist and contains a Global Positioning System (GPS), said Matthe
w Salmon, a spokesman for the manufacturer, lok8u."It uses GPS and GSM (Global System for Mobiles) technology with an accuracy of 10 feet (three meters)," he said. "It tracks your child."
"It only starts working when the device is
connected to the child’s wrist," Salmon said, and is "very difficult to get off.""Even if the child managed to get it off it would send an emergency text message through to your mobile phone," he said. "It would give you a Google Maps image with their exact location, the street name and the zip code."
When a child is wearing the device, a parent sends the text message "wru" and the chi
ld’s current location is sent back to a mobile phone or computer.Parents can also log on to the company website to discover their child’s present location.
"You can also set up a perimeter, an invisible fence, and if they wander out of this invisible fence which you put on the Internet it will warn you," Salmon said. "It will text you immediately."
Salmon said the device is waterproof and shockproof and lasts for three days with a full charge.
It will be available in both Britain and the United States this year and retails for 200 dollars with a 10 dollar a month subscription fee.
He said the company had received thousands of inquiries about the device since launching it this week. "Fifty percent are positive, 50 percent are negative, that it’s a bit Big Brotherish," he said. "But it’s really just about letting you have freedom of mind."
小题1:Only when does the device begin to work.
| A．it uses GPS and GSM technology | B．it is put within about 3 meters |
| C．it’s joined to parents’ computer | D．it is fastened to the child’s wrist |
| A．sending the text message “wru” | B．replying to the text message |
| C．getting a Google Maps picture | D．phoning the local police station |
| A．It won’t be easily found if a child loses t11e device |
| B．The device won’t work while a child is swimming |
| C．Parents can easily track children due to the device |
| D．The new product needs to be fully charged daily |
| A．explain how to use the new device |
| B．attract more buyers to the new product |
| C．discuss advantages of a new invention |
| D．introduce a new electronic equipment |
If you look for a book as a present for a child. You will be spoiled for choice even in a year when there is no new Harry Patten J.K Rowling’s wizard is not alone: the past decade has been a harvest for good children’s books ,which has set off a large quantity of films and in turn led to increased sales of classics such as The Lord of the Rings.
Yet despite that ,reading is increasingly unpopular among children .According to statistics, in 1997 23% said they didn’t like reading at all . In 2003, 35% did . And around 6% of children leave primary school each year unable to read properly.
Maybe the decline is caused by the increasing availability of computer games. Maybe the books boom has affected only the top of the educational pile . Either way , Chancellor Cordon Brown plans to change things for the bottom of the class .In his pre-budget report , he announced the national project of Reading Recovery to help the children struggling most.
Reading Recovery is aimed at six-year-olds ,who receive four months of individual daily half-hour classes with a specially trained teacher . An evaluation earlier this year reported that children on the scheme made 20 months’ progress in just one year, whereas similarly weak readers without special help made just five months’ progress ,and so ended the year even further below the level expected for their age.
International research tends to find that when British children leave primary school they read well ,but read less often for fun than those elsewhere .Reading for fun matters because children who are keen on reading can expect lifelong pleasure and loving books is an excellent indicator of future educational success . According to the OECD, being a regular and enthusiastic reader is of great advantage.
46.Which of the following is true of Paragraph 1?
A.Many children’s books have been adapted from films.
B.Many high-quality children’s books have been published .
C.The sales of classics have led to the popularity of films.
D.The sales of presents for children have increased.
47.Statistics suggested that _______.
A.the number of top students increased with the use of computers
B.a decreasing number of children showed interest in reading
C.a minority of primacy school children read properly
D.a large percentage of children read regularly
48.What do we know about Reading Recovery?
A.An evaluation of it will be made sometime this year.
B.Weak readers on the project were the most hardworking.
C.It aims to train special teachers to help children with reading.
D.Children on the project showed noticeable progress in reading.
49.Reading for fun is important because book-loving children _________.
A.take greater advantage of the project B.show the potential to enjoy a long life
C.are likely to succeed in their education. D.would make excellent future researchers
50.The aim of this text would probably be _________.
A.to overcome primary school pupils reading difficulty.
