The World Bank has looked at the distinguishing features of successful school system.
According to the World Bank’s education specialist, Harry Patrinos, this include: improving the quality of teachers and making sure that teachers are highly regarded; providing information to make schools accountable and giving autonomy to schools and head teachers.
This matters not only for individual pupils but also for the well-being of countries, he says, because improving educational performance has a direct impact on improving economic performance.
China’s education performance— at least in cities such as Shanghai and Hong Kong— seems to be as spectacular as the country’s fast growing economy.
Certainly both these open and outward-looking cities consider education to be important and are willing to adopt the best educational practices from around the world to ensure success. In Hong Kong, education accounts for more than one-fifth of entire government spending every year.
“Shanghai and Hong Kong are small education systems, with a concentration of ideas, manpower and resources for education,” says Prof Cheng.
Under the banner “First class city, first class education”, Shanghai set about systematically re-equipping classroom, upgrading schools and improving the curriculum in the last decade.
It got rid of the “key schools” system which concentrated resources only on top students and top schools. Instead staff were trained in more interactive teaching methods and computers were brought in.
About 80% of Shanghai school leavers go to university compared to an overall average of 24% in China.
Meanwhile, dynamic Hong Kong was forced into educational improvements as its industries moved to cheaper mainland Chinese areas in the 1990s.Its survival as a service and management hub depends on upgrading knowledge and skills.
In the last decade Hong Kong has concentrated on closing the gap for all students, says a report by McKinsey management consultants.
The report, How the World’s Most Improved School Systems Keep Getting Better, rated Hong Kong’s education system among the best in the world.
1.The World Bank’s survey about education mainly concentrates on .
A. what has made some education systems successful
B. China’s education system and competitive exams
C. how to relieve Chinese students of their heavy schoolwork
D. the relationship between education and economic development
2.According to Harry Patrinos, the key to successful school systems is .
A. to give autonomy to all teachers to educate students freely in class
B. to let students attend after-school tutoring and do more exercises
C. to improve teachers’ abilities and give schools free performance right
D. to make school education directly serve the economy of the country
3.We can learn from the text that .
A. the “key school” system is the key to many schools’ failure
B. students in Shanghai and Hong Kong work the hardest
C. Hong Kong’s educational performance isn’t as good as Shanghai’s
D. Shanghai and Hong Kong’s economic performance will improve
4.What is the author’s attitude towards the school systems of Shanghai and Hong Kong?
A. Negative. B. Positive.
C. Neutral. D. Critical.

Three Japanese tourists taking a holiday in Australia got stuck when their GPS told them they could drive from the mainland to an island, failing to mention the 15 kilometres of water and mud in between.
As they drove their hired car from Moreton Bay to nearby North Stradbroke Island, they started to notice the firm surface they were driving on giving way to the well-known bay mud. However, being confident that their GPS would direct them to a road soon, they decided to drive on, managing to travel around 500 metres before their car was up to its tires in mud. To make matters worse, the tide(潮汐) started to come in and soon forced them to seek help and abandon the vehicle. Just four hours later the car was trapped in two metres of water — to the great amusement of onlookers on the shore and passengers on passing boats and ferries.
Yuzu Noda, 21, said she was listening to the GPS and “it told us we could drive down there. It kept saying it would navigate(導(dǎo)航) us to a road. But we got stuck…there’s lots of mud.” She and her travel companions Tomonari Saeki, 22, and Keita Osada, 21, instead had to give up their plans for a day trip to the island and headed back to the Gold Coast of a lift from the RACQ tow truck(吊車) driver who was called to the trapped car. No such luck for the hired car though – after assessing the situation, no attempt was made to recover it. The students from Tokyo, who are due to return home tomorrow, said the experience would not put them off returning to Australia for another visit. Mr. Tomonari said, “It has rained every day on our six day holiday. Hopefully next time we come back it will be sunny.”
The car was covered by insurance, but the tourists will have to pay up to about $1500 in extra charges.
1.The three Japanese tourists got stuck because .
A. there was no way to the island

A. some onlookers went to save them
B. they got stuck in the mud

D. they managed to travel around 500 metres
3.How did these Japanese students get back?
A. They had to walk back to their living place.
B. They had to take a lift from the tow truck driver.
C. They had to repair their GPS and drove back.
D. They had to turn to passengers on boats and ferries.
4.According to the passage, which of the following is true?
