Reading comprehension.

     Even at school there had been an unhealthy competition between George and Richard.

     "I'll be the first millionaire in Coleford!" Richard used to boast.

     "And you'll be sorry you knew me," George would reply "because I'll be the best lawyer in town!"

     George never did become a lawyer and Richard never made any money. Instead both men opened

bookshops on opposite sides of Coleford High Street. It was hard to make money from books, which

made the competition between them worse.

     Now with only one bookshop in town, business was better for George. But sometimes he sat in his

narrow, old kitchen and gazed out of the dirty window, thinking about his former rival (竞争对手).

Perhaps he missed him?

     George was very interested in old dictionaries, He'd recently found a collector in Australia who was

selling a rare first edition. When the parcel arrived, the book was in perfect condition and George was

delighted. But while he was having lunch, George glanced at the photo in the newspaper that the book

had been wrapped in. He was astonished-the smiling face was older than he remembered but unmistakable!

Trembling, George started reading.

     "Bookends have bought ten bookstores from their rivals Dylans. The company, owned by multi-millionaire

Richard Pike, is now the largest bookseller in Australia."

Several southwestern provinces in China are now experiencing the worst drought(旱灾) since the 1950s. The drought has left 18 million people and 11 million farm animals in Yunnan, Guangxi, Sichuan and Chongqing without enough water supplies. And it has affected 5 million hectares of crops in the provinces.

According to China’s Meteorological Administration (中国气象局), the average daily temperature in Yunnan over the past six months has been two degrees higher than normal. And the province has had only half the rainfall of an ordinary year. In Qinglong county, Guizhou, there had been no rain for 268 days until March 25, when it finally rained for three hours.

To ensure the safety of drinking water, local governments have taken emergency action. Workers in parts of Yunnan are drilling (钻空) daily in the hope of digging 1035 wells by mid-May. Among them, 52 have already started working and 288 are under way, providing 20 percent of the required drinking water. Meanwhile, Yunnan province intends to send more migrants (农民工) to work outside the province as the drought worsens. This will not only help to deal with the drinking water shortages, but also increase those farmers’ income. The government will offer free skill training and organize job fairs.
