1 Toyota Motor Corp, Japan’s biggest carmaker, said on Friday it will recall 1,489 Lexus sedans (高级轿车) sold in China. "It will take us some time to ship the fuel tanks and vent pipes to China to change those in these Lexus sedans for customers free of charge, if problems are found," said Yang Hongjian, a spokes- woman of Toyota’s China representative office. The expected recall will affect Lexus LS430 sedans made in Japan from July 29, 2003 to January 14, 2004, the representative office said in a statement. Toyota has not received complaints from Chinese customers, according to the statement. The move will be part of Toyota’s global recall of 18,200 Lexus LS430s. It will be the third car recall in China in two weeks. Although automobile recall is a common practice in developed markets, it remains new to Chinese customers. The Chinese government published long-awaited automobile recall rules on March 15, which will be officially carried out at the beginning of October. China’s auto market is forecast to reach 10 million units by 2010. Automakers, especially Chinese producers, will face greater pressure from automobile recalls, which could be very costly sometimes, and should be in full preparations, according to the expert. The Japanese carmaker sold 1, 549 Lexus vehicles on the Chinese mainland during the first five months of this year, according to Yang. Lexus sales on the mainland reached 4,000 units last year, up from 1,600 units in 2002. (China Daily July 3, 2004) 1. What can we learn from the text? A.

9 Across the globe, single parent homes are on the rise. In the US, the 2000 census (人口普查) showed 24.8 million, or nearly 24 percent of the nation’s 105.5 million households, were traditional two-parent homes. By comparison, 9.8 million households, or 9 percent of all US households were headed by an adult raising a child alone. The 1990 census showed 26 percent of homes were led by a married mother and father, and 8 percent of homes were led by a single parent. Similar increases occurred in other countries. In the UK, lone-parent homes increased from 3.3 percent in 1990 to 5.5 percent in 1999. Single parent households in Australia rose from 5.8 percent in 1990 to 7.6 percent in 1999. Belgium saw the increase from 1.8 percent to 2.7 percent during the same period of time. These countries tend to have greater acceptance of the single parent because there are fewer nearby family members to disapprove, Riche, a Census Bureau director, said. Just as in the US, those changes raised new questions about how involved govenment should be in helping single parent families. Some research suggests children raised in two-parent families are better off than those who depend on one. “The position of one-parent families in any country is very much a gender (性别) issue-women’s opportunities, especially working-class women on low income,” said Sue Cohen, coordinator (协调员) of the Single Action Parents Network in England. 5.Not considering the exact number of the single-parent families, which country saw the fastest rise rate in 1999, compared with 1990? A.UK. B.Australia. C.America. D.Belgium. 6.What is the cause of the rise of single parent families across the globe? A.The nearby family members have a favourable opinion. B.A lone parent is well off enough to support his /her children. C.A lot of problems have arisen in two-parent families. D.We cannot get enough proving information from the text. 7.Which of the following is TRUE about the increase of single parent families according to the passage? A.It will somewhat limit the growing population of younger generation. B.Governments should take actions about the social problems brought about by it. C.Single parent families are not looked down upon in any country mentioned here. D.Generally speaking, the single parents needn’t worry since they are highly paid. 8.Which of the following diagrams correctly shows the rise of single parent families in the US from 1990 to 2000?
