More than a hundred years ago, before the Civil War, a crew of cowboys stood outside a large horse corral, With them was their boss Bradford Grimes, a cattleman, who owned a large South Texas ranch near the Gulf of Mexico.
Just then, Mrs. Grimes, the cattleman’s wife, came to the ranch house door and cried out, "Bradford! Bradford! Those Blacks are worth a thousand dollars apiece. One might get killed." The cowboys laughed, but they knew she was telling the truth. For they were all Black slaves. Bradford Grimes was their owner.
Most of the first Black cowboys were slaves, brought by their masters from the old South. On the plantations in the South, the slaves cut cotton. On the ranches in Texas they had to learn a new trade—breaking horses and handling long-horns. Some were taught by Mexican vaqueros, some by Indiana who knew the ways of horses and cattle.
Grimes was only one of hundreds of slaveowning ranchers who ran cattle in Texas. The ranchers had brought their families and slaves from Mississippi, Georgia, and other southern states. They came on horseback, on foot, and in wagons.
Some ranchers settled near the Mexican border, but there they found that it was too easy for their slaves to escape. Even slaves as far north as Austin, the capital of Texas, came to think of Mexico as the promised land. As early as 1845, the year that Texas became a state, a Texas newspaper reported the escape of twenty-five Blacks. "They were mounted on some of the best horses that could be found, "the story said, "and several of them were well armed." Thousands of other Black slaves escaped in the same way.
All-Black cattle crews were common throughout central and eastern Texas. There were even a few free Blacks who owned ranches before the Civil War. Aaron Ashworth was one of them, and he owned 2500 cattle, as well as some slaves of his own. He employed a White schoolmaster to tutor his children. Black cowboys helped to tame and settle a wild country.
Since the author tells you that there were hundreds of slave-owning cattle ranchers in Texas, it is possible to say that ______.

A:Blacks didn’t help to settle Texas B:Blacks helped to settle Texas C:Blacks helped only sometimes to settle the new territory D:Blacks only helped to tame cattle

第二篇 　　 Declining Interest in Developing Foreign Language Skills 　　Australians’ foreign language skills are declining, Voice of America has reported. New figures show that only 13 percent of high school graduates can speak a foreign language. But four decades ago, 40 percent had foreign language skills. 　　Professor Elise Tipton, from the University of Sydney, says increasingly students do not feel the need to learn another language to boost their career. She believes that Australia’s economic boom, which is driven by red-hot demand for its minerals, is helping mask serious deficiencies (缺陷) in its language skills 　　Australia does business very successfully in English with most of its trading partners. But as the world’s economic power shifts to emerging regions such as Asia, its language gap could soon be exposed. According to the new figures, less than 6.5 percent of high school graduates are proficient in an Asian language. Academics worry that this means Australia will increasingly be isolated from its economically important Asian neighbors. Dilip Dutta, from the economics and business faculty at Sydney University, says language skills can enhance trading opportunities. If Australians want to trade with Asian countries, it is very important for them to learn the language that will help them to get closer to the culture. 　　But students have different opinions about Asian language learning. Pippa McCowage, a 22-year-old Australian student, says many young Australians have a half-hearted approach to foreign languages, and the language curriculum is often weak. "While we’re encouraged in high school to learn another language, it’s not really apparent to me as a realistic expectation that you will have to speak it," said McCowage. "For example, I learned Japanese in high school. When I went on an exchange in Year 10, I found that the Japanese students of my age had a much greater proficiency in English than I did in Japanese. So in that sense, it almost discourages you." 　　At present, about 70 percent of Australia’s major exports go to Asia and the Australian government has been keen on developing closer economic and diplomatic ties with Asia. Academics say that, as Asia becomes one of the world’s economic　powerhouses (经济体), Australia needs to improve its language skills if it is to take full advantage of the business opportunities on its doorstep. What does Dilip Dutta think language skills can do?

A:Improve your relation with your partner. B:Help settle international conflicts. C:Remove barriers in negotiations. D:Increase trading opportunities
