江西省临川一中2019届高三下学期英语第二次联考试卷

阅读理解

    You've got your fancy new suitcase and you're ready to take it with you on your travels across the globe.

    You get to the airport, quickly moving through the crowds on the uneven pavement, rushing to check in. Then, your heart sinks when you realize your new suitcase has got a serious case of the wobbles (摇晃).

    Why does this happen?

    Scientists from the Universite Paris-Diderot in France investigated this matter and published their findings in the science journal Proceedings of the Royal Society A. They also suggested some solutions to overcome this modern-day problem.

    To learn more about the issue, they put a suitcase on a treadmill (跑步机) and observed what happened.

    It was soon noted that the "wobble" was actually a result of repeated actions that caused the suitcase to sway from side to side. They discovered that if one of the wheels encountered an obstacle such as a small bump, it jumped into the air for just a moment and then banged back down to the ground. That second action caused the opposite wheel to lift off the ground and then to bang back down, causing the first to lift again and so on. This swaying increased as the luggage was pulled along.

    "The suitcase is a fun way to tackle the problem, but the study would be the same for any trolley with two wheels or blades (桨叶)," Sylvain Courrech du Pont, lead author of the study, told BBC News. "So it will be the same for a caravan (大篷车) or maybe also for airplanes."

    Instead of slowing down when we see a rocky part of the path, the scientists recommended doing the exact opposite and speeding up. This is because going faster gives the wheels less time to rise and fall, preventing the case from swaying. They also said that reducing the angle of the suitcase by lowering its handle to the ground would help keep it steady.

    "These findings could help researchers simulate and design better rolling suitcases and other pulled trolleys, such as towed trailers," Courrech du Pont added.

With these masterminds (智者) working on perfecting our suitcase problems, wobbly luggage may soon be a thing of history, leaving us to enjoy our travels.

(1)、The main purpose of the first two paragraphs is to ______.
A、show the importance of a good wheeled suitcase for travel B、lead up to the wobbling problem of wheeled suitcases C、describe how unstable wheeled suitcases can be D、show that wobbling can cause wheeled suitcases to stop working
(2)、According to the scientists, when a suitcase meets with an obstacle, ______.
A、the swaying will stop for a moment B、its two wheels will jump into the air at the same time C、even a small obstacle can lead to a serious damage D、there is a series of repeated actions leading to the swaying
(3)、What can be done to keep a suitcase steady on an uneven path according to the text?
A、Slow down. B、Pull the suitcase at a faster speed. C、Raise the handle of the suitcase. D、Increase the angle of the suitcase.
(4)、According to the article, the findings could ______.
A、help improve the design of suitcases B、solve the wobble of suitcases completely C、be helpful in the advancement of treadmills D、be used to develop blades for boats

    Diana Ross, American pop singer and actress, achieved international popularity, first as the leader singer of the Supremes and later as a solo(独唱的) artist. Diana Ross was born on March 26, 1944, in Detroit, Michigan. She was the second of six children of Fred and Ernestine Ross, who lived in one of Detroit's poor districts. Because her family were closely connected with each other, Ross almost didn't notice the difficult life as she grew up.

    Ross professional career began in 1959, when she joined several neighborhood friends to form the Primettes. The group was renamed the Supremes after signing a recording contract (合同) with Motown late the following year. The group produced many number-one hit singles (热门单曲) on the US Billboard hot 100, including Baby Love, Stop! In The Name of Love and Someday We Will Be Together. In 1967, the group was renamed Diana Ross and the Supremes, foreshadowing(预示) Ross' solo career, which she started in 1970.

    Beginning with Ain't No Mountain High Enough from her first solo album, Ross enjoyed more than ten years of great success with her hit singles. Ross also developed a film-acting career in the 1970s, beginning with a starring role as blues singer Billie Holiday in Lady Sings the Blues and continuing with Mahogany, for which she also recorded the theme song Do You Know Where You're Going To.

    However, in the mid-1980s, Ross saw her career begin to wane. Most of her albums were re-recordings of earlier material. In 2006, she produced I Love You, a collection of love songs by many artists, and she started an energetic concert tour the following year to make the album publicly known. Although you can't find her songs on the US Billboard Hot 100 now, Ross remains popular as one of the leading musical performers of all time.

    One of the latest trends(趋势) in American Childcare is Chinese au pairs. Au Pair in Stamford, Conn, for example, has got increasing numbers of request for Chinese au pairs from aero to around 4, 000 since 2004. And that's true all across the country.

    "I thought it would be useful for him to learn Chinese at an early age" Joseph Stocke, the managing director of a company, says of his 2-year old son. "I would at least like to give him the chance to use the language in the future, " After only six months of being cared by 25-year-old woman from China, the boy can already understand basic Chinese daily expressions, his dad says.

    Li Drake, a Chinese native raising two children in Minnesota with an American husband, had another reason for looking for an au pair from China. She didn't want her children to miss out on their roots. " Because I am Chinese, my husband and I wanted the children to keep exposed to(接触) the language and culture." she says.

    "Staying with a native speaker is better for children than simply sitting in a classroom," says Suzanne Flynn, a professor in language education of Children. "But parents must understand that just one year with au pair is unlikely to produce wonders. Complete mastery demands continued learning until the age of 10 or 12. "

    The popularity if au pairs from China has been strengthened by the increasing numbers of American parents who want their children who want their children to learn Chinese. It is expected that American demand for au pairs will continue to rise in the next few years.
