【題目】我們?nèi)粘Ｉ钆c地球自轉(zhuǎn)息息相關(guān)，在以下現(xiàn)象中離不開地球自轉(zhuǎn)的是（ ）

①日出而作，日落而息

②我們吃早餐時(shí)，給美國的朋友打電話要說：“晚上好”

③每天大家都讀書看報(bào)學(xué)習(xí)知識

A.①②③B.②③④C.①②④D.①②③④

【答案】C

【解析】

地球繞地軸自西向東不停轉(zhuǎn)動(dòng)，叫地球自轉(zhuǎn)，地球自轉(zhuǎn)產(chǎn)生的現(xiàn)象是晝夜交替、日月星辰東升西落和時(shí)間差異；地球在自轉(zhuǎn)的同時(shí)還要繞著太陽自西向東轉(zhuǎn)動(dòng)叫地球公轉(zhuǎn)，地球公轉(zhuǎn)產(chǎn)生了四季變化、正午太陽高度的變化、晝夜長短的變化以及地球五帶等現(xiàn)象。①日出而作，日落而息，是由于地球自轉(zhuǎn)產(chǎn)生的太陽的東升西落。②我們吃早餐時(shí)，給美國的朋友打電話要說“晚上好！”，是由于地球的自轉(zhuǎn)產(chǎn)生了時(shí)差。④北京人到新疆去開始很不適應(yīng)，原因很多，比如：在北京吃晚餐時(shí)，新疆太陽還老高，大家都還要工作．是由于地球自轉(zhuǎn)產(chǎn)生的時(shí)差，故本題選C。

【題目】Over a year ago, Liang Bo was just an ordinary college student studying music. Now, after nearly 80 days of competition, he has become “The Voice of China.”

The lucky young man was the winner of the first season of The Voice of China, the most popular TV talent show last summer. He captured(虜獲) the hearts of audience(觀眾) with his passionate(激情的) rock’n’roll performance at the show’s final on Sep.30, 2012.

Fans describe Liang’s voice as “natural, clear and touching.” Although he seems cool on stage, he can quickly turn on the power once he starts singing. “His performances make you imagine things. When I listen to his singing, I see pictures and think of stories.” said Na Ying, one of the four judges on the show. She was also Liang’s tutor for the competition.

The 21-year-old boy was born in Changchun, Jilin. Like many young Chinese, he fell in love with music through playing the guitar. Liang got his first guitar as a birthday gift when he was in the middle school. He would spend days and nights practicing. “I can’t live without my guitar,” he said.

“I don’t like talking much but I carry great passion inside me.” Liang said. There is no better way to let it out than through music like rock’n’roll. Many compare Liang to famous Chinese rockers including Xu Wei, Wang Feng and Zheng Jun. But the young man doesn’t want to stand in others’ shadow(陰影). “I respect those rockers, but I’m not going to copy them. I will be who I am.” he said.

【1】What was Liang Bo before the competition?

_________________________________

【2】How many judges are there in the TV talent show?

【4】Which was the most popular TV show in summer in 2012?
