【简答题】
阅读下列短文,从每题所给的 A 、 B 、 C 和 D 四个选项中,选出最佳选项,并在答题卡上将该项涂黑。 A At 11:38 am on August 8th, exactly 50 years since the Beatles were photographed walking across a suburban London zebra crossing, hundreds of fans from around the world gathered on the same street where the original 1969 picture was taken. Wearing sixties get-ups, parading Beatles hits, they were eager to celebrate the historical moment and recreate the image, and did not mind if they looked somewhat out of place in 2019. Fifty years ago, the photo became the cover of the band’s final album “Abbey Road”, unknowingly creating what would become one of the most popular images in music history. Abbey Road, a fairly common street, is just a stone’s throw from the studio where the album was recorded. The crossing has since become a famous place for devoted fans attempting to take the cover picture themselves, causing traffic jams from time to time. The original was probably shot on a square format Hasselblad, "and you'd need to be a mathematician to work out all the details," Dunham says. An average person will want a wide-angle lens (镜头), at least 24-millimetre, for a DSLR. Point-and-shoot cameras and smartphones can do the job, though not if you want a serious print for others. The original was shot from the low position, though a solid box can get you high enough to ensure your subjects don't block where the road meets the horizon. "A Hail Mary shot (holding the camera high above your head) will do if you're tall," Dunham says. "Oh, and make sure your battery is charged and in the camera," he adds with a smile. One American fan on the spot also said that many had made the journey because Abbey Road is one of the very few remaining physical memorials to the band. The anniversary event highlights how relevant the Beatles are today for people of all ages, due to their down-to-earth identity and marvelous musical talent. 1. What does the underlined phrase “a stone’s throw” mean in this passage? A. a remote place B. a short distance C. a hard stone D. a well-aimed throw 2. What do we know about Abbey Road? A. Hundreds of people gathered on Abbey Road in 1969. B. The picture of Abbey Road became the cover of the Beatles’ first album. C. Demanding technique was probably needed for the original Abbey Road picture. D. Abbey Road has become the most popular physical memorial for the fans of the Beatles. 3. What can we infer from the last paragraph? A. The Beatles became famous because of their musical talent. B. People who work hard are more likely to listen to the Beatles. C. The Beatles are still appealing to people at different ages today. D. Most of the Beatles fans make the journey to Abbey Road every year.
