These reptiles are excellent predators (肉食动物) and have few natural enemies. Crocodiles have about 30 or 40 teeth in each jaw. And it is the jaw that gives a unique feature to them. A crocodile can close its jaws with such force that it can break the bones of some animals. Yet, once the jaws are shut, they’re so weak that they can be held together by a person’s hand. To reproduce, crocodiles, like other reptiles, lay eggs. One female can produce between 20 and 90 eggs at a time. Once laid, female crocodiles bury their eggs in sand or mud, where they are left to hatch. Some females stay in the area to protect the nest and look after the young after they hatch, but often other predators eat the eggs. 59.

It was based on the music called rhythm and blues that was performed by African American musicians. Early rock and roll singers developed their own kinds of music. Elvis Presley, Chuck Berry, the Beach Boys, and Bob Dylan were the most popular rock and roll musicians in the early 1960’s. All were American. Then, in 1964, a new rock and roll group from England invaded America: the Beatles. Some people say the Beatles’ music shook America like an earthquake. The Beatles changed rock and roll forever. Their early songs were influenced by American rock and roll musicians, including Chuck Berry. But the Beatles looked different and sounded different from any musical group before them. The Beatles released their first album in the United States in 1964, when all of the top five records in America were by the Beatles. In 1967, they released an album called “Sergeant Pepper’s Lonely Hearts Club Band.” It was one of the first “concept” albums. That is, all the songs were linked by a common story or idea. The popularity of the Beatles led the way for more rock and roll bands from England to become popular in America. The Rolling Stones was the most important of these bands. The Rolling Stones is one of the few groups from the 1960’s that is still performing and recording today. In 1965, the group recorded one of its most famous songs, “Satisfaction”. The musical instrument most linked to rock and roll is the guitar. Experts say Jimi Hendrix was one of the most influential guitar players in rock and roll during the late 1960’s. His “Purple Haze” was liked by many people. By the 1970’s, rock and roll music became known as rock music. It expanded into many new forms. For example, there was country rock, hard rock, acid rock, and heavy metal rock. Punk rock, jazz rock, and glitter rock. In the middle 1970’s, experts say rock music regained some of the energy of early rock and roll. Bruce Springsteen and the E Street Band became popular with their album “Born to Run”. Springsteen’s music was like the lively rock and roll music of the early nineteen-sixties. Many of his songs were about social issues. He sang about the effects of unemployment and the war in Vietnam. 63. The main topic of this passage is _______.

Coroebus won the only event at the Olympics. This made him the very first Olympic champion in history. Then they grew and continued to be played every four years. In 393 AD, the Roman emperor Theodosius I, a Christian, announced to end the Games because of their pagan (异教的) influences. About 1,500 years later, a young Frenchman named Pierre de Coubertin began their revival (恢复). In 1892 Coubertin first brought forward his idea to revive the Olympic Games but failed. Two years later, Coubertin organized a meeting with 79 delegates (代表) who represented nine countries. At this meeting he got what he wanted. All the delegates at the con-ference voted for the Olympic Games. They also decided to have Coubertin set up an international committee to organize the Games. This committee became the International Olympic Committee (IOC) and Demetrious Vikelas from Greece was selected to be its first president. Athens was chosen for the revival of the Olympic Games and the planning was begun. (责任编辑：admin) |
