[A] Sports fans often imagine what would happen if two successful players from different times competed against each other. In boxing, who would win if a young Muhammad Ali were up against a young Mike Tyson? In golf, who would score better if Jack Nicklaus faced Tiger Woods? [B] Paleontologists - scientists who study fossils - like to play the same game with dinosaurs. Who would win a fight between a Tyrannosaurus rex (T. rex) and a Spinosaurus? These are two unbelievably powerful dinosaurs that never faced each other in real life. This is because the Spinosaurus lived almost 10 million years before the T. rex. The movie Jurassic Park III attempts to answer this question. After a bloody battle, the Spinosaurus eventually wins the match by breaking the neck of the T. rex. [C] For people who are not dinosaur experts, this result might be unexpected. Most people learn from a young age that the T. rex was the most dangerous and fearsome dinosaur. However, dinosaur experts are beginning to give the Spinosaurus more credit. One reason for this is because detailed information about the Spinosaurus has only been collected in the last few decades. [D] In 1914, the German paleontologist Stromer von Reichenbach first discovered some important parts of the dinosaur. These included several large spines that were clearly used to support a giant sail on the dinosaur's back. Stromer thus gave this new dinosaur the name "Spinosaurus." Until 1944, the fossils were displayed at a Munich museum. However, when Munich was bombed during World War II, all of Stromer's fossils were destroyed. For more than 50 years, very little new information about the Spinosaurus was discovered. [E] In the early 21st century, however, large sets of Spinosaurus fossils were found. As a result, we now have much more information about this amazing creature. Scientists now know that this extremely large dinosaur was almost 15 meters long and larger than the T. rex. Scientists have also learned that the Spinosaurus had many wonderful talents. One of these was its impressive swimming ability. It was also one of the only dinosaurs that could travel both on land and in water. [F] Because of its size and talent, the Spinosaurus might win another battle with the T. rex - the battle for the most interesting dinosaur. In 50 more years, the Spinosaurus might just become the world's most popular dinosaur.unbelievably
DIRECTIONS: Chооse the cоrrect аnswer for eаch question.Aiming High [A] Yuri Gаgarin had worked hard all of his life. He had often told himself that one day his efforts would lead to something special. Sitting in a spacecraft, minutes away from being rocketed miles above the Earth, he realized that he would soon have the most special experience anyone could imagine. Yuri Gagarin was about to become the first man to visit space. [B] Gagarin was born on March 9, 1934 in the Soviet Union (present-day Russia). He grew up in a very ordinary family. His father was a carpenter,1 and his mother was a milkmaid.2 The young Gagarin, however, had bigger dreams. He studied very hard in his early school days and received scholarships to study at a technological academy.[C] Gagarin's real intention, however, was to become a pilot. While he was studying at the academy, he volunteered as a junior member of a local flying club. Eventually, after countless weekends, he learned to fly. Because of his incredible focus and attention to detail, he became a very good pilot. [D] For other young Soviet men, being called into the national armed forces was a scary moment. This was not the case for Gagarin. This was because it gave him the chance to improve his piloting skills as a member of the air force. Gagarin did more than simply improve. Over time, associates in the air force considered him to be one of the best pilots in the entire country.[E] When the Soviet Union commenced its space program in the late 1950s, Gagarin was included in a list of 20 possible astronauts for the country's, and the world's, first space flight. Those in senior positions at the space program admired Gagarin for the incredible amount of work he did in training. Psychologists3 also perceived that he had the right state of mind to be sent into space. As a result, Gagarin was chosen for the mission.[F] When his Vostok spacecraft lifted off on April 12, 1961, Gagarin could not hide his excitement. Although he did not usually speak in an informal way, he shouted "Poyekhali!" ("Let's go!") as the rocket sent him into space. After making one full orbit4 of the Earth, Gagarin landed safely and immediately became a hero in his country. Sadly, Gagarin died in a plane crash in March 1968. However, more than 50 years after his flight to space, people around the world still admire him for his bravery.1 A carpenter is someone who makes things from wood.2 A milkmaid is a term used in the past to describe a woman who gets milk from cows on a farm. 3 A psychologist is someone who studies the human mind. 4 An orbit is the path taken by an object around another object in space. In paragraph B, the word academy means ________.
DIRECTIONS: Chооse the best аnswer fоr eаch question. Sextuplets [A] Most of us hаve met a pair of twins or triplets once or twice in our lives. But how many people know a set of sextuplets: six children born at the same time to the same mother? Not very many of us have. This is why the Dilley family is so famous.[B] Keith and Becki Dilley got married in 1986 and wanted to have children right away. After five years of no children, doctors gave Becki a special medication to help her get pregnant. It worked! But Becki wasn't pregnant with just one baby. She was pregnant with five - or that's what the doctors thought at first. [C] On May 25, 1993, Becki went to the hospital to give birth. The doctor delivered five healthy babies before Becki felt a sixth set of feet. The last Dilley baby, the sixth one, was quite a surprise. The babies had to stay in the hospital for several months. Some of them needed special machines to help them breathe. Others were so small and fragile that Becki and Keith could not hold them. After three months, the babies were finally able to go home.[D] Life in the Dilley household was quite busy, as anyone can imagine. There were six diapers to change, six bottles to prepare, six tiny outfits to wash, and so on. Thankfully, the Dilleys had family nearby who could help carry the load. Grandparents, aunts, and uncles all pitched in to help.[E] The sextuplets are grown up now. They have families of their own and work at various jobs. They seem to be just like other young adult, but they always have an amazing story to tell.Who does the word they refer to in the second sentence of the final paragraph?
