Dinosaurs ruled the planet for millions of years, and they are generally believed to have gone extinct.But the reality is that modern versions of dinosaurs are all around us. Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.
The connections between birds and dinosaurs are explored in a new museum exhibit called Dinosaurs Among Us at the American Museum of Natural History in New York City.
According to Mark Norell, the director of the exhibit and an expert at the museum, it is based on new scientific evidence collected over the last two decades. "I think this is really going to shake up the way people think of dinosaurs “ Norell told reporters.” One could argue that we still live in the age of dinosaurs."
The exhibit includes ancient fossils and lifelike models of dinosaurs of all sizes to show the evolution of dinosaurs into birds. It examines several properties that are shared between the two species, including feathers, complex brains, the shapes. And sizes of eggs, and the ability to fly. Birds today make nests, lay eggs and tend to babies. Fossil research shows that some dinosaurs also made nests and laid eggs. Also,birds have hollow(中空的)bones, which don’t weigh much and allow birds to take more air into their lungs. These adaptations help with flight. Some dinosaurs had these properties as well. In addition, the exhibit shows that there are many similarities between the legs, claws; and feet of dinosaurs and birds.
Norell noted that the research behind this exhibit is the result of advanced scientific, techniques; and new technologies. For example researchers used a scanning (扫描) process called computed tomography (CT) to look inside the brains of extinct dinosaurs. It combines with many X-rays to produce a 3D image. "Modern technology tells us more than we thought
we could ever know about the connections between dinosaurs and birds," Norell said.

Sharks have lived in the oceans for over 450 million years, long before dinosaurs appeared. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely.
Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which sells for as much as $50 a bowl in fine Hong Kong restaurants. Other sharks are killed for sport and out of fear. Sharks are vulnerable(易受伤的) to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring(后代).
Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of shark injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine(海洋的) mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits.
If you are a typical ocean-goer, your chances of being killed by an unprovoked(非受挑衅而发生的)attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than a shark and thousands of times more likely to get killed when you drive a car.
Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria, and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.
Sharks are among the few animals in the world that almost never get cancer and eye cataracts(白内障). Understanding why can help us improve human health. Chemicals taken from shark cartilage(软骨)have killed cancerous tumors in laboratory animals, research that someday could help prolong your life.
Sharks are needed in the world’s ocean ecosystems. Although they don’t need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.
1.Which of the following is NOT a reason why people kill sharks?
A.People kill sharks for food.
B.People kill sharks for sport.
C.People kill sharks out of fear.
D.People kill sharks because they often attack swimmers.
2.According to the passage, which of the following statements is NOT true?
A.There are many different species of sharks, but only a few of them are dangerous to humans.
B.Sharks never get ill.
C.Sharks are a valuable resource for human.
D.Sharks play an important role in the ocean ecosystem.
3.It can be inferred from the passage that _______.
A.movies have given people the wrong impression of sharks
B.most sharks are dangerous to humans
C.sharks will attack anyone who is wearing black
D.it is dangerous to swim in the ocean
4.The underlined word “prolong” in the last but one paragraph means ______.
A.save B.protect C.lengthen D.improve
5.The best title for the passage would be _______.
A.Are Sharks Dangerous? B.Sharks And Humans
C.Sharks: Humans’ Friends D.Sharks Help Save Human Lives

London has more than nine million visitors every year. They come and visit some of the most famous places in England: Big Ben, the Tower of London and the River Thames.
You can see some of the most interesting places in London by getting on the tour buses. Or you can take a ride on the London Eye. This large wheel slowly takes you 135m above the River Thames.
The River Thames is London’s main waterway. It has shaped the capital’s landscape, history and geography. So one of the best ways of knowing more about the city is to take a trip along the river.
The clock tower of the Houses of Parliament, Big Ben, has become one of the main symbols of London. The sound of the bell, which you can hear at the beginning of many television and radio programmes, has become well-known throughout the nation.
No visit to London is complete without a look at the Tower of London, in the eastern part of the city. After Big Ben, the Tower may be London’s most visited tourist spot. Directly south is Tower Bridge, which is more than100 years old.
Along all the palaces in London, Buckingham Palace is the most famous. It has been the main London home of the royal family since Queen Victoria moved there in 1873. You can visit some of the rooms in August and September. And most mornings of the year you can watch the soldiers
outside changing the guard.
About one hour by train out of London is the Tower of Windsor. Here you can visit another of the Queen’s homes-Windsor Castle. There was a fire in 1992 and many of the rooms were badly burned. But now they are full of beautiful pictures, tables and chairs again.
Sightseeing in London is great, but it can get very tiring. So, the best way to start the day is to fill up with an English breakfast.
You can buy an English breakfast in nearly every hotel, and at many restaurants and cafes. An English pub is a good place to stop for lunch and a drink. You can get hot or cold food and try one of England’s many ales(浓啤酒). Fish and chips are also a traditional English meal. So look out for fish and chip shops in cities as well as by the sea.

Temples have existed for thousands of years. They are the proof of cultures and civilization that existed many years ago.
Gobekli Tepe, Turkey
Located on a hilltop in southwestern Turkey where it snows a lot in winter, the Gobekli Tepe is considered the world’s oldest temple. It is nearly 11,000 years old. There are carvings on the rock statues, mainly of lions, foxes, snakes, cranes and wild ducks, as well as scenes of people hunting. Because heavy snow makes it hard to get to the top of the hill, visitors are not recommended to go there in winters.
White Temple, Thailand
Immediately upon entering White Temple, you will realize this contemporary, unconventional temple stands out, even in a country dotted with temples. The White Temple is incredibly different and unique in its architecture, art and design. In fact, it is designed in a very modern way. This temple is all white. It is very hot in summer in Thailand, so going to White Temple in other three seasons is a wise choice.
Sagrada Familia, Spain
This symbolic Barcelona building is famously unfinished. It is said to be finished by 2026, but no body believes it. However, visitors believe its incompleteness is part of its charm, which sets it apart from other temples in the world. You will have to wait in a long line if you visit Sagrada Familia in summer holiday. Visitors are not that many in spring and winter.
Kinkaku-ji, Japan
This temple is absolutely the most popular one in Japan. Whether you visit during the fall when there are red leaves against the golden wall, in winter when the gold is topped with pure white snow, in spring with cherry blossoms, or in summer allowing you to smell the earthy smell after rain – there is never a bad time to visit this beautiful temple.
1.Which temple will you choose to go if you are a fan of modern architecture?
A. Gobekli Tepe. B. White Temple.
C. Sagrada Familia. D. Kinkaku-ji.
2.What makes Sagrada Familia special according to the passage?
A. It is unfinished. B. It is all white.
C. It is the oldest temple. D. It is untraditional.
3.Which temple is favorable to go all year round?
A. Gobekli Tepe. B. White Temple.
C. Sagrada Familia. D. Kinkaku-ji.

Dinosaurs 1. (doubt) ruled the land and sky in their time, but there was little evidence of their presence in water until now. According to a new study published in the journal Nature, 2. international team of researchers uncovered a well-preserved skeleton (骨架) of a dinosaur’s tail in 3. is now known as the Saharan desert – a region 4. (believe) to have been an oasis (绿洲) 100 million years ago.
The remains belong to a dinosaur species named Spinosaurus aegyptiacus. Through reconstruction 5. the tail skeleton, scientists found that the tail had a fin-like (鳍状的) shape, 6. propelled(推进) the dinosaur forward.
