33、a.This was the second day of the search and the police were now very worried about the safety of the three missing people.The police said that the search had covered a wide area, but the rainforest was thick and their work was made harder by the recent rain. Later on Chief Inspector (警官) Roger Fleet

34、 said, “The travellers had a radio with them. If they had been in trouble, they would have called us.”The three travellers left Cooktown very early on Saturday morning in a Toyota car. They took a small dirt road that runs down to the Daintree River, a dangerous river full of crocodiles (鳄鱼). Chief

35、Inspector Roger Fleet said the tourists wouldnt have got into trouble if they had stayed on the main road.A photo of Vicky and Tom was found by a policeman under the “Be Careful about crocodiles” sign near the river. Why was the photo left behind? This is just one of the unanswered questions. Other

36、questions are: Why was the photo left behind? Why was the Toyota parked and locked at the edge of the rainforest? The police said that the travelers had left a map of the area behind. Why? Why had someone drawn a cross on the point (地点) where the car is? Is this a sign? What does it mean? If anyone

Theres only one place, and thats Hollywood, in California. The scenes you see

40、from the tourist train are film sets（布景） in the Universal Studios, one of the oldest and largest movie companies(公司) in the USA.A visit to Universal Studios brings back memories of great days of Hollywood, the films and the stars.

41、to be. Costs have gone up and confidence has gone down. Movie-makers are afraid to spend their money on expensive new ideas. Instead, they repeat old ones.The film industry is changing fast. Teenagers still go out to the movies. The theatre is a good place to meet friends away from home. But older p

42、eople mostly stay home to watch series, like Dynasty have become as important to Hollywood as expensive movies. These “soap opera”, as they are called, show rich, powerful families living in beautiful homes and wearing beautiful clothes. But the actors and actresses are nearly all middle-aged, like

43、many of the people who watch them.Though it is soap operas that are keeping the film-makers of Hollywood in Business, big films are still being made in America. But more and more of them are made outside Hollywood. New York is the most important new center, but there are many others as well. Movie-m

44、akers have realized that they dont need Hollywood any more. Modern cameras and real houses instead of expensively made copies in a studio.

48、re less attractive. D. They are cheaper and easier to make.CA new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increase the risk. Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the

49、 association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanomaMost health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin

50、cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.The researchers said that among the pr

51、oblems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancerpeople with fair skin(白皙的肤色) and freckles (雀斑), for exampleare more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.The studies

52、, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.43.
