Each of the passages is followed by 5 questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. choose the best one according to what you read. Passage OneFor years, many people would not believe that smoking could do harm to so many parts of the body in so many ways, study shows, however, that tobacco isnt one single thing. At least60%of it is gas. And one of these is the deadly carbon monoxide(CO).In factories, the amount of this gas in the air is measured, and it must be kept under fixed, safe level. But there is 640 times this safe amount in cigarette smoking.Oxygen is carried through your body by the red blood cells before the oxygen can. So, if you smoke your blood carries five to ten times more of this deadly gas than is normal. To make up for this, your body must make more red cells.The oxygen in your blood passes into your tissues(组织).But here again CO means trouble. It keeps the oxygen from passing into your tissues as fast as it should. Because of this, anyone who smokes and lives at the altitude(高度)of sea level may get as little oxygen as a non-smoker at an altitude of nearly two miles.This happens to every one who smokes, no matter how old or how young. Anyone who takes part in sports can tell you that those who smoke run out of breath more quickly than those who do not.1. Decide which of the following statements is true according to the passage.A.

Instead of using fingerprints or following suspects, government agents painstakingly sort out the mess of numbers and symbols and letters that can lead them back through the computer system to the cybercriminals.One such investigation led to the arrest of the man accused of sending the extremely dangerous Melissa virus, a computer virus that destroyed files in computers around the world in the spring of 1999. The agents received help from online service technicians, software experts, and a computer-science student. All helped to trace the complex pathways of the virus aback to the telephone line and computer of the man who released it.In another case, agents worked for two years to catch a cybercriminal who was, among other offenses, stealing credit card numbers. Agents found him by tracing a path from a computer he broke into to the mobile telephone he had used, which led to his address and arrest.The government agents are also working to block cybercriminals who could cut off power and confuse telephone companies. “Think of the consequences if the power went out for a week not in just one town or city but down the whole East Coast, says Michael Vatis, an FBI agent. From TVs to hospital equipment, all would fail.Makaveli and Tooshort were arrested for the charges of breaking into computers.

Windes cause the waves ,and the gravitational pull of the moon and the sun causes the tides. In places like the Bay of Fundy in Canada, the difference between the high and low tide level can be as much as 40 feet.France and Britain are now trying to use energy in the tides to produce electricity. Waves can produce electricity and some experiments are taking place to learn more about this. One of the most encouraging areas of research uses the difference between the temperature of seawater at the surface and deep down to produce electricity.11.One of the values of seawater is that_.A. it has no plants in it.B .it pulls the sun and the moon C. it flows all the timeD. it feeds all the time12.Waves and tides are caused by_.A. the same forcesB. different forcesC. their own movementsD. plants and animals13.According to the passage, which of the following statements is not true?A.
