【正文】 makes the management of cancer more difficult .Although for now there is no simple answer to why obesity increases a person39。8verage age was 57. By December 2021, 24% of the participants had died, just a quarter of them from cancers. In analyzing the results, researchers attempted to take account of such potential factors as smoking drinking alcohol, taking aspirin and a wide variety of other factors that might otherwise affect the results. The results are clear the more you weigh, the greater your risk of dying of cancer will be (up to 52% higher for men and 62% for women). In men as well as women, the only cancers that did not have a strong connection with weight were lung cancer andbrain cancer. For women, the strongest correlation with weight was uterine cancer(子宮癌）， which is times higher for women with a BMI(Body Mass Index)of 40 or more. For men, it was liver cancer, which is times higher in most obese（肥胖的） men. Smokers tend to be more successful in keeping weight off than nonsmokers ,slightly reducing the risk ,But many of them don39。s important to check our phones like checking a fire alarrn. 31 What does the author suggest we do about phantom phone vibration? A. We should always fully believe our own sense of listening. B. We should just check our phones whenever we think they39。s not too much trouble to do that, is it? 28. According to this passage, phantom phone vibration__________ . A. is mon among people with mental problems B. can measure people39。t deal with all that information all the time, Michael Rothberg, a researcher at Bay8tate Medical Center in Springfield , US, told Live Science. For example, the rU8ding (沙沙聲 ) of clothing or the growling c咕咕聲 ) of your stomach may both lead your brain to believe that they e from the vibration of your phone it is like trying to hear your name being called in a noisy mom. . So, perhaps you should just check your phone whenever you think it39。t our brains just make every judgment correctly without being too sensitive to false signals? . The answer is that your brain bears a heavy burden every day. . You get a large amount of . sensory information that39。s a small price to pay pared to a fire really breaking out because the alarm fails to alert you. Now, you might still ask 。t. Ideally ,you match the four states correctly .However sometimes your brain decides that the consequences of missing a call are more serious than a false alarm .Therefore ,you bee more sensitive to vibrations so that you don39。it is either vibrating or Not ,Meanwhile ,you also have two possible states of mind 。t? This phenomenon ,which scientists call phanton ( 幻覺的 )phone vibration ,is very mon． Around 80% of people sruveyed say they have imagined their phones vibrating when they were actually still. So， what leads to this universal behavior ?According to the BBC ,the explanation lies in your brain39。s very difficult to make big changes in the way people travel .However ,an increase in the use of public transportation has begun. 25． Why did some car panies buy and destroy public transportation systems?

Mile Markers on the Road of Life B The way people in the US travel to and from work has changed a lot in the last fifty years. Before the Second World War, most people lived in the town or the city where they worked. Almost everyone either walked to work or used a good inexpensive transportation system Many of these systems were electrified and ran on tracks, so they used very little energy. After 1945, the US government built many new roads and highways. People moved farther and farther form the cities where they worked because they could drive their cars on these new roads from their suburban homes to work in the city. Some of the big car makers also bought the electrified transportation systems and destroyed them. As people stopped using public transporation , cities spent less money fixing old buses and trains or buying new ones. Public transportation got worse and worse. In the late 1960s, people found out that the increase in the use of cars led to many problems. There were always too many cars for the highway system, and terrible traffic problems developed. People were spending hours in traffic jams getting to and from work every day. In addition, the air in many cities became dirty because of pollution from millions of cars, and many people died in traffic accidents. As people began to get worried about how the use of cars was hurting the environment, cities began to spend more money on public transportation again, so fewer people would have to drive cars. When gas became very expensive in the mid1970s, the number of people taking public transportation began to increase .It39。ve e, but not how far we39。ve seen as many birthdays as I39。ll get cards and calls and maybe a few videos.
