Cassidy ran around to the far side of the site to cut the thief off while the others wandered the neighborhood hoping he had dumped the loot(赃物)in a backyard.No luck.So they decided to ask fesidents whether they'd seen the guy.When they knocked on the door of one row house,they were in for a surprise.Unknown to them, he had already emerged from the construction site-and was hiding behind a bush by that very house/As the owner opened the door,the suspect darted out fromn behind the (bush)...and right into the arms of campus police,who'd joined the chase shortly behind the runners.The members of this running group are not hard-core athletes.But they do understand the benefit of a little exercise."Running is typically a useless sport where you turn fat cells into heat,"Cassidy told The Philadelphia Inquirer.“But occasionally it can be useful,and here was one of those opportunities."24.Why do the group members gather together?A.To do some stretching.B.To have a regular run.C.To deliver a lecture.D.To cover some topics.25.What does the underlined word“sprinted”in Paragraph 2 probably mean?A.Dashed.B.Pushed.C.Jumped.D.Escaped.26.We can infer that the success of the(haso is mainly due toA.the assistance of the runnersB.the owner of the row houseC.the campus police on patrolD.the joint efforts of the people27.Which of the following best describes Cassidy?A.Athletic and generous.B. Courageous and ambitious.C.Helpful and humorous.D.Thoughtful and demanding.CFood experts say washing could spread the germs on your turkey in the kitchen sink or nearby food. But it's been a challenge trying to convince cooks to stop rinsing(冲洗)off raw poultry. Germs that can make people sick are common in the guts of healthy poultry and are legally allowed to be on raw turkey and chicken.The assumption is that nobody eats their poultry raw,and that thorough cooking will kill the bacteria.The do-not-wash raw poultry advice from the USDA is relatively new and perhaps hasn't caught on because it goes against the common belief that washing makes things clean,said Chapman.Benjamin Chapman,a study author and food safety expert at North Carolina State University,said the instinct to wash raw poultry/goes back at least decades when people relied more on visual/clues to spot problems with poultry.Meanwhile,washing hands and surfaces are also important.But food preparation is a complicatedact,and germs from poultry can be spread even if it's not washed,especially when birds are removed from packaging.The USDA-funded study stresses that point.(Researchers sprayed raw chicken with a harmless strain of E.col(大肠杆菌)and watched volunteer cooks at test kitchehs. Among those who washed their raw chicken,about a quarter ended up spreading the bacteria to their lettuce.But even some of those who did not rinse the chicken got germs on the lettuce.And there are other opportunities for germs to survive on turkeys: melting and cooking.To ensure a bird is thoroughly cooked,they say to use a thermometer to check that the deepest and thickest parts of it have reached 165 degrees.Even after the meal is cooked,you aren't out of the danger zone.,To keep turkeys and -other leftovers safe, experts say they should be refrigerated after two hours.28,People don't accept USDA's advice because_A.the advice is relatively newB.cleaning seems more trustworthyC.cooks clean the turkey before cooking itD.heat can kill most germs and no one eats raw food29.What can be concluded from Paragraph 4?A.Food packages carry germs.B. Hands and surfaces are easy to get E.coli.C.Germs from a turkey can be spread whether it is washed or not.D.Multiple methods should be applied to food to get rid of germs.30.Which way may help to cook a turkey safely?A.Rinse off the turkey before it is heated.B.Keep the turkey away from the lettuce and refrigerator.C.Wash hands and packages before taking out the turkey.e a thermometer to check the temperature of the turkey.31.From which section of a magazine is the text probably taken?A.Culture.B.Science.cation.D.Medicine,DMicroplastics are everywhere in our environment.It's hardly surprising that the tiny fragments have also been found in humans.A new study shows that Americans are consuming as many as 121,000 particles each year.Measuring 50 to 500 microns in length,microplastics come from a variety of sources,including large plastics that break down into smaller and smaller pieces. Therefore,much /remains unknown about the common existence of these materials within the human body,as well as their impact on human health.Hoping to fill in some of these gaps,a research team led by Kieran Cox,a PhD candidate at the University of Victoria,looked at 26 papers assessing the amount of microplastics in commonly consumed food items,among which are seafood,sugars, salts,honey,alcohol and water.The team also evaluated the potential consumption of microplastics through inhalation(吸入)'using previously reported data on microplastic concentrations in the air and theenvironmental,Protection Agency's reported respiration rates. Based on these data,the researchers calculated that our annual consumption of microplastics via food and drink ranges from 39,000 to 52,000 particles. When microplastics taken in through inhalation are taken into account,the range jumps to between 74,000 and 121,000 particles per year.The authors of the study found that people who drink exclusively from plastic water bottles absorb an additional 90,000 microplastics each year,compared to 4,000 among those whe only consume tap water."This shows that small decisions,over the course of a year,really matter and have an impact."Cox says.The new study,according to its authors,was the first to investigate "the accumulative human exposure”to microplastics.But in all likelihood,,the research tells only a small part of the entire story. Collectively,the food and drink (that the researchers analyzed represent,15 percent of Americans' caloric intake. The team could not(account for food groups like fruits,vegetables and grains because there simply is not enough data on their microplastic content.For those worried about microplastic consumption,cutting down bottled water is a good place to start.But to the heart of the problem,we have to stop producing and using so much plastic.32.What makes it difficult to know microplastics commonly exist in the human body?A.The quality.B.The quantity.C.The shape.D.The size.33.How did Kieran Cox's team calculate the potential consumption of microplastics?A.By studying papers.B.By comparing the impacts.C.By analyzing the data.D.By conducting experiments.34.Which of the following is true according to the text?A.Drinking less plastic bottled water helps to take in fewer microplastics.B.The study is among the earliest to investigate human exposure to microplastics.C.Cox's team gained comprehensive information of microplastics taken in by humans.D.People consume 74,000 to 121,000 particles of microplastics per year from food and drink35.What is the best title for the text?A.The Potential Problems of MicroplasticsB. Microplastics Coming From Various SourcesC. Microplastics Found Within Human BodiesD.The Impact of Microplastics on Human Health第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
