Is it because the spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked hot food，or is there some connection between spices and healthy food?Researchers from Cornell University think that it is because spice plants have some important chemicals(化学物质)．These chemicals can kill bacteria(细菌) which spoil food．"Most common spices can kill 75 to 100 percent of the bacteria in food，" explains one of the scientists．The bacteria grow more easily and spoil food more quickly at higher temperatures．For this reason，it is more difficult to keep food from spoiling in hot climates．Do you like your food spicy? Your answer probably tells something about the country you come from．If you like spicy food，it is possible that hundreds of years ago，when there were no fridges，people in your country started using spices to keep the food from spoiling．The traditional spicy dishes helped those people to live longer，healthier lives．Today，in a time of fridges，the spices just make the food taste good．1．The chemicals in spices keep food from spoiling by ________．A．making food taste better B．making food hotterC．killing bacteria in food D．preventing bacteria getting into food 2．Food goes bad more quickly in hot climates because ________．A．high temperature makes more bacteriaB．high temperature helps bacteria grow fasterC．bacteria get used to hot foodD．bacteria spoil food only at high temperature3．According to the passage，spices are useful in all the following things except _______．A．replacing fridgesB．helping you to live longerC．helping to keep you healthierD．making your food taste betterBThis is not a diet．It's a simple way to lose weight．And you don't even have to give up the food you love or join a gym．You just follow some habits that thin people have．Keep them，and you'll become thin．(1) Wake-upWhen you wake up in the morning，sit up slowly without using your hands．With legs straight out，bend(弯曲) forward until you feel sore in your back．It will burn about 10 calories(热量单位：卡路里)．(2) Start with soupWhen you have a meal，order a clear soup，and have it before having the main food．In this way，you'll feel fuller，so you'll eat less when the main food comes．(3) An apple (or more) a dayApples are full of fiber(纤维) and water，so your stomach will want less．The study shows that people who eat at least three apples a day lose weight．(4) Stand up and walk aroundEvery time you use the mobile phone，stand up and walk around．Heavy people sit on average(平均) two and a half hours more each day than thin people．This skill is very important as standing up and walking around will burn 50 or more calories．Use these skills，and you will have a big weight loss．( ) 1．What should we have first if we want to eat less main food?A．Ice cream B．Soup．C．Salad．D．Cheese．( ) 2．Why does eating apples make one's stomach want less food?A．Because apples are full of fiber and water．B．Because apples are sour．C．Because apples are delicious．D．Because only apples are filled with calories．( ) 3．Which of the following may the author disagree?A．Sitting up slowly without using your hands helps burn calories．B．Eating apples every day is good for people's health．C．You have to join a gym if you want to lose weight．D．It's good to walk around while talking on the mobile phone．( ) 4．What's the purpose of the passage?A．To give some advice on how to lose weight．B．To advice people to eat apples every day．C．To tell people how to enjoy a better life．D．To advice people to give up bad habits．( ) 5．In which part of a newspaper would you most probably read the passage?A．Shopping．B．Teaching．C．Family．D．Health．CA large number of people in the world eat fast food．Whenever you go into a fast food restaurant，you can see lots of people enjoying their meals there．But do you know in which country people like fast food best?The English people like the fast food best，while the French are the least interested in quick meals，according to survey done last year．The survey of thirteen countries shows 45% of the English people say they can't give up fast food because it's delicious．And 44% of Americans and 37% of Canadians say the same．The French，proud of their delicious and high-class cuisine，don't like fast food．81% of them think it is unhealthy，followed by 75% of the Japanese．How about the Chinese?
