year keep the Christmas spending within a certain amount but can still afford the gifts that your loved ones will enjoy Never has this concern been greater in recent years than right now Even so there are several things that you can do to help Hit the sales No one wants to get up at four o clock in the morning and fight to get the best deal on Black Friday and it s surely very tough to pick up the courage and get out there in the cold for a good deal but sometimes it can be well worth Many retailers 零售商 offer specials all through the day and some even offer online Black Friday specials so you may still be able to get a great deal on Black Friday Pay close attention to advertisements Once the Christmas shopping season is coming retailers hungry for business will do just about whatever to get you in the store Pay very close attention to weekly advertisements of sales among the major retailers and you may be lucky enough to find different prices for the same thing in different shops Shop online Some of us don t like running from store to store in order to get the best price on the perfect gift and some of us don t like to go out in the cold at all thankfully for us we can do online shopping The world of online shopping lets people visit all the major retailers as well as some specialty stores that could only be found on the Internet Customers can find exactly what they are looking for at the best possible price without ever having to leave the house With traditional Christmas shopping consumers are sometimes limited to what s left in stock if 2 they wait too long to get to a particular store 1 The first paragraph implies that A nowadays not many people can afford expensive gifts B recently many people don t want to spend money on gifts C Christmas is a time to make our loved ones enjoy their gifts D Christmas is a time to make us feel free to buy our loved ones gifts 2 In the writer s opinion it is rewarding on Black Friday A if the weather is not very cold B if we don t have to fight for the best deals C if we don t have to get up early D if we get what we want at a good price 3 We can have more choices A on Black Friday B in a particular store C on the

follow the 5 second rule which claims foods are safe to eat if you pick them up within 5 seconds from dropping them But you might want to think again Scientists now say that 5 seconds are all it takes for foods to become contaminated 被污染的 with enough bacteria to make you sick Bacteria are single celled organisms that can cause many kinds of illnesses Some kinds of bacteria can grow on food If we eat foods on which these bacteria are growing we can become sick Common symptoms include vomiting 嘔吐 and diarrhea 腹瀉 One of these food borne bacteria is Salmonella 沙門氏菌 It makes 1 4 million people sick every year Earlier this year 370 people became sick after eating peanut butter that had been contaminated with Salmonella at the manufacturing plant Salmonella are often found in raw eggs and chicken Cooking kills these bacteria which is why it is so important to cook eggs chicken and other foods thoroughly Being a good housekeeper is a second tip for preventing infection If household surfaces aren t washed thoroughly they can support Salmonella for 3 weeks But how long does it take these bacteria to attach to food To answer that question a team of scientists at Clemson University in South Carolina decided to test the 5 second rule using sandwich ingredients First they placed a known amount of Salmonella cells on three surfaces wood tile and carpet They placed a slice of bread and a slice of bologna on each surface for 5 30 or 60 seconds After just 5 seconds both the bread and bologna picked up enough bacteria to make you sick So forget the 5 second rule If your toast lands on the floor toss it out 4 What is a 5 second rule A If you drop food on the ground you can t eat it unless you pick it up within five seconds B If you drop food on the ground you can t eat it unless you pick it up five seconds later C If you drop food on the ground you can eat it even you pick it up five seconds later D If you drop food on the ground you can eat it at any time after you pick it

food D They only can be found on food 6 How can people avoid the infection of Salmonella A Never eat peanut butter B Never eat chicken and eggs C Never eat food unless they re cooked D Wash hands before dinner 7 Why did the scientists at Clemson University make the experiment A Because they wanted to see if Salmonella cells can grow on such kind of food B Because they wanted to see whether the 5 second rule is correct or not C Because they wanted to find out the best food among the three 4 D Because they wanted to see whether bacteria can make one sick or not 二 短文填空 根據(jù)短文內(nèi)容
