阅读下面短文并回答问题,然后将答案写到答题卡相应的位置上(请注意问题后的词数要求)。

  [1]Oops! In your rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat, if you pick them up within 5 seconds of dropping them. But you might want to think again. Scientists now say that 5 seconds are all it takes for foods to become contaminated with enough bacteria to make you sick.

  [2]Bacteria 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. One of these food-borne bacteria is Salmonella. 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 factory. 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 carefully.

  [3]Being a good housekeeper is another good way to prevent infection. If household surfaces aren’t washed thoroughly, they can support Salmonella for weeks. A team of scientists at Clemson University in South Carolina have tested the 5-second rule, using sandwich ingredients. First, they placed a known amount of Salmonella cells on three surfaces: wood, tile, and carpet. They then placed a slice of bread and a slice of bologna(博洛尼亚大红肠) 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.

  [4]So forget the 5-second rule. If your toast lands on the floor, throw it away. Stick a fresh slice of bread in the toaster. And this time, be careful not to drop it!

I was in a rush as always, but this time it was for an important date I just couldn’ t be late for! I found myself at a checkout counter behind an elderly woman seemingly in no hurry as she paid for her groceries. A PhD student with not a lot of money, I had hurried into the store to pick up some flowers. I was in a huge rush, thinking of my upcoming evening. I did not want to be late for this date.

  We were in Boston, a place not always known for small conversation between strangers. The woman stopped unloading her basket and looked up at me. She smiled. It was a nice smile —warm and reassuring — and I returned her gift by smiling back.

  “Must be a special lady, whoever it is that will be getting those beautiful flowers,” she said.

  “Yes, she’ s special,” I said, and then to my embarrassment, the words kept coming out. “It’ s only our second date,but somehow I am just having the feeling she’s ‘the one’ ,”Jokingly, I added, “The only problem is that I can’ t figure out why she’ d want to date a guy like me.”

  “Well, I think she’s very lucky to have a boyfriend who brings her such lovely flowers and who is obviously in love with her,” the woman said. “My husband used to bring me flowers every week — even when times were tough and we didn’ t have much money. Those were incredible days; he was very romantic and — of course — I miss him since he’ s passed away.”

  I paid for my flowers as she was gathering up her groceries. There was no doubt in my mind as I walked up to her. I touched her on the shoulder and said, “You were right, you know. These flowers are indeed for a very special lady.” I handed her the flowers and thanked her for such a nice conversation.

  It took her a moment to realize that I was giving her the flowers I had just purchased.“You have a wonderful evening, I said. I left her with a big smile and my heart warmed as I saw her smelling the beautiful flowers.

  I remember being slightly late for my date that night and telling my girlfriend the above story. A couple of years later,when I finally worked up the courage to ask her to marry me,she told me that this story had helped to seal it for her — that was the night that I won her heart.

Running like the wind, roaring (咆哮) like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China.

  This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund.

  The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950's, there were over 4000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species.

  Sixty­six of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves.

  “Breeding has damaged the quality of the species”, said Pei Enle, deputy director of the Shanghai Zoo.

  To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts(本能) and can hunt wild animals by themselves at the African base.

  “South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in”, said Lu Jun, office director of the National Wildlife Research and Development Center.“We tried in Fujian Province, but it was not successful as there was not a complete eco­chain(生物链) and there was a lack of space.”

  The tigers should return to China in 2007 when the reservations in Fujian are ready.

1.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?

A. Because it has lost its natural instincts.

B. Because there is not a complete eco­chain.

C. Because there is no space for it.

D. Because uncontrolled hunting has destroyed its natural living conditions.

2.How is the programme of sending several tigers to South Africa getting on?

A. Its effect still remains to be seen.

B. Two tigers can already compete with their wild cousins.

C. Some of the tigers are already on the road to recovering their natural skills.

D. The tigers should be able to recover their instincts completely by 2007.

3.By saying “but they are nothing like their wild cousins”,the writer means that________.

A. they are no longer feared by other wild animals

B. they don't know how to hunt or kill

C. a complete change has resulted in the species because of breeding

D. to reintroduce them into the wild has become an urgent task

4.What is the purpose of sending young tigers to South Africa?

A. To help the tigers recover their ability to live in the wild.

B. To provide them with a better environment.

C. To get the tigers to go on a tour.

D. To find a complete eco­chain for them.

5.Which one is NOT the reason for South Africa being chosen as the training place?

A. Because the tigers can hunt wild animals by themselves at the African base.

B. Because South Africans are skilled at dealing with the tigers.

C. Because there is a complete eco­chain and enough space there.

D. Because the country has good natural conditions for the tigers to learn in.

What could be cuter than your puppy giving his doggy friend a kiss on the nose? Nothing, really. But is your dog actual-fly planting a kiss on his friend? Yes, but that’s only one of the reasons your dog may lick another dog’s nose. Here are some other reasons why your dog may lick another dog’s nose.   

  During an introduction, a shy and lower-ranking dog will lower his head, avoid direct eye contact and gently extend his tongue to lick the nose of a more confident and high-ranking dog. The first dog licks the nose of the second dog to simply make it know that:he comes in peace.

  Dogs who are already friends will also trade kisses. Two strongly bonded dog pals will lick and clean each other. They give each other “dog kisses” showing friendship.

  Puppies also “kiss” their mothers, but it's not a gesture of love. When puppies stop suckling(吸吮)their mothers’ tits for milk and start to eat semisolid(半固体)food instead;they lick their mothers’ mouths and noses in the hope of getting the mother to regurgitate(反哺) some semi-digested food.

  So how to help your bashful dog make friends with other dogs? You can carefully select confident-but-friendly and good-tempered dogs to play with your shy dog, to help him develop his social skills. Also consider taking him to a special training class that focuses on socialization and positive training technique.

  Do not disturb them when your two dogs play “kiss” briefly with each other. Sit back and enjoy this display of friendship. Then call them over and have them do a command such as “sit’’ or “shake paws”. Offer them treats as a reward for being good to each other.

  If you foster(收养)a dog and have three or more resident dogs, introduce the foster dog to your brood dog one at a time and let muzzle licking between them happen naturally. Start with your least reactive or most friendly dog. Never force an in production between the dogs because this can deepen the foster dog’s submissiveness or spark a fight.

1.We know a shy and lower—ranking dog licks the nose of a higher-ranking dog to         .

A. ask the dog for helpB. show he is friendly

C. show his anger D. show his respect for him

2.What can we know about two dogs who are already friends?

A. They seldom give each other kisses.        

B. They usually avoid direct eye contact.

C. They like keeping their friendship a secret.    

D. They show their friendship by “dog kisses”.

3.What does the underlined word “bashful” in Paragraphs 5 mean?

A. Shy.     B. Honest.     C. Lovely.       D. Little.

4.What should you do if your two dogs play “kiss” briefly with each other?

A. Ask them to stay away from each other immediately.  

B. Ask them to shake tails.

C. Ask them to have a fight.

D. Give them a reward for being friends.

5.The writer wrote this passage to_________.

A. tell us about a study he did recently
