Gold medal performances require some serious nutrition. Have you ever wondered what these successful athletes eat to stay in peak shape?Keri Glassman, a registered dietitian and founder of Nutritious Life Meals, appeared on “Good Morning America” today to give you a glimpse into the diets of some top athletes. Some of their meals could surprise you.Crazy Calorie CountGlassman said Olympians eat a lot of food-quantities that for ordinary people would constitute pigging out.One secret of swimmer Michael Phelps’ astonishing performance in the 2008Olympics in Beijing was consuming as many as 12,000 calories in one day.Athletes can eat like this and not gain any weight because their workouts are intense. According to Glassman, Phelps’ workouts can burn 4,000 to 6,000 calories in a day, and those calories must be added in order to train the following day.Snacking SecretsSome athletes eat strange foods that improve their performance. Yohan Blake, the Jamaica sprinter and 100-meter world champion, has stolen champion sprinter Usain Bolt’s thunder on the track during the Olympic trials, Asked about how he gets his energy. Blake answered that he eats 16 bananas per day,Glassman said.Jonathan Horton, the lead gymnast on the US team, has a blood sugar problem. His solution is honey. When he starts to feel shaky at the gym, he takes honey to boost his energy, Classman said.Foods for RecoveryWhat are the best foods to help the body recover after harsh competition?For Olympic swimmer Ryan Lochte, the recovery meal is grilled chicken breasts with Alfredo sauce, whole-grain spaghetti and a salad with lemon juice and olive oil. Lochte, who recently cut out junk food, candy and soda, has undertaken a strength-training regimen(养生法)that involves flipping tractor tires, and tossing beer kegs, Glassman said.46.What’s the best title of this passage?A.Good Diet Makes a True Olympian.B.Olympians Have Olympic-size Appetites.C.Olympians’Strange Eating Habits.D. The Diet of Some Top Olympic Athletes.47.What does the underlined sentence probably mean?A.Ordinary people eat few pigs compared with Olympians.B.Olympians eat a lot more food than ordinary people.C.Olympians tend to eat a lot of high-quality food.D.Olympians eat a large amount of food, just like pigs.48.Which of the following is TRUE according to the passage?A.Ryan Lochte quit eating junk food, candy and soda for his better recovery.B.Yohan Blake finally beat Usain Bolt in the 100-meter track in the Olympics.C.Michael Phelps’astonishing performance was due to his eating lots of food.D.Jonathan Horton has a blood sugar problem because of taking too much honey.49.Which of the following is not the best food to help the body recover?A.Soda.B.Olive oil.C.Whole-grain spaghetti.D. A salad with lemon juice.50.The passage is most likely to be found in .A.a technical reportB.a fashion magazineC. an education columnD.a sports newspaperBCredit cards let people buy things now and pay for them over months or even years. But some people get deep into debt: Some banks have terms and charges that can make it harder for people to pay off that debt. In the United States, there are calls for stronger government supervision of the credit card industry. They offer economic power at a price. In 2004, Americans had about $800 billion in credit card debt. Now they own about $968 billion.Critics say banks made it too easy to get credit cards. But that may be changing. The crisis in the housing and credit they call markets is beginning to affect the credit card industry. More payments are late. Charges for late payments are a growing source of profit for banks. But late payments can also signal bad debts.The central bank, the Federal Reserve, says two-thirds of American banks have recently reported tighter lending requirements. Many people report having their credit limits reduced without warning.Some lawmakers are concerned that cardholders do not have enough protections from what abusive policies. These include actions like raising interest rates because of an unrelated event. Also, banks may raise the chances of a late payment by changing monthly payment dates for credit cards.According to a survey, 82% of Americans think credit cards provide a valuable service. But a majority, 58%, say they do not trust credit card companies. And three out of four think the government should regulate the industry more closely. Three out of four people feel there is always some condition that makes a card less appealing than the company made in scared. And a little more than half say they have had a card that was not as good as they expected. But close to 80% say no one really reads the terms and conditions when they sign up fora credit card.51. What does the underlined sentence in the first paragraph probably mean?A. We can enjoy more convenience using credit cardsB. Credit cards can improve your buying power.C. We can buy things at lower prices using credit cards.D. Credit cards bring more card debt as well as convenience.52. Which of the following is NOT mentioned in the text?A. Banks are making it harder for people to get credit cardsB. Some peo ple’s credit limits have been reduced.C. It is more difficult to borrow money from some banks.D. Banks are receiving more charges from late payments.53. Which of the following can be a case of abusive policies?A. Banks make credit cards look more attractive.B. Banks ignore the danger of bad debts.C. Banks raise interest rates with no good reason.D. Banks put off monthly payment dates.54. What can we know from the text?A.

The results of a survey about credit cards in Americans.CAnger at the practice of demanding dowries (嫁妆), which can lead to violence against brides, has prompted a takeoff of “Angry Birds” called “Angry Brides” that aims to highlight the illegal practice still prevalent in many South Asian countries.Dowries-such as jewelry, clothes, cars and money-are traditionally g iven by the bride’s family to the groom and his parents to ensure she is taken care of in her new home.The custom was outlawed more than five decades ago. But it is still widely practiced, with the groom’s family demanding even more money after marriage, leading to mental and physical annoyance that can drive the woman to suicide.“The Angry Brides game is our way of throwing a spotlight on the nuisance(陋习)of dowry.” said Ram Bhamidi, senior vice president and head of online marketing for , a matrimonial(婚姻的)website with two million members.“According to a 2007 study, there is a dowry-related death every four hours in India, We condemn this and have consistently run campaigns on social media to help create awareness of the issue”.The name of the app, available on the group’s home page, is a spinoff from the globally popular “Angry Birds” game, Its home page shows a red-clad, eight-armed woman resembling a powerful female Hindu goddess. Underneath, there is a caption: “A woman will give you strength, care and all the love you need … NOT dowry!”To play the game, users have to try and hit three dodging grooms--a pilot, a builder and a doctor. There are a variety of weapons to choose from, including a frying pan, broomstick, tomato and loafer.Each groom has a price tag, starting at 1.5 million rupees($29,165). Every time the player hits a groom, his value decreases and money is added to the player’s Anti-Dowry Fund,which is saved posted on their Facebook page.“Since we launched the game last week, m ore than 270,000 people have liked the app. Both men and women seem to be playing it”, said Bhamidi.56.What caused “Angry Brides” to appear online?A.Women’s rightsbeing seriously abused.B.Anger at the practice of demanding dowries.C.The bride’s gi ving a great many dowries.D.The popularity of Angry Birds online.57.Which of the following is TRUE about “Dowries”?A.The custom of giving dowries has been in practice for five decades.ck of abundant dowries may lead to the bride’s being in violenc e.C.The illegal practice of dowries is still popular in many African countries.D.More dowries the bride gives mean a high social status of her family.58.The underlined word “spinoff” probably means____.A.relationB.connectionC.copyD.fake59.Which of the following is NOT TRUE about the game “Angry Bride”?A.There are a variety of weapons to choose from.B.Ram Bhamidi thinks highly of the game.C.Men players don’t find the game enjoyable.D.The game character looks like a Hindu god dess.60.What is the text mainly about?A.Women’s unfair treatment in the marriage.B.The popularity of the game “Angry Brides”C.The groom’s demanding too many dowries.D.How to build an equal relation it the marriage.DGay marriage, and especially gay parenting, has been in the cross hairs in recent days.On Jan.6, Rick Santorum told a New Hampshire audience that children are better off with a father in prison than being raised in a home with lesbian parents and no father at all. And last Monday(Jan.9), Pope Benedict called gay marriage a threat “to the future of humanity itself”, citing the need for children to have heterosexual homes. But research on families headed by gays and lesbians doesn’t back up these above views. In fact, in some ways, gay parents may bring talents to the table that straight parents don’t.Gay parents “tend to be more motivated, more committed than heterosexual parents on average, because they chose to be parents.” Said Abbie Goldberg, a psychologist at Clark University who researc hes gay and lesbian parenting. Gays and lesbians rarely become parents by accident, compared with an almost 50 percent accidental pregnancy rate among heterosexuals, Goldberg said. “That translates to greater commitment on average and more involvement”.And while research indicates that kids of gay parents show few differences in achievement, mental health, social functioning and other measures, these kids may have the advantage of open-mindedness, tolerance and role models for equal relationships, according to some research. Not only that, but gays and lesbians are likelyto provide homes for difficult-to-place children in the foster system, studies show.Children of gay parents also show less care about gender difference. That’s likely because gays and lesbians tend to have more equal relationships than straight couples, Goldberg said.“Men and women felt like they were free to pursue a wide range of interests,” Goldberg said. “Nobody was telling them, ‘Oh, you can’t do that, that’s a boy thing,’ or That’s a girl thing.” 61.The underlined phrase “in the cross hairs”(in Paragraph 1) probably means .A.a great concernB.a big threatC.a political banD.a role model 62.It can be learned from the passage that Rick Santorum___. A.opposes the need for children to have heterosexual homes B.thinks children are better off with a father in prison C.believes children are better off in heterosexual homes D.is in favor of children being raised by lesbian parents 63.From Abbie Goldberg’s words, we can learn that____. A.Most heterosexual parents have children by accidentB.Gays and lesbians consider carefully before becoming parentsC.Heterosexual parents are not committed in the marriageD.There’s no gender difference in gay and lesbian parent ing 64.From the passage, we can infer that___. A.Children of gay parents are more talented B.Gay parents like adopting poor childrenC.Children of gay parents may enjoy more freedomD.Gay parents show no difference in social functioning65.Which of the following is the advantage of kids of gay parents?A.Tolerance .B.More talents.C.
