She recommends yearly scalp check- ups should be as regular as annual medical examinations. “ At HairMantra, you will receive expert advice with solutions for your whole lifestyle, products and supplements for your hair problems, and a hair care routine to use at home.

My husband recommended we give her a computer to play against. I wasn't sure my mother was ready for it. After all, it had taken 15 years to persuade her to buy an electric cooker. Even so, we packed up our old computer and delivered it to my parents' home. And so began my mother's adventure in the world of computers. It also marked the beginning of an unusual teaching task for me. I'd taught people of all ages, but I never thought I would be teaching my mother how to do anything. She had been the one teaching me all my life: tō cook and sew, to enjoy the good times and put up with the bad. Now it was my turn to give something back. It wasn't easy at the beginning. There was so much to explain and to introduce. Slowly but surely, my mother caught on, making notes in a little notebook. After a few months of Scrabble and other games,I decided it was time to introduce her to word processing(文字处理). This proved to be a bigger challenge to her, so I gave her some homework. I asked her to write me a letter, using different letter types, colors and spaces. “ Are you this demanding with your kindergarten pupils?” she asked. “ No, of course not,”I said.“ They afready know how to use a computer.” My mother isn't the only one experiencing a fast personal growth period. Thanks to the computer, my father has finally got over his phone allergy. For as long as I can remember, any time I called, my mother 1/4 would answer. Dad and I have had more phone conversations in the last two months than we' ve had in the past 20 years. 24. Why did the author decide to give her mother a computer? A.

Tasks are scheduled so tightly that break times are often used to finish the day's work. This type of schedule is far too demanding for long missions on the International Space Station (ISS). ISS crewmember s usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by emaıf, Tnternet phone and through private video conferences. While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crewmember put together a collection of family photos, messages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. And as from early 2010, the Internet became available on the ISS, giving astronauts the chance to do some“ web surfing” in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space. Many astronauts say that one of the most relaxing things to do in space is to look out the window and stare at the universe and the Earth's vast land mass and oceans. 28. What does the word“mumic” in Paragraph 1 probably mean? A. Copy. B. Remember. C. Improve. D. Waste. 29. Which of the following best describes the families of the astronauts on the ISS? A. Proud and patient. B. Worried and annoyed. C. Excited and Curious. D. Caring and thoughtful. 30. What can we know about the astronauts on the ISS from the last paragraph? A. They regard space life as common. B. They love to see the Earth from space. C. They feel life in space boring and tiring. D. They live happier in space than on the Earth. 31. The passage is mainly about how the astronauts . A. connect with people on the Earth B. work for longer missions in space C. spend their free time in space D. observe the Earth from space D Black Friday refers to the day after Thanksgiving. On this particular day, crowds of shoppers flood into stores all over the country to take advantage of the season's biggest holiday bargains. But the real story behind Black Friday is a bit complicated. The most commonly repeated story behind the post- Thanksgiving shopping- related Black Friday tradition links it to retailers (零售商). As the story goes, after an entire year of operating at a loss, 214 recorded in red ink, stores would supposedly earn a profit, marked in black ink, on the day afterThanksgivıng, because holiday shoppers spent so much money on discounted products Though it's true that retail.companies used to record losses in red and profits in black when doing their accounting, this version of Black Friday's origin is not an accurate story behınd the tradition. The true story behind Black Friday, however, is not as sunny as retailers might have you believe. Back in the 1950s, police in the city of Philadelphia used the term to describe the chaos (混乱) that happened on the day after Thanksgiving, when tens of thousands of suburban shoppers and tourists flooded into the city in advance of the big Army- Navy football game held on that Saturday every year. Not only would the police not be able to take the day off, but also they would have to work extra- long shifts dealing with the additional crowds and traffic. The term didn't spread to the rest of the country until much later, however, and as recently as 1985 it wasn't in common use nationwide. Sometime in the late 1980s. however, retailers found a way to reinvent Black Friday and turn it into something that reflected positively on them and their customers. The result was the“ red to black” concept mentioned earlier. The Black Friday story stuck, and pretty soon the term's darker roots in Philadelphia were largely forgotten. 32. What is usually believed to be the origin of Black Friday? A. The great profit retailers may gaın. B. The way retailers do their accounting. C. The much money shoppers spend. D. The biggest bargains on this day. 33. Why did police in Philadelphia refer to the day after Thanksgiving as Black Friday? A. They had to compete with more shoppers for bargains. B. They had to give up the big Army- Navy football game. C. They had to work more hours to deal with the chaos. D. They had to advance to suburb to fight against floods. 34. The retailers reirvent Black Friday in the late 1980s . A. to attract more customers to shop B. to create the“ red to black” concept C. to spread the term across the country D. to change people's impression of it 35. Which could be the best title of the passage? A. The Real History of B lack Friday B. The Biggest Shopping Holiday C. A Term with Various Meanings D . A Forgotten Truth of Red and Black 第二节 七选五 How to Succeed in Science To succeed in science, you need a lot more than luck. In my view, you have to combine intelligence with a willingness not to follow conventions(常规惯例) when they block your path forward. Thus, these have come to be my rules for success. 1. 36 That might sound proud, but the fact is that you must always turn to people who are brighter than yourself. It's like playing any game. Even as a child, I never wanted to play games with anyone who was as bad as I. If you win, it gives you no pleasure. And in the game of science or life, the highest goal isn't simply to win; it's to win at something really difficult. 37 2. Take risks To make a huge success, a scientist has to be prepared to get into deep trouble. If you are going to make a huge jump in science, you will very likely be unqualified to succeed by definition. 38. . This can be more tnampersonally upsetting. 3. Never dco anything that bores you. My experience in science is that someone is always telling you to do things, and then leave you alone. I'm not good enough to do well in something I dislike. 39 It's very hard to succeed if you don't want to be with other scientists --- you have to go to key meetings where you spot key facts that would have escaped you. And you have to chat with your competitors, even if you find them unacceptable. So my final rule is: 40 A. Avoid foolish people. 3/4 p Watch out for brighter minds. C In fact, I find it hard to do well in even something I like. D If you can't stand to be with your real peers, get out of science. E. Be sure you always have someone to save you from a deep mess. E . Besides, you even have to be prepared to dısbelıeve your scientific heroes. G. Put another way, it's to go somewhere beyond your ability and come out on top. 第三节 完形填空 The day had started out as usual for Mrs. Ito until the late afternoon when the news of destructive tsunami(海啸) came over the radio.
