ASince I started working part-time at a grocery store, I have learned that a customer is more than someone who buys things. To me, a customer is a person whose memory fails entirely once he or she starts to push a shopping cart(车). One of the first things customers forget is how to count. There is no other way to explain how so many people get in their express line, which is clearly marked 15 items(件) or less, with 20, 25 or even a cart load of items.Customers also forget why they came to the store in the first place. Just as I finish ringing up an order, a customer will say, “ Oops, I forgot to pick up a fresh loaf of bread. I hope you don’t mind waiting, while I go to get it.”Five minutes later, he’s back with the bread, a bottle of milk, and three rolls of paper towels. What is stranger is that customers also seem to forget that they have to pay for their groceries. Instead of writing a check or looking for a credit card while I am ringing up the groceries, a customer will wait until I announce the total. Then, in surprise, she says , “ Oh no, what did I do with my check book?” After 5 minutes of digging through her purse, she borrows my pen because she has forgotten hers. But I have to tolerate customers because they pay my salary, and that’s something I can’t afford to forget.21. What does the author say about his customers?A .They can not count numbers.B. They sometimes jump the queue.C. They don’t know how to express themselves.D. They behave as if their memories had totally failed.22. According to the text, who are supposed to be in the express line?A Customers with nothing purchased.B. Customers with not more than 15 items.C. Customers with items between 15 and 2523. When customers arrive at the check-out counter,they_______A. find their pens lostB. go back and get more itemsC. can not wait to pay for their groceries.D. prefer paying by check to paying with a credit card.24. We can infer from the text that ________A. business in the grocery store runs wellB. the author finds his present job full of funC. the author’s part-time job calls for patienceD. customers go to grocery stores without planning.BFlappy Bird is flapping(拍打) its wings no more. The popular game for mobile equipment was removed from online stores on Sunday by its Vietnamese creator. Who said its fame “destroys mysimple life”Dong Nguyen, who created the game in just two to three days, was making as much as $50,000 a day from the game’s advertising income. In several Twitter posters, he said the game’s removal was not due to legal issues(问题) and that he may make a follow-up.Mr. Nguyen, who describes himself as an “ enthusiastic independent game maker”, also said on the micro-blogging mobile game so far. Coming out in May 2013, the game was free to download and required players to tap the screen to keep the bird in flight.In spite of its simple graphs, Flappy Bird was an extremely difficult game since many users could only keep the bird in the air for a new seconds before it hits an obstacle (障碍物) and falls.After Mr. Nguyen took the game down, many fans turned to social media to ask for its return. The game is no longer a available through online stores, but it still works on phones that had previously downloads it. However, some fans expressed their relief that the game was gone. One user described Flappy Bird as “ an addictive game that everyone hates to love” while another said, “I think it’s for the best, and for the best of all the broken –down phones out there.25. Dong Nguyen took Flappy Bird down because________A. it was against the lawB. it was easily destroyedC. it disturbed his normal life.D it could break down phones.26.What can we learn about Dong Nguyen from the text?A. He is addicted to playing games.B. He likes to make games by himself.C. He earned a lot by selling Flappy Bird.D. He rose to fame after removing his game.27. What were the users' reactions to Dong Nguyen's removing the game?A. Some felt happy and relaxed.B. Some got so angry that they accused him.C. Some regretted they couldn't keep the bird in flight.D. Some asked social media to help develop another game.28. What would be the title for this text?A. Flappy Bird-A Mobile GameB. Flappy Bird-A Computer GameC. Dong Nguyen - A Game CreatorD.

According to the text ,if you're tired of hotels in the summer, you can ______.A choose a cottage room for a changeB build an apartment in Moon IslandC buy a furnished house in Costa RicaD share a studio close to the city centerDMusic lessons in early childhood bring about changes in the brain that could improve its perfor mance far into adulthood, researchers say.Brain scans of young adults showed those who had formal musical training before seven had thic ker brain areas dealing with hearing and self-awareness .The findings note how brain development can be influenced by the age when children start to lea rn a musical instrument , and how those changes can continue into later life."Early musical training benefits kids more than just making them enjoy music. It changes the bra in, which could bring about cognitive advances as well," said Yunxin Wang of Beijing Normal Un iversity.“Our results suggest it’s better to start musical train ing before seven, which agrees with what most piano teachers recommend,” she added. She hoped the results might help parents decide when was the best for their children to learn an instrument.The brain’s cortex(皮层) plays a leading role in one’s abiliti es, from thought and language to memory and attention. The area matures rapidly in the early years of life, and its development could be affected more if a person starts musical training before it fully matures.Wang studied 48 Chinese students aged between 19 and 21 who had received formal music training for at least a year sometime between the ages of 3 and 15. Each had a scan to measure the thickness of the brain’s cortex.After considering sex and the number of years spent having music lessons, Wang found that musical training that started before seven appeared to thicken areas of the brain involved in language skills and executive function, which is a person’s ability to plan and accomplish tasks.“We’re not sure why these changes occur, but a rea sonable explanation is that early starters might depend more on hearing clues(线索) when learning music, since it might be more difficult for younger children to read music,” Wang said.32. According to the researchers, musical training before the age of seven can _______________.A. contribute to future work.B. create a successful lifeC. develop all-round abilitiesD. deal with puzzling problem33. When conducting the research with the students, Wang __________.A. tested their language abilitiesB. watched their musical performancesC. focused on school behavior and achievementsD. measured the thickness of the brain’s cortex34. It can be inferred from the last paragraph that _____________.A. it must be hard for kids to read musicB. kids are more likely to learn music by hearingC. Wang’s explanation has been the most reasonableD. Wang will research into the reasons for the brain change35. For what purpose does the author write the text?A. To describe the development of brain.B. To challenge the previous discoveries.C. To present the findings of the research.D. To give advice on how to learn music.第二节(共5小题;每小题2分,满分10分)EBFGC根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
