23、an once.Questions 26 to 35 are based on the following passage.The method for making beer has changed over time. Hops (啤酒花)，for example, which give many a modem beer its bitter flavor, are a (26)_ recent addition to the beverage. This was first mentioned in reference to brewing in the ninth century.
24、Now, researchers have found a (27)_ingredient in residue (残留物）from 5,000-year-old beer brewing equipment. While digging two pits at a site in the central plains of China, scientists discovered fragments from pots and vessels. The different shapes of the containers (28)_they were used to brew, filter
25、, and store beer. They may be ancient “beer-making tools,” and the earliest (29_evidence of beer brewing in China, the researchers reported in the Proceedings of the National Academy of Sciences. To (30)_that theory, the team examined the yellowish, dried (31)_inside the vessels. The majority of the
26、 grains, about 80%, were from cereal crops like barley (大麦),and about 10% were bits of roots, (32)_lily,which would have made the beer sweeter, the scientists say. Barley was an unexpected find: the crop was domesticated in Western Eurasia and didnt become a (33)_food in central China until about 2,
27、000 years ago, according to the researchers. Based on that timing, they indicate barley may have (34)_ in the region not as food, but as (35)_material for beer brewing.注意：此部分试题请在答题卡2上作答。A) ArrivedB) B) consumingC) C) directD) D) exclusivelyE) includingF) informG) rawH) reachedI) relativelyJ) remains

The Blessing and Curse of the People Who Never ForgetA handful of people can recall almost every day of their lives in enormous detailand after years of re
30、search, neuroscientists (神经科学专家) are finally beginning to understand how they do it.A For most of us, memory is a mess of blurred and faded pictures of our lives. As much as we would like to cling on to our past, even the saddest moments can be washed away with time.B Ask Nima Veiseh what he was doi
31、ng for any day in the past 15 years, however, and he will give you the details of the weather, what he was wearing, or even what side of the train he was sitting on his journey to work. “My memory is like a library of video tapes, walk-throughs of every day of my life from waking to sleeping,” he ex
32、plains.C Veiseh can even put a date on when those tapes started recording: 15 December 2000, when he met his first girlfriend at his best friends 16th birthday party. He had always had a good memory, but the thrill of young love seems to have shifted a gear in his mind: from now on, he would start r
33、ecording his whole life in detail. “I could tell you everything about every day after that.”D Needless to say, people like Veiseh are of great interest to neuroscientists hoping to understand the way the brain records our lives. A couple of recent papers have finally opened a window on these peoples
34、 extraordinary minds. And such research might even suggest ways for us all to relive our past with greater clarity.E “Highly superior autobiographical memory”（or HSAM for short) first came to light in the early 2000s, with a young woman named Jill Price. Emailing the neuroscientist and memory resear
35、cher Jim McGaugh one day, she claimed that she could recall every day of her life since the age of 12. Could he help explain her experiences?F McGaugh invited her to his lab, and began to test her: he would give her a date and ask her to tell him about the world events on that day. True to her word,
36、 she was correct almost every time.G It didnt take long for magazines and documentary film-makers to come to understand her “total recall”， and thank to the subsequent media interest, a few dozen other subjects (including Veiseh) have since come forward and contacted the team at the University of Ca
37、lifornia, Irvine.H Interestingly, their memories are highly self-centred: although they can remember “autobiographical” life events in extraordinary detail, they seem to be no better than average at recalling impersonal information, such as random (任意选取的）lists of words. Nor are they necessarily bett
38、er at remembering a round of drinks, say. And although their memories are vast, they are still likely to suffer from “false memories”.Clearly, there is no such thing as a “perfect” memorytheir extraordinary minds are still using the same flawed tools that the rest of us rely on. The question is, how
39、?I Lawrence Patihis at the University of Southern Mississippi recently studied around 20 people with HSAM and found that they scored particularly high on two measures: fantasy proneness (倾向)and absorption. Fantasy proneness could be considered a tendency to imagine and daydream, whereas absorption i
40、s the tendency to allow your mind to become fully absorbed in an activity to pay complete attention to the sensations (感受)and the experiences. “Im extremely sensitive to sounds, smells and visual detail,” explains Nicole Donohue, who has taken part in many of these studies. “I definitely feel things
41、 more strongly than the average person.”J The absorption helps them to establish strong foundations for recollection, says Patihis, and the fantasy proneness means that they revisit those memories again and again in the coming weeks and months. Each time this initial memory trace is “replayed”, it b
42、ecomes even stronger. In some ways, you probably go through that process after a big event like your wedding day,but the difference is that thanks to their other psychological tendencies, the HSAM subjects are doing it day in, day out, for the whole of their lives.K Not everyone with a tendency to f
43、antasise will develop HSAM, though, so Patihis suggests that something must have caused them to think so much about their past. “Maybe some experience in their childhood meant that they became obsessed (着迷）with calendars and what happened to them,”says Patihis.L The people with HSAM Ive interviewed
44、would certainly agree that it can be a mixed blessing. On the plus side, it allows you to relive the most transformative and enriching experiences. Veiseh, for instance, travelled a lot in his youth. In his spare time,he visited the local art galleries, and the paintings are now lodged deep in his a
45、utobiographical memories.M “Imagine being able to remember every painting, on every wall, in every gallery space, between nearly 40 countries，” he says. “Thats a big education in art by itself.” With this comprehensive knowledge of the history of art, he has since become a professional painter.N Don
46、ohue, now a history teacher, agrees that it helped during certain parts of her education. “I can definitely remember what I learned on certain days at school. I could imagine what the teacher was saying or what it looked like in the book.”O Not everyone with HSAM has experienced these benefits, howe
47、ver. Viewing the past in high definition can make it very difficult to get over pain and regret. “It can be very hard to forget embarrassing moments,” says Donohue. “You feel the same emotionsit is just as raw, just as fresh. You cant turn off that stream of memories, no matter how hard you try.” Veiseh agrees. “It is like having these open woundsthey are just a part of you,” he says.P This means they often have to make a special effort to lay the past to rest. Bill, for instance, often gets painful “
