They discovered that the pandas followed the protein. _48_ At the start of the cycle, they ate Bashania
6、fargesii leaves until they got the chance to feast on young shoots, which contained more protein. The more the shoots grew, the more their protein was diluted(冲淡)by fiber. That caused the pandas to move to higher ground, where Fargesia qinlingensis grew. First, they ate the shoots, but these, too, w

The North Star Among the pile of stars in the universe, there are a couple that are of great importance to people on Earth. The sun, of course,
17、is one of them. The other is known as Polaris, the North Star. _67_. Therefore, it is a great compass(指南针).When people in the northern part of Earth look toward Polaris, they can be certain that they are facing north. The permanence of Polaris in the north sky has helped countless people find their
18、destinations. Before the invention of modern navigation tools, sailors relied on Polaris. From the top of their ships, sailors would look for Polaris to figure out their place at sea. They figured out the angle between the star and the horizon to determine their latitude(纬度). As long as the equation
19、s were not wrong, the results were very reliable. Polaris also let sailors determine North, South, East, and West. _68_ To those who sail at night, changeable storms and dark clouds were more than annoying things._69_.Its possible for a captain to make an accidental wrong turn. The ship could become
20、 stranded at sea, and the frustrated captain would have no way to get the ship back on the right course. The sailors fears wouldnt be relieved until the clouds cleared and Polaris came back into view. Even today, sailors sometimes choose to steer by using Polaris on clear nights. _70_. The Big Dippe

27、 届高三英语二模考试试题 Section C Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need. A. If we see a line moving faster, we might switch without having enough extra informa
28、tion. B. About one in five people grew impatient at the back of the queue and switched to the other line in the hope of speeding things up. C. Do you hold your nerve and stay put, switch to another line in the hope it moves faster, or give up altogether? D. Based on his study, Buell says people shou
29、ld think hard about switching queues when they are the last in a line. E. In an unpublished working paper on the research, Buell notes that people tend to feel unhappiest at the back of a queue for the first 10 seconds or so. F. Although the number of people behind you has nothing to do with how lon
30、g you are going to wait, it shapes your behavior. No one enjoys the moment. You are stuck at the back of a queue and as those in other lines move ahead and get served, the time to decide arrives. _67_ This question has now been solved by researchers at Harvard Business School. According to what they
31、 have found in a new study, they suggest people think twice before switching queues. The research was led by Ryan Buell, an expert in service management. He looked into consumer queuing behavior after working with economists on what is known as “last-place aversion,” the discomfort people feel when
32、they know they earn less than others or consider themselves at the bottom of the social pile for some other reason. As a result of this aversion to being the last, when a person finds himself at the end of a queue, he can make decisions that he will later regret. Buell began by observing people at a
33、 multi-checkout grocery store and then set up an online survey. People who took part in the survey were told it would take about five minutes. In reality, it took only one minute, but when participants logged in for the survey, they were forced to wait in a virtual queue displayed on the screen. The
34、y started at the back and could wait, switch to a second queue or choose to leave. _68_ On average, however, those who switched waited 10 percent longer than if they had stayed put. Those who switched twice ended up waiting 67 percent longer than if they had never moved. “When we join a queue, we te
35、nd to make the most rational choice we can, which means joining the shortest queue. _69_ Unfortunately, we can often get it wrong,” said Buell. _70_ After that, the aversion fades. The researcher suggests people have a chat with the person in front so that they can pass the time more comfortably unt
36、il someone else joins behind them. “Remember that the person in front of you was the last until you arrived, so someone will show up if you hang around long enough,” Buell said. 上海市金山区 2017 届高三英语二模考试试题 Section C Directions: Complete the following passage by using the sentences given below.

For centuries, scientists and natural philosophers have proposed that stars in the night sky have planetary systems similar to
38、our own solar system. The existence of extrasolar planets, or exoplanets, has long been discussed. _67_ Although not the first exoplanet discovery, a planet near a sun-like star was discovered by astronomers in 1995. This kicked off an era of exoplanet hunting, with thousands of discoveries and conf
39、irmations following in its wake. _68_ However, in 2015 NASAs Kepler space telescope found its first Earth-sized planet in a “habitable”zone. This is the distance form a star where surface temperatures of a planet wouldnt be too hot or too cold for liquid water. So far, only a small slice of our gala
40、xy, the Milky Way, has been explored. Even so, scientists have confirmed over 3,500 exoplanets, with more being added every day. To detect exoplanets, scientists use data from a variety of sources. Large ground-based telescopes, earth-circling and sun-circling satellites all collect different types
41、of information. Because exoplanets are so far away and very close to stars, it is very difficult to see them directly. _69_ For example, when an exoplanet moves between its star and us, it causes a small drop in the stars brightness. Measuring this drop is the transit（凌日）method of discovery. NASAS K
42、epler space telescope has discovered many exoplanets this way. As a planet circles a star, it pulls on it and causes it to shake. _70_ Measuring these slight changes is the radial velocity（径向速度）method of discovering planets. It is one of the most productive methods for finding and confirming exoplan
43、ets. These are just two examples of the many methods scientists use in their hunt for exoplanets, hoping for more information and enhanced detail.

44、refully. Then answer the questions or complete the statements in the fewest possible words. Being a small business brings advantages the big ones can only dream of. Michael Heppell, author of the latest edition of “5 Star Service”, a book on customer service, has interesting take on this development
45、. “Im often amazed that smaller businesses think that the secret of success is to be more like the big ones, when in fact the opposite is true,” he said. He pointed to the very different stories of two fishmongers (鱼贩) in his home town. Having served customers including Heppell for many years, the t
46、wo were joined by a Tesco Extra, Waitrose and Marks & Spencer. The first fishmonger began to complain about these newly-arrived chains to the local press, and even his customers. He pointed out that he couldnt compete with them on price and finally closed down. “Fishmonger two was different,” explai
47、ned Heppell. “She worked hard to create a local brand and local loyalty. She would love to tell you about the fish, when and where it was caught and offer some little extras if you spent a few pounds more. She must have felt the effects of the three new arrivals in town but she didnt complain once.
48、She survived, and of course, since her competitor closed shes never been busier.” Small businesses that want to grow should stop trying to imitate the big names, advised Heppell. “Find out what they dont do that you can, and what you do that they cant. The secret is by providing brilliant levels of
49、service,” he went on to say. They should also start thinking about s peed, believes Heppell, and realize that this can differentiate them from larger competitors. “Smaller businesses can often change faster, adapt more easily and manage trends more quickly than the big boys. However, looking at many smaller businesses the opposite appears to be true. What can you do to get a first mover advantage?” Too often smaller business leaders feel that they have to offer whatever the larger players ar
