Small talk serves as a gateway toward deeper conversation. Some introverts don’t realize that small talk will actually help them get to the bigger topics. You don't need to stay on small talk forever. However, sometimes introverts feel that even the short amount of time it takes to get into the real conversation is a waste of time. Small talk is very fast. Someone says something and this should be followed up with a quick response. But introverts like to chew on their words before saying them aloud. Before they answer, they’ll mull over different thoughts.
Small talk by its very nature invites more people to join in. The more people who join the conversation, the more the introvert will tend to step back. As a result, they’ll be quiet. Small talk is about throwing out subjects in the hope that one or more of them can be turned into a common point of interest.
The listening involved with small talk is not in-depth. The purpose is about listening \so you can figure out the right topics to spend some time on. Introverts tend to be great listeners, but they use active listening rather than light listening. This makes them wonderful friends, but can also make it difficult for new people to understand why they’re so quiet.
24. How do introverts respond to a chat?
A. They try to avoid it. B. They get excited about it. C. They give it their full attention. D. They focus on unimportant topics. 25. What do we know about small talk?
A. It goes slowly. B. It costs people a lot of time. C. It contributes to deeper topics. D. It makes no sense.
26. What does the underlined phrase \ A. Give up. B. Think over.
C. Write down. D. Forget about.
27. How can we become a good talker in small conversations? A. Figure out the deep meaning of questions. B. Think twice before answering questions. C. Try to find shared topics. D. Be a quiet listener.

An online supermarket company—Ocado in the UK, has recently displayed a robotic hand
that can pick fruits and vegetables!
When an embryo is in the womb (子宫), the very first sense it develops is touch. The sense of touch is also the one that lasts the longest—as we get older and our vision and hearing begins to weaken, touch still remains. Humans use their touch to protect themselves, to create emotional relationships with other people and to experience pleasure. Can you imagine life without it?
The sense of touch comes from a network of nerve endings (神经末梢) and special touch receptors on the surface of the skin. While there are different kinds of touch receptors, they help us judge pressure, texture(质地) and vibrations (震动). They are located in our fingertips, palms, soles of our feet, face, lips and tongue.
When we touch something, the receptors feel the touch and through a network of nerves send signals to the brain. This informs the brain about the location of the touch, the amount of force used, and the speed at which it was used.
Several different techniques have been tried in the past few years to create such a robotic hand—using three fingers. But this latest design by Soma copies the human hand. The gripper (钳子) is made up of flexible materials which grasp the thing based on its size and shape. Then air pressure is used to control the movement of the robotic fingers to pick objects safely and without causing damage.
The next step would be for the robot to judge how ripe the fruits and vegetables are, and apply pressure accordingly. Members of the research team are currently working on adding computerized vision to the robots, so that they can see what they are grasping.
Does all this mean robots can replace people? According to Ocado, it helps improve productivity by removing some of the repetitive tasks done by humans.
28. What is focused on in the second paragraph? A. The origin of touch. C. The development of touch.
B. The importance of touch. D. The process of transporting touch.
29. What does the underlined word \ A. The brain. B. The touch.
C. The nerve. D. The signal.
30. What is the typical feature of the latest robots? A. They can see what they're taking hold of.
B. They can take the place of people in work places. C. They can tell whether the fruits and vegetables are ripe. D. They can hold things firmly according to their outer features. 31. What can be a suitable title for the text? A. A Sense of Touch for Robots B. A Robotic Hand for Classifying Fruits C. A Robotic Hand with a Gentle Touch D. A Robot Made of Flexible Materials

Bees are unbelievably territorial (有地盘意识的), fighting to death to defend their home with painful stings (蛰刺). But killer bees are particularly fierce. They appeared after African bees were imported to Brazil in the 1950s. By the 1980s, they had spread north to the United States, outgunning native bees along the w ay. Their massive attacks have killed more than 1,000 people.
Mario Palma, a biochemist at Sao Paulo State University in Rio Claro, Brazil, who studies social behavior in bees, w anted to understand the basis of this aggression. So he and his colleagues swung a black leather ball in front of some killer bees and collected the bees w hose stingers got stuck in the ball during the attack. They also collected killer bees that remained in the cell. The analysis suggested that killer bee brains have two proteins(蛋白质) that—in the aggressive bees—quickly break into pieces to form a so-called “neuropeptide (神经肽)”, they reported this week in the Journal of Proteome Research.
Palma and his colleagues already knew that bee brains have these two proteins. “We were taken aback w hen we identified some very simple neuropeptides, which were produced in a few seconds,” Palma said. Killer bees that remained in the cell did not make these neuropeptides, he reported. And when his team put these neuropeptides into young, less aggressive bees, they “became aggressive like older individuals”.
Palma added that these neuropeptides also increase the production of energy and alarm chemicals. They could also encourage the nerve cells in killer bees needed to make the stinging attack. “There is a fine biochemical regulation in the killer bee brain,” he said. Researchers have found these neuropeptides in other insects, but few had associated them with “fight” behavior.
32. What is special about bees? A. They are particularly fierce. B. They show territorial behavior. C. They were imported to Brazil. D. They live in harmony with other insects.
33. Why did Palma and his colleagues perform the experiment? A. To understand bees social behavior. B. To study why killer bees are aggressive. C. To prove bees love flying around.
D. To learn how bees communicate with each other.
34. What finding surprised the researchers during the experiment? A. There are two proteins in killer bee brains. B. Young killer bees are fiercer than older ones. C. The killer bees make an attack immediately. D. Killer bee brains produce neuropeptide quickly.
35. What will the author probably talk about in the following paragraph? A. The form of these neuropeptides in killer bees. B. The function of these neuropeptides in other insects. C. The application of these scientific methods in other insects. D. The production of energy and alarm chemicals in killer bees. 第二节 (共5小题；每小题2分，满分10分)
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。选项中有两项为多余选项。
Cold weather during winter months may keep many people from leaving home and running in the open air. However, a new study shows that the drop in temperature is a good reason to run. 36
Many people say running in winter can be difficult. Two reasons are the low temperatures and bitter winds. 37 That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body's dehydration (脱水) levels are lower
