Passage2When people want to find out about the weather, they usually go to their radios, TVs, newspapers, or the Internet. However, you can also find many weather signs among wildlife because of their highly developed senses. Drops in air pressure affect small mammals (哺乳动物) and insects in many ways. Try looking in or near the house. Mice are good weather indicators. People who spend a lot of time outdoors have observed that field mice come out of their holes and run around before a storm.Deer leave the high ground and come down from the mountains before a storm. If you see this, you can be sure that there will be a storm within two days. When you see large numbers of sea crabs on a sandy beach, it is time to leave. A change in air pressure over the water warns the crabs that a storm is coming. To escape the stormy sea pounding the shore, they leave the water and seek shelter on land.Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become easily annoyed and will fight over a piece of bread. Other birds sing just before a storm. It seems they know they won’t get another chance for an hour or two. Birds also seek shelter before a storm. You will sometimes see birds resting in trees or staying closely together on a wire near a building. This is a good storm signal.Seabirds sit out a storm on land. Anytime you see seagulls sitting on the ground in large groups, reluctant to fly, it is not a very good day to go sailing. It is unusual to see large groups of birds flying overhead in the summertime. Watch for other weather signs if you see this. You should also stay alert if you see migrating birds flying in the wrong direction. These birds may be flying ahead of a storm. And if you can’t see a bird anywhere, look out! They may have flown to a different place because a violent storm is coming in their direction.Questions 41-45 are based on this passage.41. What’s the main idea of the passage?

Passage 1We all laugh. We all hurt. We all make mistakes. We all dream, that’s life. It’s a journey. Please follow these rules to make the journey of your life a journey of joy! Staying positive through the cold season could be your best defense against getting ill, new study findings suggest.In an experiment that exposed healthy volunteers to a cold or flu virus, researchers found that people with a generally sunny disposition (性格) were less likely to fall ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a “positive emotional style” can help ward off the common cold and other illnesses.Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less troubled by a scratchy throat or runny nose. “People with a positive emotional style may have different immune response to the virus,” explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. “And when they do get a cold, they may interpret their illness as being less severe.Cohen and his colleagues had found in a previous study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional trait itself had the effect.For the new study, the researchers had 193 healthy adults with complete standard measures of personality traits, self-perceived health and emotional “style”. Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy, tense and hostile had a negative style. The researchers gave them nose drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains, or sneezing (打喷嚏) they had, while the researchers collected objective data. Cohen and his colleagues found that based on objective measures of nasal woes (鼻部的不适), happy people were less likely to develop a cold.Questions 36-40 are based on this passage.36. The new study findings in the experiment suggest that _________.
