d to diabetes and insomnia(失眠 ). The most upgraded gene is linked to heart disease. So changing sleep by tiny amounts can upgrade or downgrade genes that can influence our health and the diseases we suffer from when we sleep too little. The important message is that getting close to eight hours of sleep a night can make a dramatic difference to our health in just a few days through the way it looks after our genes. kind of relation is directly discussed in the passage? A. Sleeping hours and changes of genes. B. Sleeping hours and diseases. C. Changes of genes and diseases. and health. can we learn about Professor DerkJan Kijk’ s experiment? A. The experiment was carried out to find the answer to how genes affect sleep. B. The experiment took a period of more than two weeks to reach a conclusion. C. His volunteers were divided into two groups with two different sleeping patterns. D. Blood samples of the volunteers were checked afterwards to decide how many genes changed in sleeping. of the following may be concluded from the passage? A. The experiment was performed at the University of Surrey in early 2020. B. Bodyclock genes are associated with heart disease, cancer and Type 2 diabetes. C. Sleep restrictions may contribute to disease like diabetes, insomnia, and heart disease. D. － 8 hours’ sleep pattern makes little difference pared with － 7 hours’ sleep pattern. of the following can be inferred from the findings of the sleep research? A. When there is a sleep restriction, genes to do with cell repair and replacement function less. B. In a sleep, several hundred genes change in the amount. The more changes, the worse results. C. When genes are up regulated, they do good to health。 when genes are down regulated , they do harm to health. D. Eight hours of sleep a day can be beneficial to our health in that it looks after our genes. D The oceans are unique to our pla. No other pla in our solar system has liquid water. The oceans cover about 70% of the earth39。 s surface. They contain about 97% of the earth39。 s water supply. Life on earth originated in the seas. The oceans continue to be home to an incredible number of plants and animals. We know very little about the oceans. Because they are so deep and dark, they are hard to study. But scientists are discovering new strange creatures all the time. We are learning more by using satellites to look at the oceans39。 surfaces and by using buoys (航标 ) to measure temperature and saltiness. Special vehicles can now travel deep into the dark oceans to see what mysteries can be discovered. More of the sun39。 s heat is assimilated by water along the equator than at the poles. This means the water at the equator is warmer than water at the poles. These different water temperatures cause the water in the oceans to move. This is called an ocean current. The air above ocean currents also moves. The warm or cold ocean air moves over the land as wind. Oceans are also a really important part of the water cycle. Evaporation（蒸发） from oceans creates most of the world39。 s rainfall. Plants on land need the rain to absorb nutrients from the soil. The oceans are also home to all kinds of sea life. These include fish, whales, dolphins, octopi, lobsters, crabs and shrimps. There are also jellyfish and kinds of plants, such as plankton, kelp and sea grass are part of the forest of the seafloor. Carbon dioxide inoxygen out! Oceans help to capture and store carbon dioxide(C02). They are the largest natural carbon sinks in the world. Oceans trap about1/4of the CO2 that humans put into the air. Oceans also release oxygen. Half of the world39。 s oxygen is produced by these tiny plants! 32. What does the author think of oceans? A. They are amazing. B. They are mon. C. They are boundless. D. They are unimaginable. 33. To know more about the mysterious oceans,____. A. scientists use satellites in the oceans B. scientists are discovering new strange creatures C. scientists are using satellites to monitor the depth of oceans D. scientists are introducing scientific equipment in the research 34. What does the underlined word assimilated mean in the passage? A. Taken in B. Given off. C. Cut down. D. Held back. 35. It can be inferred from the passage that____ A. oceans produce much carbon dioxide B. it is not safe to live by the oceans C. oceans provide humans with rich resources D. humans can only depend on oceans for water 第二部分 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。 What attitude would you have to disappointments in life? 36 Find out how a chair， a pair of sunglasses and other items can hold unexpected promise for controlling your anger． 1． Take A Seat—Right Now There‟s a reason you‟ve probably never gotten into an angry state of mind from a chair． W． Robert Nay， a clinical professor， says， “Our brains bee conditioned to associate sitting and lying down with feeling relaxed． ‟‟ 37 Sitting down， Nay says， sends a message of safety and security to your brain． 2． Don‟t Get Mad， Get Organized。
