What are they?(Note：According to the present day scientific study, there are only eight planets, with the Plutoexcluded.)S: The Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.T: Which planet do we live on? Can you describe what it looks like?S: Earth. It supports a variety of life and 70% of the earth is covered with seas or oceans.Step 3 discussionWhere do we come from? Or we can say: Who are our ancestors?Do you know any ancient idea about the beginning of the universe?Pangu separates the sky from the earth.The sky and the earth were at first one blurred entity like an egg. Pangu was born into it. The separation of the sky and the earth took 18,000 years- the yang which was light and pure rose to become the sky, and the yin which was heavy and murky sank to form the earth. Between them was Pangu, who went through nine changes every day, his wisdom, greater than that of the sky and his ability greater than that of the earth. Every day the sky rose ten feet higher, the earth became ten feet thicker, and Pangu grew ten feet taller. Another 18,000 years passed, and there was an extremely high sky, an extremely thick earth, and an extremely tall Pangu. Then came the Three Emperors (the Emperor of the Sky, the Emperor of the Earth, the Emperor of the Men.)So these numbers came into existence and evolve like this. The number begins with one, becomes established at three, is completed at five, prospers at seven, and ends in nine. So the sky is ninety thousand li from the earth.Other legends about the beginning of universeThe Biblical Account"In the beginning God created the heavens and the earth. Now the earth was formless and empty, darkness was over the surface of the deep, and the spirit of God was hovering over the waters. And God said...."Day 1 : God spoke and separated light from darkness creating Day and NightDay 2 : God spoke and separated the water creating sky and oceanDay 3 : God spoke and created dry landDay 4 : God spoke and created the sun, moon, and starsDay 5 : God spoke and created living creatures in the air and seaDay 6 : God spoke and created the land animals and manDay 7 : God rested and blessed this day calling it HolyIndiaBrahma has created the world many times. This creation is repeated every four ages or yugas. There are four yugas in one eon or kalpa. In the beginning of each kalpa the world is a watery chaos.As Brahma thought beings were created. The demons were created by a wind from his rectum. After creating the demons he discarded his body which became night. He assumed a new body and out of his mouth came the shining gods or devas. This body was also discarded and became day. With his next body he created ancestor spirits. With his fourth body Brahma created human beings were created. This discarded body became the moon. With the fifth body Brahma had a strange thought and he created ogres, terrible creatures, that wanted to devour the primordial sea of chaos. In shock at what he had done he then created ghouls, or Gandharvas. Finally he regained his senses and created birds, mammals, plants, and all the other life that we see today.Step 4 appreciationPlay a video for the studentsHow many types of life on the earth have you seen in the video? Name them.Students tell everything they have seen in the video. (Present on the blackboard the new words and a general picture of the topic of this lesson.)Big Bang universe a cloud of dust globe violent atmosphere water plants cells shellfish fish land animals insects amphibians reptiles dinosaurs mammals apes(monkeys) humansStep 5 fast readingHow did life develop through history?Read fast and find out the answers.A cloud of dust →a solid ball →presenceQ: Why was it necessary for plants to grow before animals?(Plants provided oxygen for animals to breathe.)Step 6 RetellingSuppose you are Dr. … who studies astronomy. You are invited to g ive a speech to the school students about the development of life on “Earth Day” (April 22nd).Homework:1.Search the Internet for the information of the development of life.2.Read and learn good words, phrases or structures from Reading.Period 2 reading (2)Step 1 Scanning1 What’s the style of the text?2 What’s the main idea of the text?Step 2 skimmingFind out the main idea of each para.Step 3 careful readingFinish off the chart.Key to the exercise:2.shellfish and all sorts of fish 5.amphibian(on land and in water)7.reptiles(on land) 8.dinosaurs(on land) 9.mammals(on land)T: That’s all for this passage. Now let’s deal with some language points.Step 4 consolidationT or F1.The earth was a cloud of dust before it combined into a ball around the sun.2.The water vapour, carbon dioxide, oxygen, nitrogen formed the earth’s atmosp here.3.The coming of small plants growing in the water made the earth different.nd animals appeared before the green plants on land.5.Dinosaurs produced their young by laying eggs.6.The earth may become too hot if too much carbon dioxide was put into the atmosphere.Step 5 RetellingRetell the text using about 100 words.Notes: Use the two questions and the chart to retell the passage;The possible version below can be used as a material for both retelling and dictation. Retelling:The explosion of the earth produced water vapor, which turned into water when the earth cooled down. Water allowed the earth to dissolve harmful gases into the oceans and seas. That made it possible for life to begin to develop. The arrival of small plants encouraged the development of early shellfish and all sorts of fish. Many millions of years later the first green plants began to appear on land. Later land animals appeared. Some were insects. Others, called amphibians, were able to live on land as well as in the sea. When the plants grew into forests, reptiles appeared for the first time. Later, dinosaurs developed. They became the most important animals on the earthfor millions of years. After they disappeared, mammals became more important. They were the last group of animals and they were different because they produced their young from within their bodies. Small clever animals, with hands and feet, appeared and spread all over the earth. As time went by, they covered the earth and have become the most important animals on the planet.Step 6 discussion1.What should we do with the global warming problem?Suppose: some of you are officials of the government/some of you are ordinary people2.Suppose you were an expert of astronomy, and now you and your workmates are preparing for a meeting whose topic is the beginning & and the prospect(展望) of the life/ human being on the earth. Work in your group, and try to develop your speech!HomeworkRetell the passage according to the form..Remember important language points.English weekly page 4 part 2。

2020版高考英语一轮基础习选题 Unit 4 Astronomy the science of the stars(含解析)

Unit 4 Astronomy the science of the stars李仕才一、阅读理解。

The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language. We use the Internet to connect with family and friends and stay in touch with issues we care about.The list goes on and on.As far as the Internet being a part of our lives—well, that train has left the station. That expression means there is no going back. If you prefer boating, you can say that ship has sailed.So, there may be no going back to an Internet-free life. But can using the Internet too much be bad for our health?It might be, say researchers.Study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure.High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke.High blood pressure can also cause heart and kidney disease. It is also closely linked to some forms of dementia, a brain disease. Dementia is marked by memory disorders, personality changes, and a reduced ability to reason.Let’s introduce something about the study of it.The Henry Ford Hospital in Detroit, Michigan did the study. It involved 335 young people, from 14 to 17 years old. One hundred thirty-four of the teens were described as “heavy Internet users”. Researchers found that out of these 134 teens, 26 had high blood pressure.The researchers say the study is the first to connect heavy web use and high blood pressure. Other research has connected that heavy Internet use with health problems including anxiety, depression and obesity.The lead researcher of the study is Andrea Cassidy-Bushrow. In a statement she said, “Using the Internet is part of our daily life but it shouldn’t consume us. ”For the purpose of the study, she explains, teens considered heavy Internet users were online on “average 25 hours a week. ”Ms Cassidy-Bushrow adds that it is important for teens to take “regular breaks from their computers or smartphones” and to do some “kind of physical activity. ”She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.【文章大意】互联网如此有用并且融入我们的生活, 但过度使用它, 会导致多种健康问题。
