1、Unit 2 Exploration,Teaching Objectives and Requirements,The students will learn how to read science fictions, specially the ones which appear to be ordinary short stories. The students will learn also the scientific events that function as the milestones in the development of human civilization. The

2、 students will also learn the importance of human space exploration.,Pre-reading task,Warm-up questions 1. Why do people have great interest in exploration? 2. What is the significance of space exploration?,While-reading task,Step 1 Word pretest,C C B A B C B C B C A,Step 2 Background information,Wi

3、th the Mars Express Beagle 2 lander set to touch down on the red planet in a little over a weeks time, Stuart Atkinson writes a letter to the lander that has the potential to change our understanding of Mars and our place in the universe.,Beagle 2 was an unsuccessful British landing spacecraft that

4、formed part of the European Space Agencys 2003 Mars Express(火星快车） mission. It is not known for certain whether the lander reached the Martian surface; all contact with it was lost upon its separation from the Mars Express six days before its scheduled entry into the atmosphere. It may have missed Ma

5、rs altogether, skipped off the atmosphere and entered an orbit around the Sun, or burned up during its descent. If it reached the surface, it may have hit too hard or else failed to contact Earth due to a fault.,The Beagle 2 is named after the HMS Beagle which twice carried Charles Darwin during exp

6、editions which would later lead to the theory of evolution.,Beagle 2 was due to land on Mars on 25th December 2003. The spacecraft was successfully ejected from Mars Express on 19th December 2003. Nothing has been heard from Beagle 2 and the mission is presumed lost.,Galileo,Galileo Galilei (15 Febr

7、uary 1564 8 January 1642), was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations and support for Copernicanism/kpnknizm /. Galileo has

8、been called the father of modern observational astronomy, the father of modern physics, the father of science, and the Father of Modern Science.,His contributions to observational astronomy include the telescopic confirmation of the phases of Venus金星, the discovery of the four largest satellites of

9、Jupiter木星 (named the Galilean moons in his honour), and the observation and analysis of sunspots. Galileo also worked in applied science and technology, inventing an improved military compass and other instruments.,Einstein,Albert Einstein was a German-born theoretical physicist who developed the th

10、eory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics and one of the most prolific intellects in human history. He received the 1921 Nobel Prize in Physics “for his services to theoretical physics, and especial

11、ly for his discovery of the law of the photoelectric effect光电效应”. The latter was pivotal in establishing quantum theory量子论 within physics.,Einstein published more than 300 scientific papers along with over 150 non-scientific works. His great intelligence and originality have made the word Einstein s

12、ynonymous with genius.,Neil Armstrong,Neil Alden Armstrong (born August5,1930) is an American former astronaut, test pilot, aerospace engineer, university professor, United States Naval Aviator, and the first person to set foot upon the Moon. His first spaceflight was the NASA Gemini 8 mission in 19

13、66, for which he was the command pilot机长, becoming one of the first U.S. civilians to fly in space.,Armstrongs second and last spaceflight was as mission commander of the Apollo 11 moon landing mission on July20,1969. On this mission, Armstrong and Buzz Aldrin descended to the lunar surface and spen

14、t 2 hours exploring while Michael Collins remained in orbit in the Command Module. Armstrong was awarded the Presidential Medal of Freedom by Richard Nixon along with Collins and Aldrin, the Congressional Space Medal of Honor by President Jimmy Carter in 1978, and the Congressional Gold Medal in 200

15、9.,Step 3 Students will be given 3 minutes to skim and scan the text and answer the following questions:,What or who is Beagle? What are the reasons for the writer writing to Beagle? Why does the author mention the important events in the history of human civilization? How many are mentioned?,What i

16、s Beagles specific mission to Mars? What might be the prospective outcome of Beagles mission to Mars? What impact will the outcome of Beagles mission have on human beings? Why does the author mention in the text the origin of the name of the Martian capsule-Beagle?,Key Points and Difficult Points in

17、 Teaching,fly free: separating itself from Mars Express and fly independently as a space capsule at stake: in danger your creators: human beings Im sure its creators sensed somehow, somewhere deep inside, that nothing would ever be the same again: here the author means that when human beings learned

18、 to use fire, they know very clearly that the course of the development of human civilization was sure to be changed.,crude: roughly made and in a very raw state instead of being sophisticated the cataracts of ignorance were suddenly removed: here the author means that thanks to the contribution of

19、Galileo, human beings began to know the fact that the earth is not the center of universe. In this sentence, a metaphor is used. deceptively-short equation: an equation which appears to be short but the substance it contains is complicated,awesome: arousing a mixed feeling of fear and respect one da

20、y our millennia-long exile on Earth was finally over: this sentence actually means that we human beings have been confined on the planet Earth for a thousand years or for a thousand years we have not been able to explore the space. And Neil Armstrongs landing on the moon marked the beginning of huma
