Introduction 2. Broad Questions • what are the names of the different planets of the solar system? • Do Martians really exist? Are they the being that have dug the canals on Mars? • If you were to take a trip through space, where would you prefer to touch down? 3. Outline A and B talk about imaginary trips through space: ----------- the moon ------------Venus ------------Jupiter ------------Saturn ------------Uranus, Neptune, Pluto ------------Mars ------------Mercury 4. Language Points 1) my long-cherished dream: a dream that has been long kept in my mind Compound adj., more examples: long-standing 长期存在的, long-lived 长寿的； 长久的,长期的； well-advised 稳妥的,谨慎的 well-balanced （指人）情绪稳定的， 神志清醒的, well-built （指人）身强力壮的，结实的, well-done （食物）熟透的, well-informed 有见识的，消息灵通的, well-fed 吃的好的，营养充足的 2) Although I could not leave my “name” there, I would certainly leave my footprints on the moon. ---- Although I could not be famous for my visit to the moon for could not be the first person landing on the moon, I would certainly leave my foot-print there at least. 3)But I will definitely spare Uranus, Neptune and Pluto in my schedule. ------But I will certainly not include visits to Uranus, Neptune and Pluto in my schedule. Here “spare” means “give up as not strictly needed”. 4)Supposing you had a lot of money, where would you like to go to for a holiday? “Supposing” or “supposing that” can introduce an adverbial clause of condition, which means “if we assume the fact or the possibility that”. Besides, “provided” or “providing” can also introduce the adverbial clause of condition, which mean “on the condition or under the surroundings that”. DIALOGUE II FUTURE PLANS AND INTENTIONS, PART 1(1课时) Work in pairs and take it in turns to ask and give answers about future plans or intentions: what to do after class what to do at weekend where to go during the Spring Festival when to go to Suzhou with your classmates READING I HOW FAR IS THE SUN FROM THE EARTH? (1课时) Introduction Sample questions • How far is the sun from the earth? • How did people get the accurate answer? • How fast does the airliner travel an hour? • Do you think you can reach the sun by plane? Why not? • Is the electric train faster that the airliner? • How long would it take the aircraft carrier to get to the sun? • Why is George Washington mentioned in the reading text? Why are New York and Philadelphia mentioned? READING II WHY EARLY BIRD (1课时) Introduction Sample Questions • What do microwaves transmit? • How do microwaves travel? • What would happen if we tried to send television signals directly from Europe to America? • What is the use of a TV relay station? • What can we do if we want to send TV signals across the Atlantic? • How does a communications satellite function? • Can you describe Early Bird briefly? • Can you name some other kinds of man-made satellite in use? GUIDED WRITING (1课时) A note of congratulations In writing a note of congratulation, one usually relates how he/she hears of the good news, what the good news is, how he/she is happy for the addressee…, and then extends his/her congratulations. Some reference versions for congratulations: Wish you a Merry Christmas and Happy new Year! Heartfelt congratulations on your graduation from the Oxford University! Please accept my heartfelt congratulations on… Let me offer my warmest congratulations on the happy occasion. BACKGROUND INFORMATION The Solar System The solar system consists of the Sun, the nine planets, sixty-three (63) satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth's orbit). The ecliptic is inclined only 7 degrees from the plane of the Sun's equator. Mercury Mercury is the closest planet to the Sun and is less than half the size of Earth. It has no moons, no atmosphere, and since it is so close to the Sun it is an extremely hot planet. The typical midday temperature on Mercury is over 750 degrees. Mercury is only visible briefly after sunset or before sunrise depending on the time of year. Mercury can be seen to go through phases similar to Venus but even with the largest telescope available, no surface detail can be revealed. Venus----The Morning and The Evening Star Venus is the brightest object in the sky after the Sun and our Moon. Due to the fact that its orbit is inside the Earth's, we can see Venus only when we are looking in the general direction of the Sun. It is visible only during the first few hours after sunset, when we call it the "evening star" or before sunrise when we refer to it as "the morning star." Venus is covered with thick layers of clouds that we are unable to see through. In 1982 a Soviet Lander took photos of the surface of Venus and revealed flat rocks and soil. Mars----The Red Planet Mars, also known as the red planet is a very interesting planet, mainly because of its rapid motion through the sky and because of it's reddish color. Mars has polar caps that are believed to contain water ice. Our recent visit to the red planet revealed a great amount of information that leads us to believe that Mars once had some life forms on the surface. Mars has 2 "moons" named Phobos and Deimos, which are actually only small orbiting chunks of rock. Jupiter----The Jovian Giant Jupiter is the largest planet in the solar system. It is 11 times the diameter of the Earth. It is also 3 times brighter than the brightest star visible to us, which is Sirius. With a small telescope, you can see light and dark colored bands across the planet. With a good scope you may also see a large reddish region on the planet known as the Great Red Spot (GRS), which is about 18,000 miles in size. It is a giant storm within Jupiter's cloud system. Jupiter also has four bright moons sometimes referred to as satellites. If you observe Jupiter and its moons nightly you will see that they change positions. Saturn----The Ringed Planet A Jovian planet, Saturn is 9.4 times the diameter of the Earth, almost the size of Jupiter. Saturn has an extensive ring system that extends outwards from the planet about 81,000 miles from its center. With a small telescope Saturn's rings are visible. The rings are made up of divisions called the Cassini Divisions. These rings are made up of tiny ringlets that consist of chunks of rocks ranging in size from small pebbles to huge boulders. Saturn has a total of 18 known moons. Uranus Uranus is a giant planet, about 4 times the diameter of Earth. Through a telescope it looks like a tiny greenish or bluish disk. This is because it has methane in its atmosphere that absorbs other colors. It has 5 large moons. All of the moons appear to be made up of rock and ice. Uranus also has a set of nine thin rings around it as observed by Voyager Neptune Neptune is another giant planet. Like Uranus, it gets its color from traces of methane in its atmosphere which is made up mainly of hydrogen and helium, giving the planet the blue color. The most obvious feature on Neptune is the Great Dark Spot (GDS) which is a circulating storm about the size of Earth. Neptune has 8 moons. Pluto The smallest planet and also the farthest away from us, remains basically a mystery. No detail of its surface is visible from Earth but the Hubble telescope revealed dark and light regions. It has one moon named Charon. Pluto is less than one-fifth the size of Earth, even smaller than our Moon. And now it is classified as a "dwarf planet“, excluded from the “nine planets”.
