period 4 reading and writing
the general idea of this periodthis period teaching and studying will center on reading and writing.as usual, the teacher can begin the teaching with revision the former knowledge, that is to say, the content of first impressions.this part can be also regarded as the lead-in, because the passage to be learned is the continued part of first impression.it will describe amazing things that li qiang has seen in the future ad 3005.as to reading training, the purpose of doing it is to help the students to form the good habit of reading with some strategy.the teacher should develop the students’ ability of scanning and skimming, including the implied meaning beyond lines.so at the beginning, get the students to prepare knowledge for reading.in order to reach that purpose, the teacher firstly will ask some questions about what they have learned in the second period, and then let them talk about what they can see in the picture.then let the students scan the passage and find what amazing things are mentioned.later, the teacher will ask the students to skim it and find out the main idea for each paragraph.the purpose of doing these is to help the students to form the good habit of reading.when reading a passage, we had better first read it as whole, that is, understand the structure of the passage and catch the main idea with the help of structure and title.the following step is to read the passage for the details.the teacher can design some teaching activities to help the students to know about more and more information by taking part in the reading activities.as a result, the teacher should be careful, cautious and creative when designing the reading activities.the reading activities had better be various, which can cause more students’ attention.at the end of reading, some activities should be designed to lead the students to understand the implied meaning beyond the passage.at the same time, let the students consider the writing purpose, which serves the purpose of the author writing it.besides reading, the class is also expected to learn and practise writing skill.by studying the passage, the students should learn the ability of describing the things and what they imagine imitating the passage.the teacher should give the students some advice on how to succeed in describing the things and what they imagine.teaching important pointsmaster the skill of gist reading.develop the students’ ability of understanding the implied meaning.
three dimensional teaching aimsknowledge aimsget the students to know about what li qiang found in the future in ad 3005.learn the knowledge about how to write a passage about description of the things.ability aimsmaster the skill of gist reading.develop the students’ ability of understanding the implied meaning.improve the students’ writing ability.emotional aimsreading the passage is to attempt to cultivate students’ spirit of exploring science and future.
teaching procedurestep 1 greetingt: hello, my friends.ss: hello, miss wang.step 2 revisiont: do you still remember what we learned in the second period?s: first impressions.t: how did li qiang travel to the earth in ad 3005?s: with the help of his friend, he traveled by time capsule to the earth but one thousand years in the future.t: how did he feel when he found him in a completely strange world?s: he was confused by the new surroundings.t: good.now let’s make some sentences with“li qiang”to describe what he saw and experienced.s: li qiang suffered from the lack of fresh air on his arrival at the new world in the future.s: li qiang felt much better after putting on a special mask, though the air seemed thin there.s: li qiang got separated from his friend when they reached what looked like a large market.ss: ...step 3 pre-readingt: you did a good job.most of you reviewed what we learned.now let us guess what li qiang would go on visiting.s: he was to visit other planets by time capsule.s: i guess he would go to visit some interesting places.s: i think he would pay a visit to a family and a school.ss: ...t: if you were the author of the passage, what would you like to introduce to readers?s: i might introduce the aliens who he met in the future.s: i think i would describe the way of future life.s: if i were the author, i would prefer to write something about future school.t: some students seem to have the same opinion as the author, while some might be able to write a new passage for us to enjoy.i am glad to know you all have used your heads to have various answers.now study the picture on page 21 to tell me what you can see in the picture.s: i can see a strange thing is working in a special place.s: the strange thing has six hands and one leg, but its head is similar to ours.

research and activitiesget the students to participate in a competition about designing the future.the theme of the competition is robots in the future home.the students are asked to work in groups of four to design the robots in their minds.they will draw the pictures of the robots and also describe the size, appearance, personality and how to work.in order to attract more attention, the designers should give a vivid description about its outstanding advantages and function.in addition to beautiful appearance and extraordinary function, the designing should also be full of imagination. the group whose description is wonderful, together with imaginative, beautiful and functional design, will be the winner.

space program in the future

galaxyany of the systems of stars and interstellar matter makes up the cosmos.many such assemblages are so enormous that they contain hundreds of billions of stars.nature has provided an immensely varied array of galaxies, ranging from faint, diffuse dwarf objects to brilliant, spiral-shaped giants.virtually all galaxies appear to have been formed soon after the universe began, and they pervade space, even into the depths of the farthest reaches penetrated by powerful modern telescopes.galaxies usually exist in clusters, some of which in turn are grouped into larger clusters measuring hundreds of millions of light-years across.(a light-year is the distance traversed by light in one year, traveling at a velocity of 300 000 kilometers per second, or 650 000 000 miles per hour.) these so-called super clusters are separated by nearly empty voids, causing the gross structure of the universe to look somewhat like a network of sheets and chains of galaxies.

a future vehiclewhile many technological advances occur in an evolutionary manner, occasionally a revolutionary technological appears on the horizon that creates startling new conditions and profound changes.such is the case with the privately developed moller skycar, which is named after its inventor.the lamv is a vertical take-off and landing aircraft that can fly in a quick, quiet, and agile manner.it is a new type of vehicle that combines the speed of an airplane and the vertical take-off capability of a helicopter with some characteristics of a ground vehicle, but without the limitations of any of those existing modes of transportation.the lamv is not operated like traditional fixed—or rotary-wing aircraft.it has only two hand-operator uses to direct the redundant computer control twists to select the desired operating altitude and moves fore and aft to select the rate of climb.the right-hand control twists to select the vehicle’s direction and moves side-to-side to provide transverse (crosswise) movement during the hover and early-transition-to-flight phases of operation; it also moves fore and aft to control speed and braking.simply put, the lamv is user friendly.the lamv of the future will be 18 feet long, 10 feet wide, and 6 feet high and weight 2200 pounds.it will hold four passengers and a payload of 875 pounds (including fuel).the vehicle will have a maximum rate of climb of 6400 feet per minute and an operational ceiling of 30 000 feet.it will attain a top speed of 390 miles per hour at an altitude of 6000 feet and a cruising speed of 350 miles per hour at 25 000 feet, and it will have a maximum range of 900 miles at 80 passenger miles per gallon.the lamv also will be quiet enough to function as an acoustic“stealth”plane at 500 feet.it will have a vertical take-off and landing capability and emergency airframe parachutes, and it will be capable of using various fuels.
