Unit1 Tales of the unexplained-Welcome to the Unit教案

                are there any monsters in these areas?                why do ships or planes disappear in this area? do you think it is too mysterious?               suppose there is a ship equipped with the latest scientific equipment and it can make contact with scientists on land at any time, do you think it will be possible to solve the mysteries?  l         sharing information1 pair students up first. let different pairs focus on different questions. if possible, the first question can be adapted easily like this:do you believe in ufos? what may be the explanations of ufos?—— aliens from space without a doubt
—— military test craft without a doubt
——some ufos are alien, some are test craft
—— ufos are evidence of human space travel
—— ufos are neither alien nor test craft
—— ufos don't existencourage students to express their agreements or disagreements about it.2 ask different pairs to summarize their answers and then report them back.sample answers1 like any other intelligent and rationale person, i have a firm belief in ufos. in fact, i have seen a few myself. ufo stands for unidentified flying object, that is, an object, apparently moving in the sky, that we cannot identify. however, if you ask me whether i believe spacecraft carrying visitors from outer space, i would say ‘no’. i do not believe it.2 the continent of antarctica was discovered in 1818. a map known as the 'piri reis' map, a genuine document made in constantinople in 1513, clearly shows the continent of antarctica. how could this have been possible if antarctica was not discovered until 300 years later? antarctica was supposed to have been covered by ice for the last million or so years, but samples taken from sediment deep beneath antarctica in 1949 revealed that great rivers had once flowed in antarctica until about 6000 years ago.3 i’m always interested in the stories of ufos and aliens. and i hope i will have the chance to meet one some day. if it really happens to me, i will ask questions such as ‘who or what are you?’ ‘where are you from?’ ‘how long does it take to travel from your place to our planet?’ i will try my best to communicate with them, discovering what their life is like and why they come to the earth.
