ery proud of her country. The next day Pi ngyu was l eavi ng London for Wi ndsor Castl e. “Perhaps I wi l see the Queen?” she wondered as she fel l asl eep. Uni t 3 FIRST IMPRESSIONS Spacem ail : li qi ang299A@GreatAdventureSpaceStati on. 15/11/3008(Earthti m e) Dear Mum and Dad, I stil l cannot beli eve that I am taki ng up thi s prize that I won l ast year. I have to remi nd m ysel f constantl y that I am real l y i n AD 3008 . Worri ed about the journey, I was unsettl ed for the fi rst few days. As a resul t, I suffered from “tim e l ag”. Thi s i s simi l ar to the “jet l ag” you get from fl yi ng, but i t seems you keep geti ng flashbacks from your previ ous ti m e peri od. So I was very nervous and uncertai n at fi rst. H owever, m y friend and gui de, Wang Pi ng, was very understandi ng and gave m e som e green tabl ets whi ch hel ped a l ot. Wel known for thei r experti se, hi s parents’ pany, cal ed “Future Tours”, transported m e safely i nto the future in a ti m e capsul e. I can sti l rem em ber the mom ent when the space stewardess cal ed us al to the capsul e and we cl im bed i n through a sm al opening. The seats were fortabl e and after a calm i ng dri nk, we felt sl eepy and cl osed our eyes. The capsule began swi nging gentl y si deways as we lay rel axed and dream i ng. A few mi nutes l ater, the journey was pl eted and we had ari ved. I was sti l on the earth but one thousand years i n the future. What woul d I fi nd? At fi rst m y new surroundings were di fficul t to tol erate. The ai r seem ed thi n, as though i ts bi nati on of gases had li ttl e oxygen l eft. Hi t by a l ack of fresh ai r, m y head ached. Just as I tri ed to m ake the necessary adjustment to thi s new si tuati on, Wang Ping apeared. “Put on thi s mask,” he advi sed. “It’l l m ake you feel m uch better. ” He handed i t to m e and i mm edi atel y hurri ed m e through to a sm al l room nearby for a rest. I fel t better i n no tim e. Soon I was back on m y fet agai n and flowi ng him to col ect a hovering carriage dri ven by puter. These carriages fl oat above the ground and by bending or pressing down i n your seat, you can m ove swi ftl y. Wang Pi ng fastened m y safety belt and showed me how to use i t. Soon I coul d fl y as fast as hi m. H owever, I l ost si ght of Wang Pi ng when we reached what l ooked li ke a l arge m arket because of too many carri ages fl yi ng by i n al di recti ons. H e was swept up i nto the centre of them . Just at that m om ent I had a “ti m e lag” fl ashback and saw the area agai n as i t had been i n the year AD 2020. I reali zed that I had been transported i nto the future of what was sti l m y hom etown! Then I caught sight of Wang Pi ng agai n and fl ew after him. Arri ving at a strangel ooki ng house, he showed m e i nto a large, bri ght cl ean room. It had a green wal , a brown fl oor and soft l i ghti ng. Suddenl y the wal m oved –i t was m ade of trees! I found l ater that thei r l eaves provided the room wi th m uchneeded oxygen. Then Wang Pi ng fl ashed a swi tch on a puter screen, and a tabl e and som e chai rs rose from under the fl oor as if by m agi c. “Why not si t down and eat a l ittle?” he sai d. “You m ay find thi s di ffi cul t as i t i s your first tim e travel trip. Just relax, since there i s nothi ng pl aned on the ti m etabl e today. Tom orrow you’l l be ready for som e vi si ts. ” H avi ng sai d thi s, he spread som e food on the table, and produced a bed from the fl or. After he l eft, I had a bri ef m eal and a hot bath. Exhausted, I sli d i nto bed and fel l fast asl eep. More news l ater from your l ovi ng son, Li Qi ng I H AVE SEEN AMAZING TH INGS My fi rst vi sit was to a space stati on consi dered the m ost m odern in space. Descri bed as an enorm ous round pl ate, i t spi ns sl owl y i n space to im i tate the pul of the earth’s gravi ty. Insi de was an exhi bi tion of the m ost uptodate i nventi ons of the 31st century. A gui de(G) showed us around al ong a m oveabl e path. G: Good m orni ng to al our vi si tors from 2020. Fi rst we’re goi ng to exami ne one of the latest form s of m uni cati on am ong our space ci ti zens. N o m ore typists working on a typewri ter or puter! N o m ore postage or postcodes! Messages can now be sent usi ng a “thoughtpad”. You pl ace the m etal band over your head, cl ear your mi nd, press the sendi ng buton, thi nk your m esage and the next i nstant i t’s sent. It’s stored on the “thoughtpad” of the recei ver. It’s qui ck, efi ci ent and envi ronm ental l y fri endl y. The onl y lim i tati on i s i f the user does not thi nk his or her message clearly, an uncl ear m essage m ay be sent. But we cannot bl am e the tool s for the faul ts of the user, can we? During the expl anati on I l ooked at the pair of sm al objects cal led “thoughjtpads” on a tabl e. They just l ooked li ke metal ri bbons. So ordi nary but so powerful ! Whi l e I was observi ng them, the path m oved us on. G: And now l adi es and gentl emen, we are i n the “environm ent area”. People used to col l ect waste i n dustbins. Then the rubbi sh was sent to be buri ed or burned, am I ri ght?(We nodded. ) Wel , now there’s a system where the waste is di sposed of usi ng the pri nci ples of ecol ogy. A gi ant m achi ne, al ways greedy for m ore, swal l ows al l the waste avai l abl e. The rubbish i s turned i nto several grades of useful m ateri al, such as “ferti li zer” for the fi el ds and “soul” for deserts. N othi ng i s wasted, and everythi ng, even pl asti c bags, i s recycl ed. A great idea, i sn’t it? I stared at the moving m odel of the waste machine, absorbed by i ts efi ciency. But agai n we moved on. G: Our thi rd stop shows the changes that have happened to work practices. Manufacturing no longer takes place on the earth but on space stations l ike thi s one.
