文檔簡介
1、a chance to make a trip into space with my friend li yanping, an astronomer. we visited the moon in our spaceship!before we leave, li yanping explained to me that the forece of the gravity would change three times on our journey and that the first change would be the most powerful. then we were off.
2、 as the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earths gravity. it was so hard that we could not say anything to each other. gradually the weight lessened and i was able to talk to him. “ why is the spaceship not falling back to t
3、he earth? on the earth if i fall from a tree i will fall to ground.” i asked. “ we are too far from the earth now to feel its pull, “ he explained, “ so we feel as if there is no gravity at all. when we get closer to the moon, we shall feel its gravity pulling us, but it will not be as strong a pull
4、 as the earths. “ i cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger.when we got there, i wanted to explore immediately. “ come on,” i said. “ if you are right, my mass will be less than on the earth because the moon
5、is smaller and i will be able to move more freely. i might even grow taller if i stay here long enough. i shall certainly weigh less!” i laughed and climbed down the steps from the spaceship. but when i tried to step forward, i found i was carried twice as far as on the earth and fell over. “ oh dea
6、r,” i cried, “ walking does need a bit of practice now that gravity has changed.” after a while i got the hang of it and we began to enjoy ourselves.leaving the moons gravity was not as painful as leaving the earths. but returning to the earth was very frightening. we watched, amazed as fire broke o
7、ut on the outside of the spaceship as the earths gravity increased. again we were pushed back hard into our seats as we came back to land. “ that was very exhausting but very exciting too,” i said. “now i know much more about gravity! do you think we could bisit some stars next time?” “of course,” h
8、e smiled, “ which star would you like to go to?”caught by a black holethe spaceship warned li yanping and me to be ready as we were approaching the “black hole”. we could see some faint lights around what looked like an empty space. li yanping said, “ that empty hole is like a mouth always needing t
9、o be fed. those lights are thins that are being pulled into time by the gravity of the hole.” we watched with interest and amazement at the lights which seemed to be going fainter and fainter round the edge of the black hole. just then the lights on our spaceship went our the and the computer stoppe
10、d working. what was happening? i tried to turn the spaceship away from the hole but it would not move. would it eat us too?suddenly the spaceship jumped and began to move round the edge of trhe hole too. the gravity of the “black hole” was pulling us into its “mouth”. as the spaceship moved round th
11、e black hole, i felt rather sick. my mouth went dry and i closed my eyes. all the stories about what happened when you were caught by the gravity of a “black hole” seem to be true.but then the spaceship jumped again. this time it moved sideways and away from this edge of the “black hole”. someone wa
12、tching me would have seen the spaceship flying like a bird away from the “black hole”. but we felt nothing. at last we were able to look around us. luckily the computer had started working again. we realized that we had discovered something new about “black hole”. if you go inside the edge of a “bla
13、ck hole”, it will “eat” you and there is no escape; but if you do not, you may have an opportunity to escape. how exciting!unit 5a trip on “ the true north”li daiyu and her cousin liu qian were on a trip to canada to bisit their cousins in montreal on the atlantic coast. rather than take the aeropla
14、ne all the way, they decided to fly to vancouver and then take the train west to east across canada. the though that they could cross the whole continent was exciting.their friend, danny lin, was waiting at the airport. he was going to take them and their baggage to catch “the true north”, the cross
15、 canada train. on the way to the statiion, he chatted about their trip. “youre going to see some great scenery. going eastward, youll pass mountains and thousands of lakes and forests, as well as wide rivers and large cities. some people have the idea that you can cross canda in less than fice days,
16、 but they forget the fact that canada is 5500 kilometers from coast to coast. here in vancouver, youre in canadas warmest part. people say it is canadas most beautiful city, surrounded by mountains and the pacific ocean. skiing in the rocky mountains and sailing in the harbour make vancouver one of
17、canadas most popular cities to live in. its population is increasing rapidly. the coast north of vancouver has some of the oldest and most beautiful forests in the world. it is so wet there that the trees are extremely tall, some measuring over 90 metres.”that afternoon aboard the train, the cousins
18、 settled down in their seats. earlier that day, when they crossed the rocky mountains, they managed to catch sight of some mountain goats and even a grizzly bear and an eagle. their next stop was calgary, which is famous for the calgary stampede. cowboys from all over the world come to compete in th
19、e stampede. many of them have a gift for riding wild horses and can win thousands of dollars in prizes.after two days travel, the girls began to realize that canada is quite empty. at school, they had learned that most canadians live within a few hundred kilometres of the usa border, and canadas pop
20、ulation is only slightly over thirty million, but now they were amazed to see such an empty country. they went through a wheat-growing province and saw farms that covered thousands of acres. afrer dinner, they were back in an urban area, the busy port city of thunder bay at the top of the great lake
21、s. because of the great lakes, they learned, canada has more fresh water than any other country in the world. in fact, it has one-third of the worlds total fresh water, and much of it is in the great lakes.that night as they slept, the train rushed across the top of lake superior, through the great
22、forests and southward towads toronto.“the true north” from toronto to montrealthe next morning the bushes and maple trees outside their window were red, gold and orange, and there was frost on the ground, confirming that fall had arrived in canada.around noon they arrived in toronto, the biggest and
23、 most wealthy city in canada. they were not leaving for montreal until later, so they went on a tour of the city. they went up the tall cn tower and looked across the lake. in the distance, they could see the misty cloud that rose from the great niagara falls, which is on the south side of the lake.
24、 the water flows into the niagara river and over the falls on its way to the sea.they saw the covered stadium, home of several famous basketball teams. as they walked north from the harbour area, li daiyu said, “l(fā)in fang, one of my mothers old schoolmates, lives here. i should phone her from a telep
25、hone booth.”they met lin fei around dusk in downtown chinatown, one of the three in toronto. over dinner at a restaurant called the pink pearl, the cousins chatted with lin fei, who had moved to canada many years earlier. “we can get good cantonese food here,” lin feitold them, “ because most of the
26、 chinese people here come from south china, especially hong kong. its too bad you cant go as far as ottawa, canadas capital. its approximately four hundred kilometers northeast of toronto, so it would take too long.”the train left late that night and arrived in montreal at dawn the next morning. at
27、the station, people everywhere were speaking french. there were sighs and ads in french, but some of them had english words in smaller letters. “we dont leave until this evening,” said liu qian. “l(fā)ets go downtown. old montreal is close to the water.” they spent the afternoon in lovely shops and visi
28、ting artists in their workplaces beside the water. as they sat in a buffet restaurant looking over the broad st lawrence river, a young man sat down with them.“hello, my name is henri. im a student at the university nearby,” he said,” and i was wondering where you are from.” the girls told him they
29、were on a trp across canada and that they had only on day in montreal. “thats too bad,” he said. “montreal is a city with wonderful restaurants and clubs. most of us speak both english and french, but the city has french culture and traditions. we love good coffee, good bread and good music.”that ni
