one seri ous shorti ng. She can be real y stubborn. Al though she di dn39。 t know the best way of getti ng to pl aces, she i nsi sted that she ani ze the tri p properl y. N ow, I know that the proper way is al ways her way. I kept asking her, When are we l eavi ng and when are we i ng back? I asked her whether she had l ooked at a m ap yet. O f course, she hadn39。 t。 m y si ster doesn39。 t care about detail s. So I tol d her that the source of the Mekong i s i n Qi nghai Provi nce. She gave m e a determi ned l ook—the ki nd that sai d she woul d not change her mi nd. When I tol d her that our journey woul d begin at an alti tude of m ore than 5, 000 m etres, she seem ed to be exci ted about it. When I tol d her the ai r woul d be hard to breathe and i t woul d be very col d, she sai d i t woul d be an i nteresti ng experi ence. I know m y sister wel . Once she has m ade up her m i nd, nothi ng can change i t. Fi nal l y, I had to gi ve in. Several m onths before our tri p,Wang Wei and I went to the li brary. We found a l arge atl as wi th good m aps that showed detail s of worl d geography. From the atl as we coul d see that the Mekong Ri ver begi ns i n a gl acier on a Ti betan m ountai n. At fi rst the ri ver i s smal and the water is cl ear and col d. Then i t begi ns to move qui ckl y. It be es rapi ds as i t passes through deep val eys, travel li ng across western Yunnan Province. Som etim es the river be es a waterfal and enters wi de val eys. We were both surprised to l earn that hal f of the ri ver i s i n Chi na. After i t l eaves Chi na and the hi gh alti tude, the Mekong be es wi de， brown and warm . As i t enters Southeast Asi a, i ts pace slows. It m akes wi de bends or m eanders through l ow val eys to the pl ai ns where ri ce grows. At l ast, the ri ver del ta enters the South Chi na Sea. PART2 A NIGH T IN TH E MOUNTAINS Al though i t was autumn, the snow was al ready begi nni ng to fal i n Ti ur l egs were so heavy and col d that they fel t l ike bl ocks of ave you ever seen snowmen ride bicycl es?That’s what we l ooked l ike! Al ong the way chil dren dressed i n l ong wool coats stopped to l ok at us. In the l ate afternoon we found i t was so col d that our water bottl es froze. .H owever, the l akes shonel i ke gl ass i n the setti ng sun and l ooked wonderful. Wangwei rode i n front of m e as usual. She i s very reli abl e and I knew I didn’t need to encourage her. To climb the mountains was hard work but as we l ooked around us, we were surprised by the vi ew. We seem ed to be abl e to see for mi l es. At one poi nt we were so hi gh that we found oursel ves cycl i ng through cl ouds. Then we began goi ng down the hil l s. It was great fun especi al y as i t gradual l y becam e m uch warm er. In the val l eys col ourful butterfli es fl ew around us and we saw many yaks and sheep eati ng gren grass. At this poi nt we had to change our caps, coats, gloves and trousers for Tshi rts and shorts. In the earl y eveni ng we al ways stop to m ake cam p. We put up our tent and then we eat. After super Wang Wei put her head down on her pil low and went to sl eep but I stayed awake. At mi dnight the sky becam e clearer and the stars grew bri ghter. It was so qui et. There was al most no wi nd—onl y the fl am es of our fi re for pany. As I l ay beneath the stars I thought about how far we had al ready travel ed. We wil l reach Dali i n Yunnan Provi nce soon, where our cousi ns Dao Wei and Yu H ang wil l joi n us. We can hardly wai t to see them! PART 6 TH E END OF OUR JOUNEY Cam bodi a was in m any ways simi l ar to Laos, al though i t has twi ce the popul ati on. At another inn, we tal ked wi th a teacher who tol d us that hal f of the peopl e i n her country coul dn’t read or write. H er vil age coul dn’t even afford to buil d a schol, so she had to teach outside under a l arge tent. When we sai d goodbye, we al fel t very lucky to have studi ed i n col ege. Back on the road, we pased betwen m any hil ls and forests. Then we cam e to the pl ai ns and entered Phnom Penh, the capital of Cam bodi a. In m any ways i t l ooked l i ke Vi enti ane and H o Chi Mi nh Ci ty。 i t al so had wi de streets wi th trees i n rows and ol d French houses. Unl i ke Vientiane, shi ps coul d travel the Mekong Ri ver here. In the center of the ci ty we vi si ted the pal ace and a beauti ful whi te el ephant. It can only be seen outsi de the pal ace on speci al days. We ate an earl y supper and went to see a great tem pl e wi th fl oors m ade of sl iver. The next m orni ng our group sl ept l ate. We were very ti red from the l ong bi ke ri de the day before. Cycli ng i n the hil ls had been di fcuil t. Now our coui ns had the chance to m ake jokes about Wangwei and m e. Perhaps, they sai d, they were the strong ones!We had l unch at a ni ce outdor cafe,then rode out of the ci ty. Two days l ater we crossed the border into Vietnam. We began to see many more peopl e,but I wasn’t surprised . I read i n an atlas before our trip that Vi etnam has alm ost seven ti mes the popul ati on of Cam bodi a. We m et a farm er who gave us directi ons and tol d us that he grows a new rice crop four tim es every year so he can feed m ore peopl e. H e al so tol d us that the northern part of hi s country has m any m ountai ns and i t i s much cool er than here i n the south, where i t i s fl at. Al though the fl at del ta made i t easier for us to cycl e. we got warm very quickl y. So we drank lots of water and ate l ots of bananas. Soon the del ta separated into ni ne sm al er rivers. Two days l ater, after we had passed thousands of ri ce fi el ds, we cam e to the sea. We were ti red but al so i n hi gh spi ri ts: our dream to cycl e al ong the Mekong Ri ver had final y e true. Unit 4 A NIGHT THE EARTH DID’T SLEEP Strange thi ngs were happeni ng i n the countri side of northest H eBei. For there days the water i n the vil l age wel s rose。
