⑦在我看來(lái), 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

青蒿素治療瘧疾效果顯著，是抵抗瘧疾耐藥性最好的藥物。中國(guó)發(fā)現(xiàn)青蒿素時(shí)，美國(guó)也研制出一種抗瘧新藥—化學(xué)合成的甲氟喹，但瘧原蟲很快就適應(yīng)了它，產(chǎn)生耐藥性，臨床使用后患者還出現(xiàn)了明顯的不良反應(yīng)。而對(duì)于青蒿素這種從中草藥中提取的藥物，瘧原蟲對(duì)它完全沒(méi)有抵抗能力。1976 年1月，柬埔寨爆發(fā)瘧疾，因瘧原蟲已經(jīng)產(chǎn)生耐藥性，疫情一時(shí)難以控制。中國(guó)醫(yī)療隊(duì)攜帶一批青蒿素在柬埔寨大顯神威，挽救了一大批瘧疾患者的生命。

①2014年年中，世界衛(wèi)生組織（WHO）公布了《2013年全球氣候狀況報(bào)告》。報(bào)告顯示，2013年全球陸地和海洋表面平均溫度為14．5℃，比1961-1990年的平均溫度升高0．5℃。自有溫度記錄以來(lái)，全球14個(gè)最熱年份中有13個(gè)出現(xiàn)在本世紀(jì)，而過(guò)去30年中每個(gè)10年都比前十年更熱。②厄爾尼諾是發(fā)生在熱帶太平洋上海溫異常增暖的氣候現(xiàn)象，大范圍熱帶太平洋增暖會(huì)造成全球氣候變化。進(jìn)入20世紀(jì)70年代后，全球出現(xiàn)的異常天氣，都有范圍廣、災(zāi)情重、時(shí)間長(zhǎng)等特點(diǎn)，而在這一系列異常天氣的背后，厄爾尼諾暖流都起著重要作用。
