1、　　課 時 作 業(yè)　 29 Ⅰ.閱讀理解 (2019·福建省廈門第一中學(xué)高三月考) There have been claims that warming on Mars and Pluto is proof that the recent warming on Earth is caused by an increase in solar activity, and not by greenhouse gases. But we can say with certainty that, even if Mars, Pluto or any other planet has warmed

2、 in recent years, it is not due to changes in solar activity. The Sun's energy output has not increased since direct measurements began in 1978. If increased solar output really was responsible, we should be seeing warming on all the planets and their moons, not just Mars and Pluto. Our solar syst

3、em has eight planets, three dwarf planets and quite a few moons with at least a thin atmosphere, and thus a climate of sorts. Their climates will be affected by local factors such as orbital variations, changes in reflectance and even volcanic eruptions, so it would not be surprising if several plan

4、ets and moons turn out to be warming at any one time. One theory is that winds have recently swept some areas of Mars clean of dust, darkening the surface, warming the Red Planet and leading to further increases in windiness—a positive feedback effect. Observations of the thickness of Pluto's atmo

5、sphere in 2002 suggested the dwarf planet was warming even as its orbit took it further from the Sun. The finding confused astronomers at the time, and the cause had yet to be determined. It has since been suggested that this is due to a greenhouse effect: As it gets closer to the Sun, Pluto may wa

6、rm enough for some of the methane ice on its surface to turn into a gas. This would cause further warming, which would continue for a while even after Pluto's orbit starts to take it away from the Sun. 本文是一篇科普說明文，有人認為地球變暖是因為太陽活動而不是溫室氣體，文章駁斥了這個觀點。同時對太陽系里另外一些星星的變暖情況分別進行了分析。 1．What cause(s)the warmin

7、g of some planets? A．The solar system. B．Their local factors. C．Volcanic mountains. D．The thin atmosphere. 答案：B 解析：細節(jié)理解題。根據(jù)第三段第二句Their climates will be affected by local factors such as orbital variations, changes in reflectance and even volcanic eruptions可知，導(dǎo)致某些星球變暖的原因很多，可能是受到這些星球的當?shù)匾蛩氐挠绊憽９蔅項正確

8、。 2．What is the outcome of the recent winds on Mars? A．They've cooled the planet. B．They've left a clear sky. C．They've caused more winds.

A．It remains mysterious. B．It troubled astronauts. C．It has become thinner. D．It contributes

10、to the warming. 答案：D 解析：細節(jié)理解題。根據(jù)第五段第一句Observations of the thickness of Pluto's atmosphere in 2002 suggested the dwarf planet was warming even as its orbit took it further from the Sun.可知，冥王星厚厚的大氣層導(dǎo)致了冥王星變暖。故D項正確。 4．Which of the following might lead to the warming on Earth according to the writer?

11、 A．Solar activity. B．Mars and Pluto. C．Greenhouse gases. D．The Sun's energy output. 答案：C 解析：推理判斷題。根據(jù)文章第一段第一句可知有人認為地球變暖是因為太陽活動而不是溫室氣體。根據(jù)第二句But we can say with certainty that, even if Mars, Pluto or any other planet has warmed in recent years, it is not due to changes in solar activity.可知，我們可以確切地

12、說地球變暖不是因為太陽運動，也就是說地球變暖是由溫室氣體導(dǎo)致的。故C項正確。 Ⅱ.完形填空 (2019·濟南一中模擬) I went with some colleagues from my office for a dinner in a very popular local restaurant.

32、about __1__ (them)是賓補，因此feel的邏輯主語是句子賓語them，該空是about的賓語，和邏輯主語一致，就應(yīng)該用反身代詞作賓語。故填themselves。 2．longer　解析：考查形容詞。句意：如果它能在較長時間內(nèi)堅持下去，它就會成為一種趨勢。該句是和前半句的for a little while進行對比，所以此處用比較級。故填longer。 3．harmless　解析：考查形容詞。句意：許多時尚是無害的。此處作句子的表語，根據(jù)句意可知應(yīng)該用形容詞作表語，表示“無害的”。故填harmless。 4．wore　解析：考查動詞。句意：回到我的時代，人們把袖子和領(lǐng)子剪下

34、其是對于那些剛剛起步的青少年家長來說，它值得付出努力。根據(jù)句意可知，此處用副詞especially表示“尤其”。故填especially。 8．started　解析：考查動詞。句意：雖然對青少年時尚的關(guān)注有時會讓家長們感到疲憊，尤其是對于那些剛剛起步的青少年家長來說，它值得付出努力。get started表示狀態(tài)，“剛剛起步的”。故填started。 9．Although/Though/While　解析：考查連詞。句意：雖然你不能選擇你的青少年會選擇的流行趨勢或時尚，但這并不意味著你不能補充你的觀點，并將時尚作為一個可教的時刻。根據(jù)句意可知，上下句之間為轉(zhuǎn)折關(guān)系，后半句沒有but，前半句用
