世五维课堂 空 英课时 间 3.Learnin 纠错空间 语作业 I.阅读理解 Over a hundred years ago in 1911, something strange was found in the glac- iers of Antarctica.Crilffith Taylor-an Australian geologist,had discovered a blood red stream pouring out of the ice cascades(瀑布)of Talor Glacier.Popu- larly known as the Blood Falls,scientists had not been able to find the reason be- hind the blood red liquid flowing through the ice until recently.The mystery of the Blood Falls had finally been solved. 方法总结 When these falls were first discov- ered,scientists had believed that the red colour came from a large amount of red algae(海藻)concentrated in the water.. Red algae contain a pigment(色素)which re- flects red light,making the algae appear red. This theory made sense,until it was later found that algae do not play a part in the red colour of the flowing liquid at all. What really causes Talor Glacier's water to appear blood red is the presence of iron oxide in the liquid.The waters of the Blood Falls are rich in salt and iron con- tent,and when this water comes in con- tact with the air,it turns red-just like rust!The water in these falls is often re- ferred to as“brine”by scientists because of the high salt content in the water. ·208 英语·选择性必修第三册 ng About Language This reasoning behind the red colour of the falls was found back in 2003. However,the entire mystery had not yet been solved.How is it then,that the Blood Falls are not frozen? Researchers at the University of Col- orado and University of Alaska found that inside the glacier,there is a network of channels and reservoirs that moves the water around.Salt water has a lower freezing temperature.In addition,when any substance undergoes a change in state,it gives off heat.Therefore,the brine actually warms itself up while it's freezing!How this works is that when the brine is flowing through the Talor Glacier,some of it does freeze.As a re- sult of changing state from liquid to ice, the brine gives off heat.This heat is enough to keep the rest of the brine in liq- uid form,which is why it flows out of the glacier. Incredible new chemistry facts found, and mystery solved！ 1.According to the text,the red algae theory was once considered A.ridiculous B.reasonable C.impractical D.complex 2.Why does the Blood Falls look red in colour? A.There is too much salt and iron in its water. B.Its liquid is rich in red algae. UNIT 3 ENVIRONMENTAL PROTECTION C.The flowing liquid reflects red sun- light. D.The air is thin and rare in Antarctica. 3.What is the main reason for the Blood Falls'not freezing? A.The water continued flowing con- stantly. B.There is too much salt in the water. C.The brine gives off heat while freezing. D.Temperatures aren't high enough for flowing water. 4.What is the passage mainly about? A.The discovery of the blood glacier. B.The birth of the Talor Glacier. C.The flowing red water in Antarctica. D.The mystery of the Blood Falls. Ⅱ.阅读填句 Solutions to Climate Change There are personal lifestyle changes that you can make and that,to some ex- tent,can help reduce your carbon impact. Not all are right for everybody.But ap- plying just a few of them could make a difference. Move closer to work. Transportation is one of the leading sources of greenhouse gas emissions.1 One way to dramatically cut transporta- tion fuel needs is to move closer to work, use mass transportation,or switch to walking,cycling or some other modes of transport that does not require anything other than human energy. Consume less. 2 Whether by quitting an auto- mobile or employing a reusable grocery ·209 课时作业乡 sack,cutting back on consumption re- sults in fewer fossil fuels being burned to 间 extract,produce and ship products 纠错空间 around the globe. 3 A potentially simpler and even bigger effect can be produced by doing more with less.Citizens of many developed countries are energy-wasters,whether by speeding in a gas-wasting vehicle or leav- ing the lights on when not in a room. Similarly,employing more efficient refrig erators,air conditioners and other appli- ances can cut electricity bills.4 You can turn the lights or your computers off when you leave the office. Stop cutting down trees. 方法总结 When purchasing wood products, such as furniture or flooring,buy used 生1。卡中员中方员行卡中中员 goods or,failing that,wood proved offi- cially to have been sustainably harvested. The Amazon rainforest and other forests are more than the lung of the earth.5 A.Be energy efficient. B.Use few electrical appliances. C.But it doesn't have to be that way. 1++4114+4114441444 D.Such efforts can also be usefully em- ployed at work. E.They may also be humans'short-term hope for limiting climate change. F.The easiest way to cut back on green- house gas emissions is simply to buy less stuff.
