Our efforts will (有影响).二、Arctic ice has reformed rapidly this winter after a record summer low, but it still covers less of the Arctic Ocean than it did decades ago. March is the month when Arctic sea ice traditionally hits its highest extent after the Northern Hemisphere winter and Antarctic sea ice reaches its lowest extent.Arctic sea ice reached a record low this past summer, with 23 percent less sea ice cover than the previous record low and 39 percent less than the average amount that has previously spanned the Arctic Ocean in the summer months.The area of ocean covered by sea ice isn’t the only factor in the “health” of the Arctic ice. Arctic sea ice comes in two types: older, thicker perennial ice that has survived at least one summer melt season and younger, thinner seasonal icethat forms in winter and melts again in summer. Seasonal ice melts more easily because it’s thin and salty, and so it’s easily affected by winds and currents.Lower temperatures in parts of the Arctic increased the amount of thin, seasonal ice that formed this winter. So while Arctic sea ice was dominated by perennial ice in the past decades, it's mostly now younger, newly-formed ice. But because the majority of the ice is young and thin, it would be more susceptible to summer melting.Some of the seasonal ice could become perennial sea ice if summer conditions are cooler than normal. But, one cold summer isn’t going to do it and one cold winte r isn’t going to do it. Numerous years of lower temperatures would be needed to restore the Arctic sea ice to where it was in the 1980s, and that isn't likely to happen with the increasing levels of heat-trapping greenhouse gases in the atmosphere.1.What might excite the scientists concerned with Arctic ice?A.Perennial sea ice was increasing rapidly.B.Arctic ice was disappearing for the time being.C.The area for the Arctic ice was increasing.D.Arctic sea ice hits its lowest extent in March.2.According to the text, what mostly affects the health of the Arctic ice?A.The area of the Arctic sea ice.B.The perennial ice.C.The seasonal sea ice.D.The Antarctic sea ice.3.According to the text, we know that the perennial sea ice _________.A.is not only thick but also saltyB.mainly stays on the islands in the ArcticC.can be made out of the seasonal iceD.covers less sea in winter than in summer4.The underlined word “susceptible” in the fourth paragraph means________.A.easily influencedB.difficultly movedC.easily brokenD.easily impressed三、请根据下面这幅漫画写一篇100词左右的英语短文。

Unit 4 Global warming(教师用书独具)WHAT CAN WE DO ABOUT GLOBAL WARMING?Dear Earth Care，I am doing a project on behalf of my school about global warming．Sometimes I feel that individuals can have little effect on① such huge environmental problems．However，I still think people should advocate improvements in the way we use energy today．As I'm not sure where to start with② my project，I would appreciate any suggestions you may have．Thank you!Ouyang Guang关于全球变暖，我们能做些什么呢？亲爱的“关爱地球”组织：我正代表学校做一项关于全球变暖方面的课题研究。
有时候我觉得，像这样一个巨大的环境问题，个人是起不了什么作用的。
然而我仍认为人们应该倡导改善日常能源的消耗方式。
由于我还不清楚该从哪里着手开始我的研究，我希望能得到你们的建议。
谢谢！欧阳光Dear Ouyang Guang，There are many people who have a commitment like yours ③， but they do not believe they have the power to do anything to improve our environment．That is not true．Together，individuals can make a difference④． We do not have to put up with pollution．The growth of the greenhouse gas，carbon dioxide in the air actually comes as a result of many things we do every day．Here are a few suggestions on how to reduce it．They should get you started with your project．亲爱的欧阳光：有许多人承担你这样的义务，而他们不相信自己有能力来影响环境。
Unit 4 global warming writing
In the video,
what is happening to the sea level? What caused Global Warming It is _________. going up these problems?
A sample: •
Various things can be done to help solve the global warming. In my opinion, leading a low-carbon life is what everyone can do. For example, when going to school, we can walk or use a bicycle when possible and choose public transport such as buses and the underground if travelling long distances. Besides, we should turn off the lights and any other electrical appliances when not in use. Last but not least, we can plant trees, because trees absorb the carbon dioxide in the air to produce oxygen.
Homework:
Writing
• Edit your paragraph. Check spelling, grammar and verb tense. • Double-check the relevance of any details. Read it aloud to yourself or to a friend. Make sure it's clear.
