(check)common ideas and opinions to see what’s really green. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ( 家庭作业 ) Ⅰ.阅读理解 Bees may soon need to add protein shakes to their diet.Pollen(花粉) normally provides their protein(蛋白质).But rising levels of carbon dioxide(CO2) in the air have reduced the protein in pollen.That’s what a new study finds. Scientists compared recently collected flowers from Canada goldenrod.Then they compared pollen in them to pollen in goldenrod reserved at a museum in Washington，DC.They found today’s plants have less protein.Protein levels in pollen from the older flowers were 18 percent.Today’s goldenrod pollen has only about 12 percent protein.That’s about one-third less than 172 years ago.Over that same period，CO2 levels have gone up by more than one-third.Back more than 170 years ago，they were about 280 parts per million in air.Today they are about 398 ppm. To test whether CO2 changes had played a role in the falling protein levels，the researchers did some tests.They grew goldenrod for two years at CO2 levels of up to 500 ppm.More CO2 in the air led to lower levels of protein in the flowers’ pollen. Joan Edwards，one of the researchers，says that this drop in pollen protein could affect a bee’s diet and health.It would be like eating junk food，tasting good but offering less nutrition(营养). Honeybees need to eat lots of protein.They use it to feed their young.They also need it to keep their immune systems healthy，says Cédric Alaux，a bee biologist at the French agricultural research agency. Bee populations have been decreasing worldwide in recent years.A drop in their food quality might play a role，Edwards says.And that drop might affect crops too.“The health of the bee population is not just for the flowers and the bees and biodiversity.” She worries it also could play a role in “human health and well-being.” 1.The second paragraph is mainly developed by . A.giving examples B.following the time order C.explaining reasons D.providing numbers 2.According to the text，Joan Edwards might agree that . A.the drop of protein in pollen has a good influence on bees B.today’s flowers can provide bees with enough nutrition C.the drop of protein in pollen leads to a smaller population of bees D.the smaller population of bees has nothing to do with the human race 3.What is the main idea of the text? A.Today’s flowers contain more protein. B.Protein levels in pollen connect with CO2 levels. C.Drop of protein in pollen affects bees. D.Bee population is becoming smaller recently. Ⅱ.七选五 Some years back，nobody paid much attention to the waste in homes and landfills.It became so vast that the government started getting concerned the phenomenon could create a disaster.A solution had to be found，but one that is kind to humans and the environment. 1 .Below are the reasons why we need to recycle. Conserve natural resources 2 .If a lot of pressure is put on these natural resources，they might be run out of fast.The only way to stop the pressure applied to these resources is recycling.According to the United States Environmental Protection Agency，recycling one ton of paper saves up about 17 trees as well as 7 tons of water. Reduce carbon emissions Recycling greatly minimizes carbon emissions，commonly referred to as greenhouse gases. 3 ，they would end up being burned，giving out dangerous greenhouse gases.Whatever your opinion on global warming，a lot of people agree to the idea that everyone needs to play a role in minimizing the effects of pollution and emissions. 4 Recycling has been proved to save up lots of energy.Companies that use recycled aluminum save up to 95% energy during production of aluminum products when compared to companies that source raw materials. One person can make a big difference Most people have already made up their minds that one person cannot make any difference in regard to recycling waste.That thinking might apply in other fields.In recycling，an individual can make a big difference.Averagely，every American produces about 1，600 pounds of waste every year.Up to 1，100 pounds of waste is able to be recycled every year per person. 5 . ( A.Save energy B.Protect the environment C.That’s how recycling was born D.If these wastes were not recycled E.That represents half a ton per individual F.Many kinds of resources are considered limited G.You and your neighbor’s effort to recycle will mean clean surrounding air ) Ⅲ.完形填空 As far back as I can remember，I always loved being outdoors.Exploring the outdoors or just going for 1 in the park has always made me feel happy and 2 . Nowadays，we， 3 younger generations，spend so much time 4 that it seems the digital world is more valued and important than the 5 one.Nature is something that I feel is underappreciated.Not only is it one of the most powerful and complex systems on earth， 6 it’s one of the most interesting—look 7 and you will see that everything has its place and purpose. As I get older，I find my life is becoming more 8 and fast paced，which is why I love to 9 back to nature and believe being outside 10 by it is good for the soul.Step outside，and you’ll see the circle of life 11 right in front of you.Plants and animals live and die to make 12 for the next generation—just as humans are mortal，so is nature，there are no 13 to that rule.When we spend time in nature，we are reminded that 14 is fleeting，so we need to remember to live fully in the 15 .Nothing is permanent，and that’s 16 makes life so precious.
