Section Ⅰ Reading and Thinking （1） 阅读理解 A Automaker General Motors （GM） has announced the expectation of achieving carbon neutrality （碳中和） by 2040.On the way to that goal，the company hopes to get rid of automobile emissions （排放物） by 2035. GM said it will take a science-based approach to become carbon neutral，balancing carbon dioxide emissions.Furthermore，it plans to remove gas-powered vehicle production by 2035. ———General Motors is joining governments and companies around the globe working to establish a safer，greener and better world，” said Mary Barra，GM chairman and CEO.“We encourage others to work together and make a significant influence on our industry and on the economy as a whole.” Transportation is the largest contributor of greenhouse gas emissions in the United States， just over 28%，the Environmental Protection Agency reported.That is why GM and other industry leaders have joined the Science Based Targets initiative，which calls on businesses to take action to do with climate change. A clear step for GM to become carbon neutral is to switch from internal combustion engines to electric vehicles.Traditional gas vehicles make up about 75% of GM’s greenhouse emissions，the company said.Their production facilities make up the other 25%，but the manufacturer aims to control the ratio （比率） by using wind and solar energy.GM said it will power its US factories with 100% renewable energy by 2030 and globally by 2035. The bigger obstacle falls on the consumer.An electric vehicle is significantly more expensive.The Natural Resources Defense Council （NRDC） says the average electric car costs $19，000 more than a gasoline-powered car.But GM has spent years improving its battery technology.Maybe that’s the reason why it can get rid of automobile emissions in 2035 with much confidence. 1.What measure is GM taking to achieve the goal of removing carbon dioxide emissions？（ ） A.Working with global organizations. B.Cutting back on battery-powered cars. C.Gaining industrial and financial support. D.Reducing production of cars powered by gas. 2.What is Mary Barra’s attitude towards GM’s carbon neutral approach？（ ） A.Supportive. B.Opposed. C.Critical. D.Indifferent. 3.According to the passage，what results in the greenhouse gas emissions in the US to a large extent？（ ） A.Renewable energy. B.Fast food. C.Transportation. D.Electric vehicles. 4.Which of the following best explains the underlined word “manufacturer” in paragraph 5？（ ） A.Consumer. B.Environmentalist. C.Producer. D.Advertiser. B Global warming is the increase of the earth’s average surface temperature due to the effect of greenhouse gases，for example，carbon dioxide， which traps heat that would otherwise escape from the earth.After the trees are cut down and more greenhouse gases are released，the “blanket” around the earth called the ozone layer （臭氧层），will get thicker.This catches more heat ... ...
