【題目】蘭州市規(guī)劃生態(tài)綠地以南北兩山森林公園和郊野公園為主體，形成城市生態(tài)綠地系統(tǒng)。據(jù)次完成下列小題。

【1】夏季人們喜歡去蘭山公園休閑度假的原因之一是（　�。�

A. 氣溫比市區(qū)低B. 物價比市區(qū)便宜C. 交通比市區(qū)方便D. 便于野炊

【2】下列行為符合蘭州市生態(tài)綠地規(guī)劃的是（　　）

A. 在林區(qū)開墾耕地，種植糧食B. 在林區(qū)修建高檔私家別墅

C. 保護林區(qū)植被D. 在林區(qū)修建中央商務區(qū)

【答案】

【1】A

【2】C

【解析】

【1】夏季城市因大量的人工發(fā)熱、建筑物和道路等高蓄熱體及綠地減少等因素，使得城市“高溫化”。城市中的氣溫明顯高于外圍郊區(qū)和森林公園。因此夏季人們喜歡去蘭山公園休閑度假的原因是公園的氣溫比市區(qū)低。故選A。

【2】在林區(qū)開墾耕地，修建高檔私家別墅和中央商務區(qū)會破壞林區(qū)的生態(tài)環(huán)境，都不符合蘭州生態(tài)綠地規(guī)劃；保護林區(qū)植被符合蘭州市生態(tài)綠地規(guī)劃，故選C。

本題考查森林的生態(tài)作用。

【題目】 Learning about the environment is very important. There are many good books that will help you learn. To get started, ask your teacher or a librarian for some suggestions. You can also look at some good websites with information about the environment and climate change. Climate change may be a big problem, but there are many little things we can do to make a difference.

Driving a car or using electricity is not wrong. We just have to be smart about it. Some people use less energy by carpooling . For example, four people can ride together in one car instead of driving four cars to work. Whenever we use electricity, we put greenhouse gases (氣體)into the air. By turning off lights, the television, and the computer when they aren't needed, you can help a lot.

Don't buy products that use too much energy. Some products, like certain cars, are made specially to save energy. These cars can travel longer on a smaller amount of gasoline. They don't pollute as much, either. Products like computers, TVs, and VCRs with the ENERGY STAR label (標簽) are made to save energy. Buying products with these labels will help protect the environment. Buy recyclable products instead of non-recyclable ones. Recyclable products are usually made out of things that have already been used. It usually takes less energy to make recyclable products than to make new ones. So when you go shopping, look for the recycle mark on the package-three arrows that make a circle. The less energy we use, the better.

【1】The passage is mainly written for .

A. car producersB. school studentsC. parents

【2】The underlined word “carpooling” in Paragraph 2 most probably means .

A. turning off the electricity when it isn't needed can save a lot of energy

B. electricity will cause great trouble to our environment
