“This morning, it took me 40 minutes to go downtown.

Part 1
We know that cars are bad for us. But we all make excuses: “The buses are terrible”; “The trains are always late”; “I haven’t got time to walk”. I’m talking about myself, too. To be frank, I’m addicted to my car. When I asked a friend working for a green-living organization for advice about how to give up, she told me five things:
对…有害

放弃
我们知道汽车带来的危害，但总能找到借口:“公共汽车很糟糕”“火车总是晚点”“我没有时间走路”。我也在说我自己。坦率地说，我离不开车。当我向一位在绿色生活组织工作的朋有寻求关于如何放弃车的建议时，她给了五条建议：
● Use your legs. In 2014, over 55% of car journeys were under eight kilometres. Instead of taking short car journeys, we could easily walk or cycle. Leg power can save your money, keep you fit and help you live longer. Regular exercise also cuts the risk of heart disease by 50%!
走路。2014年，超过55%的汽车行程不到8公里。可以轻易地用走路或骑行来代替短途的开车出行。利用脚力行走可以省钱，保持健康并帮助延长寿命。经常锻炼也能降低50%患心脏病的风险！
汽车出行
代替，而不是
保持健康
了
降低……的风险
● Use public transport. Up to 90 people can travel in one bus, while the same number will need at least 18 cars. Sometimes it can take a little bit longer, but so what You can relax, read a book, talk to someone—who knows
使用公共交通工具。一辆公共汽车可以乘坐90人，而乘坐小轿车这些人至少需要18辆。有时坐公共汽车可能需要更长的时间，但那又怎样？你可以放松一下、读一本书、和别人交谈——谁知道呢
“而”表对比
指“乘坐公共汽车”
talk to sb与某人交谈
至少
一点
● Think before you go. Do you really have to go to that shopping centre on the other side of town What about the shops around the corner Before you get into your car, think about whether you really need to make that journey.
另一边的
在附近，在拐角处
进入
出发之前先想想。你真的要去镇上另一边的那个购物中心吗？拐角处的商店怎么样？在上车之前，想想你是否真的需要开车去那个地方。
…怎么样
whether引导宾语从句 “是否”
Share cars. If you really have to use a car, share journeys with someone else. It is much cheaper and kinder to the environment.
共享汽车。如果不得不用车,与其他人共用一辆车。这样更便宜,也更环保。
much 修饰比较级
1.Sharing journeys with someone else by car is less expensive and more environmental friendly. (T or F)
T
Take action! We often think there is nothing we can do about the noise, pollution and danger of traffic. There is. If your street is full of heavy traffic, talk to your neighbours about it. Write to the papers. Go to the city government. Ask for a speed limit. Do whichever of these things that suit you. Don’t just sit around and complain!
采取行动！我们经常觉得面对噪音、污染和交通危险，自己无能为力。其实可以有所为。如果你那条街的交通繁忙，去和邻居们谈谈，向媒体反映，去市政府，申请设置限速。做你能做的任何事情，别光坐在那里抱怨！
