Unit 13 We’re trying to save the earth!要点详解1. We’re trying to save the earth!我们正尽力拯救地球！(1) 本句时态为现在进行时，表示现阶段正在做的事情。
现在进行时所表示的动作并不一定在说话人的说话时刻进行，而是在包括说话时刻在内的一段时间当中进行。
例如：George is translating a book now. 乔治现在在翻译一本书。
（说这句话时，乔治不一定正在翻译；但在包括“说话时刻”在内的一段时间当中，乔治是在从事翻译工作。
）(2) try to do 表示“设法或尽力去做某事”，实际上做与不做，视情况而定，而try doing表示“试着做”，即动作真的进行了或正在进行，成败则视结果而定。
例如：He tried to read, but he was too tired to read much.他想设法看书，但太疲倦了，没看多少。
He tried reading, but that could not make him forget his trouble.他试着看书，但这并没使他忘记烦恼。
2. I am like this animal because I am strong and intelligent.我像这种动物，因为我强壮而聪明。
(1) like在本句中做介词，意为“像”，例如：He looks like winning the race.他看来要在比赛中获胜。
She is like her mother.她像她的妈妈。
(2) like做介词时可用very，very much，rather，quite等副词修饰。
例如：You look very much like your father.你与你父亲很相像。
3. Some of the swamps have become polluted。

You can call me Christa.How is it possible that I can hear you, Mongy？”“You wanted to get to know nature and the living things in the world, and you started paying attention to nature.Most people never pay attention to nature, so they only listen when they are young.But you heard the voices of nature calling you.You went even further than that and you tried to get along well with nature.That's why you can hear me now.”It was at this moment that my life changed and I suddenly knew what my destiny (命运) would be from that day on.( )1.The writer was________ when she heard the strange noise.A．driving down a mountainB．checking her carC．looking at a frogD．talking to a frog( )2.The writer found the frog ________.A．on the dirty roadB．in her backpackC．in the forestD．under her car( )3.The writer looked at the frog with her mouth open because________.A．it was making a strange noiseB．it looked at her like a humanC．it answered her in the voice of a frogD．it loved to travel( )4.The writer could hear the frog for all of the following reasons, EXCEPT because ________.A．she wanted to get to know natureB．she paid attention to living thingsC．she tried to get along well with natureD．she had a special ability to talk to frogs( )5.What does the writer want to tell us?A．What her unusual day was like.B．About her special ability to talk with frogs.C．To protect small animals.D．To build a friendly relationship with nature.BA large part of China experienced larger amounts of smog (雾霾) than usual and the air was badly polluted.The distance one could see was shorter than 1,000 meters in Beijing, Tianjin, and the provinces of Hebei, Henan, Shandong and Anhui.In some areas, it was down to 200 meters.People usually set off firecrackers (爆竹) to celebrate the Spring Festival.But because of the smog, this year seemed very quiet.It was really different.A man called Zhang Wei said that his friends and he hadn't set off a single firecracker.“We all suffered from last month's smog.If we don't call an end to the firecrackers, the environment will get worse and worse during the holiday.” Said Zhang Wei.He called on more people to set off fewer firecrackers during this year's Spring Festival holiday by putting up a notice in his neighborhood.More Chinese looked forward to celebrating the holiday in a greener way.They decided not to set off firecrackers.They also decided not to waste food.They said that the new celebrations sounded fashionable.To clean the sky, more than ten provinces including Guangdong, Zhejiang and Jiangsu have started to use national 4 standard (标准), which is expected to reduce (减少) vehicle emission (车辆排放) by 30% to 50%.Beijing even has started to use the stricter national 5 standard.We still have a lot to do to improve the air quality.For example, using public transportation as much as possible is not a hard thing for us to do, but it matters a lot.( )6.What happened in a large part of China this January?A．It experienced larger amounts of smog.B．People set off lots of firecrackers.C．There was a heavy rain.D．Many car accidents happened.( )7.How do people usually celebrate the Spring Festival in China?A．By putting up a noticeB．By setting off firecrackers.C．By not wasting food.D．By using public transportation.( )8.How many provinces have started to use national 4 standard?A．Three.
