Go through the article
1. Answer two questions
1) Where is Zhalong Nature Reserve?
2) What kinds of animals live there?
2. Guess the meanings of some new words.
             Zhalong-a special place
Zhalong Nature Reserve is in Heilongjiang Province in north-east China. It is one of the world's most important wetlands. The area provides food and cover for a lot of wildlife. It is a perfect place for some rare birds.
   (Paragraph 1: About Zhalong Nature Reserve)
Many birds live in Zhalong all year round, while some go there only for a short stay. Most birds are active in the daytime, so you can easily watch them there. There are not many cranes left in the world, and 40 percent of them live in Zhalong.
   (Paragraph 2: About birds in Zhalong)
Some people want to make the wetlands smaller in order to have more space for farms and buildings. This will lead to less and less space for wildlife. Moreover, fishermen keep fishing there. As a result, the birds do not have enough food to eat. Now the Chinese government has made laws to prevent all these things in Zhalong.
   (Paragraph 3: Birds in Zhalong are in danger.)
Once a year, the members of our Birdwatching Club go to study the birds in zhalong. We record their types and changes in their numbers.
Every year, a lot of tourists go to Zhalong to watch the birds. We are now inviting them to help us. We need more people to count and describe the birds. We hope this will help people understand the importance of the wetlands.
   (Paragraph 4: What the Birdwatching Society members do.)
   (Paragraph 5: Most people can help count and describe the birds.)

动词不定式
不定式由“to+动词原形”构成，其否定形式是“not/never to do”，不定式可以带宾语或状语构成不定式短语，没有人称和数的变化，但有时态和语态的变化。不定式可以作主语、宾语、状语、表语、定语和宾语补足语，但不能单独作谓语。
不定式结构作状语
不定式结构可以作状语，修饰动词、形容词、副词等，表示目的、原因、结果、条件等。
1、表示目的：
They ran over to welcome the delegates.
He bought a bicycle to go to town more quickly.
He went home to see his mother.
注①：不定式结构表示目的时，通常句子的主语就是它的逻辑主语（参见以上三句），但也有例外的情况，例如：
  I stopped for him to speak to me.
  He opened the door for the children to come in.
  He brought a porter to carry the boxes/bags.
  They sent a man to mend the window.
  He stood up to be seen better.
注②：为了强调表示目的的不定式结构，特别是在不定式结构前有否定词not时，通常可以在不定式符号to之前加上in order或so as，如：
  He came here in order to see Charlie.
  He shouted and waved so as to be noticed.
  He went early in order not to miss the train.
  I turned the radio down so as not to disturb him.
注③：表示目的的不定式可以置于句首，这也是区别于其他功能的标志之一。但是，置于句首表示目的的不定式之前可以加上in order，但却不可以加上so as，如：
  To draw maps properly, you need a special pen.
  (In order to draw maps properly, you need a special pen.)
  To get the best results, use clean water.
不定式结构作宾语补足语
Don't force yourself to write when you have nothing to say.
He believed the earth to be a globe.
Did you see a young man enter the house?
1、只能用不定式结构作宾语补足语的动词：
①表示“希望”“愿望”等心理状态的动词，如：wish，desire，expect，love，prefer，encourage，trust等。
What do you desire me to do?
The director preferred her to act the old lady.
②含有“让”“允许”“促使”“致使”等祈使意义的动词，如：let，allow，permit，decide，mean，lead，bring，put，hurry，cause等。

His father put him to mind the sheep.
③带有“请求”“恳求”等感情色彩的动词，如：ask，desire，invite，beg，request，worry等。
He begged me not to tell his father about it.
She was always worrying her father to take her to Paris.
④含有“建议”“劝告”等意义的动词，如：advise，persuade，call on，urge等。
