Trees being cut down; strong winds blowing the valuable soil away.
Plant more trees and try to protect them.
Air is being polluted.
Factories, power stations and cars produce a lot of waste.
A lot of things have to be done to reduce pollution. New laws should be passed and people should realize how serious the problem is.
A lot of people died from polluted air in both Russia and India.
There were serious accidents that polluted the air.
Trees in the forest are destroyed and fish in the lakes are killed.
In some places it’s no longer safe for swimming, nor is it safe to eat the fish.

8).如果直接引语是以would like 作谓语的特殊疑问句，间接引语中would like 不变；如果直接引语是一般疑问句，like 之后接动名词或名词作宾语，间接引语中would like也不变。
2.直接引语是祈使句变间接引语，通常将say 改为ask 或tell, order等词，构成ask (tell, order) sb. to do sth.结构。原祈使句如果是否定的，要在不定式结构前加not，原祈使句中如果带有please一词，间接引语也不再使用。
例如：‘Please open the second window,’ he said. He asked me to open
the second window.
例如：She said, “What a lovely day.” She remarked with joy that it was
such a lovely day.
The Summer Holiday
1. The students should master the following important vocabulary:
introduce, practice, vacation, employ, regards, expression, physics, chemistry, biology, geography, go away, in one's opinion, general idea, go on doing, as a result
2. The students should know the meaning of the following useful expressions and besides that they should know how to use them in their daily life.

(2) Nice to meet you. / Nice meeting you.

(4) Give one's regards / best wishes / love to sb.
(5) That's nice/ kind of you.
(6) See you soon. / See you later. / See you tomorrow.
2. The students must grasp the following sentence structure.
(1) So + be/ have/ 助动词/情态动词+ 主语
It's one's turn to do sth.
The students are supposed to talk about their summer holidays with the beginning of introducing themselves. Then they can make a survey to get to know what they all have done in the holiday in the form of group ( which contains 4-6 students).
This lesson is the first lesson of the new term. And the most important point is that it is the first time that the students have met each other. So this is a good chance to get to know each other by introducing themselves. Meanwhile, the teacher can also get to know the students' ability to speak English. The teacher may teach the students how to greet and how to let others know you. Also, the students must have a lot of different experiences during the long summer holiday. Therefore, it is a good chance for them to understand what they each do during the holiday. The teacher can ask the students some general questions about their summer holidays. Such as, Did you enjoy your summer holidays? What did you do during your summer holidays? Where did you go in the holidays? Then the students can have group work or pair work---- they exchange their ideas about their summer holidays. The students ( in the form of group )can make a survey about their experiences. And then each group may choose one group leader to give the whole class a report about their group's summer holidays. The group leader may introduce it by using the third person. For example:
"Mary went to
The survey is based on the questions of Part Two of the first lesson. The students can also ask some other questions if like. Or the teacher may ask the students to bring some photos that they took in the summer holidays and them show the photos to other students and explain what the photos were about. The teacher may set an example to the students first by showing her/his photos to the students and them the students may know what they are supposed to do.
After the introduction the students may play a game--- who can recall the other students' names and the student who can name the most students' names is the winner.
1．区别Nice to meet you 和 Nice meeting you这两个词组的意思都是“很高兴见到你”。
区别是Nice to meet you用的是一个不定式。而不定式的作用是表示将要做的事情，所以这个词组常常在刚一见面时说。
Nice meeting you用了一个现在分词在此表示完成的动作，所以它常常用在谈话结束时或分手之前。同样我们也可以说：
Nice to talk with you. Nice talking with you.
Glad to have you here. Glad having you here.
2。So+ be/ have/ 助动词/情态动词+主语 与so+ 主语+ be/ have/助动词/情态

(4)---John can sing songs very well.--- So can I . (我也能唱的很好)

She always studies very hard and helps others with their homework.
(1) --- I guess the book must be borrowe by John.

(2) --- She did the job successfully.
--- So she did. 是的，她的确做地很成功）And she was praised by the others in her company.
如果表示某种情况也同样不适用于另外一个人或物， 要用“Neither / Nor + be/ have / 助动词 / 情态动词 +
(1) --- He has never been to Beijing.--- Neither / Nor have I . 我也没有去过）
I really wish to go there some day in future.
(2) --- I can't swim across the wide river.--- Neither / Nor can my sister. (我妹妹也不能)
3．辨析too much & much too

Teaching Plan for Lesson One
Step 1 Lead in questions
Introduce yourself to the class by saying " Hello everyone. I'm very happy to be your new English teacher this term. Do you like English? I am sure that we can become good friends and I will try my best to help you speak English well. Do you want to speak English as well as the native speakers? So you must study hard and do what I will tell you to do. Now I'd love to introduce myself to you so that we can become friends very quickly. My name is ……and it is really nice to see you. Now I would love you to introduce yourselves to us. In your introduction you have to tell us what your name is and what middle school you come from and then tell us what you are interested in or what you are good at. (The students can do this task one by one in a very short time.)
Step 2. Listen to the dialogue
Do you want to make new friends when you come to a new school? Suppose you and a classmate of yours meet at the school gate for the first time at the beginning of the new term. But you don't know each other. So you will have a talk with each other in order to go to the classroom together. And maybe you and her/him will become very good friends later on.
Ask the students to listen to a dialogue that happens in such a case in order that they can know what they should say for the first time two people meet.
The students should find out the answers to some questions that the teacher shows them:
(1) Were Bill and Harry at the same school last year? ( No)
(2) Did Harry know Bob? ( Yes )
(3) How do you know it? ( They were in the same class )
Step 3. Listen to the second dialogue
Ask two students to come to the front of the class. Get to know their names by asking " What is your name ? " Then the teacher will point to these two students and speak to the whole class, " I am very glad to introduce you my new friends. This is Mary and this is John. "The students are then supposed to ask these two students some questions to get more information about them. Then let the students listen to the second dialogue which teaches the students how to make an introduction.
Step 4. Practice
The students are supposed to do group work---- four students make a group and each of them give a brief introduction about themselves. After they get to know each other they are supposed to ask and answer some questions about their summer vacation. The teacher may set an example----the teacher may let the students to then ask them some questions about her/ his summer holidays.
The questions can be:
What did you do during your summer holidays?
Did you enjoy your summer holidays?
Where did you go and who went with you ?
Then the teacher may answer these questions and put the above questions on the blackboard for the students. Then it is the students ‘ turn to practise.
The teacher may give the students five minutes for this task. The students are supposed to make a survey----every group chooses a leader who may write down all the answers and then in the end the group leader is asked to give a talk about the group members’ summer holidays.
“Mary stayed at home the whole summer holidays because she had to look after her mother. John went to some places of great interests and he enjoyed his summer holidays. Mike ┅┅”
