It is the fourth unit of the New Senior English For China Student’s Book 7. It mainly practices the ability of reading and writing of students. The book includes a large number of new words, which are difficult for my students to understand. Therefore, it is important for them to preview the new words and the reading parts.

People who help others in their community or outside their community would be called volunteers. However, they would not be called volunteers if they help their parents, other relatives or friends.
Q2: What do the volunteers usually do to help other people?
A possible version : The volunteers make their greatest efforts to help others.

Step 2 关系代词that 和which的区别 : 1)
2)
3)
Step 3 as, which 非限定性定语从句
as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：　(1) as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思　(2）as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which。
(3)当先行词受such, the same修饰时，常用asI have never heard such a story as he tells.He is not such a fool as he looks.This is the same book as I lost last week.注意：
当先行词由the same修饰时，偶尔也用that引导定语从句，但是和由as所引导的定语从句意思不同。She wore the same dress that she wore at Mary’s wedding. 她穿着她在MARY婚礼上穿过的一条裙子。She wore the same dress as her young sister wore.
她穿着和她妹妹所穿的一样的裙子。

She joined MSF because all her life she has been eager to help people who might otherwise not get help.
3. what she did in Malawi
Her first assignment for MSF was to Malawi in 1997, where she worked with young children suffering from HIV/AIDS. She became very upset when she found that there were not enough medicines to cure the children and that so many died. Gradually she saw the situation improve.
4. what she did in the Sudan
She made the same commitment to the people of the Sudan when she worked there. But this time her problems were different. The climate and the basic conditions of the clinics made her life very challenging. But she could still laugh about some of her experiences. She admitted that “it’s amazing what you can do when you have no choice.”

Her experiences make her grateful for what she has. She is very delighted that she can help people in need. She values her past experiences.
6. her plans for the future
The future seems full and satisfying for Dr Murray. She will be returning to the Sudan to work for MSF for another six months. Then her plans are uncertain. She hopes that it will include returning to work in Africa though.
