I don’t get along well with my mother. It feels like every time my mother and I start to have a(n)
1
, it turns into an argument. We talk about something as
2
as dinner plans or travel plans. And
3
, my mother will make a remark pushing the chat into World War III. She’ll talk about my lack of a(n)
4
future because I don’t plant to be a doctor. And much to her
5
, I don’t want to do any job related to the science field either. In fact, when I was pushed to say that I
6
to major in English and communications, she nearly had a heart attack.
“Why can’t you be like my co-worker’s son〞 She’ll
7
all the time. Her co-worker’s son
8
a four-year scholarship in college. Now he is
9
70,000 dollars a year as an engineer. I don’t know what to
10
except that I simply can’t be like Mr Perfect as I’ve called the
unnamed co-worker’s son. I can’t be like him. I’m the type of person who loves to
11
in the community, write until the sun goes down, and
12
, wants to achieve a career because I love it . I don’t want to do a job just for fame or
13
. I understand why my mother is
14
my future majors. I’ve seen my mother
15
to raise me on her little salary〔工资〕and long hours. She
16
the house around 6:30 am and usually comes home around 5 or even 6 pm.
17
, I want her to know that by becoming a doctor, it doesn’t mean I’ll
18
be successful. I’d rather follow my
19
and create my own future. Dear Ann, could you give me some
20
I do want to solve this problem. Sincerely

D．time VII 阅读理解 We are all called upon to make a speech at some point in life, but most of us don’t do a very good job. This article gives some suggestions on how to give an effective speech.

that again. 〞
Cheer up! It doesn’t have to be that bad. Here are some simple steps to take the pain out of speech making. Ask yourself the purpose of your speech. What is the occasion Why are you speaking Then, gather as many facts as you can on your subject. Spend plenty of time doing your research.
