Ⅱ.阅读理解
I've always felt a need to be prepared for whatever the situation I've found myself in.
My mother once took me to a store when I was seven years old. She and I got to the checkout counter, and she realized she had forgotten a couple of things on her shopping list. She left me with the cart and ran off to get what she nee ded. “I'll be right back，” she said. She was gone just a few minutes, but in that time, I had loaded all the things on the belt and everything was rung up. I was left staring at the cashier, who was staring at me. “Do you have money for me, son？” she said. “I'll need to be paid.” I didn't realize she was just trying to amuse herself. So I stood there, ashamed and embarrassed. By the time my mom returned, I was angry. “You left me here with no money! This lady asked me for the money, and I had nothing to give her！”
Now that I'm an adult, you'll never catch me with less than $200 in my wallet.
I want to be prepared in case I need it. I've always admired people who are well­prepared. In college, I had a classmate named Norman. One day he was giving a presentation on an overhead projector (投影仪) and in the middle of his talk, the light bulb on the projector blew out. We would have to wait ten minutes until someone found a new projector. “It's OK，” he announced. “There's nothing to worry about.” We watched him walk over to his bag and pull something out. He had brought along a spare bulb for the overhead projector. Who could even think of that?
I often told my students, “When you go into the wilderness, the only thing you can depend on is what you take with you.” And esse ntially, the wilderness is anywhere but your home or office. So take money. Pack a light bulb. Be prepared.
这是一篇夹叙夹议文，作者用自己童年时和大学时的经历说明了一个道理：打有备之战，方能取胜。

1．Why did the cashier ask the author to pay for the purchases?
A．Because he was shopping by himself.
B．Because his mother asked her to do so.
C．Because she was playing a joke on him.
D．Because his mother was away for something else.
答案：C
解析：细节理解题。

依据第二段中的“I didn't realize she was just trying to amuse herself”可知，这位收银员在和作者开玩笑，故选C项。

2．Why was the author angry with his mother?
A．His mother left him alone.
B．He lost face in front of the cashier.
C．His mother forgot to buy something.
D．He had just quarreled with the cashier.
答案：B
解析：推理判断题。

依据第二段中的“So I stood there, ashamed and embarrassed”可知，当作者意识到自己没有钱去结账的时候，他感到尴尬和难为情。

由此可推知，下文他对母亲生气是因为他感到很丢面子。

故选B。

3．Why did Norman bring a spare bulb with him?
A．He was always well­prepare d.
B．His presentation was about bulbs.
C．He knew the classroom equipment was of poor quality.
D．He predicted the bulb on the projector would blow out.
答案：A
解析：细节理解题。

根据第三段中的“I've always admired people who are well­prepared”可知，Norman是一个有准备的人。

4．What do the two stories in the passage tell us?
A．Accidents happen almost every day.
B．Money is the key that opens all doors.
C．In fair weather prepare for the foul.
D．Chances favor those who are well­prepared.
答案：C
解析：推理判断题。

文中的两个故事都讲述了应提前做好准备、未雨绸缪的道理，因此选C。

“In fair weather prepare for the foul”意为“未雨绸缪”。

Ⅲ.读后续写
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

续写的词数应为150左右。

We never know the difference we might make if we take the time to encourage someone.
I gave up the idea of being a writer the summer before I started college. I'd been writing since I was five years old. My little friends wanted toys that year.
I wanted paper. Childhood passed and a box of short stories gave way to my middle
school days. I wrote for a magazine and by the time I was in eighth grade, half the annual publication was written by me.
Sometimes I'd dream with my parents about being a novelist, writing books that everyone might read. My dad was always sure it would happen. He would read one of my poems or stories and his tears would well up. “That's beauti ful, honey，” he'd tell me. “One day people from all over the world will know what a gift you have.” Those words encouraged me through high school to keep believing that writing was my calling.
But somewhere along the way, during the months of my senior year, I became disappointed. The crazy injustice in this world—bad guys getting back out on the street and doing harm again and again—changed my mind.
“I'm going to be a lawyer，” I told my parents.
My dad's face fell, but he kept his smile. “Whatever you do,you'll be brilliant at it，” he said.
One of my first classes at college was journalism. A few weeks into the term, the professor, Bob Scheibel, assigned us a story about an apartment fire. He gave us the facts and we had a few days to write a news story.
I remember turning in that first paper, sure that I had the facts right. I didn't expect much feedback(反馈). But a few days later, Bob Scheibel asked me to talk to him after class. Questions raced through my mind. What had I done wrong? Had I got the facts mixed up? Did I miss something critical in the details? By the time the class was over, I found myself in front of the professor. His eyes met mine with great seriousness.
答案
Paragraph 1：
“You will never ever stop writing，” he said. “You are a very, very g ood writer. Don't change your mind.” I left him that day a different person. My back felt a little straighter; my steps came a little quicker. I was a writer. Professor Bob Scheibel had told me so. The next day I did what he said.
Paragraph 2：
Two years ago, after my first bestseller, I found Bob Scheibel. I called him and he still remembered me. He congratulated me on my writing success, and I told him my memory of that special day and that I wouldn't have been a writer if he hadn't said those words. I knew Professor Scheibel was touched and after a long moment he thanked me. That's the thing with little words. The words my parents said to me when I was growing up and the words Bob Scheibel said to me that day after his journalism class made a difference to me.。
