Imagine you are at a cafe in the United States. The server walks toward you and asks the following question:

Did you want cream for your coffee? Why do some Americans use the past tense when they are talking about the

present?

Simple Past Tense

The simple past tense is used for actions or situations that happened in the past. These actions or situations

are finished. For example, you might hear a person say, "Did you have a good weekend?"The traditional use of the

simple past tense is this: to note complete actions or situations in the past.

Simple Past Tense with "want" and "need"

However, there are exceptions. For example, in conversation, Americans often use the simple past tense of

the verbs want or need even though they are asking a question about the present. Let’ s go back to the American

cafe. You might hear a conversation like this:

Server: Did you want cream for your coffee?

Customer: No thanks!

Server: Did you need more water?

Customer: Yes, please!

In the conversation, the server uses the simple past tense when asking questions. So, why did the server use

the simple past tense instead of the present tense?

Culture and Grammar

In American culture, it is often considered polite to speak indirect. One was some Americans speak indirectly

is by using a past tense verb when asking about a present desire. Americans do this by using the construction did +

want and did + need.

However, speakers do not answer such questions in the simple past tense. The answer usually comes in the verb forms that you would expect—a simple present, present progressive or future tense verb, for example.

1. What is the main use of the simple past tense?

A. To express politeness to people.

B. To communicate with customers.

C. To state what happened in the past.

D. To describe actions and situation clearly.

2. What does a server say when serving a customer in America?

A. Did you buy any food? B. Do you want some milk?

C. Did you need more coffee? D. Do you want to pay your bill?

3. Which of the following is a correct answer to the question "Did you want tea?" according to the text?

A. Yes, I did. B. No, I don’ t .

C. You are welcome. D. I would have some.

B

At times my mom has been uncomfortable seeing these qualities in me. For example, when I was 12, I went

to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about

it. She kept telling me how things were different in Puerto Rico, to always put on sunscreen, not to wander away

from my grandmother, and other warnings. She helped me pack and did not leave the airport until she saw my

plane take off.

But despite her worries, she let me go on my own. As I moved into my teens, she continued to give me space

to grow and learn, even when it might have been difficult for her. When I reached my senior year, I decided to

move away for college. Once again I found that I differed from my peers. While many of them wanted to stay

close to home, I couldn’ t wait to be out in the world on my own. I had been looking forward to this chance for

longer than I could remember. And once again, while my mom may not have been happy at the thought of me

going away, she was supportive and excited for me. Sure, there were times when she’ d nag (不断地唠叨)me

about certain choices I made, but for the most part she did not stand in my way.

One big thing I realized during my senior year was that she actually believes in me and trusts me. That means

a lot. Most of my life, and especially when I was little, the main person I tried to impress was my mother. I knew

she expected nothing but the best from me. Sometimes it was hard to live up to her standards; getting a single B on

my report card would make me feel bad because I knew she wanted me to have all A’ s.

I know that her high standards have helped me stay focused on what’ s important, like education, and made

me who I am. I am thankful for her support and involvement in my life. Most of all I respect her; she is the
