摘要： What do you think of Iris? A. Brave. B. Kind. C. Honest. D. Too careful. B On a rainy day, you will see many streams of muddywater running down the slopesof a hill. The water is muddy because it washes away soil from the hill slopes. Sometimes soil is blown away by strong winds. When the soil is carried away by water or wind, we say that the land is eroded. This is known as soil erosion. Plants cannot grow on eroded land. There is not enough soil on eroded land to give them the things they need. Plants need water and salts from the soil. We can do a number of things to stop soil erosion. This is called soil conservation. One way of soil conservation on flat, open ground is to grow small plants such as grasses. Their roots hold the soil tightly together. Another way is to plant trees around an open field. Thus soil erosion by strong winds cannot take place. Rows of trees act as a very big wall. Soil erosion on slopes can be stopped by cutting “steps called terraces. Water carrying soil cannot run straight down the slope now. It has to run down the terraces. This slows down the flow of the water. Most of the soil in the water is left behind on the terraces. There are some other ways of soil conservation.

Iris is very forgetful and so she worries a lot. She worries a lot and so she becomes even more forgetful.
She also talks to herself a lot.
One day, she has her hat and coat on and is just about to open the front door. She stops for a moment.
"Is the electric cooker off?"
Iris never forgets to turn the cooker off but she goes back to the kitchen to make sure. Yes, the cooker
is off.
"But is the TV off in the sitting room?"
She goes to the sitting room and feels a knob (旋钮) on the TV set.
"Yes, I don't usually forget that. Oh dear! It's getting a bit late. I don't want to miss that train."
So she goes back to the front door and opens it. She is going through the doorway when she stops
suddenly.
"My key! It's somewhere in my handbag, I think. No, it's not in my purse; not in the front pocket. Ah,
I know! Yes, it's in my coat pocket. Thank goodness! I must run all the way."
Halfway down the garden path she looks at the sky, which is covered with grey clouds.
"I know it's going to rain. And that bedroom window is wide open. I must close it. I suppose I can
catch the next train."
She opens the door again, putting the key back in her handbag. She throws her handbag on the hall
table, rushes upstairs and closes the window.
Then she runs downstairs and straight out of the house, closing the door behind her noisily.
But she doesn't catch either the first or the second train.
And it doesn't rain all day.
Poor Iris!
