Прочитайте текст и выполните задание после текста.

The dance starts in thirty minutes, but Wendy isn't ready yet. She is still in her bedroom. She is looking at her new dress hanging on the wall.

Her new dress is black with lovely roses on it. It is very elegant and Wendy looks beautiful in it. When Wendy wears it, it seems to her she is a film star.

Still, Wendy isn't sure if she wants to wear the black dress to the dance. That's because she didn't buy it. She made it herself. Wendy loves to design and make her own clothes. She wants to be a clothes designer when she grows up. But at the moment she is uncomfortable. She doesn't want to be the only girl at the dance wearing a homemade(сшитое вручную,самостоятельно) dress.

Wendy opens her wardrobe. She takes out a big box and looks into it. In it there is the dress her mother bought her for the dance. It is white. It is pretty, but not as elegant as the black dress. She hangs the white dress on the wall next to the black one and steps back. She looks at the both of the dresses and doesn't know what to do. After a while she decides that she likes the white dress, but she loves the black one.

“What will my classmates think if they find out that my dress is homemade?” she thinks. Wendy feels very nervous. Finally she takes the white dress and stands holding it in front of the mirror.

Wendy decides to risk . She puts the black dress on. She takes one more look at the mirror and went to the door.

Wendy arrives at the dance and her friend Susan meets her there. She is also wearing a dress. It is red with grey flowers on it.

“You look great,” Susan says to Wendy.

“Thanks,” Wendy says. “You do too!”
