Reading A long extract from a novel
1 The main character in The Milhon the Floss is a girl called Maggie. Read the first
part of the text and answer the questions.
i What is the relationship between Maggie and Tom?
2 Who is Mrs Tulliver?
3 What was Maggie's 'big idea'?
"Well, how are you? I hope you're good children, are you?" said Aunt Clegg, "Put your hair
behind your ears, Maggie, and keep your dress on your shoulder
"I think the girl has too much hair; Aunt Pullet said. "It should be thinner and cut shorter. It
isn't good for her health
5 "Maggie" said Mrs Tulliver, "go and brush your hair
A big idea was taking shape in Maggie's mind. "Tom, come out with me; she whispered
"There's something I want to do before dinner"
Tom followed Maggie upstairs into their mother's room She opened a drawer and took out
a large pair of scissors.
10 "What are they for?" said Tom.
Maggie answered by taking the front part of her hair and cutting it straight across the
middle of her forehead
"Oh, Maggie, you'll be in trouble!" exclaimed Tom.

15 would look so weird.
"Here, Tom, cut it behind for me" said Maggie, excited by her own bravery.
"You'll be in trouble, you know' said Tom, as he took the scissors.
"Never mind, hurry!" said Maggie, giving a little stamp with her foot. Her cheeks were red,
One delicious snip, and then another and another
. The hair fell heavily on the floor, and
20 Maggie stood there, badly cropped but with a new sense of freedom
