（2019徐州）Mr Scott talked about colours all the time. "What a honey-yellow morning it is!" he said to his wife. His wife planted fruit and vegetables in their garden, but Mr Scott was more interested in the leafy plants, the bushes, and even the grass that grew in the garden. "So many kinds of green," he said to her after watering all the plants. "I counted at least twenty shades of green!"
"Well done, dear," Mrs Scott said. " Now would you please count twenty dollars and go to the supermarket for some ingredients（配料）?I want to make lunch! "
With a smile on his face, Mr Scott left at once. He enjoyed trips to the supermarket because of all the colourful cans and boxes in it. Fruit and vegetables, too, shone in their bright skins. There was never just one colour: carrots were orange, but also had bits of yellow and brown in them. Bananas were yellow and black; apples hid oranges and purples inside their reds. Mr Scott would walk through the supermarket and enjoy all the colours around him.
"I wish there was a store full of colours that I could spend all my time in, " he sighed.
He bought everything on his wife's list and came home. When he walked into the house, Mrs Scott noticed the sad look on his face. "What's wrong?" she asked him. "It looks life you had fun at the store. I can see that you picked out the best things."
"I did have fun in the store. So much that I wish I could have spent more time there. It's so full of colours! " Mr Scott said.
"I see, " Mrs Scott said. "Well, cheer up, because I'm going to cook a nice lunch for us!"
The next day Mr Scott was on his usual morning walk through the neighbourhood, saying hello to everyone, enjoying the colours of the trees and flowers. It was another day of colours!
"Good morning, Mr Brown," he called out to one of his neighbours. He liked Mr Brown very much, because, well, you guessed it: his name was a colour!
"Mr Scott! Just the person I wanted to see!" Mr Brown replied. "My wife and I are moving out of this town, and I need someone to take over my shop. You are the perfect person for the job because it's a paint shop! I need someone who knows its colours. Would you be interested?"
Mr Scott was mad with excitement. "I will take it over right away!"
Mr Brown was relieved when he left town, because he knew his paint shop was in good hands. Sure enough, Mr Scott kept the paint shop open for twenty more years and got to talk about colours all day, every day.
26. Why did Mr Scott come home from the supermarket sadly?
A. He hated shopping in the supermarket.
B. He didn't enjoy the colours in the supermarket.
C. He didn't have enough money to buy everything on his wife's list.
D. He liked the colours in the supermarket so much that he didn't want to leave.
27. Why did Mr Scott like Mr Brown very much?
A. They were neighbours. B. Mr Brown had a paint shop.
C. They shared the same hobby. D. Mr Brown's name was a colour.
28. What does the underlined word "relieved" mean?
A. 宽慰 B. 不舍 C. 犹豫 D. 烦恼
29. What's the best title for this passage?
A. A colourful paint shop B. A colour lover
C. A friendly neighbour D. A happy couple

A natural disaster is a major adverse (有害的) event resulting from natural processes of the Earth which includes floods, volcanic eruptions (火山喷发), earthquakes, tsunamis (海啸), and other geologic (地质) processes.
