【題目】下列比例尺中,圖幅相同時,表示內容最詳細的是(  )
A.1:1600000
B.200萬分之一
C.
D.

【答案】A
【解析】比例尺是表示圖上距離比實地距離縮小的程度.在圖幅相同的條件下,比例尺越大,表示的范圍越小,內容越詳細;比例尺越小,表示的范圍越大,內容越簡略.
比例尺大小比較時,比例尺不是數字式的應先化成數字式再比較大小;四個比例尺為:A是1/1600000,B是1/2000000,C是1/4000000,D是1/5000000,數字式比例尺大小的比較,分子為1,分母越大比例尺越小,反之則越大;比較選項中的比例尺得知,1/1600000比例尺最大;在圖幅相同的條件下,比例尺越大,表示的范圍越小,內容越詳細,故選項A符合題意.故選:A.

【題目】

Coloring is an activity that children worldwide have long enjoyed. With a picture already made for them, kids simply chose a crayon,pencil or marker of their favorite color and fill it in. Today, it also becomes more and more popular among teenagers and even adults, who are enjoying relaxing hours of coloring. In December, five of the top ten best-selling books in the United States were coloring books.

They are fun,but are coloring books good for you?

The good feedback(反饋)from customers is encouraging. Trina Lucida, a popular artist creating coloring books, says that many of her customers are buying the coloring books for others who are sick or going through a hard time. She adds that the "big idea" behind her latest book is to encourage people to do something creative.

Lucida is right,according to Allan Rohan,a psychology(心理學)professor. "Many customers think of coloring books as a new creative stage," he said in an interview,"but what's more important is that people spend time coloring in order to reduce stress after a long day." Research shows that coloring can reduce stress by guiding people to focus on(專注)one simple task. When a person is filling in a flower with a light purple color,he focuses on the flower and forgets about all his troubles in life.

Experts add that coloring may relieve a certain kind of pain. Doing the coloring helps people relax their mind and calm down. Also,coloring helps people's brain in a healthy way. The shape of the drawing makes one side of the brain active, while the color of the drawing improves the other. Coloring can bring out your imagination and take you back to your childhood. Interesting,isn't it?

"It's very relaxing," said Susan Jackson,a big fan of Lucida's coloring books. "Coloring frees my mind. And it's not just to try to fill blank(空白的)pages. The pictures make me happy and there is just something about them. So I'm saving the pictures I like best to the very end."

1Trina Lucida wants her coloring books to .

A. encourage people to be creative B. be one of the best-sellers

C. let people enjoy relaxing hours D. help develop their friendship

2Why can coloring reduce stress?

A. Because it brings out imagination.

B. Because it shows the beauty of nature.

C. Because it helps people to be more focused

D. Because it can take people back to childhood.

3What does the underlined word "relieve"mean?

A. reduce B. seuarate C. drive D. balance
