When I was about twelve, I suddenly developed a great passion for writing poetry. I gave up all my other __ 21     , such as playing computer games,   22      foreign coins and stamps, and spent all my spare time reading poetry and writing it. This habit of writing poetry on every possible    23    soon got me into trouble at school. If a lesson did not interest me, I would take out my note-book and start writing poems in class. Of course ,I did this very    24   , but it was not long before I got    25    . One day while l was busy writing a poem during a geogrophy lesson, I looked up to find the teacher standing over me, staring with anger because I was not    26   attention. He tore the poem up, with a    27     not to waste time in his lesson. All the same I was convinced that I had written a good poem, so that evening I wrote it out again from memory. Not long after, I read about a poetry contest and I decided to send in my poem. Weeks later, long after I had given up hope, I got a letter informing me I had won first    28   . Everyone at school was very impresed-except the geography teacher, who     29     me more carefully than ever. He was quite    30    that I was not going to write poetry in his lesson!

              Have you ever wondered?

1. Why do airplanes take longer to fly west than east?

It can take five hours to go west-east from New York(NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet(喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when the air moving with the wind than in the opposite direction.

2. What would happen if the gravity(重力) on Earth was suddenly turned off?

Supposing we could magically turn off gravity. Would buildings and other structures float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed moving at over a thousand miles per hour. If you turn something round your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. “Switching off ” gravity would be like letting go of the string. Things not attacked to the Earth would fly off in a straight line . People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things would fly off into space.

What information can we get from the first passage?

A. It is the jet stream that affects how fast airplanes fly.

B. Planes go slower when they are moving with the wind.

C. It takes more time to fly from NY to London than from London to NY.

It can be inferred that without gravity          .

A. buildings and other structures would float away

B. trees and buildings would not so easily fly off

C. something around your head would not float away

D. everything outside buildings would fly off into space

Where can we most probably read this text?
