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 (大氣現(xiàn)象) known as the jet stream (氣流). The jet stream is a very high altitude (=" above" sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite.
2.      What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures（建筑物）float away? What happened would depend on (依靠) how strongly the things were attached (吸附) to the earth. The earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around 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. ‘Turning off’ gravity would be like letting go of the string. Things not attached 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 (=" top" surface of a room). Most things outside would fly off into space.
小題1: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.
D．The jet stream always blows from the east to the west across the Atlantic.
小題2:The underlined word “shoot” in the 2nd paragraph means “_________”.
A．send for B．move quicklyC．come out D．grow quickly
小題3:It can be known 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
小題4:Where can we read this passage?
A．In a research paper. B．In a short story.
C．In a travel magazine.D．In a student’s book

Now, there is a new-type school in New York, which has no everyday lessons, no class teachers and even no school buildings. It is called “City-as-School”. The name just means the city itself is the place where students learn their lessons. They are from the age of 15 to 18. The students choose areas of work which interest them. Then they help to do that work. One girl spends her week in a government office helping the public with problems like housing. Then she goes to help in a theatre for a day and she spends a week for first-year courses at college.
Well, students have to pass Maths and science exams before they enter the “school”. These subjects are not easy to provide in“City-as-School”. Teachers watch the progress of the students. The success rate (比率) is high. 80% of the students go to college after the “City-as-School”.
The students like the duty of their work. They have the sense of purpose. They know a lot about different kinds of work in the city. One of the students, Lizette Martinez, writes “ I want to say that I do not know where I would be right now if I had never become part of City-as-School. Leaving my regular high school and going to City-as-School was the best decision I have ever made. The way the school works to get you to go out there and learn different fields instead of sitting in a classroom is wonderful. For all those who are in between school and dropping out, go to CAS and it will change your life forever.”

In every school there is “top” crowd that sets the pace, while the others follow their lead. For example, if the crowd decides that it is smart to wear bright red sweaters, then very soon everybody is wearing bright red sweaters.
There is nothing wrong with that, except the fact that for some people bright red sweater is really unsuitable.
The situation can even become dangerous, if the top crowd decides that it is smart to drink and to drive cars at seventy miles an hour. Then the people who follow the lead are endangering their lives. They are like the sheep being led to the slaughter(屠殺).
Now it’s possible that you have come across situations like these more than once in your life. In fact you probably did something you knew to be wrong one time or another. You may have excused yourself by saying, “ Gee, the crowd does it.” Well, let the crowd do it, but don’t do it yourself. Learn to say “No”.
Develop your own standards(標(biāo)準(zhǔn))and your own judgment. If you know the crowd is planning something you disagree to, you’d better take the courage to bow out in a polite way. You’ll have the satisfaction of standing on your own two feet.

Scientists (科學(xué)家) think that many animals cannot see colours. The world is black and white to them. Scientists want to find out if (是否) dogs can see colours.
