can survive.

A valley is a low relatively flat area between hills or mountains, often
with a river running through it. Some valleys are formed by flowing

Vocabulary : Science
A force is a push or a pull on an object.
A force changes the motion of a moving object.
A force can be strong or weak and it always has a direction.
The Earth is a planet that goes around the sun in a circular orbit.
The speed of its motion doesn’t change, but the direction of its motion does.
The Earth has a layer of gas above its surface which helps to support life.
Atoms are the building blocks of matter.
At the center of an atom is its nucleus which has a positive electric charge.
Outside the nucleus are electrons which have a negative charge.
Asteroids and comets are objects that obey our sun, but are smaller than
9

planets.
Asteroids that pass close to the Earth are called near-earth objects.
The layer of gases just above the Earth’s surface is our atmosphere.
The atmosphere is made of gases such as oxygen and nitrogen.
Without an atmosphere there would be no life on Earth.
If they collide with Earth they could cause an extinction event.
A force can increase or decrease the speed of an object, and it can change
the direction of motion.
The electric force between the nucleus and the electrons holds the atom
together.

Vocabulary : Geometry
The two lines on the left intersect each other at a right angle which is 90
degrees.
The two lines on the right are parallel which means they never cross.
The adjacent sides of a rectangle are perpendicular which means they
meet a 90-degree angle.
The opposite sides of a rectangle are equal and parallel which means they
never cross.
The area of a rectangle is the length times the width.
A circle is a two dimensional figure with a radius and a circumference
which is the distance around the circle.
The area of a circle is Pi R squared, where R is the radius and Pi is the
ratio of the circle circumference to its diameter.
10

A sphere is a three dimensional figure with a radius and a volume which is
four thirds Pi R cubed. All points on the surface of a sphere are equidistant
from its center.
A right triangle is a two dimensional figure with three side, two of which
are perpendicular.
To find its area, multiply the length of the two perpendicular sides a and b
and divide by 2, A equals 1 half ab.
A rectangle is a 2 dimensional figure with 4 sides.

Dialogue ： Dinner Conversation
M: Have you finished eating yet?
W: No, I haven’t. Why are you in such a hurry?
M: I’m sorry, but you are such a slow eater.
W: A slow eater? Well, I try to enjoy my food. You just eat and swallow.
