THE MEANING OF DREAMS
Did you have any interesting dreams last night?
Our dreams come from a part of the brain that contains our thoughts and memories. A person can have up to six dreams a night, and each dream usually lasts from 10 to 40 minutes. Everyone dreams, but not everyone remembers their dreams. Most people dream in color, usually with sound. And we usually dream about ourselves and the people we know.
Why Do We Dream?
Alan Siegel is a scientist who studies dreams. "Dreams help us get in touch with our deeper feelings,” he says. "They can tell us a lot about ourselves, and can help us figure out problems.” Another scientist, Robert Stickgold, thinks dreams come from our memories. He believes we dream to remember, because memories are useful to the brain. Stickgold says the purpose of dreaming through these memories is to help us learn from the past.
Here are a few types of dreams and what people think they mean.
Dream 1: You Meet Someone While in Your Pajamas
Sometimes people dream that they meet someone they know while wearing their underwear (or nothing at all!). This dream may be the result of an embarrassing event in your life. Some people think we dream about embarrassing situations if our brains are trying to deal with an event in our own lives.
Dream 2: You're Flying
If you dream about flying, you are probably quite happy. This is a good period in your life. You may feel that other people see you as a leader.
Dream 3: You Didn't Study for a Test
This probably means you are worried about an important event coming in your life. If you're not prepared for the event, your dream may be telling you, "It's time to get to work!"According to the passage, which of these sentences is true?
A.If you dream you’re wearing no clothes, something embarrassing probably happened to you.
B.If you dream you’re flying, this is probably a difficult time in your life.
C.If you dream you didn’t study for a test, you’re probably not getting enough sleep at night.
D.If you dream you’re working, an important event will probably come in your life.

HOW WILL WE LIVE IN 2035?
Welcome to life in the future!
You get up in the morning and look into the mirror. You've just had an anti-aging treatment, so your face looks youthful. In 2035, many people your age could live to be 150, so at 60, you're not old at all.
Science has also found amazing ways to keep people healthy. There are nanotechnology treatments for many illnesses, including cancer. And if any part of your body is not healthy, you can "grow'' a new one in a laboratory.
As you get dressed, you say to your shirt, "Turn red." It becomes red. In 2035, “smart clothes" contain nanoparticles that carry electricity. So you can program clothes to change colors or patterns.
On the way to the kitchen, you want to call a friend. Your cell phone is by the window because the material it's made of takes in energy from the sun. But you don't need to pick up the phone. You can just touch your jacket sleeve to make the call.
These are just some examples of nanotechnology all around you. "Your whole body and surroundings [will] become part of the same network," says scientist Ampy Buchholz.
It's breakfast time. You reach for the milk, but a voice says, "Don't drink that!" Your fridge is reading a computer chip on the milk. Every item from the grocery has a chip. Your fridge knows the milk is old, and tells the store you need new milk.
Finally, it’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go, and soon you will be there.
So, will all these predictions come true? Perhaps the future is much closer than we think.
Which of the following predictions is NOT mentioned in the passage?
A.You will be able to grow new body parts.
B.Clothes will be able to change their patterns.
C.There will be no more cell phones.
D.Your fridge can tell the store you need new milk.

THE ROBOTS ARE COMING!
The year is 2045. A goal is scored at the soccer World Cup. Not by a human player, but by a robot. A robot? Is that possible? Many scientists believe it is. In fact, there are already robots that can play soccer. Of course, today's robots don't just play sports. Today's scientists are working on robots with various skills. For example, it is very possible that robots will soon help take care of children or the elderly, or do dangerous jobs such as fighting fires.
When people started making robots, they were made to do just simple things, mainly in factories. Since then, however, robots have changed a lot. Early robots were operated by humans. Today's robots function on their own. Some can only move around a little, like robot vacuum cleaners, but others, such as Honda's ASIMO, can do much more. He can run, climb stairs, dance, and yes, even play soccer.
Then there are robots designed to be like humans. These robots have faces and can show emotions. Such robots can learn new things, and show us how they "feel.'' Actroid-DER—a social robot—looks so human, she sometimes makes people feel uncomfortable.
Animal-bots
Scientists aren't just building humanlike robots. They are also making robots that look and act like animals.
At NASA, scientists are making a robot snake. They think it's a good alternative to vehicles with wheels. These snake-bots can enter holes and move over rough ground. They might one day help scientists look for signs of life on Mars. Other animal robots include the frog-bot, which can jump over objects, and the sticky-bot, which can walk up walls. There's even a robot called Water Runner that can walk on water.
But can a robot soccer team ever operate all on their own, or play as well as a human team? Many robot scientists definitely think so. Among the robots of today are Honda's ASIMO (top left), the NASA snake-bot (bottom left), and Actroid-DER—the social robot (right). Anything is possible. One day, they may even be world champions!
Which of the following robots would best be able to move over a large rock in its path?
A.A frog-bot
B.Actroid-DER
C.Water Runner
D.ASIMO

SEA MONSTERS
Monsters of the Deep
Sea monsters are not just imaginary creatures. Millions of years ago, real monsters did actually live on Earth.
Today, scientists use fossils to help them figure out what these monsters were like. The fossils can help us understand some of the animals' unusual characteristics. After studying the fossils, the scientists can make very detailed pictures of these animals. So now, we can all see what they looked like.
Eyes in the Dark
Temnodontosaurus was definitely an unusual animal. Its name means "cutting-tooth lizard," and with good reason—it had very big teeth. It also had some of the largest eyes in nature. They were over 25 centimeters (10 inches) across! With such big eyes, Temnodontosaurus could easily find its food in the dark water.
Terror of the Deep
Kronosaurus—the "Kronos lizard"—lived in the seas that covered Australia. But it probably used its fins to climb out of the water and lay its eggs on land. Its head was two meters (seven feet) long. Its teeth were as big as bananas! The main function of strong jaws and teeth like these was to catch smaller animals. In fact, Kronosaurus was one of the most dangerous predators of all time.
The Stalker
Known as the "lord of the seas," Thalassomedon was a large sea monster with a very long neck. It also had a special means of catching fish: It carried stones in its stomach! These helped keep the largest part of its body and tail down in the dark water. Meanwhile, its long neck slowly rose up toward the fish. The fish didn't have a chance to get away from Thalassomedon. They didn't see the sea monster until it was too late!
What is unusual about Thalassomedon?
A.It laid its eggs on land.
B.It had very large eyes.
C.It had a very long neck.
D.Its head was very long.
