Sometimes we suddenly feel like eating a certain food. Maybe you want a piece of chocolate to go with your coffee or chips when you are watching a movie. But some people want things that are not even food. They want to eat dirt or paper. Some people even want to eat glass. While you and I might be able to say no to chocolate or chips, the wish to eat things that are not food is really strong for some people. Even though they know the item could hurt them, they cannot help but eat it. This is called pica.

A person is said to have pica if they want and eat non-foods for over one month. Young children often put things in their mouths and might eat them. This is because at their age, they are learning about the world. There are some places in the world where eating non-foods is a tradition. For example, in some areas of Africa, women eat a kind of dirt. That would not be called pica because it is a tradition.

Pica can cause problems for health. People might have to see a doctor to have non-food objects taker out, or they may be poisoned. If the thing a person eats contains something bad, it can cause problems for the brain. Eating dirt can make people sick because there may be small bugs in the dirt. Those bugs can live in the body and eat the food the person eats. In that way, the person is not getting anything that is good for them from the food. People who have pica should get help from their doctors.

【推荐1】Have you ever looked at the sky and thought about darkness? Is it nothing? Or is there something in the dark? Cosmologists (宇宙学家) try to answer questions about things in space. They even study the darkness in space. They say the universe is about 5 percent “normal” matter—things we can see, like Earth and other planets, and the sun and other stars. But about 70 percent of the universe is something called dark energy.

Cosmologists say the other 25 percent of the universe is dark matter. Dark matter has some weight. It’s heavy so we know it’s there. But we can’t see it, so it is very hard to study something that you can’t see!

One possible kind of dark matter is a brown dwarf (褐矮星). A brown dwarf is too big to be a planet and too small to be a star. Brown dwarfs are colder than stars, and they don’t give off light that people can see. Cosmologists found them by using a telescope that finds heat. They found the first brown dwarf in 1995.

Cosmologists know a lot about one kind of dark matter—black holes. In 1783, an English astronomer, John Michell, guessed that there were black holes. But cosmologists didn’t find any black holes until 188 years later. Since then, they’ve found many black holes in space.

It’s very dark with much gravity (引力) in a black hole. There is so much gravity in a black hole that nothing can get out, not even light. This is why we can’t see them. Cosmologists find black holes by looking at things around them.

For example, stars and gases near a black hole move very fast.

Things in space can fall into a black hole, and when they do, they can never get out. But don’t worry—Earth will never fall into a black hole because there is not one close enough.

1. When did cosmologists first find black holes?

A．In 1783.

B．In 1971.

C．In 1995.

D．In 1595.

2. What can we know about brown dwarfs?

A．They are as big as planets or stars.	B．They give off light that people can sec.
C．The first one was found by using a telescope.	D．They are much hotter than stars and planets.

3. What would be the best title for the passage?

A．Black Holes in Space.	B．Dark Energy in Space.
C．Normal Matter in the Universe.	D．Dark Matter in the Universe.

4. What can we infer from the passage?

A．We have known nothing about dark matter so far.

B．Earth could fall into a black hole in several centuries.

C．The earth is too far away from a black hole to fall into it.

D．The biggest black hole is as big as ten billion of our sun.
