States of Matter  Matter is made of atoms and molecules.  Water, for example, is the H2O molecule. This means that a molecule of water has 3 atoms. A water molecule has 2 hydrogen atoms and one oxygen atom.  Substances like sugar have many atoms in their molecules. A molecule of sugar has many atoms, including carbon, hydrogen and oxygen. Matter is made of molecules, such as H2O, which is the water molecule.  Matter can be in one of three states: solid, liquid or gas. Water and ice are the same substance, but they are in different states.  These states depend on the temperature of the molecules. When we heat a substance, the molecules move faster and try to take up more space. When we cool a substance, the molecules move more slowly. When we cool a substance to its freezing point, it becomes a solid. In a solid, the molecules move very little.  Their positions are almost fixed. To be fixed means that their positions don’t change. If we heat the molecules, they move faster and away from each other.  The solid begins to melt, like ice cream on a hot day. At a certain temperature, the solid begins to change into a liquid. The temperature at which a solid changes into a liquid depends on the substances. For water, the solid begins to change into a liquid when its temperature rises to above 0 degrees Celsius.  For some substances, such as steel, the temperature at which it becomes a liquid is much higher. Steel often melts at around 1370 degrees Celsius. If we continue to heat a liquid, the molecules move even faster.  At a certain temperature, the liquid begins to change into a gas. For water, the liquid begins to change into a gas at 100 degrees Celsius.  That is the boiling point of water. Inside a star, such as our Sun, the temperature is very high.  Everything inside the Sun is a gas. According to scientists, there are over 65 elements inside the Sun.  These include oxygen and iron. Over 90 percent of the Sun is hydrogen gas. Tests Results Yesterday there was an important science test. Lisas, Tom and 20 other classmates took the test. The test was about the states of matter and how they are different. There were 25 questions on the test, and they had 45 minutes to take it. Here are some of the test results. Two students got perfect scores. The lowest score was 68 out of a hundred. The average score was . Eleven students scored higher than average. Eleven students had below average scores.

You were supposed to be here 30 minutes ago. M: I got on the wrong subway by mistake. W: Why didn't you call? I was really worried. M: I don't have my phone. I left it in the office because I was in such a hurry to get here. W: OK, well, you're here now. We don't have much time. M: Yes, we'll have to hurry. The meeting starts in 15 minutes, right? W: Yes, it's supposed to, if everyone gets here on time. W: Did you read my presentation? M: Yes, I do. It's good, but it's a bit too long. I'm afraid there won't be enough time for questions.

Tom: What was it? Lisa: I said 90% of the sun is Helium instead of Hydrogen. Tom: Wow. That was a stupid mistake. Tom: What was the average score for the class, do you know? Lisa: The average score was and the lowest was 68. Tom: Do you know who got the lowest test score? Lisa: No, I don't. I don't know who got the lowest score. Tom: It's probably a secret.

最重要的区别应该是内容不同吧。毕竟，如果内容一样的话，就没有必要摆上上中下旬三本了，直接摆一本就可以了。
