Matter is made of atoms and molecules.
Matter马特; 物质; 事件
made of把…培养成
atoms微粒; 原子( atom的名词复数 ); 原子能; 微量
molecules分子( molecule的名词复数 )
Water,for example is the H2O molecule.
This means that a molecule of water has three atoms.
A water molecule has two hydrogen atoms and one oxygen atom.
hydrogen<化>氢
atoms微粒; 原子( atom的名词复数 ); 原子能; 微量
oxygen氧，氧气
Substances like sugar have many atoms in their molecules.
Substances物质( substance的名词复数 ); 实质; 物体; 1)。 本质
A molecule of sugar has many atoms,including carbon,hydrogen and oxygen.
carbon碳; 复写纸; 碳精棒[片，粉]，碳精电极; 复写的副本; 碳的; 碳处理的
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.
be in到达，执政; 在家; 搞
one of其中之一
solid固体的; 实心的; 结实的，可靠的; 可信赖的; 固体; 立体图形; 立方体
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.
heat热，热度，高温; 热烈，激烈; 发烧，发热; 发情; 使温暖，使热; 激发…的感情，使兴奋
try to设法
take up占用; 开始从事; 接受
space空间，太空; 空白，间隔; 空隙; 片刻; 把…分隔开，留间隔于…之间; 以一定间
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.
positions阵地; 地位; 职位( position的名词复数 ); 状态
fixed固定的，不变的; 不易挥发的; 处境…的，常作复合词; 通过作弊预先安排好结果的; 固
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.
melt熔化，溶解; 逐渐融合; 逐渐消失; 感动，软化，感情上变得温和; 使混合在一
To change a solid into a liquid,add heat.
At a certain temperature ,a solid begins to change into a liquid.
The temperature at which a solid changes into a liquid depends on the substance.
For water,the solid begins to change into a liquid when its temperature rises to above zero degrees Celsius.
For some substances,such as steel,the temperature at which it becomes a liquid is much higher.
steel钢，钢铁; 钢制品; 兵器; 钢铁工业; 包上或镀上钢; 使坚定; 钢制的; 钢铁业
Steel often melts at around One thousand three hundred and seventy degrees Celsius.
If we continue to heat a liquid,the molecules move even faster.
continue持续; 逗留; 维持原状; 延期; 使延伸; 使持续; 继续说
At a certain temperature,the liquid begins to change into a gas.
For water,the liquid begins to change into a gas at a hundred 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 Sixtyfive elements inside the Sun.
According to根据，按照; 据…所说; 如; 比照
elements成分; 原理，基础; 要素( element的名词复数 ); 元素; 基础
These include oxygen and iron.
Over Nighty percent of the Sun is hydrogen gas.
