呼……今天总算追上进度了。
默写晚点再来，先上今天的句子：
24. Most substances contract when they freeze, so the density of a substance’s solid is higher than the density of its liquid.
大多数物质遇冷收缩，所以他们的密度在固态时高于液态。
原句的so后面还有个that，
但物质收缩是“导致”固态密度高于液态，这个事情应该是客观事实，并不是“通过收缩去增加密度”的主观目的，因此删去that。
句式上没有特别复杂的，一个前因一个后果。
substances contract - when they freeze
so density SLID higher than LIQUID
没了。
分组就是：
Most substances contract
when they freeze
so
the density of a substance's solid
is higher than
the density of its liquid.
总觉得后面一般不会这么表达来着。不过问题也不大。
词汇：
#substance 物质；同时也是“实质、核心”的意思，是一个非常“结实”的词。短语in substance 实质上，大体上，比较好用。
#contract 收缩/缩小；名词是我们熟悉的“合同”，动词也有“约束”的意思。溯源它的词义有种“拉近距离合在一起”
#freeze 冷冻，过去式froze，过去分词/形容词 frozen，寒冷的，冰冻的。
#density 密度；物理学词汇。同时也可以是“浓度”的意思，也可以用作“人口密度 population density”以及信息密度、交通密度……等等，总之就是指单位空间内某物/物质的数量多寡的意思。
#solid 固体；固态；坚实的；可靠的；连续不间断的……solid基本上就是表示某对象紧密度极高的意思。
#liquid 液体；流动的；易变化的，基本上说的就是某物极具变化性，可能引申为不固定的，模糊的意思。
对于固液气这个组合，还有个gas或者gaseous，一般用gas就可以了。
全句默写：
Most substances contract when they freeze, so the density of a substance's solid is higher then the density of its liquid.
