I scroll my notebook pages before the first class of the new term.新学期第一节课前，我翻看笔记本的页面。 The syllabus lists four discrete ideas.「教学大纲」上列着四个「离散的」小概念。 One page is about a fungus.一页讲的是「真菌」。 Another page is about a consonant.另一页讲的是「辅音」。

Our teacher said a fungus is not a plant.老师说「真菌」不是植物。 Wet rainfall helps it grow on old bread, and it sends out an enzyme to break the bread down into sugar.潮湿的「降雨」让它在旧面包上生长，它还分泌「酶」把面包分解成糖。 Now it takes the sugar inside through its membrane, along a gradient.接着糖沿着「梯度」通过它的「细胞膜」进入里面。 A receptor on that membrane feels the sugar and lets it in.那层「细胞膜」上的「受体」感觉到糖，就让它进来。

Innate defense works the same way in your body.「先天」的防御在你身体里也是同样的道理。 It acts at once, without any learning or memory.它立刻起作用，不需要学习，也不需要记忆。 A capillary is the smallest kind of blood vessel.「毛细血管」是最小的一种血管。 It is so thin that only one cell can pass.它细得只能让一个细胞通过。 A consonant is simply a speech sound that is not a vowel.「辅音」就是像波或克那样短促的语音。

The syllabus also asks us to write each word in a sentence.「教学大纲」还要求我们把每个词写进句子里。 I read my notes again on the bus.我在公交车上又看了一遍笔记。 Now the four pages feel close and clear.现在这四页内容感觉又近又清楚。
