第34课 大麦
I know some children who are very fond of growing seeds of all kinds in pots. Sometimes they fill a flower-pot rather more than half-full with moist sand. On the top of this damp sand they sprinkle some grains of barley, and then they cover them well with more sand.
我认识一些小朋友，他们非常喜欢在花盆里种花，什么种子都种。有时候他们在花盆里装上大半盆湿沙子，在沙子上面撒上点儿大麦粒，再用沙子盖住。
The sand is kept moist, and in a week or two the children are glad to see pretty little green shoots of grass growing up.
保持沙子的湿润，过一两个星期，小朋友们就能高兴地看见，绿色的草芽长出来啦！
But can grass come from barley seeds? Yes; barley is a kind of grass. And wheat, oats, rye, rice, and maize 2 are also grasses, which once grew wild in the fields. These grasses have now been taken care of, or cultivated, for thousands of years;and so they have become much larger than the grasses which we still find growing wild in the lanes and meadows.
但是，大麦粒也能长出草来么？能。大麦也是一种草。小麦、燕麦、黑麦、稻米、玉米也都是草，以前是在野地里野生的。人类的祖先把这些野草栽种，也就是“培养”了上千年，于是它们长得比野草个头大多了。现在，我们在乡间小路和草地上，还能找到这些野草呢。
We shall not likely get barley plants grown in pots to produce flowers or seeds; for to do that they need the earth, and the rain, and the bright sunshine, which they get in the open fields.
花盆里的大麦植株，是不大可能开花结果的，因为，大麦要开花结果，需要足够的泥土、雨水，还有明亮的阳光；这些只有在屋外的田野里才能得到。
The barley plant has long slender green leaves, and a hollow, jointed 3 stem. At the top of each stem, a number of tiny green flowers grow one above another in the form of a spike 4. Each little flower forms a seed; and then the flowers drop off, and the seeds swell 5, while the green stem turns to yellow straw.
大麦植株，长着又细又长的绿叶，和一个中空、分节的茎。茎的顶端，有很多绿色的小花，上下排列，样子就像一个锥子。每朵花都会长出一个种子，然后花就凋谢了。种子会长大，绿色的茎也会变成黄色的麦秆。
