Planted on my home balcony a morning glory, the flower that it opens but beautiful.
我家阳台上种了一盆牵牛花，它开的花可漂亮了。
Every morning, morning glory blossoms with the wind, the mood that lets me becomes very happy, beautiful appearance resembles a horn, also resemble funnel, we call it ” of “ morning glory again, its leaf is green green, submit heart form, its cauline Teng climbs very high, twine the baluster in the balcony to go up. I discover a strange phenomenon, early morning morning glory is blue, midday, morning glory is gules, is this why?
每天早上，牵牛花就迎风绽放，让我的心情变得很愉快，花的样子像喇叭，也像漏斗，我们又叫它“喇叭花”，它的叶子绿绿的，呈心状，它的茎滕爬得很高，缠绕在阳台的栏杆上。我发现一个奇怪的现象，清晨牵牛花是蓝色的，中午，牵牛花是红色的，这是为什么呢？
Do I ask mom why morning glory can become angry? Mom says we do an experiment to look first, above all the cup that we prepare two outfit water, white composition vinegar is added in a cup, suds is added in another cup, next we put two morning glory scissor that opening into two cups respectively, I observe by, passed probably 20 minutes or so, I discover those who put the morning glory inside the cup of white vinegar to become amaranth, of the morning glory inside the cup that puts suds or blue. Because there is element of a kind of cyanine in morning glory,mom says, cyanine element becomes blue in alkalescent environment, red becomes in the meeting in acidity environment, so morning glory changes with respect to what can let the acid-base value in air and present a different color. Oh, I understood eventually.
我问妈妈牵牛花为什么会变色？妈妈说我们先做个试验看看，首先我们准备两个装水的杯子，一个杯子里加白作文醋，另一个杯子里加肥皂水，然后我们把两朵正在开放的牵牛花剪下来分别放进两个杯子里，我在旁边观察，过了大概二十分钟左右，我发现放白醋的杯子里面的牵牛花变成紫红色的了，放肥皂水的杯子里面的牵牛花还是蓝色的。妈妈说因为牵牛花里有一种花青素，花青素在碱性环境中变成蓝色，在酸性环境中会变成红色，所以牵牛花就会随空气中酸碱度的变化而呈现出不同的颜色啦。哦，我终于明白了。
Morning glory is really strange spend beautifully again.
牵牛花真是又奇怪又漂亮的花。
