When Tang Dynasty poet Du Fu (712-770) wrote this poem, he was living in Chengdu. Sometimes he went to farm in the field. The poem shows his care for farmers.

The very first word, “good”, shows the poet’s joy and love for the spring rain. The rain is good indeed, as it “knows” the proper time to come. Here the poet uses personification(拟人), as if the rain were smart enough to know that it should come in time for the farmer’s busy plowing(农耕) season.

When the rain comes, it appears during the night without making any noise. Unlike the thunder(雷) and lightning of summer storms, the quiet spring rain makes its contributions without seeking(寻求) to be known.

In the night sky, the clouds look dark and heavy, indicating(暗示) that there will be enough rain during the night. Then the poet imagines: tomorrow morning, all of the flowers in the city will bloom(盛开) after the rain.

Facial recognition technology(人脸识别技术) is widely used today. For example, police use it to search for bad guys(家伙). It’s also used to unlock phones or doors.

Now, a similar technology, known as facial detection(探测), is entering a new field: the business of advertising.

Such systems are going through tests in a small number of stores. One facial detection system can tell a person’s “happiness” or “fear” level. That helps businesses see how people feel as they look at products or advertisements in the store. Another system can detect whether someone is wearing eyeglasses. If so, stores can send advertisements for new glasses to him.

Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people’s ages and five levels of feelings-from “very happy” to “very unhappy”.

Supporters of the technology say it could improve buyers’ experience by showing products they might like or by offering them products at lower prices.

Some are against the idea of using such systems. Pam Dixon, the head of a privacy(隐私) group, is one of them. She thinks the strange actions may cause something unfair. For example, a business could raise the price of a product according to a person’s age and feelings.

However, one store testing the technology explained they wouldn’t store people’s information like names or ages. And the advertising board system maker said it didn’t keep any personal information or record any videos.

There are certain foods which should never be stored(储存) in the fridge. Some of them may surprise you.

    32     The cold temperature will make it hard. If you have made sandwiches with the bread, then you can store them in it.

We all love to have tomatoes.     33     The cold air in the fridge stops the ripening(成熟) process. And as we all know, ripening is what gives every tomato more taste. For best results, keep them out.

    34     It needs no help from us. Putting it in your fridge will in fact increase the speed of the crystallization(结晶). This will make honey harder or nearly impossible to use.

If you haven’t opened your watermelons, then there’s no need to put them in your fridge. Research has shown that watermelons can be stored in room temperature.     35     Watermelons that have been cut open should be put in the fridge. What’s more, they should be covered.

Cucumber(黄瓜) enjoys room temperature.     36     Cool temperature can make cucumber’s skin(表皮) go bad faster, so find a dry and cool place at room temperature for your cucumber.

How do you feel about your looks? Is it important     62     have a beautiful face? Are there other things that can make a person special? The way you look is special.

Sometimes, we might feel bad about looking different. We might feel like we look ugly or strange. But our differences are what make us special.

I recently watched a speech by a man named Robert Hoge. He was born with     63     strange-looking face. His mother always worried     64     he would face many difficulties in life. But what Hoge did changed his mother's mind little by little. He sometimes     65     made fun of by strangers. But he didn't care about it     66     all. He decided to accept his face and feel confident.

It's hard when you feel you don't look "normal" or "perfect". But the truth is, no one is perfect. The important thing to remember is that you are special, no matter what you look like.
