I said to her, “I am in no ________. Go ahead.” She told me she worked at a nearby restaurant while ________ for a certain brand.

She asked, “What do you do when people are not ________ to you?” “I just smile. Then I tell them that I am doing the best that I can. I usually make ________ feel better by thinking they are probably having a bad day.” “Thank you,” she said with a big smile, “Your words are helpful to me.”

In our communication, I showed her there were ________ and kind people in the world. I hope she ________ our conversation each time someone is impolite to her.

A much-used home appliance suddenly stops working. You look at it helplessly.     71    

It’s a hard question that almost every family has faced. There are so many things to consider, from the cost to the influences on the environment.     72     Just imagine living without a fridge in the summer.

In a recent survey, more than 95 percent of the 11, 350 people who did the survey chose to repair a broken appliance. Only three percent chose to replace the appliance. Did each of them make a smart decision? In my opinion, one great way of looking at the problem is to work out the present value of your appliance. When you buy a new home appliance, write down its cost and the number of years you expect it to last.     73     This will tell you how much value the appliance loses each year. When the appliance breaks down, you can quickly work out its present value. If a repair costs more than the appliance’s present value, you should replace the appliance.     74     According to this theory (理论), if a washing machine breaks down when it is eight years old, you should replace it. For fridges and ovens, that number is nine. And for cleaners, it’s seven.

What do you think of my theory?     75     Have you ever felt sorry about your decision?

The South Pole is always icy. The Antaretic ice sheet (南极冰盖) covers thousands of miles and Antarctica is under 1.6 miles of ice. Recently, scientists have discovered that the land under the ice is a large hidden landscape that has been frozen for millions of years.

The scientists discovered that under the ice it is a landscape with hills and rivers everywhere. This secret world is greatly large, covering across 12,000 square miles. Time seems to stop in this frozen world, keeping its mysteries for millions of years.

To research this hidden land, scientists used a cool technology called radio-echo sounding. It’s like sending wave from a special plane flying high above Antarctica. These waves bounce off (反弹) the land below, creating a kind of map. The scientists then studied this map to learn more about what was hidden under the ice. Scientists also looked at satellite images (图像). Satellites are like our eyes in the sky, travelling around the Earth and taking pictures. By studying these images, a picture of the land under the ice appeared.

This hidden world wasn’t always icy. A long time ago, not only rivers, hills, and forests were there, but also it even hosted different forms of life, including animals walking around and enjoying the landscape. But then, something unexpected happened. The land got covered in ice, freezing everything. This freezing event happened more than 34 million years ago, making it an ancient landscape.

Now, scientists are not just wondering about the past; they’re also worried about the future. They’re worried about global warming. The worry is that the ice in Antarctica might melt (融化), changing everything. Even though the Earth is warmer than in the past, scientists hope it won’t get too warm. The hidden land is quite far from the ice, giving some hope that it might not melt too quickly.

Yet, the mysteries continue. Scientists believe there’s more waiting to be discovered. Every fact that people discover opens the door to more questions about our planet’s past and future.
