I'm Jim. Today is my birthday. I want to thank my family for their love. So I cook dinner for them. I know my mother likes hamburgers and salad. But my father likes chicken and tomato soup(汤). I have a brother. He likes hamburgers, too. But he doesn't like salad. He likes carrots. I have a sister, too. She likes fish(鱼肉) and bread. I like chicken and strawberries. I will buy these things for the birthday party.

    Many people do the same things on their birthday: They have a big cake with lots of candles(蜡烛), and listen to their friends and family sing "Happy Birthday to You".    ①     would you like to pay money to sing that song?

    Can you imagine a sea of sand three times bigger than India? This is the Sahara Desert, the largest desert in the world. It covers 11 countries in North Africa and is over 9 million square kilometers.

    In the Sahara, temperatures are very different during the day and at night. It is much hotter during the day than at night. During the day, the hottest time is between 2 p. m. and 4 p. m.-when temperatures rise to 33℃. But it is very cold at night, the coldest time is at 4 am, when temperatures fall to -1℃.

    Because of the extreme temperatures in the desert, it is a very difficult place to survive (幸存). Marco Rivera, our survival expert, has some tips.

    Take warm clothes and a blanket. You will need a hat, long trousers and a thick sweater to keep you warm at night. During the day, cover your body, head and face. Clothes protect you from the sun and keep water in your body. You will also need a warm blanket at night. It can get cold rapidly. When the temperature drops, it can be a shock and make you feel even colder.

    Try to drink some water at least once every hour. You need your water to last as long as possible. Drink only what you need. If you eat, you will get thirsty and your water will run out soon. You can eat a little, but only to stop you from feeling very hungry. Eat a small amount of food slowly.

    It's important to stay out of the sun during the day. Make a hole under your car and lie there. This will keep you cool and help you sleep. Find a warm place to sleep at night. A small place near a tree or a rock will be the warmest. But be careful before you decide where to sleep. Dangerous animals like snakes also like to sleep in these places. Look carefully for animals before you lie down.

    Rice, meat, vegetables and fruit… there are many different food choices for us to eat every day. You may think that throwing away your leftover food is not a big deal. But you should keep in mind that many people around the world still don't have enough to eat.

    In 2015, there were over 1 billion hungry people in the world, according to the United Nations. Many children went to sleep hungry and 15 million of them even died from hunger.

    However, food waste is still a big problem. The average person throws away 50 kg of food every year. This means that 1.3 billion tons of food goes to waste each year. That is more than one third of all the food we make.

    We could give this leftover food to many people. For example, the amount of food wasted in Europe would be enough for 200 million people!

    So next time you feel picky (挑剔) about what you want to eat or can't finish your meal, you might want to think twice. There are many others who aren't so lucky.
