【題目】 Thanks to our mastery（精通）of engineering and technology, the world is changing at a lightning quick pace, much quicker than ever before.

Engineers design and create things like machines, structures and processes. They use a combination（結(jié)合）of math and science to make these things work（or make them work better）Engineers change the world around us and come up with technologies and creative solutions to make our lives more comfortable, and make the world a better place.

Cool jobs in engineering and technology.

Engineers affect almost every area of our lives. Let's take a look at some of the coolest jobs you can do as an engineer.

●Roller coaster engineer

Have you ever visited a theme park and thought how cool it would be to create your own roller coaster? Well, that's the job of engineers-from designing them to analyzing the speed and weight of the roller coasters to make sure they are safe and run smoothly. What a scream!

●3D printing specialist

The future is all about 3D printing. As the technology becomes more widespread, it'll be used to print everything from food to prosthetic limbs（假肢）. Engineers such as software specialists and machine programmers will be in high demand to run this new technology.

●Space exploration engineer

From designing the powerful rockets to send deep into space to building and programming rovers（探測(cè)器）that can find out water on planets like Mars, engineers are at the center of space exploration and at the heart of what companies like space organizations like（美國(guó)國(guó)家航空航天局）do.

【題目】 My parents taught me not to waste food. My mom always found ways to make leftovers (剩余食物) taste good. I went to Italia to learn about some of their special foods. As I was there, I learned about the food and the history of the area. I learned that they don't waste food, either, and they use leftovers!

Many years ago, there was not enough food for everyone. People learned to cook and eat almost everything. They had to think of ways to make special dishes. One of these dishes is kao zha. It's made with leftovers like meat, soup, oil and fat. That might not sound very good, but it does taste good. Today, kao zha is a special dish at big banquets (宴會(huì)).

Another famous dish is called zao bing. It's made with fruit, meat and other things. I really liked it! But I didn't want to cat too much. It has a lot of fat in it.

I smelled something burning and I saw smoke, so I found another special food of the Italian area -duck meat. The duck meat is put in a big oven to cook it. Smoke keeps the meat fresh. I don't usually cat meat, but this duck meat was delicious! It tasted sweet.

Italia is a great place with delicious food. I hope I can come back again!

【題目】 Everyone needs friends. There is an old saying, “Friends are God's way of taking care of us.” But how do you find real friendship and keep it?

First, you should choose a friend. What makes a good friend? It is not because a person has money or good looks. A good friend should be kind and patient. For example, if you have a bad day, a good friend should listen to your complaints(抱怨)and do his or her best to help you. To make a friend, you can't be too shy. You should make each other happy and share your life.

But things cannot always be happy. Even the best friends have fights. What should you do when you have a fight with your friend? You have to talk to him or her. When there is no one around, talk to him or her honestly. If he or she doesn't want to talk, you can write a letter.

There are some steps to be friends again. Tell him or her how you are feeling; say what your friend did is wrong and explain why you did this or that. Remember that friendship is the most important thing in your life.

1題完成句子；2～3題簡(jiǎn)略回答問題；4題寫下第四段的主題句；5題將文中畫線句子譯成漢語(yǔ)。

【題目】根據(jù)短文內(nèi)容，完成圖表中所缺信息。

Christmas is one of the happiest times of the year. It’s time we spend with family members, giving gifts to each other and eating plenty of delicious food. However, at the same time it can also be a nervous time. You have to spend much time and money planing and buying presents for everyone. You need to clean the rooms or even clear some of them out and put up the Christmas tree, the decorations and the balloons. And you have to communicate with your friends and relatives whom you perhaps wouldn’t usually spend so much time with. So what can we do to deal with these things to enjoy the happy season to the fullest?

Usually, you have to face the busy shops to do your Christmas shopping during this holiday. That can make you stressed out. To stay calm (冷靜的) during this holiday, you can start your shopping early. In other words, you can buy presents for people before Christmas comes so that you can save yourself some money. What’s more, you can buy your presents on the Internet, which means that you can find anything you can think of, and you can do it in your living room. It’s much cheaper, so you can save money.

Did you once drink more than usual, eat cakes you didn’t want or do something else which leave you feeling tired? Remember that it’s your right to enjoy Christmas the way you want to and that you should take no notice of those who tell you that you’re not being Christmassy.

Finally, you’d better have low expectations (期望). If your expectations are high, you will make yourself upset. Don’t let yourself be pressured (迫使) into making the Christmas perfect. So, just be satisfied to have a pleasant evening with your family and let what happens happen.

How to solve Christmas 【1】

Introduction

Christmas is a happy family time but it also make us nervous.

Causes

We have to spend much time 【2】 for the holiday and communicating with friends and relatives.

Ways

◆ Do shopping 【3】, such as doing Christmas shopping online in advance.

◆ Learn to 【4】 and spend Christmas in your own way.

◆ Don’t expect too much to 【5】 getting yourself upset.
