The English language has many ways to talk about something that is funny. {#blank#}1{#/blank#} It is a basic human need. Physical humour, especially, can cross limits like nationality and language and bring people together from all different walks of life.
Humour comes in many forms. The most obvious and traditional way we use humour is in jokes. {#blank#}2{#/blank#} This is when a person changes a word or uses it in a different context(上下文) for comic effect.
Another way people can use humour is through telling a funny story. Perhaps something bad happened to the person but they can laugh about it now. People also invent funny stories in order to make people laugh. The advantage of this is that the characters aren't real. {#blank#}3{#/blank#}
Physical comedy usually divides opinions. For some, seeing someone fall down, whether it is planned or not, is one of the funniest things they can see. {#blank#}4{#/blank#} Some types of humour can also be harmful if someone is not in the mood for being made fun of!People's senses of humour vary across the world, so what may be funny in your country might be incredibly harmful in another!
{#blank#}5{#/blank#} The British, for instance, are famous for their humour in English. However, people learning a foreign language face much difficulty when it comes to being funny in a second language.
A. Humour is just one of the ways.
B. Everyone needs to laugh once in a while.
C. Other forms of humour are word play and puns(双关语).
D. Therefore, you don't have to feel bad for laughing at them!
E. People of all ages and cultures have a strong sense of humour.
F. Most people know how to use some form of humour in their native languages.
G.For others, finding physical humour and non-serious accidents funny seems cruel.

Dearest darling girl,
Today is the beginning of the next stage in your life. We head off to your new home at Stanford. Where do I start in telling you how proud I feel to be called Mummy by you? We've laughed at how you burst into this world with a scowl on your face, how determined you have always been right from feeding yourself to making big decisions for your life. There were days during your illness that I wasn't sure you had the will to make it. Telling you that you needed to want to get better was the hardest and yet the greatest day. From that day you took responsibility and decided you wanted to beat anorexia(厌食症).
I don't think I've ever felt so proud of you as when you came home to say that you wanted to go to West Africa between school and university. You chose to go alone, and to raise the money yourself. You have such strength of character and determination. It is at times hard to believe that you are only 18. You experienced something in that month that few dare experience in a lifetime.
So, Viv, here are my words of wisdom to you as you start your next big adventure. The world is a beautiful place but often a few things can make it seem difficult. God's temple is made of love. It's man's temple that is built of stones. Open your heart to goodness and never ever let negative people or thoughts take hold of you. As Minor Myers put it, "Go into the world and do we'll. But more importantly, go into the world and do good:'
It is true that with every passing day, I will grow older and weaker. A day may come when I will become forgetful. But even then, you with your bright smile, will light up my heart.

阅读下面短文,从短文后各题所给四个选项(A、B、C和D)中,选出可以填入空白处的最佳选项,并在答题卡上将该项涂黑
Many people think that babysitting is one of the1jobs for young people. They imagine a teenager putting a few well-behaved children to bed and then continuing to watch television until the parents return home to hand over some money. Well, I can tell you how2that thought is.
I now work all3on Wednesdays for a Ukrainian family with three young boys. In the early morning, I go there to 4the older two while their mother does her jobs or takes care of her six-month-old baby. However, I am also there to5their English by teaching them songs and games in my native language.
Now, four months later, I get home at the end of the day6exhausted!Babysitting is not a job for the7or the weak. I expected8children who would behave well and listen to me all the time. 9,I don't think those kind of children exist at all. While my two boys are usually polite and calm, they are10children and also like to fight, scream and lose their temper for no real11. I often have no idea why they cry together.
Being a babysitter requires you to play a hundred different12throughout the day. I have to be a friend when I play with the boys, but their 13when I tell them to do something. When they hurt themselves, I have to be their14, and when they fight over15 things like sharing their crayons(彩笔),I have to be a negotiator(调停者)。 When lunchtime rolls around, I am a(n) 16to prepare the meal and then a maid as I clean up after lunch. Finally, in English, if someone is very17, we say they have the “Patience of God”. I think I embody(体现) this 18sometimes!
Despite the19involved in my job, I usually do enjoy it. Working with children is so tiring that I always feel20after leaving them with their parents at the end of the day!

【进行实验】该小组按上述实验设计,在一定温度下进行了实验,测得下列数据:
①反应前玻璃管和内盛氧化铁粉末的总质量66.0g(玻璃管的质量为60.0g)。
②反应后玻璃管和内盛黑色固体的总质量m(冷却到室温称量)。
