【题目】
Scientists have discovered a new kind of invisible ink. It’s called water. And all you need for this secret-messaging ink to work is to write with it on a super-hi-tech piece of paper coated with special chemicals. 【1】 It shows up darker than the surrounding paper under UV(紫外线的) light.
When the message has been read and needs to be hidden again, get out your hairdryer, and blow some warm air on the paper. 【2】
Using hot air from a hairdryer for 15-30 seconds, you were able to reuse the special paper up to 30 times because the heat reorganized the chemical structure of the paper coating. 【3】
The invention was made by a group of scientists in China, led by Qiang Zhao of the Institute of Advanced Materials, Nanjing University of Posts and Telecommunications.
Although much of modern communication is digital(数码的), there are still some situations in which it is important to send messages on a piece of paper, such as when the people don’t have Internet. 【4】 But the problem has always been how to get rid of a message once it has been shown so no one else can read it.
【5】. To use it, write with the lemon juice on ordinary paper, iron(熨) the paper with a hot iron and the hidden message will appear. The downside(缺点) is that the paper has to be destroyed to hide the message so no one else can read it.
A.How to make the invisible ink? Follow the steps.
B.Invisible inks have long been used to send secret messages.
C.Without the heat, the message stayed visible for up to three months.
D.Previously, the most readily available invisible ink was lemon juice.
E.Shine a UV light on the coated paper and the water message becomes visible.
F.Then the message will be gone and the paper can be reused, which keeps costs low.
G.Putting water on the paper broke up the structure of the chemicals it was coated with.

Dear Jack,
I’m sorry to hear that you feel lonely in the new school, because you find hard to make friends. Now, I’d like to offer you any advice.
Firstly, it’s normal for you to feel lonely because you were living in a new environment. Secondly, you should greet your classmates when met them on campus. Thirdly, it will be a good idea if you take an actively part in class activities, what can help them learn more about you. I believe you will be able to make new friends soon unless you’re friendly to the others.
I hope the suggestion above will be helpful to you and everything will be fine with you for the future.
Yours,
Li Hua
