【題目】German Chancellor (總理) Angela Merkel may look like an ordinary woman. She dresses commonly and doesn’t show many feelings. But don’t let appearance fool you.

As the first woman chancellor in Germany’s history, Merkel has topped Forbes magazine’s list of “The World’s 100 Most Powerful Women” six times. She has even been compared to Margaret Thatcher and many people call her “Iron Lady”.

Through her political career, Merkel’s persistence(堅持) and patience helped her a lot.“She’s bright and open-minded,” said Hubert Markl, a German biologist. “She is the person who wants to know exactly what is going on, and how never giving up will influence our society and future. ”

【題目】Nowadays, with the development of the Internet, emoji(表情符號)are more and more popular among netizens(網(wǎng)民). Some people even feel difficult to talk online without using emoji. Emoji help netizens to communicate with each other easily and vividly(生動地). Yet, not all emoji are properly used on social media. So we are going to introduce some common but confusing(令人困惑的)emoji to help you have a better understanding of these small signs.

1. A recent survey shows, over 53% people use the emoji when they are chatting online. Some people think it means “I’m shy,” but others only use it when they are surprised or shocked. But what does it really mean? It is still an unsolved question.

2. What do you think of this sign? Believe it or not, 80% of netizens use it under the meaning of “It is not funny at all, but I have to smile.” Is it right? Of course not! It actually means that “I saw what you did(usually bad things) and I want to give you a sinister(奸詐的)smile.”

3. People have very different opinions on this emoji. The Apple company has told that this emoji means “high five(嗨，擊掌).” But most people still use the incorrect meaning—“pray”. Some netizens even thought, “If you see this emoji as two people give each other a high five, you must be a bad guy.”

4. According to the official guidelines(官方指南), it is used as “smile through tears(破涕為笑).” However, most young netizens consider this emoji as “Laugh to tears” or simply “LOL”, which means “Laugh out loud”.

You see, emoji are also a kind of language. And different people have different understanding of them.
