A crocodile can go through 8,000 【4】(tooth) in one lifetime!

What does the expression “crocodile tears” mean? Simply put, “crocodile tears” are fake sadness. You pretend 【5】(cry) and feel bad for something when in fact you could not care 【6】(little). A great word to describe it is insincere. The phrase “crocodile tears” comes from an old myth that crocodiles would shed tears while eating their prey. A religious worker wrote that 【7】 a crocodile found a man by the water, it would kill him if it could. Then the crocodile would cry tears on the man, but then finally swallow 【8】(he). Another myth suggests【9】crocodile is very clever indeed. Crocodiles, the story goes, would cry tears as a false show of guilt or sadness to trick their prey. The prey would come closer and then become dinner.

Scientists explain that crocodiles DO create tears, but they do not cry. The tears help to clean their eyes. Crying is purely emotional and it 【10】 (reserve) for us humans.

【題目】 “You totally missed out!” This sentence strikes fear in the hearts of teenagers more than almost anything else. In fact, missing out on something bothers most teenagers so much that there is even a special word for that sick feeling: FOMO. 【1】 FOMO, which was added to the Oxford English Dictionary in 2013, refers to that anxious feeling people get when they realize they are not attending a social event.

【2】 In fact, one survey found that two-thirds of people in this age group admitted to experiencing FOMO regularly. If you ask teenagers whether they experience social media anxiety, most would answer no. But what they do not realize is that if they are stressed or worried about what they see online, then they are possibly experiencing FOMO, especially if they are online a lot.

Then how to handle the problem of FOMO? Of course, turning off the technology seems like a natural cure for FOMO. 【3】 Teenagers may still worry that they are missing out, even if they are not on social media at all.

The key is to turn off the technology and do something else like reading a book, giving a friend a makeup, baking cookies—anything that allows them to focus on something other than social media. 【4】

It is also important to encourage teenagers to recognize that they cannot possibly be everywhere and do everything. So, naturally, there will be parties or events that they cannot attend. 【5】 Photos can be deceiving (騙人的). And even though it looks as if their friends are having a good time, this may not be the case. They should never let the fact that they couldn’t be somewhere affect their view of themselves.

A. FOMO has become an even bigger problem.

B. FOMO is especially common to people aged 18 to 33.

C. In simple terms, FOMO stands for “fear of missing out”.

D. It can be extremely helpful in changing their attitudes towards life.

E. But this does not necessarily mean they are missing out on something.

F. By doing this, teenagers are not glued to their screens and are more active.

G. But just switching the phone to “off” doesn’t erase the feelings caused by FOMO.
