Fireworks have been enjoyed by countless people ever since they were invented in China during the Tang Dynasty hundreds of years ago. From small family gatherings (团聚) to huge global celebrations, there isn’t a party that couldn’t be made more fun with a few fireworks. But it seems that there’s a big price to pay for some brief beauty and fun.
It’s been discovered that fireworks contain metals such as copper (铜) and lead, in addition to other pollutants like perchlorates (高氯酸盐). According to the Environmental Protection Agency, perchlorates can form naturally or be made. They are an industrial chemical used in rocket fuel and explosives (炸药), and are soluble (可溶解的) in water.
This is a reason for concern because perchlorates negatively affect the thyroid gland (甲状腺), which influences important bodily functions like blood pressure and heart rate.
Furthermore, a study conducted by Terry Gordon, a professor at New York University, examined the emissions(排放物) whose sizes were big enough to enter the lungs. They concluded that these emissions may lead to various dangerous conditions like cancer, heart attacks, and strokes (中风).
It is worth noticing, however, that no studies have proven the connctions between these conditions and the dangerous chemicals in fireworks.
However, the negative effects of firework emissions can be observed in birds. Britain’s Royal Society for the Protection of Birds warns against setting off fireworks close to wildlife areas as they may cause confusion among birds.
In 2010, an incident involving 5,000 red-winged blackbirds falling out of the sky on New Year’s Eve in Arkansas, US supported this idea. A fireworks display held at a nesting ground for blackbirds led to the birds’ night sight being affected, causing them to fall to their deaths.
Arguably (可以说), the use of fireworks during celebrations may be because people don’t realize how they pollute our environment. Companies and researchers could take this cue (线索) and find other new, eco-friendly ways.
After all, for all the beauty fireworks bring, there’s no better beauty than that of our planet’s.

It’s often said that the rise of social media has revolutionized (彻底改变) communication. With smartphones and social networking apps, we can write to our family and friends whenever we like. But while social media has brought us convenience, it also has its problems, such as misunderstandings in communication.
Quite often, people misunderstand what’s written on social media. According to a story published on The Conversation on March 8, sarcasm (讽刺), in particular, can be very difficult to notice in a written message.
Sarcasm is a kind of irony (反语): It’s when we say something, but really mean the opposite. For example, a message from a friend the day before a math exam that says “I’m so looking forward to tomorrow!” is obviously sarcasm.
Sarcasm before the rise of social media and mobile phones was mostly used in speech and face to face. That made sarcasm easier, because you could accompany your words with a facial gesture and a tone (语气) of voice that would help others get your message. You had a good chance of being understood and receiving a laugh or an understanding glance.
And yet when we text or write something online, a lot of that information goes missing. “There are no facial hints, no tones or maybe even a delayed response if a person can’t text you back immediately,” wrote The Conversation. “And if you don’t know the person all that well, there goes your last possible hint: history.”
To help avoid misunderstandings, people who use platforms such as Twitter often include the hashtag ﹟sarcasm – although this is like having to explain a joke when people don’t laugh at it, which destroys the point of sarcasm in the first place.
And it isn’t only sarcasm that can get lost in electronic communications. It’s also hard to notice things such as indifference (冷漠).
“One of the problems with digital communication, when it relies purely on text, is that this sucks (抽离) the empathy (情感共鸣) out of the communication. So it can lead to miscommunication,” linguist Vyv Evans, author of The Emoji Code, told USA Today. “This is where emojis come into their own. They put the body language back, so people can better read emotional intent (目的).”
However, even though there are hundreds of different emojis(表情符号) to choose from, there’s still no replacement for good old-fashioned face-to-face communication.

A.They can’t wait to take the exam.
B.They are well-prepared for the exam.
C.They’re not looking forward to taking the exam at all.
D.The exam might be too difficult for them.
2.What might lead to the words we write online being misunderstood, according to the Conversation?
A.The use of new internet words and phrases.
B.The complicated relationship between people.
C.The absence of facial expressions and tones.
D.Responding to other people too quickly.
3.What does Vyv Evans think is a possible way to avoid miscommunication online?
A.Using emojis, as they can display body language.
B.Expressing fewer personal feelings.
C.Sending voice messages instead of text messages.
D.Using a hashtag before making jokes.
4.What is the article mainly about?
A.The convenience of online communication.
B.Some misunderstandings that come with digital communication.
C.A good replacement for face-to-face communication.
D.Some reasons for the popularity of emojis.
Slang(俚语) is very informal language which is often used by young people. It’s hard to keep up to date with it as new words and phrases appear and evolve (发展). Living in a multicultural society has an effect on language, especially on the young, whose friends are often from a mix of backgrounds. TV and music also have a big impact. A complete list of slang is difficult to make; by the time it was finished, the list would be out of date. However, here are a few examples:
Safe, sorted, sound, cool or wicked all mean “That’s good” or “I understand”.
Instead of using different tag questions (附加疑问句) like “… isn’t it?”, “… can’t you?” or “… don’t they?”, people use “innit”.
For example, “He can dance really well, innit!” (= He can dance really well, can’t he?) or “They always say that, innit.” (= They always say that, don’t they?)
Instead of saying “very”, “really” or “completely” use “well”, for example, “I’m well tired” or “You got it well wrong!”
“Whatever” means “I don’t care”, for example, A: “But the teacher says we can’t leave until we’ve finished.” B: “Whatever. I’m going.”
“He’s fine” or “he’s fit” both mean “He’s good-looking”. Fine and fit can describe a boy or a girl.
Not everybody uses slang and not everybody likes it. A school in the north of England recently told its pupils to stop using slang words such as “hiya” (hello), “cheers” and “ta” (both mean “thank you”) if they wanted to get a place at university or a good job.
When British people use language like this, it’s no surprise that some say they can’t understand native speakers. But perhaps learners don’t need to worry so much. Research shows that most of the English spoken around the world today is between non-native speakers of the language.
So, how important is it to understand these slang words and expressions? If you watch films or TV in English, read magazines in English, chat online in English or are interested in English song lyrics, then understanding slang can be very useful. You probably won’t see much slang in your English examination, though.

On the first day of my part-time job, I woke up early than usual, excited but nervous. I said to me, with a mixture of these feelings, that it would be a easy job. However, things didn’t happen as I had expected. I entered the shop that I would spend the next couple of weeks serve coffee and food. After training, my first customer finally appeared. He ordered for a cup of coffee and two dish. Ignoring the shop’s rule, I carried the food without a tray. I was about to reach the table when one of the plates fall noisily to the floor.
