In the 2lst century people often join a“group chat”on Wechat, share videos on Douyin and give opinions on Facebook. We live in a world that has accepted the social media(媒体)wholeheartedly. Being the international common language, English has lent itself willingly to be used on social media, experiencing many small but important changes during the process.What are the effects of the social media on the English language?

? Old words but new meanings

When someone wants to post something on his“wall”, why do we think of the homepage of his Facebook, and not the walls in his house? This is the magic of social media. We know“friend”is a noun, but now it's also used as a verb. “friended”and“unfriended”mean the process of adding or deleting someone from your list of friends.

?__________________________

Social media has invented new words like“selfie”or“emoji”to describe the new things. The most famous of these words perhaps is “google”which is used more than the old-fashioned simple word“search”.Generally speaking, a new word should be in use for at least 10 years before being entered in the Oxford English Dictionary. However, the dictionary officially included the word“tweet”.

?Introducing acronyms(缩略词)

LOL (Laugh Out Loud). OMG (Oh My God) and BRB(Be Right Back)are examples of acronyms, the same as IDK(I Don’t Know)and TTYL(Talk To You Later). We need them to be short in length on social media, so we use acronyms to take the place of these phrases.

Social media is without doubt here to stay. In the future, it's likely to develop to a greater degree and take the English language along with it on the road of development.

Have you stroked (抚摸) a cute dog recently? If that dog touched you with its nose, you might find how wet and cold it was. If dogs are so warm and fluffy (毛茸茸 的), then why are their noses so cold?

Before, people thought that dogs had cold noses to help them control their body temperature. But, a new study in the journal Scientific Reports has shown some interesting findings about dogs’ noses. The study found that when the air temperature was 30 ℃, the tip of a dog’s nose is about five degrees cooler than the air. But why is this?

The researchers believed that the tip of a dog’s nose has a special sensory function (探测功 能). So, they did an experiment to test it. The study showed that dogs could find weak heat sources—like a small animal—with their noses from 1.5 meters away.

The research team studied three dogs named Charlie, Delfi and Kevin. For the experiment, the dogs had to tell the difference between two objects. The two objects were heated to different temperatures. Amazingly, all three dogs were able to sense the temperature difference between both objects.

The study also found that the heat from the objects in the experiment “was too weak to be felt by human hands, even at very short distances”. The dogs were able to sense these heated objects from a distance, but humans were only able to feel the warmth of the object if they touched it.

To know more about it, the research team also studied the brain activity of 13 dogs. When a warm object was put near their noses, there was an increase in brain activity.

“From the two complementary (互补的) experiments, we can know that dogs are indeed able to sense heat from warm-blooded animals, and a special region of the brain is made to be active by such heat.” said Anna Balint, the leader of the study.

1.What did the new study published in the journal Scientific Reports find about dogs?

C.How dogs feel heat better. D.How a dog’s temperature influences its brain activity.

2.Which of the following words has the closest meaning to “region”?

A.Way. B.Area. C.Type. D.Change.

3.What happened to the dogs when a warm object was put near their noses?

A.They showed no change in their brain activity. B.They had different kinds of excitement.

C.Their brain activity slowed down. D.Their brains became more active.

4.What can we infer from the passage?

A.Heat sensing ability can help dogs hunt for food.

B.The tip of a dog’s nose has a special sensory function.

C.Dogs are smarter than other animals.

D.The two experiments found different results.
