Binge-watching(刷剧) is when a person watches more than one episode of a show in quick succession(一连串，连续)．With developments in the speed and connectivity of the Internet，increases in technology and the rise of on-demand entertainment companies，people can now have their favorite shows streamed directly to their television at their convenience.
This behavior is nothing new.In fact，“binge-watching” has been officially listed in dictionaries since 2015.The entertainment companies recognize this behavior and many take steps to encourage it.Often，instead of releasing each episode on a week-by-week basis，an entire series will become available concurrently.Once the episode finishes，many platforms will display pop-ups with “you might like” suggestions，or will automatically play the next episode.
However，recent research suggests that out of the more than half of British adults who watch more than one episode of a show back-to-back(一集接一集地)，almost a third have admitted missing sleep or becoming tired as a result; and one quarter have neglected their household chores.Next we’ll be missing work!
Bingeing has other connections—binge eating，binge drinking and binge smoking.All of them are often associated with a lack of control and a possible route to addiction.Lindsey Fussell，consumer group director，said，“The days of waiting a week for the next episode are largely gone，with people finding it hard to resist watching multiple episodes around the house or on the move.” If people find binge-watching hard to resist，are we witnessing the birth of a new type of addiction
The countless number of information and entertainment that television and online media can bring us is，many would say，a good thing.However，when the activity begins to bleed into other areas，causing us to stop functioning then it becomes a problem.So，what’s the answer Moderation! Neither a tiny amount，nor too much.After all，as the old proverb says，“A little of what you fancy does you good.”

What will man be like in the future—in 5,000 or even 50,000 years from now We can only make guesses，of course，but we can be sure that he will be different from what he is today，for man is slowly changing all the time.
1 Man，even five hundred years ago，was shorter than he is today.Now，on average，men are about three inches taller.Five hundred years is a relatively short period of time，so we may assume that man will continue to grow taller.Again，in the modern world we use our brains a great deal.Even so，we still make use of only about 20% of the brain’s capacity.As time goes on，however，we shall have to use our brains more and more，and eventually we shall need larger ones! This is likely to bring about a physical change too：the head，in particular the forehead，will grow larger.
2 In fact，we use them so much that very often they become weaker and we have to wear glasses.But over a very long period of time it is likely that man’s eyes will grow stronger.
On the other hand，we tend to make less use of our arms and legs. 3 At the same time，however，our fingers will grow more sensitive because they are used a great deal in modern life.But what about hair This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. 4
Perhaps all this gives the impression that future man will not be a very attractive creature to look at！ 5 All the same，in spite of all these changes，future man will still have a lot in common with us.He will still be a human being，with thoughts and emotions similar to our own.
A．This may well be true.
B．Let us take an obvious example.
C．Nowadays our eyes are in constant use.
D．These，as a result，are likely to grow weaker.
E．Now how exactly will this great revolution occur
F．In the future，then，both sexes are likely to be bald.
G．We’re all set to get much taller and thinner，if we want to survive.
1．【答案】B
【解析】上文提到人类一直以来都在慢慢变化，下文从身高和脑力运用两方面举例对比五百年前人类与现在人类的区别，故此处起承上启下作用。B选项“让我们举一个明显的例子”符合语境。故选B。
2．【答案】C
【解析】根据下文“事实上，由于我们经常使用眼睛，视力变得越来越弱，我们不得不戴眼镜”可知，C选项“现在我们的眼睛经常被使用”引出下文，符合语境。故选C。
3．【答案】D
【解析】根据前一句“On the other hand，we tend to make less use of our arms and legs.”可知，空格处说明上一句所产生的结果。less use 对应D选项中的 grow weaker。故D选项“结果，这些很可能会越来越弱”切题。故选D。
4．【答案】F
【解析】根据上文“But what about hair This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer.”可知，头发的作用越来越小因而可能消失。由此可知，未来男女将很可能成为秃头。 disappear对应F选项中的 be bald。故选F。
5．【答案】A
【解析】根据前文的举例说明人类的外貌特征的改变，以及上文句子“Perhaps all this gives the impression that future man will not be a very attractive creature to look at！”可知，人类将不再像以前那样好看。该空对上文进行总结。故A选项“这很有可能成为事实”切题。故选A。
语法填空。
While English speakers look back to the time of Shakespeare and Milton 400 years ago as a golden age，Chinese look back far 1. (far)，to the Tang Dynasty 1,200 years ago as their golden age of literature.

1．【答案】further/farther
【解析】考查形容词比较级。结合句意可知表达时间上更远，空格前的far用来修饰形容词比较级。故填further/farther。
2．【答案】that
【解析】考查名词性从句。分析句子结构可知，空格处引导表语从句，从句中不缺成分，用that引导。故填that。
3．【答案】balanced
【解析】考查词性转换。空格处需用形容词作定语修饰名词look。故填balanced。
4．【答案】visually
【解析】考查词性转换。空格处需要副词修饰形容词pleasing。故填visually。
5．【答案】to establish

6．【答案】popularity
【解析】考查词性转换。空格前有such修饰，此处应用名词作enjoy的宾语。故填popularity。

【解析】考查冠词。结合句意可知表示理解这些诗歌是一个挑战，又challenge发音以辅音音素开头，用不定冠词a。故填a。
8．【答案】causes
【解析】考查时态。句子陈述事实用一般现在时，主语是动名词，谓语动词要用第三人称单数。故填causes。
9．【答案】in
【解析】考查介词。in different ways意为“用不同的方式”。故填in。
10．【答案】be caught
【解析】考查动词的语态。主语the core meaning和动词catch之间是被动关系，需要用被动语态，又情态动词can后用动词原形即可。故填be caught。
