Languages have been coming and going for thousands of years,but in recent times
there has been less coming and a lot more going.When the world was still populated by
huntergatherers,small,tightly knit(联系) groups developed their own patterns of
speech independent of each other.Some language experts believe that 10,000 years
ago,when the world had just five to ten million people,they spoke perhaps 12,000
languages between them.
Soon afterwards,many of those people started settling down to become farmers,
and their languages too became more settled and fewer in number.In recent centuries,
trade , industrialisation , the development of the nationstate and the spread of
universal compulsory education,especially globalisation and better communications
in the past few decades,all have caused many languages to disappear,and dominant
languages such as English,Spanish and Chinese are increasingly taking over.
At present,the world has about 6,800 languages.The distribution of these
languages is hugely uneven.The general rule is that mild zones have relatively
few languages,often spoken by many people,which hot,wet zones have lots,often
spoken by small numbers.Europe has only around 200 languages;the Americas about 1,
000;Africa 2,400;and Asia and the Pacific perhaps 3,200,of which Papua New
Guinea alone accounts for well over 800.The median number(中位数) of speakers is a
mere 6,000,which means that half the world's languages are spoken by fewer people
than that.
Already well over 400 of the total of 6 , 800 languages and close to
extinction(消亡),with only a few elderly speakers left.Pick,at random,Busuu in
Cameroon(eight remaining speakers),Chiapaneco in Mexico(150),Lipan Apache in the
United States(two or three) or Wadjigu in Australia(one,with a questionmark):
none of these seems to have much chance of survival.

Sweetest Day is celebrated on the third Saturday in October as a day to make
someone happy. It is an occasion which offers all of us an opportunity to
remember not only the sick, the aged, and children who have lost their parents, but
also friends, workmates, relatives and neighbours whose helpfulness and kindness we
have enjoyed.
Over 60 years ago, when a Cleveland man noticed that some people, such as children
who lost their parents and patients who lay in bed, too often felt forgotten and
neglected,_he developed in his mind the idea of showing them that they were
remembered.He did this by giving them small gifts. With the help of his friends
更多资料添加微信号:hiknow_007 淘宝搜索店铺:乐知课堂and neighbours, he gave those people small gifts on a Saturday in October. During the
years that followed, other Clevelanders began to take part in the celebration, which
came to be called “Sweetest Day”.Over time, the Sweetest Day idea of spreading
cheer to the poor, the sick and children who had lost their parents was broadened to
include everyone, and became an occasion for remembering others with a kind act or a
small gift. Soon the idea spread to other cities all over the USA.
Sweetest Day is not based on any single group's religious beliefs or on a family
relationship. It is a reminder that a thoughtful word or deed enriches life and gives it
meaning.Because for many people remembering takes the form of gift giving,
Sweetest Day offers us the opportunity to show others that we care, in a positive way.

As a teenager, I hated Physical Education lessons.I was not very good at
sports, and I hated team sports because I always felt like I was disappointing the rest
of the team. I was always making up excuses to get out of such lessons.
When I started university, I decided to try kung fu. To my surprise, I loved it! It
was a friendly club, and in my first year most of us were beginners. I used to go two or
three times a week to train. Because it is not a team sport, I didn't feel guilty (内疚
的) about not being very good.And because it is a combat (格斗) sport, you train
in pairs, which means that you get to meet people and talk to them. When I was doing kung
fu, I got stronger and quicker. Unluckily, in the last year of university I was too busy
to do kung fu most of the time.
When I moved to Italy this year I decided to start doing a combat sport
again. I found a great local club that does mixed martial arts (综合格斗) and I
love it. The club is more serious than the one at my university and we do lots
of practice fights. It is very fun.
When I was a teenager, I would say I just wasn't a sporty person and that I just
didn't like sport and never would.Now I know that everyone should try as many sports as
possible because there is often something out there for everyone!

Lise Meitner was born in Vienna, Austria on November 7, 1878. She was the third
child of eight children in the family. Her father Philipp, who was a lawyer, hired
personal teachers to teach the children, and she learned mathematics very well. Music
was important to the family, and all the children learned to play the piano. The Meitner
children were taught to listen to their parents, but to think for themselves.
When Lise Meitner finished school at the age of 14, she could not go to college for
higher education, as were all girls in Austria.But, inspired by the discovery of Henri
Becquerel, she was determined to study radioactivity (放射性).
When she turned 21, women were finally allowed into Austrian
universities.Meitner was admitted into the University of Vienna; there she was
excellent at math and physics and earned her doctor's degree in 1906. She wrote
to Marie Curie, but there was no room for her in the Paris lab, so Meitner made her way
to Berlin. There she worked with Otto Hahn, but as an Austrian Jewish woman, she was
excluded from the main labs and allowed to work only in the basement.
In 1912, the pair moved to a new university and Meitner had better lab equipment.
Though Meitner was forced to escape Nazi Germany in 1938, they continued to co-
work. Meitner continued her work in Sweden and later they found the phenomenon “nuclear
fission (核裂变)”. The discovery, which finally led to the atomic bomb, won Hahn the
Nobel Prize in 1944. Meitner, ignored by the Nobel committee (委员会), refused to
return to Germany after the war and continued her atomic research in Stockholm into her
80s.

personal teachers to teach the children, and she learned mathematics very well. Music
was important to the family, and all the children learned to play the piano”可知,Lise
Meitner小时候接受了良好的教育。]
13.Why didn't Lise Meitner go to college after finishing high school?
A.She wasn't interested in college.
B.Girls in her country were not allowed.
C.Her family couldn't afford the school fees.
D.She wanted to study radioactivity by herself.
B [细节理解题。根据第二段中的“When Lise Meitner finished school at the age
of 14, she could not go to college for higher education, as were all girls in Austria”及
第三段第一句可知,Lise Meitner高中毕业后没能上大学是因为当时在奥地利女孩不允许上
大学。]
14.What did Lise Meitner probably realize when working in Berlin?
A.She was unfairly treated there.
B.She made the wrong college choice.
C.She should have kept her identity a secret.

故,她被不公平地对待。]
15 . What was most probably Lise Meitner's attitude toward the Nobel
committee?
A.Indifferent. B.Unclear.
C.Angry. D.Supportive.
C [推理判断题。根据最后一段中的“Meitner,ignored by the Nobel committee(委员

Communication Tips
Here are some suggestions about making your talk with your parents turn out for the
best.
更多资料添加微信号:hiknow_007 淘宝搜索店铺:乐知课堂Be honest.
If you're always honest, your parents will be likely to believe what you say. If
you sometimes hide the truth, parents will have a harder time to believe what you tell
them. 16
Be brave and start talking.
It's easy to say “Hi, Mum” or “Dad, can you pass the potatoes?” 17 Let's face
it. You will feel embarrassed (尴尬的)when talking about something personal, but
your parents know you quite well.They were your age once, too! So don't let a
little embarrassment stop you. It's OK to go ahead and share what's on your
mind.
18
If you have a disagreement, can you consider things from your parents' points of
view? If you can, telling your parents you understand their views and feelings
helps them be willing to understand yours, too.
Try not to argue.
Using a friendly and respectful tone makes your parents more likely to listen to
you and take what you say seriously. 19
What if it doesn't work? If you still can't talk to your parents, seek other
adults' help. 20 Then follow all the tips above to make you communicate with
that person well.
A.Explain your situation.
B.Try to understand them.
C.If you lie, they'll find it hard to trust you.
D.Parents are the most important people in your life.
E.But it can be harder to start talking about personal topics.
F.It also makes it more likely that they'll talk to you in the same way.
G.Find a relative or a teacher who will listen to, understand and care about you.
【语篇解读】 本文是说明文。文章提出了几个与父母更好的沟通的方法。
16.C [本段主旨为要诚实,C项“如果你说谎,他们将很难信任你”与该段主旨吻合,
而且三个“If”句,表示状况逐步变糟。]
17.E [从空白后的face it可知,后面面临的是较难的问题,正好与前面的easy构
成转折关系。由此推知,该处为过渡句,E项“但是,讨论个人问题会较难开口”符合逻辑。]
18.B [本段主要讲如果你与父母之间有分歧时,你要从他们的角度考虑问题,这样他
们也会愿意去理解你的想法,B项“试图去理解他们”与本段主要内容吻合,总领该段。]
19.F [空白处前提到不要争吵,要用友好和尊重的语气和父母交流,因为这样也更可
能会让你的父母以同样的方式与你交流,F项中的“It”指代空前句子。]
20.G [根据空白处前句子“如果你仍然不能和父母交流,那就寻求其他成年人的帮助”,
更多资料添加微信号:hiknow_007 淘宝搜索店铺:乐知课堂由此可知,空白处填“找一个倾听你、理解你、关心你的亲戚或老师”符合语境。]

Even though my grandfather was a farmer, my grandmother would iron(熨烫) his work
clothes every day. She would sprinkle (喷洒) grandpa's 21 with something,
hang them over a chair so they could dry a bit, and then iron them. I 22 her do
this through my childhood.I thought every old woman in the world did it. But as
the years passed, I began to 23 this practice.Why did grandfather need his work
clothes 24 ? Most days, he never met anyone but me and a few other farmers.
One day I asked grandma about it. She told me that grandpa was the most 25 man
in the world, and he was the 26 of her life.
Later that day, I looked closely at grandpa.He sure didn't look all that
handsome to me.He was a short and skinny man. His hair was 27 on top,and
his false teeth didn't line up very well when he smiled.So I 28 grandma about it
again. I informed her I had observed grandpa.She 29 and said, “You just
aren't viewing things from the right perspective (角度). Those eye wrinkles haven't
always been there.He has beautiful blue eyes.” She 30 , “I want him to feel
beautiful. I iron his clothes every day 31 he has made me feel beautiful for
all these years. He is a man worthy of 32 .” I heard what she said and was
still puzzled.How could this old woman think that an old man with false 33
was beautiful?
The years went on, and I watched grandma and grandpa grow old together. I 34
knew what beauty really was—it was grandma ironing grandpa's pants. I was
ashamed and decided to 35 the question I had asked.

更多资料添加微信号:hiknow_007 淘宝搜索店铺:乐知课堂One day my dad came back home in his truck and there was a cage in the back.
Naturally I was curious, so I went towards the truck when I noticed that there was a
small little goat that wasn't even an adult yet.
I asked my dad and he said that he bought the goat from his friend and he was going to
kill it twenty minutes after he brought it home so that we would have a big meal.
My sister was there too and she was strongly for my view. We found out we got
really mad at my dad and told him not to kill it. After about 10 minutes of
complaining we finally convinced my dad not to kill it because we told him that
there was no reason for him to kill the goat himself when he could just buy goat
meat at a store.
My parents know some friends that we visit sometimes and their family really likes
animals so we decided to give it to them. For about a month, they had the goat as a pet and
they also had the same problems as we had because the dad wanted to kill it and eat it
but the rest of the family didn't want it to die.They also were able to persuade
him not to do so. They ended up sending the goat to a family member's farm where
it would grow up happily.
Another thing that has happened to influence my belief is that I have a
neighbor that really likes hunting. One day he hunted a deer and brought the
body home, but he decided to leave it outside his house for everyone to see. He just
left it there as if it were some kind of award that he just won. Sadly little kids
started to make fun of the body and pretended to ride on it. They laughed at it
and felt no problem with there being a dead deer just laying.
Paragraph 1:
I felt sick by what was happening and left because of what I had just
witnessed.___________________________________________________________
_________________________________________________________________
_________________________________________________________________
Paragraph 2:
It amazes me how we have changed from hunting to survive to hunting for
sport._______________________________________________________________
_________________________________________________________________
_________________________________________________________________
【参考答案】
Paragraph 1:
I felt sick by what was happening and left because of what I had just witnessed.The
majority of the people there saw no problem with what was happening. They didn't
think they were doing wrong and that they were to blame for that. A month
later, I found out that my neighbors' daughter wanted to hunt when she got older
更多资料添加微信号:hiknow_007 淘宝搜索店铺:乐知课堂because she thought it was “fun”, which bothered me greatly.
Paragraph 2:
It amazes me how we have changed from hunting to survive to hunting for sport. I
just don't think there is any reason to kill a living thing for fun. This just leads
people to hunt animals.And even the small little goat is endangered because people
start to think that there's nothing wrong with killing a life as long as it's
not a human. If there's one thing I beg you to do, it's to be openminded towards
animals not just to humans and don't kill for sport.
