[不定项选择题]共用题干 Brotherly Love

Adidas and Puma have been two of the biggest names in sports shoe manufacturing for over half a century.
Since 1928 they have supplied shoes for Olympic athletes,World Cup-winning football heroes,Muhammad
Ali,hip hop stars and rock musicians famous all over the world.But the story of these two companies begins
in one house in the town of Herzogenaurach,Germany.
Adolph and Rudolph Dassler were the sons of a shoemaker. They loved sports but complained that they
could never find comfortable shoes to play in.Rudolph always said,"You cannot play sports wearing shoes
that you'd walk around town with."So they started making their own.In 1920 Adolph made the first pair of
athletic shoes with spikes(钉),produced on the Dasslers'kitchen table.
On 1 st July 1924 they formed a shoe company,Dassler Brothers Ltd and they worked together for many
years.The company became successful and it provided the shoes for Germany's athletes at the 1928 and
1932 Olympic Games.
But in 1948 the brothers argued.No one knows exactly what happened,but family members have sug-
gested that the argument was about money or women.The result was that Adolph left the company.His nick-
name was Adi,and using this and the first three letters of the family name,Dassler,he founded Adidas.
Rudolph relocated across the River Aurach and founded his own company,too.At first he wanted to
call it Ruda,but eventually he called it Puma,after the wild cat.The famous Puma logo of the jumping cat
has hardly changed since.
After the big split of 1948 Adolph and Rudolph never spoke to each other again and their companies
have now been in competition for over sixty years.Both companies were for many years the market leaders,
though Adidas has always been more successful than Puma. A hip hop group,Run DMC,has even written a
song called"My Adidas"and in 2005 Adidas bought Reebok,another big sports shoe company.
The terrible family argument should really be forgotten,but ever since it happened,over sixty years
ago ,the town has been split into two.Even now,some Adidas employees and Puma employees don't talk to
each other. The brothers argued about the shoes.

[简答题]结渣对锅炉的安全经济运行会造成哪些危害?
[单项选择]Passage Four “Family” is of course an elastic word.But when British people say that their society is based on family life,they are thinking of “family” in its narrow,peculiarly European sense of mother,father and children living together alone in their own house as an economic and social unit. Thus,every British marriage indicates the beginning of a new and independent family—hence the tremendous importance of marriage in British life. For both the man and the woman,marriage means leaving one`s parents and starting one`s own life.The man`s first duty will then be to his wife,and the wife`s to her husband.He will be entirely responsible for her financial support,and she for the running of the new home.Their children will be their common responsibility and theirs alone.Neither the wife`s parents nor the husband`s,nor their brothers or sisters,aunts or uncles,have any right to interfere with them—they are their own masters. Readers of novels like Jane Austen`s Pride and Pre
