But your son is entering college, and he is willing to become a doctor. Which one do you give the money to for medical school? I've asked this question of everyone from the president of a famous university to an ordinary young soldier, and it has never failed to get a discussion going.

When a person is curious about something, it means he is interested in it and wishes to know something about it. There is &&16& &wrong with curiosity in itself. Whether it is good or bad &&17 &on what people are curious about.
&& Curiosity &18 &can be foolish or wrong. Some people with nothing to do are &19 &of curiosity about what their neighbors are doing. They have a strong wish to know what they are &&20 &home or taking outside, or why they have come home so &21& or late. To be interested in these things is silly because it is none of their 22& &to know what their neighbors do or are doing. Such curiosity is not only foolish but also 23& . For most probably, it may lead to a small talk &24 &often brings harm, loss of honor or disrespect to others, and thus &25& their feelings.
& On the other hand, there is a &26& curiosity- the curiosity of wise men, who &27 &at all the great things and try to find out all they &28& learn about them. Columbus could &29& have found America if he had not been &30 . James Walt would not have made the steam engine &31& &his curiosity about the rising of the kettle lid. All the &32 &in human history have been made as a &33 &of curiosity, 34& &the clever curiosity is never about unimportant things which have &35 &or nothing to do with the happiness of the public.

It was Monday. Mrs. Smith's dog was hungry, but there was not any meat in the house.　　Considering that there was no better way.

entering college, and he is willing to become a doctor. Which one do you give

题型：阅读理解
We have proof that you become what you eat. When you
know the effects of different types of food, you can use your knowledge well
and eat what you want to become.
Food has an impact on our physical and mental health.
Have you ever heard any of the following advice?
Lettuce (莴苣) or milk
can make you sleepy.
To stop feeling sleepy you should eat peanuts or dried
fish.
Everyone has their own advice to give, which they have
read about or have been told by older relatives. Some of these pieces of advice
seem to contradict each other.
Eating chocolate makes you fat and gives you spots.
Chocolate contains the essential minerals: iron and
magnesium (镁).
What we need to figure out is what type of chocolate
to eat to get the benefits and how much of it to eat. We can do this by reading
the list of ingredients (原料) on the chocolate bar package. Exactly how
much real chocolate is in there? And how much of that do we need to eat to get
the benefits of the minerals it contains?
Future restaurants might be named after the physical
or mental state they hope to create. Their menus will list the benefits of each
dish and drink. Some restaurants have already started this concept, and list
the nutritional (营养的) content of their dishes on the menus.
Let’s take the restaurant “Winners” as an example.
Their menu would list dishes specifically designed to help you win sports
competitions. Or you could choose the Go-faster salad, which is a large bowl of
mixed raw vegetables in a light salad dressing, giving you energy without
making you gain weight. And what kind of dishes do you think would be on the
menu at the “Clever Café”?
So what’s going to happen to hamburgers and biscuits?
Will the concept of eating food, because it’s tasty, go out of fashion? Of
course not! Junk food is also changing. If ice-cream is not good for children,
can’t we give them fat-free, sugar-free tofu ice-cream? Unhealthy food is going
out of fashion, so brands are changing. We are told not to drink cola because
of the sugar and caffeine content so cola companies are making sugar-free and
caffeine-free drinks. We are told dried fruit is a healthier snack than
biscuits so some biscuit companies are making biscuits with added vitamins.
1.By saying “you become what you eat”, the writer
means that ________.
A．you will
become your own food
B．you will know
what food is good by its appearance
C．food has an
effect on your health
D．you will know
the effects of different types of food
2.What does the underlined word “contradict” mean in
the text?
A．Oppose to&&&&&&&&&&&&&&&&&&&&&&&&&&&& B．Help with
C．Have
influence on&&&&&&&&&&&&&&&&&&&&&& D．Benefit from
3.How can we eat chocolate properly, according to the
passage?
A．To eat
chocolate containing the essential minerals.
B．To read the
list of ingredients on the package.
C．To get advice
from others before eating real chocolate.
D．To learn how
much chocolate we can consume before eating.
4.Which is true about the future restaurants?
A．The food in “Winners” can ensure
you to win sports competitions.
B．They might
list the nutritional content of their dishes on the menus.
C．Hamburgers
will disappear in these restaurants.
D．The Go-faster
salad helps you go faster.
5.The concept of eating tasty food will not go out of
fashion because ________.
A．the junk food
companies are changing their brand names
B．biscuit
companies are making dried fruit
C．junk food
will become healthier than before
D．Cola
companies are still making cola

You are playing the following Nim Game with your friend: There is a heap of stones on the table, each time one of you take turns to remove 1 to 3 stones. The one who removes the last stone will be the winner. You will take the first turn to remove the stones.
Both of you are very clever and have optimal strategies for the game. Write a function to determine whether you can win the game given the number of stones in the heap.
For example, if there are 4 stones in the heap, then you will never win the game: no matter 1, 2, or 3 stones you remove, the last stone will always be removed by your friend.
博弈论中极为经典的尼姆游戏。有总数为n的石头，每个人可以拿1~m个石头，两个人交替拿，拿到最后一个的人获胜。究竟是先手有利，还是后手有利？
1个石子，先手全部拿走；2个石子，先手全部拿走；3个石子，先手全部拿走；4个石子，后手面对的是先手的第1，2，3情况，后手必胜；5个石子，先手拿走1个让后手面对第4种情况，后手必败；6个石子，先手拿走2个让后手面对第4种情况，后手必败；&& 容易看出来，只有当出现了4的倍数，先手无可奈何，其余情况先手都可以获胜。 （石子数量为4的倍数）后手的获胜策略十分简单，每次取石子的数量，与上一次先手取石子的数量和为4即可； （石子数量不为4的倍数）先手的获胜策略也十分简单，每次都令取之后剩余的石子数量为4的倍数（4*0=0，直接拿光），他就处于后手的位置上，利用上一行的策略获胜。
代码极为简单：

if(n % 4 == 0)
