One day I was out fishing with Spot when we heard a lot of shouting in the 38 followed by a scream and splash. I was a bit 39 so I called Spot and we both hid 40 a bush where we could see but not be 41 . After a few moments, a straw hat came drifting down the river, followed by an oar, a picnic basket and 42 oar. Then came the rowing boat itself, but it was 43 upside down ! A few seconds later my Dad and Auntie June came running 44 the river bank, both wet 45 . Spot started barking so I came out of hiding and said hello. My Dad got really angry 46 me for not trying to catch the boat as it went past. Luckily, 47 , the boat and both the oars had been caught by an overhanging tree a little further downstream, but not the hat or picnic basket. So I had to let them 48 my sandwiches. Dad and Auntie June both made me 49 not to tell Mum what had happened 50 she would be worried.

假设娜塔莎的效用函数为给出,式中,I为以千美元为单位的年收入。
(1)娜塔莎是风险偏好型的、风险中性的,还是风险规避型的?请解释。
(2)假设娜塔莎现在的收入为40000美元(I =40),同时明年也肯定可以获得同样的收入。她现在面临另外个工作机会,该一工作获得44000美元收入的概率为0.6,获得33000美元收入的概率为0.4。她会选择这个新工作吗?
(3)在(2)中,娜塔莎为了规避新工作对应的收入的波动,愿意购买保险吗?如果愿意,她愿意支付多少保费? (提示:风险溢价是多少?)
Suppose that Natasha's utility function is given by,where I represents annual income in thousands of dollars.
a. Is Natasha risk loving, risk neutral, or risk averse? Explain.
b. Suppose that Natasha is currently earning an income of $40000 (1 = 40) and can earn that income next year with certainty. She is offered a chance to lake a new job that offers 0. 6 probability of earning S 44000, and 0. 4 probability of earning $ 33000. Should she take the new job?
e. In (b), would Natasha be willing to buy insurance to protect against the variable income associated with the new job? If so, how much would she be willing to pay for that insurance? (Hint:What is the risk premium?)

The summer holidays are the best part of the year for most children.The weather is usually good, so that one can spend most of one’s time playing in the garden or, if one lives in the country, out in the woods and fields.Even if one lives in a big town, one can usually go to a park to play.
The best place for a summer holiday, however, is the seaside.Some children are lucky enough to live near the sea, but for the others who do not, a week or two at one of the big seaside towns is something which they will talk about for the whole of the following year.
In England, it is not only the rich who can take their children to the seaside; if a factory worker or a bus driver, a street cleaner or a waiter wants to take his wife and children to Southend or Margate, Blackpool or Clacton, he is usually quite able to do so.
Now, what is it that children like so much about the seaside? I think it is the sand, sea and sun more than any other things.Of course, there are lots of new things to see, nice things to eat, and exciting things to do, but it is the feeling of sand under one’s feet, of salt water on one’s skin, and of the warm sun on one’s back that makes the seaside what it is.

B.more that two months
C.one and a half months
D.a little less than two months
4.July and August are the brightest months for most children, for they can _______.
A.stay with their parents for all the vacation
B.do more reading
C.play out of doors
D.meet their old friends
5.Children like the seaside so much because they can _______.
