While searching for the origin of personal computer, Shapiro uncovered several computing claims. Stewart Brand, founder of Whole Earth Catalog, says on his Web site that he first referred to a “personal computer” in a 1976 book; and GUI pioneer Alan Kay is said to have used the term in a paper published in 1972.
But a search on JSTOR’s general science archive turned up what Shapiro says is the earliest recorded use of personal computer, in the October 4,1968, issue of Science. The issue contains a Hewlett-Packard advertisement for its new HP 9100A. “The new Hewlett-Packard 9100A personal computer,” the ad says, is “ready, willing and able …to relieve you of waiting to get on the big computer.” The $4900 device---a desktop scientific calculator equipped with magnetic cars---does not seem like much of a computer nowadays. And at 40 pounds, it was not very personal, either. But according to Shapiro, it was the first device to be called a personal computer.
1.The term “personal computer” first appeared().
A.in Byte magazine
B.in a Hewlett-Packard ad in Science
C.in a 1974 book
D.in a paper published by Alan Kay
2.What is JSTOR ？()

A.looking into the Oxford Dictionary
B.digging into magazines that are more than 150 years old
C.scanning JSTOR’s general science archive on line
D.focusing on academic journal such as Science
4.With a HP9100A, according to the Hewlett-Packard ad, you().
A.can easily get on the big computer
B.do not have to get on the big computer
C.can save a lot of money
D.will be willing and ready to do scientific work
5.What do we learn from the passage about the first device that was called personal computer？()
A.It looked very different from the PC today.
B.It was small, light and easy to carry around.
C.It was as efficient as a big computer.

截取一段明文如下:
The Mutual Information Analysis (MIA) is a generic side channel distingui she that has been introduced at CHES 2008. This paper brings three contributions with respect to its applicability to practice. First, we emphasize that the MIA principle can be seen as a toolbox in which different (more or less effective) statistical methods can be plugged in. Doing this, we introduce interesting altematives to the original proposal. Second, we discuss the contexts in which the MIA can lead to successful key recoveries with lower data complexity than classical attacks such as, eg. using Pearson's correlation coefficient. We show that such contexts exist in practically meaningful situations and analyze them statistically. Finally, we study the connections and differences between the MIA and a framework for the analysis of side- channel key recovery published at Eurocrypt 2009. We show that the MIA can be used to compare two leaking devices only if the discrete models used by an adversary to mount an attack perfectly correspond to the physical leakages.

The world I entered at the age of eighteen when I became a medical student was a world that knew nothing of such advanced things as planes, films, radios or telephones. It was a very cheap world. Prices were stable. When I entered St. Thomas' hospital I rent a set of rooms in Vincent Square for which I paid 18 shillings a week. My landlady provided me with a very good breakfast before I went to the hospital and a dinner when I came back at half past six. I only had to pay for the breakfasts and dinners twelve shillings a week. For four-pence I lunched at St. Thomas' on bread and butter and a glass of milk. I could be able to live very well, pay my fees, buy my necessary instruments, clothe myself, and have a lot of fun on fourteen pounds a month. And I could always pawn (当掉) my microscope for three pounds.
I spent five years at St. Thomas' hospital. I was a bad student, for my heart, as you might have guessed, was not in it. I wanted, I had always wanted to be a writer, and in the evenings, after my dinner, I wrote and read. Before long, I wrote a novel called "Liza of Lambeth" , which I sent to a publisher and was accepted. It came out during my last year at the hospital and it was successful. It was of course an accident, but I didn't know that. I felt I could afford to give up medicine and make writing my profession; so, three days after I graduated from the school of medicine, I left for Spain to write another book. I did not realize, at that time, that I was taking a great risk.
The text is a talk given by the author when______.
A．he was 18
B．his first novel was published
C．he graduated from the school of medicine
D．he was at an advanced age
