Dear Mr Lee
Subject: Faulty HP 5590 Scanners
Three months ago, our training center bought 10 HP 5590 scanners from your company --- see our order number G868281. Until (1), these scanners worked properly. (2 ), we have started to notice that fuzzy image is becoming increasingly common with these scanners.(3) , this is a problem with this model that appears only after a few months' service. This is not satisfactory.
This matter is causing us great (4), since we need to scan a lot of documents every day. We should,(5 ), like you to replace all of the machines that we bought, with your newer model HP 5591 scanners,(6) , we understand, do not have the same design fault.
(7)you know, we do a lot of business with your company, and we have always (8) pleased with your service. It would be a great (9)if this good relationship is spoiled.
I look forward to (10)your reply soon.
Yours sincerely

The Turing machine is an abstract(71)of computer execution and storage introduced in 1936 by Alan Turing to give a mathematically precise definition of(72). or 'mechanical procedure'. As such it is still widely used in theoretical computer science, especially in(73)theory and the theory of computation. The thesis that states that Turing machines indeed capture the informal notion of effective or mechanical method in logic and mathematics is known as Turing's thesis.
Every Turing machine computes a certain(74)partial function over the strings over its alphabet. In that sense it behaves like a computer with a fixed program. However, as Alan luring already described, we can encode the action table of every Turing machine in a string. Thus we might try to construct a Turing machine that expects on its tape a string describing an action table followed by a string describing the input tape, and then computes the tape that the encoded Turing machine would have computed. As Turing showed, such a luring machine is indeed possible and since it is able to simulate any other Turing machine it is called a(75)Turing machine.
A universal Turing machine is Turing complete. It can calculate any recursive function, decide any recursive language, and accept any recursively enumerable language. According to the Church-Turing thesis, the problems solvable by a universal Turing machine are exactly those problems solvable by an algorithm or an effective method of computation, for any reasonable definition of those terms.

I learnt very soon in our relationship that Kathy was jealous. She did not like to think that I had anything that she did not have. We would have great fun going out shopping. However, if I bought, say, a dress for a party, and she thought my dress was better than hers, she would start to say slightly unkind things about it. I could not understand this at all, and even now it puzzles me.
The other problem was my mother. She thought Kathy was common. She thought Kathy had a bad influence over me. She even disliked Kathy’s way of speaking. She thought her pronunciation was common. Mum disliked Katy and looked down on her and kept telling me to stop seeing her. If ever I invited her into the house, she would be angry and tell me off as soon as Kathy was gone.
