null Unit 3: Security Text A: The Land of Lock Part I:Introduction of Author Part I:Introduction of Author Bob Greene is a Chicago Tribune columnist for whom life appears to have peaked at a 1964 Jan and Dean concert in his native Columbus, Ohio.null Greene's frequent ink-stained trips to the past tell us that though we've gained much as time has marched forward, we have lost much as well. We have lost, as Greene emphasizes, our inability to escape the technology that aids us. This test “The Land of The Lock” is just a good example of his works.

Various kinds of security devices: 1) Dead-bolt locks, security chains, electro-nic alarm systems and trip wires are widely in use. 2) Suburban families have steel bars built in sliding glass doors. 3) Small notices warning against burglary are commonly seen pasted on the windows of the most pleasant homes. null4) Access cards are required of those who work with medium- to large-size companies. 5) Airport security uses electronic X-ray equipment to guard against terrorism. 6) Businessmen use new machines linked up to their telephones to help detect whether the caller is telling lies or not. 7) Suburban housewives wear rape whistles on their key chains.nullIII. Features of Writing in the text 1. When we read, we are not only learning new vocabulary or structure, but also looking for key information. Identifying keywords is even more important if our reading time is not that plentiful. “Lock” is the keyword in this text, by locating “lock’s” throughout the text, we get a pretty good idea of what this essay is about.null2. There are several examples of comparison and contrast in this article: Para l vs. Para 4, Para l0 vs. Para 1l, Para l2 vs. Para 13. The first pair acts as the opening of the whole piece of writing. The latter two are just two supporting details for the central argument. 3. Other devices: It is interesting to see how the author threads his narration back and forth between the past and present. Never for once he does write “in the past” or “at present” explicitly. null The writer has still cleverer devices at hand, like a subtle tense change (e.g. simple past in Para. 1 vs. present perfect in Para. 4), a phrase that indicate an old habit in contrast with a phrase indicating the current state (i.e. “used to” vs. “no longer” in Para. 11), or a summary sentence ( It wasn’t always like that” in Para.12).null1. on the latch: (of a door) closed but not locked --Don’t forget to leave the front door on the latch if you go to bed before I come back. 2. close up: shut sth. esp. temporarily --I want so much to close up my store and go traveling for a couple of months. --On the New Year’s Eve the stores in the town are all closed up. c.f.

Your composition should be no less than 150 words.  Should Violence Be Forbidden On the Screen? nullIt is common sense /Common sense tells us that strong lightening is a barrier to criminal activities. A light should be fixed in the doorway and switched/kept on at night. Believe it or not, some people, particularly children, who happened to be the last to enter the house, leave the door on the latch at night. Even locked, doors of hollow core are vulnerable to break-ins. Thus doors of solid core or steel are preferred as they are more difficult for burglars to pry open. If you decide to buy an alarm device, remember to ask for signs for it and stick them/nullput them up both on the doors and on the windows. Finally, a word of warning---when you travel, make (it) sure that you ask a trusted neighbor to collect the newspapers and mail at the gate/door everyday before you come back home.This is because a collection of newspapers and mail at the doorstep or in the mailbox is an advertisement telling the burglars that you are not at home/the house is empty.
