科学家做了下面的实验：把家蝇分成多组，每组分为A，B两部分，用DDT处理每组的A

The world would be a very different place if someone hadn’t invented the lift. There would be few, if any, high-rise buildings because people would refuse to climb many stairs. By the time workers reached their offices on the top floors of a tower building, it would be time to go home – if they were not too tired for the long walk down！

The first lift that we know about was used by the Greek scientist, Archimedes, in about 230 BC. It was a simple place that could be pulled up and down with a rope. A lift like this was used much later in the 12^th century by priests who lived on top of a mountain at Metereo in Greece. Because they were afraid of killers, the priests had not built any stairs up the mountain. The only way up was by lift, which priests worked from the top of the mountain.

A few hundred years later, a Frenchman, Villayer, invented a ‘flying chair’ which used a rope and a place. A number of rich people had these ‘flying chairs’ built in their homes, including Queen Anne of England in Windsor Castle and Louis XVI of France at Versailles. Unluckily, Louis’ daughter was badly hurt when using one of the chairs, and Villayer ran away, afraid that he would be punished.

The main problem for lift engineers was that either humans or animals were needed to pull the ropes. This problem was not worked out until the discovery of steam power. But even steam powered lifts were not always safe because they also used ropes which sometimes broke. If the rope broke - which it sometimes did - the lift fell to the ground and people in it were killed or hurt. This problem worked out in 1854 when an American, Elisha Otis, invented something which stopped the lift from falling if the rope broke. At first Otis lifts were used only in factories, then in 1857 he built one in a large New York store. Now lifts use electric power and are completely safe. They also travel very quickly. Some lifts travel faster than 60 kilometers an hour.

唐故秘书少监陈公行状

公姓陈氏，自颍川来，讳京。(大历元年)举进士，为太子正字、成阳尉、太常博士、秘书少监。自考功以来，凡四命为集贤学士。德宗登遐①，公病痼，舆曳就位，备哀敬之节，由是滋甚，遂以所居官致仕。贞元二十一年四月二十五日，终于安邑里妻党之室。无子。

大历中，公始来京师，中书常舍人衮，杨舍人炎读其文，惊以相视曰：“子云之徒也。”常以兄之子妻公，由是名闻。游太原，太原尹喜曰：“重客至矣。”授馆致饩，厚以泉布献焉。公曰：“非是为也，某尝为《北都赋》未就，愿即而就焉。其宫室城郭之大，河山之富，关闬之壮，与其土疆之所出，风欲之所安，王业之所兴，苟得闻而睹之足矣。若曰受大利，是以利来，盖异前志也。吾不能，敢辞。”遂逆大河，逾北山，仿佯而归。《赋》成，果传天下。为咸阳尉，留府廷，主文章，决大事。

泾人作难，公徒行以出，奔问官守。段忠烈之死，上议罢朝七日②。宰相曰：“不可，方居行宫，无以安天下。”公进曰：“是非宰相之言。天子褒大节，哀大臣，天下所以安也，况其特异者乎?”上用之。

巡狩所至，上行罪己之道焉，曰：“凡我执事之臣，无所任罪。予惟不谨于理而有是也。”将复前之为相者。公曰：“天子加惠群臣而引慝③焉，德至厚也，而为相者复，是无以大警于后，且示天下。”率其党争之。上变于色，在列者成凶而退。公大呼曰：“赵需等勿退!”遂进而尽其辞焉。不果复。

初礼部试士，有与亲戚者，则附于考功，莫不阴授其旨意而为进退者。及公则否，卓然有有司之道，不可犯也。

公有文章若干卷，深茂古老，慕司马相如、扬雄之辞，而其诂训多《尚书》《尔雅》之说，纪事朴实，不苟悦于人，世得以传其稿。

注：①登遐：特指帝王之死。②建中四年十月，泾原节度使姚令言反，犯京师。戊申，德宗幸奉天。庚戌，朱此杀司农卿段秀实。③引慝：承认罪过。

B．陈京曾经游太原，太原百姓非常高兴，他们对他进行了丰厚的馈赠。陈京表示，他不是为这而来的，主要是为了完成《北都赋》，因此没有接受礼物。而他的《北都赋》写成后，果然天下传扬。

C．忠烈公段秀实牺牲，皇上建议罢朝七天，宰相坚决反对。陈京严厉驳斥了宰相的说法，高度肯定了皇上的做法。最后皇上采纳了他的意见。
