2 阅读下面材料，回答问题。（7分）北京师范大学某教授认为，汉语的危机，并不是普通话的危机，而是另外两个危机：一是方言的流失。上世纪80年代他初到北京时，经常听到“劳驾”、“借光”、“盖帽儿”之类的词，现在几乎听不到了，很多原先挂在人们口头上的方言都消失了。二是古汉语的流失。他认为，年轻人的古汉语阅读和使用能力在普遍下降。对于方言流失与古汉语流失的危机，你有什么看法？请简要阐述。（要求：表达简明连贯，言之成理，150字左右。）

4 阅读资料，回答下题。当低纬地区海水表面温度超过27.5℃的时候，空气的扰动（如局部雷电等）就会导致热带气旋在该类海域诞生。热带气旋在低纬海区移动过程中，可能逐步加强，发育成强热带风暴，直到台风、强台风。它们到达人类活动的海域以及滨海地带形成灾害性天气，对人类生命财产造成巨大危害。有人设想：对热带气旋经过的海面进行人为干预来限制其加强的过程，降低台风、强台风形成的几率，减轻此类灾害性天气带来的危害。（1）试说明热带气旋在移动过程中加强的大体过程。 ___________________________________________________________________________________________ ___________________________________________________________________________________________ （2）扼要阐述人为干预海面限制热带气旋加强过程的基本原理。 ___________________________________________________________________________________________ ___________________________________________________________________________________________ （3）简述你对这种设想可行性的看法。 ___________________________________________________________________________________________ ___________________________________________________________________________________________

7 The history of English Coins English coins have developed and changed over time. In the early 1600s" coins were made using the hammer struck method. Hammered coins or cast coins where the primary way coins were made and thus limited the number of coins that may be placed into circulation (流通). Hammered coins were made as far back as the first millennium BC with continued in use until the 1500s to the 1700s. English coins underwent a change in about 1663. Hammered English coins were made using a blank quantity of metal that was the required weight and placing it between two dies. A die is a mold (模子) that allows the metal to get cut to a certain size and shape.The metal die contained an image that when hammered without delay would mold the image on each side of the coin. The unit was customarily place on a log or other firm surface which was known as a pile. One person held the die while a second person struck it. There were several issues with this kind of coin making. For one thing, it was extremely slow and work in depth. Comparatively few coins might be made and placed into circulation. A second problem was that hammered coins had many irregularities. When several coins were placed together in a container and shaken about they were damaged as well. That is why older English coins might have chips(缺口) and rough edges. During the 17th century hammered coins were replaced with milled (轧有花边的) coins. While France was the first country to start producing coins that were made entirely by machine, Britain wasn"t far behind. Britain, in fact, began to manufacture coins on a trial basis in the mid1500s, but it wasn"t until the end of 1662 that English coins were made completely by machine. The screw press (螺旋压力机) was the first machine to produce coins as an alternative to hammered coins. Leonardo da Vinci was the person who invented the screw press in the 15th century. It was powered by a water mill. Early on efforts were made to protect the coins by edging. You"ll see that Englishmade coins have milled edges. Milled English coins were much more standard in size and shape as well. The speed at which milled coins could be created allowed the coin circulation to grow and a greater number of coin types to be developed. English coins were used in this country during the royally period. Hammered coins were produced and used up through the end of the 18th century and were given out across the colonies. English coins went through quite a lot of changes as can be seen in old coins that have been started in the US over time. __小题1:__of English coins Time & Major Events Hammered coins ◆The hammer struck method used to make coins has a history dating back to the first millennium BC. ◆At least two people are needed to carry out the work, with one _小题2:__the die and the other striking it. ◆__小题3:_： ◆The number of coins made and placed into circulation this way was _小题4:__. ◆Older English coins were quite __小题5:_，with many having chips and rough edges. ◆Such coins were placed into circulation across the colonies and __小题6:_ in use through the end of the 18th century.
