听力原文： Speaker: Welcome to this presentation on travel opportunities within the
UK. If, like most international students, you want to take some time to travel
around the UK while you are here, there is a lot to see and explore, such as
the capital cities of London, Edinburgh, Cardiff and Belfast; other major cities, Q11
such as Birmingham and Manchester; historic cities, such as Oxford,
Cambridge, York, and Bath; famous natural sites, such as the white cliffs of
Dover in England, the Giant's Causeway in Northern Ireland, Loch Ness in
Scotland and the mountainous scenery in Wales, Scotland, and England's
Lake District and Peak District. There are also hundreds of miles of coastal
paths all around the UK, as well as hundreds of national parks, historical Q12
sites, stately homes and other attractions. Q13
There are also numerous special events and seasonal attractions that
are well worth a visit. In February, for example, look for Chinese New Year
celebrations in London and other cities with large Chinese communities. If
you are thinking of going walking in the Welsh border area, go in late May
or early June and you can also take in the Hay-on-Wye Festival of Literatrue. Q14
Travel to London on the August Bank Holiday to join in the revelry Q15
at the Notting Hill Carnival, a celebration of Caribbean culture. Or head in
the opposite direction, to Edinburgh, in August or September to experience
the superb musical and theatrical performances of the renowned Edinburgh Q16
Festival—and the cutting-edge comedy of the Fringe Festival. Then carry on
up to Braemar in early September to watch the Highland Games: displays of
Scottish Highland dancing and bagpipe-playing together with some very un-
usual and strenuous athletic events.
For further information about the wealth of sights awaiting you in the
UK, search on the Internet, especially www. visitbritain.com, or consult the
travel guides that are available in the library. Also, check with the students'
union to see whether there are any special trips being organised. There is also
a Tourist Information Centre in this city. The address is 13 Wardrock Place. Q17
Now, a few words about getting around. Because the UK is relatively
compact, the national railway network, national coach network and local bus
services link most locations. In addition to the usual range of ticket options, a
variety of special travel passes are available. These can be economical if you
want to do quite a lot of travel within a limited time period—for example,
unlimited coach travel in Wales over an eight-day period. For further information,
see the websites and contact details given on page 5 of the notes you Q18
received as you came in. A word of advice: hitchhiking is legal in the UK, Q19
but it is a risky way to travel and we recommend you avoid it. If you must
hitchhike, then never hitchhike alone—take a friend with you. As a precaution,
leave details of your destination and itinerary with a friend or someone
at your institution.
Now, let's turn to travel accommodation. The following are all fairly
inexpensive places to stay when you are travelling around the UK. First,
there are youth hostels. They are good value for money, although the facilities
can be fairly basic and you usually have to share a room with several
other people. Second, it's worth bearing in mind that university and college
halls of residence rooms are often available to tourists

该管道的管件应采用什么管件？

图8-1所示为某地级市的市域城镇体系规划示意图。该市北部为山区，中部为山前平原，南部为滨海平原。有两条国道呈十字交叉形在市域内通过。
1．该市沿海有N、D、W三个县城。东部海岸为沙质岸线，沙软潮平，水质清澈，附近有海岛；中部主要为礁石海岸，距海岸500m处水深可达20～25m；西部沿海有大面积的盐田。
规划拟在W城布局大型区域电厂(装机容量480万kW)和焦化厂；在D城建深水码头，用进口铁矿石结合当地的煤炭资源，建大型钢铁基地及发展相关的产业；N城拟建盐化工基地。
2．该市市区由三个组团构成，相距均在20km左右。Z组团为中心组团，是全市的政治、经济、文化中心，人口70万。G是以煤炭开采为主的矿区，人口25万。F为新型工业区，是全市的副中心，人口30万。
Z与G、Z与F、Z与N有国道连接，N与D有公路连接。规划还拟分别从Z城、G城建高等级公路与W连接。
3．为保护环境，中心城市各组团都规划建设污水处理厂(见图8-1)。F城与G城之间有一水库，这个水库是城市水源。
指出该规划在工业布局、公路建设及城市基础设施规划中的不合理之处，说明理由并提出改进意见。

据报道，海南某市的吴代市长，在人大召开之前，为了给自己多捞政绩，以求“转正”，于是他头脑一热，强制某汽车制造厂必须在人代会之前生产出第一辆车。在他的强权下，公司按期生产出了汽车，并把汽车用于接山区里来市参加活动的小学生。但是，悲剧发生在途中：由于汽车的制动装置失灵，结果连车带人都翻进了沟里，全车五十多人无一生还。请你就此事谈谈自己的看法。
