1. 撰写英文摘要(练习题参考答案)
( 1) Abstract: Metropolitan Detroit ( USA) is underlain by unconsolidated sediments of glacial，-lacustrine and fluvial origin. These sediments form a complex series of confined aquifers overlain by an extensive unconfined surficial aquifer. All surface w ater w ithin metropolitan Detroit originates from this complex system of aquifers. Groundw ater w ithin the near-surface unconfined aquifer discharges directly into the Rouge River，the dominant river in the metropolitan area. The Rouge River is a major tributary to the Detroit River，w hich empties into Lake Erie. Thousands of sites of environmental contamination are located w ithin metropolitan Detroit. The combination of contaminated sites and near-surface groundw ater that flow s and discharges into the Rouge River creates a significant potential for contamination to eventually migrate to the Great Lakes. The Rouge River is currently identified as an area of concern by the International Joint Commission ( IJC ) and represents a significant source of pollution to the Great Lakes. Key words: Near-surface aquifer; glacial deposits; urban environment; groundwater; environmental contamination
( 2) Abstract: The ability of sea water to flow into coastal or submarine cavities is surprising，in view of the fact that sea level is，for w ater，a level of minimum gravitational potential w here it can perform no w ork. To achieve a low er potential requires energy，the provision of w hich is an example of a completely original aspect of the interaction betw een subterranean hydrodynamics and marine hydraulics. We have studied a spectacular example of the simultaneous outflow of fresh w ater and inflow of salt w ater at a karstic spring running into a salt-w ater lagoon on the French Mediterranean coast，and w e suggest here a hypothesis to account for the surprising double-layered，tw o-directional flow observed. Key words: Limestone aquifer; karstic spring; salt water; fresh water; simultaneous flow
( 3) Abstract: In north-central Oregon a large area of near-zero near-surface conctive heat flow occurs in young volcanic rocks of the Cascade Rage. Recent advective heat flux measurements and a heat-budget analysis suggest that groundw ater circulation sw eeps sufficient heat out of areas w here rocks younger than 6 Ma ( million years ago) are exposed to account for the anomalously high advective and conctive heat discharge measured in older rocks at low er elevations. Earlier w orkers have proposed that an extensive midcrustal magmatic heat source is responsible for this anomalously high heat flow. Instead，high heat flow in the older rocks may be a relatively shallow phenomenon caused by regional groundw ater flow. Any deeper anomaly may be relatively narrow ，spatially variable，and essentially confined to the Quaternary ( less than 2 Ma) arc. Magmatic intrusion at a rate of 9 to 33 cubic kilometers per kilometer of arc length per million years can account for the total heat flow anomaly. Deep drilling in the areas of high heat flow in the older rocks could indicate w hich model is more appropriate for the near- surface heat flow data. Key words: Conctive heat flow ; water circulation; hot spring; thermal groundwater; magmatic intrusion
( 4) Abstract: Fresh water aquifers in small coral islands usually occur as thin lenses w hich are significantly influenced by stresses such as groundw ater pumping，sea tides，etc. Kavaratti，a coral island，is one of the 36 such islands in the Arabian Sea off the w estern coast of India. Detailed hydrogeological investigations w ere carried out to determine the quantity of fresh w ater that could be pumped in addition to the present usage. Salinity of groundw ater must remain w ithin permissible limits and a 2-D solute mass transport model w ith a vertical section of the island w as constructed by the computer code SUTRA. The model w as calibrated by obtaining a match of computed and observed values of the w ater table，tidal efficiency，and salinity of groundw ater at the w ater table. The model analysis show ed that the salinity of groundw ater continues to increase unless groundw ater pumping is kept below a certain rate. Groundw ater potential can be augmented by recing the subsurface outflow to the sea and by raising the w ater table by a subsurface dam.
Key words: Island; water table; tidal effect; abstraction; sea water intrusion

根据课文第8行Officials from Greenwich Observatory have the clock checked twice a day 可以判断只有d与课文事实相符,其他3个选择都与事实不符.
课文中用的是have sth.done 的形式，那么就是说是official让别人来检查clock, 但是检查clock 的也可以是official啊, 某个official让另外一个人去检查,这个人不是他本人,是另外的officail 也是可以的啊.
3. b
本句前半句陈述的是一个公认的事实，后半句则表示一个经常性或习惯性的动作，应该用一般现在时才符合逻辑，即“每当你到伦敦的时候”。a. will visit c. have visited , d. will be visiting 这3个选择时态都不对，只有b. visit 是一般现在时，最符合语法，所以应该选b.
4. b
只有选b. 最符合题目意思，符合语法。 a. famousest 不是正确的最高级形式，famous 的最高级应该是the most famous; c. the more famous:比较级前不应该有定冠词，另外本句也没有表示比较的连词than; d. famouser 不是正确的比较级形式。
5. c
本句若选a. and, b. also, d. together都不合乎语法,也不符合题目意思,只有选c. both才合乎语法,意思通顺.所以选c.

9. b
只有b. ty(责任,职责)才能同前一句意义相同. a. responsible(负责的)虽然词意思正确,但词性不对,应该是名词才适合这个句子.c. charge(责任,职责)虽然词义和词性都正确,但一般不用在这类句子中,而常用在词组中,如in charge of , take the charge of等, d. control(控制,支配)不符合题目意思.
10. c

d. how long 是对长度提问的,
所以应该选d
5. b
a. It was difficulty for him 和c. It was difficulty 都有语法错误，应该用形容词difficult 作表语才对；d. He was difficult 也不对，因为本句的主语是后面的动词不定式，所以前面应该用it做形式主语才对； 只有b. It was difficult for him 最合乎语法，所以选b.
