托福官方真题Official24阅读长难句官方真题Official24: Lake Water

1. Then exchanges with the atmosphere are calculated by finding the difference between the  gains from rain, as measured (rather roughly) by rain gauges, and the losses by evaporation, measured with models that correctfor the other sources of water loss.

2. Changes in lake level not explained by river flows plus exchanges with the atmosphere must be due to the net difference between what seeps into the lake from the groundwater7 and what leaks into the groundwater.

3. The residence time is an average; the time spent in the lake by a given molecule (if we could  follow its fate) would depend on the route it took: it might flow through as part of the fastest, most direct current, or it might circle in a backwater for an indefinitely long time.

4. In the period 1970 to 1986, rainfall in the area decreased from 1,000 millimeters to 650  millimeters per annum, while above-average temperatures speeded up the evapotranspiration rate (the rate at which water is lost to the atmosphere through evaporation and the processes of plant life).

官方真题Official24: Breathing During Sleep

1. During NREM (the phase of sleep in which there is no rapid eye movement) breathing becomes deeper and more regular, but there is also a decrease in the breathing rate, resulting in less air being exchanged overall.

2. The amount of air exchanged is even lower in REM than NREM because, although breathing is more rapid in REM,it is also more irregular, with brief episodes of shallow breathing or absence of breathing.

托福官方真题Official24阅读长难句官方真题Official24: Moving Into Pueblos

1. In the Mesa Verde area of the ancient North American Southwest, living patterns changed in the thirteenth century, with large numbers of people moving into large communal dwellings called pueblos, often constructed at the edges of canyons, especially on the sides of cliffs.

2. Few of the cultural traditions and rules that today allow us to deal with dense populations existed for these people accustomed to household autonomy and the ability to move around  the landscape almost at will.

3. Some scholars expand on this idea by emphasizing a corresponding need for arable land  to feed growing numbers of people: construction of small dams, reservoirs, terraces, andfield houses indicates that farmers were intensifying their efforts during the 1200s.

4. Archaeologists find that even the most isolated residences during the eleventh and twelfth centuries obtained some pottery, and probably food, from some distance away, while major ceremonial events were opportunities for sharing food and crafts.

5. Scholars believe that this cooperation allowed people to contend with a patchy environment in which precipitation and other resources varied across the landscape: if you produce a lot of food one year, you might trade it for pottery made by a distant ally who is having difficulty with crops—and the next year, the flow of goods might go in the oppositedirection.
