Passage 28
2018/4/9
Early life insurers in the United States found themselves facing the problem of obtaining reliable information,as they needed to rely on applicants themselves to provide truthful,complete answers to a standard set of questions.In an attempt to personalize the relationship between insurers and their individual applicants,firms selected highly respected local citizens to act as their agents.These agents were expected to evaluate the appearance of candidates,unearth evidence of unhealthy family histories or questionable habits,and attest to the respectability of the people writing testimonial letters on an applicant's behalf.In short,the initial purpose of the agency system was not to actively solicit customers,but,rather,to recreate the glass-bowl mentality associated with small towns or city neighborhoods.

Passage 68
2018/4/9
Historically,more cold-adapted antelope species originating in Eurasia have migrated into Africa,where the climate is generally warmer,than have warm-adapted African species into Eurasia.A likely explanation for this involves the fact that intercontinental migrations require both a land bridge connecting the two continents and the suitable habitat both on and across that land bridge.During periods of climatic cooling,such as the various ice ages,the land bridge is open for a long time(because sea level remains low)and is usable by cold-adapt species because cool habitats then extend across it.Thus during cooling most migrants would be expected to travel toward Africa,which is near the equator,since this is the direction dictated by habitat changes on a cooling Earth.In contrast,when the Earth is warm,the land bridge is reduced or gone because sea level is relatively high then.Only during the short lag between onset of global temperature change and sea level response can warm-adapted species migrate from the equator toward higher latitudes.

passage 68
2018/4/9
1.
According to the passage,which of the following is true of an Eurasia-Africa land bridge during ice ages?
A.It offers suitable habitats for cold-adapted species of antelope.
B.It encourages migration from Africa to Eurasia of cold-adapted species of antelope.
C.It allows the survival of warm-adapted species of antelope that might otherwise home extinct.
D.It is more likely to exist early in an ice age than later in an ice age.
E.The habitats it offers change more quickly than do those offered by land bridges during other periods.
2.
The author of the passage implies that during the「short lag」,a land bridge between Africa and Eurasia would
A.be inhabited primarily by species of antelope originating in Eurasia
B.be characterized by areas of widely varying elevation above sea level
C.be inhabited by a wide diversity of antelope species
D.contain habitats that could sustain warm-adapt antelope species
E.contain habitats similar to habitats at much higher latitudes in Eurasia
3.
According to the passage,which of the following best accounts for the apparent bias in antelope-migration direction?
A.Warm-adapted antelope species are rarely able to tolerate cool habitats,whereas cold-adapted antelope species usually can tolerate warm habitats.
B.During global warming periods,land bridges,when present,lack habitats suitable for sustaining warm-adapted antelope species.
C.Under most climatic conditions,Africa offers a larger number of suitable antelope habitats than does Eurasia.
D.Many more species of antelope have originated in Eurasia than have originated in Africa.
E.Land bridges are more likely to exist when climate change favors migration to warmer climates than when climate changes favors migration to cooler climates.

Passage 141
2018/4/9
As of late 1980s,neither theorists nor large-scale computer climate models could accurately predict whether cloud systems would help or hurt a warming globe.Some studies suggested that a four percent increase in stratocumulus clouds over the ocean could compensate for a doubling in atmospheric carbon dioxide,preventing a potentially disastrous planet-wide temperature increase.On the other hand,an increase in cirrus clouds could increase global warming.
That clouds represented the weakest element in climate models was illustrated by a study of fourteen such models.Comparing climate forecasts for a world with double the current amount of carbon dioxide,researchers found that the models agreed quite well if clouds were not included.But when clouds were incorporated,a wide range of forecasts was produced.With such discrepancies plaguing the models,scientists could not easily predict how quickly the world’s climate would change,nor could they tell which regions would face dustier droughts or deadlier monsoons.

The author of the passage is primarily concerned with
A.confirming a theory
B.supporting a statement
C.presenting new information
D.predicting future discoveries
E.comparing points of view
2.
It can be inferred that one reason the fourteen models described in the passage failed to agree was that
A.they failed to incorporate the most up-to-date information about the effect of clouds on climate
B.they were based on faulty information about factors other than clouds that affect climate
C.they were based on different assumptions about the overall effects of clouds on climate
D.their originators disagreed about the kinds of forecasts the models should provide
E.their originators disagreed about the factors other than clouds that should be included in the models
3.
The information in the passage suggests that scientists would have to answer which of the following questions in order to predict the effect of clouds on the warming of the globe?
A.What kinds of cloud systems will form over the Earth?
B.How can cloud systems be encouraged to form over the ocean?
C.What are the causes of the projected planetwide temperature increase?
D.What proportion of cloud systems are currently composed of cirrus clouds?
