4. 例題  

Jupiter rotates very fast, once every 9.8 hours. As a result, its clouds, which are composed largely of frozen and liquid ammonia, have formed alternating dark and bright bands that circle the planet at different speeds in different latitudes.  

1. It can be inferred from the passage that the appearance of alternating bands circling Jupiter is caused by  

(A) the Great Red Spot  (B) heat from the Sun  (C) the planet's fast rotation  (D) Storms from the planet's Southern Hemisphere  

Clay particles are highly cohesive, and when dampened, behave as a plastic. Therefore the higher the 11 clay content in a sample, the more refined and durable the shapes into which it can be molded.  

2. Which of the following can be inferred from the passage about a soil sample with little or no clay in it?  

(A) It is not very heavy.  (B) It may not hold its shape when molded.  (C) Its shape is durable  (D) Its texture cannot be classified  

The first birds appeared during late Jurassic times. These birds are known from four very good skeletons, two incomplete skeletons, and an isolated feather, all from the Solnhofen limestone of Bavaria, Germany. Not only were the bones preserved in these skeletons, but also were imprints of the feathers. If the indications of feathers had not been preserved in association with Archaeopteryx, it is likely that these fossils would have been classified among the dinosaurs, for they show numerous theropod characteristics.  

3. It can be inferred from the passage that the Archaeopteryx were classified as birds on the basis of  

(A) imprints of bones  (B) imprints of feathers  (C) the neck structure  (D) skeletons  

4. It can be inferred from the passage that theropods were  

(A) dinosaurs  (B) birds  (C) Archaeopteryx  (D) crows  

Molt of the flight feathers is the most highly organized part of the process. Some species, for example, begin by dropping the outermost primary feathers on each side (to retain balance in the air) and wait until the replacement feathers are about one-third grown before shedding the next outermost, and so on. Others always start with the innermost primary feathers and work outward. Yet other species begin in the middle and work outward on both sides. Most ducks shed their wing feathers at once, and remain flightless for two or three weeks while the replacement feathers grow.  

5. It can be inferred from the discussion about ducks that the molting of their flight feathers takes  

(A) a year  (B) a season  (C) several months  (D) a few weeks
