　　141. One way to do this is to find a sheltered roost. Solitary roosters shelter in dense vegetation or enter a cavity-horned larks dig holes in the ground and ptarmigan burrow into snow banks-but the effect of sheltering is magnified by several birds huddling together in the roosts, as wrens, swifts, brown creepers, bluebirds, and anis do.

　　The word "magnified" is closest in meaning to which of following?

　　(A) caused

　　(B) modified

　　(C) intensified

　　(D) combined

　　142. The second possible benefit of communal roots is that they act as "information centers." During the day, parties of birds will have spread out to forage over a very large area. When they return in the evening some will have fed well, but others may have found little to eat.

　　The word "forage" is closest in meaning to which of following?

　　(A) fly

　　(B) assemble

　　(C) feed

　　(D) rest

　　143. Finally, there is safety in numbers at communal roosts since there will always be a few birds awake at any given moment to give the alarm. But this increased protection is partially counteracted by the fact that mass roosts attract predators and are especially vulnerable if they are on the ground.

　　The word "counteracted" is closest in meaning to which of following?

　　(A) suggested

　　(B) negated

　　(C) measured

　　(D) shielded

　　144. Drying, smoking, and salting could preserve meat for a short time, but the availability of fresh meat, like that of fresh milk, was very limited; there was no way to prevent spoilage.

　　The word "prevent" is closest in meaning to which of following?

　　(A) estimate

　　(B) avoid

　　(C) correct

　　(D) confine

　　上面是几道词汇题，大家都会了么?其实词汇掌握并不难，通过做题是的方法。在语境中体会词汇的用法才能掌握的更牢靠。祝大家取得好成绩。
