【題目】This kind of plant is ________________ seen in our city because it lives 4, 500m above sea level and is hard to find.

A. commonly B. always C. seldom D. easily

【答案】C

【解析】本題用詞義辨析法辨析。commonly通常；always總是；seldom很少；easily容易地。根據(jù)＂它生長在海平面4,500米以上并且很難發(fā)現(xiàn)＂推斷它很少被看到。故選C。

【題目】Mr. Ellis is very old. He has seen many changes in his hometown. He knows that things are different now. But he never forgets the old days. He often talks about his favorite birds, the robins(一種小鳥— 知更鳥). “When I was a boy, these houses were not here. These were wild fields and tall trees. Every spring the robins would come. Thousands of them would fly up to the south. They spent the winter in the south. Some would build their nests(巢)in the trees near our houses. Then people started to cut down trees, and they built more houses. The robins stopped coming. They couldn’t build their nests near our houses because there were no trees.” “Now there are too many houses and too many roads. There are no places for the robins. They do not come any more.”

【1】Mr. Ellis often talks about his family.
