不知是否答案有误,求助

20. Some flowering plant species entirely dependent on bees for pollination, lure their pollinators with abundant nectar and pollen, which are the only source of food for bees. Often the pollinating species is so highly adapted that it can feed from-and thus pollinate-only a single species of plant. Similarly, some plant species have evolved flowers that only a single species of bee can pollinate-an arrangement that places the plant species at great risk of extinction. If careless applications of pesticides destroy the pollinating bee species, the plant species itself can no longer reproduce.

The information above, if true, most strongly supports which one of the following?

(A) The earliest species of flowering plants appeared on Earth contemporaneously with the earliest bee species.

(B) If the sole pollinator of a certain plant species is in no danger of extinction, the plant species it pollinates is also unlikely to become extinct.

(C) Some bees are able to gather pollen and nectar from any species of plant.

(D) The blossoms of most species of bees and do not attract others.

(E) The total destruction of the habitat of some plant species could cause some bee species to become extinct.

是选E吗?谢谢[em09][em09]

由于主要说的是传粉者对花的影响，所以我认为选B。

我认为是E.

文中好象在说花种和蜜蜂一一对应关系存在,就有一种情况发生:蜂死,花绝;
E说明另一种情况花绝蜂死.从而说明一一对应是存在灭种的危险.

还是你说的对。我在读提干时读错题了。解题的关键在于：
pollinating species is so highly adapted that it can feed from-and thus pollinate-only a single species of plant. Similarly,这句话。
是选E

答案给的是E,但不明白为什么蜂死,花绝;会导致另一种情况花绝蜂死

zephyr1977：
  请在看我上面的帖子中列出的英文，当时我是没理解好这句话才选错的。
特别是：Similarly，“同样地”。他后面所说的话是在阐明蜂死,花绝。但用这个“同样地”反过来解释了蜂采only a single species of plant也可能出现的情况。

i got it,thanks
