Whichof the sentences below best expresses the essential information in thehighlighted sentence in the passage? Incurred choices change the meaning inimportant ways or leave out essential information.
○Ecologists now think that the stability of an environment is a result ofdiversity rather than patchiness.
○Patchy environments that vary from place to place do not often have highspecies diversity.
○Uniform environments cannot be climax communities because they do notsupport as many types of organisms as patchy environments.
○A patchy environment is thought to increase stability because it is ableto support a wide variety of organisms.
是这个吧？句子是 Manyecologists now think that the relative long-term stability of climaxcommunities comes not from diversity but from the “patchiness” of theenvironment, an environment that varies from place to place supports more kindsof organisms than an environment that is uniform
个人认为句子主旨是在说patchy比diversity更稳定 而不是climax communities 注意这 long-term stability of climaxcommunities
所以主干是stability而不是climax communities 所以C选项不合理
你说的是最后那个6选3的主旨题吧 有的选项即使是对的 但跟文章主旨不联系 也是不能选的..
