文章结构分析
permanent第1题
解析：真实信息题。答案A
∙与原文信息Success in colonization depends to a great extent on there being a site available for colonization---a safe site where disturbance by fire or by cutting down of trees has either removed competing species or reduced levels of competition and other negative interactions to a level at which the invading species can become established相符
迷惑选项
∙B 偷换概念，原文信息为reduced levels of competition and other negative interactions to a level而不是increas negative interactions with other organisms on the site.
∙C 原文无提及该信息
∙D 信息杂糅，原文提及fertility of a site但是原文没有将Disturbance reduces fertility联系起来
第2题
解析：词汇题。答案A
∙Virtually意为“事实上，几乎；实质上”故选A: almost totally
迷惑选项
∙B usually意为“通常，经常”
∙C consistently 意为“一贯地；一致地；坚实地”
∙D unnaturally 意为“故意地；违反习俗地；不合乎自然规律地”
第3题
解析：修辞目的题。答案C
∙该信息起解释说明的作用，相当于举例，服务的对象为For a given rate of invasion, coloni
zation of a moist, fertile site is likely to be much more rapid than that of a dry, infertile site becau of poor survival on the latter.
迷惑选项
∙A 原文无提及该信息
∙B 混淆原文的关系，原文提及the kind of sites that may be invaded by weeds，但是提及a construction site是说明不能被植物生存的环境
∙D 与原文相矛盾，原文信息为the soil has been compacted or removed to expo a coar, infertile parent material may remain virtually free of vegetation即不能改种soil不能生存植物
第4题
解析：词汇题。答案C
∙Despite意为“尽管…，不管….”故选C: even though

∙B almost never意为“几乎永不”
∙D perhaps意为“或许，大概”
第5题
解析：句子简化题。答案B
∙原句分为两层，因果关系。第一层：Pioneer species有很高的入侵比率。第二层：原因是产生大量的果实以及有更有效率的传播方式
迷惑选项
∙A 句内信息的杂糅，原文提及相应信息，但是彼此之间关系是错误的，原句主体是Pioneer species有很高的入侵比率的原因
∙C 句内信息的杂糅，原文无提及produce their largest numbers of propagules during the earliest stages of their colonization的关系，原文关系为Pioneer species---tho that occur only in the earliest stages of colonization
∙D 句内逻辑错误，原句描述主体为Pioneer species有很高的入侵比率而不是Pioneer species reproduce very quickly and efficiently
第6题
解析：推理判断题。答案B
∙因果类Infer.原文信息为Many plants depend on wind for dispersal and produce abundant quantities of small, relatively short-lived eds to compensate for the fact that wind is not always a reliable means of reaching the appropriate type of habitat. Alternative strategies have evolved in some plants, such as tho that produce fewer but larger eds that are disperd to suitable sites by birds or small mammals or tho that produce long-lived eds，因果关系为小种子产生的多来弥补风传播不稳定的影响，大种子产生的少故采用动物传播，大小的对比说明大种子不能用风传播
迷惑选项
∙B,C 原文均无提及该信息
∙D 偷换概念，原文信息为tho that produce long-lived eds而不是Large eds are short-lived
第7题
解析：指代题。答案D
∙结合原文语意关系判定，指代前文that are disperd to suitable sites by birds or small mammals or tho that produce long-lived eds的信息

迷惑选项
∙A,D 原文均无提及该信息
∙B 偷换概念，原文提到pioneer species can be found in large numbers on some forest floors但是无提及prefer forest floors for colonization purpos
第10题
解析：真实信息题。答案D
∙与原文信息Seeds of a given species exhibit a wide range of germination dates, increasing the probability that at least some of the eds will germinate during a period of favorable environmental conditions.相符
迷惑选项
braver
∙A 偷换概念，原文信息为at least some of the eds will germinate during a period of favorable environmental conditions而不是eds only during favorable climatic conditions
