参考答案：
1.答案B。limited的含义是"有限的"，前三个被选项的语义相近，都有"小的"的含义（low是"低的"）。所以这道题是考辨词。解题思路：抓住句子中与划线部分相关的结构或用词特点。看原题干：limited后是number， 而number是可数名词。small修饰可数名词，little修饰不可数名词， 而tiny的语义是"微小的"，一般指体积。所以答案是B。
2.答案D。在该句中yield 是用作名词（因为该词的前面有不定冠词a），解题思路：抓住句子中与划线部分相关的结构或用词特点。能与不定冠词a搭配使用的被选项只有C和D（气候，倾向， 风气，如：a mild climate温和的气候）。再借助句子中其他特征词：farm，判断harvest"收成"是答案。
3.答案A。画线短语是介词短语，解题思路：对于短语含义的确定可以借助各成分词的基本含义或借助短语中核心词的基本含义。借助该介词短语中的核心词形容词most和名词 part，判断该短语与"大多数有关"，所以A是答案。也可依据most 或part在字典中查找该短语，得出该短语的含义。
4.答案A。画线短语是动词短语，对于该短语的语义有两种查找方法：1.利用动词do，直接在字典中查找do away with 这个短语的语义，不难得出该短语的语义是"去掉"，所以A是答案；2.利用该短语中的词义推测：away是"离开"，而备选项中： set up是"建立"， repair是"修理"， paint 是"描绘"，都与"离开"无关，所以只有get rid of是答案。
5.答案B：根据划线词所在结构和其基本词义"检查"判断B是答案。该题也可借助句意选择答案。

go over v.(对...进行)仔细检查, 复习
look up v.向上看, 尊敬, 仰望, 查寻
look up to v.尊敬,仰望
find out v.找出, 发现, 查明(真相等), 认识到, 想出, 揭发
6.答案A：somewhat adv.稍微, 有点, 有些
7.答案B：注意词义跨度大的词。minute在此是形容词"细小的、细微的"
timely adj.及时的, 适时的
accidental adj.偶然的, 无意中的
significant adj.显着的
8.答案C。解题思路：借助句意："一项国际公约禁止买卖濒危野生动物和植物。"
ban vt.禁止, 取缔(书刊等).该题也可以借助句意或句子中用词来进行答案的选择。
promote（常与to连用）提升, 宣传，推销（商品）, 支持, 促进, 鼓励
forbid 禁止，不准，不许
exclude 排除, 拒绝(接纳, 考虑), 除去, 不把...包括在内, 取消, 撤销
