IELT Reading Day3: IELTS 8-4-3
Collecting Ant Specimens
1.错题总结
题目：Classify the following statements as referring to
A hand collecting
B using bait
C sampling ground litter
D using a fitfall trap
Write the correct letter A, B,C,or D in boxes 31-36 on your answer sheet.
31: It is preferable to take speciments from groups of ants. 从蚁群中提取标本是较好的
错选：B using bait, 正确：A hand collecting.
原文：This will ensure that all individuals are of the same species,and so increase their value for detailed studies.这将确保所有的个体都属于同一物种，从而增加它们对详细研究的价值。
from groups of ants = of the same species.
33:It is a good method for species which are hard fo find.
正确： B using bait
原文：
This often increases the number of individuals collected and attracted and attracts species that are otherwise elusive.
这通常增加了个体的数量，吸引和吸引物种，否则是难以捉摸的。
elusive /ɪˈluːsɪv/难 (找、形容、记、取得) 的
elusive = hard to find.
34:Little time and effort is required.
错选：C sampling ground litter 正确：D using a pitall trap n 问题，困难；隐患；陷阱 〔捕捉动物的〕夹子，罗网，陷阱
原文：
It will also allow more litter to be sampled when using a limited number of funnels.
litter :FOREST 森林
[U] dead leaves and other decaying plants on the ground in a forest
(also 又作leaf litter)
〔森林里的〕落叶，枯枝落叶层
One advantage of pitfall traps is that they can be used to collect over a period of time with minimal maintenance and intervention.
maintenance /'meɪnt ə nəns/ n.维护，养护，保养
intervention /ɪntə'venʃ(ə)n/ n.干涉，干预，介入
minimal maintenance and intervention = limited number of funnels.
