答案 The first diagram illustrates the stages in the life of a lady bird, while the second diagram shows its body structure. Overall, there are four stages in the life cycle of a lady bird from egg to adult insect. The lady bird’s anatomy is characterised by colourful elytra of red and black.
Initially, eggs are laid on the underside of a leaf and remain there for two to five days. After this, larvae hatch out and continue in that form for 21 days. At the end of the third week, the pupa stage begins where the larvae pupate by curling into a pupa on the backside of a leaf and this lasts for seven days. At the end of this stage, an adult lady bird emerges and the life cycle starts again.
The second diagram shows that the lady bug has bright red elytra with black spots that cover both the wings and the abdomen. It also has six legs in total, three on each side. On its head, it has eyes and antennae, while just behind the head there is the pronotum.
解析 左图是一种lady bird(瓢虫)的生命循环(life cycle)示意图。右图是该种昆虫的anatomy(该词较难，但从图中的内容来看，可推测该词大致为“构造，结构”，本文行文可分三段：概况两图内容一段；生命循环图一段；构造图一段。
Lady bird的整个生命流程为四个阶段，生命流程图常选取虫卵孵化的一步为起点描述。描述时注意要将各阶段的时间长度添加进去。
右图中出现较多生词，但描述时只要有条理地将lady bird的身体构造描述出来即可。从图中可以看出，lady bird最大特点是背部有红色的elytra；下面是abdomen和wing；躯干上应该是有六条腿(leg)；头部(head)结构则包括eye和antenna；躯干和头部之间是pronotum。
