如剑7 Test 4 Section 2最后一题的文字答案为:And finally let‘s pass by the WaterbirdRefuge.This area is in a sheltered part of estuary, that’s why the park‘sviewing shelter is a favourite spot for bird watchers who can use it to spythrough binoculars.这边出现了几个比较生僻的词语:estuary河口,binoculars双筒望远镜,而此题的答案viewingshelter 也是一个比较难的词语,因此在这个地方如果不看文字答案将很难听明白。
