What is special about this year’s dolphin stranding?
Some scientists are trying to solve a mystery on Cape Cod. Dolphins have been getting stranded there. It’s not completely unusual. There are typically around 120 strandings per year. (6) But more than 100 dolphins have gotten stranded in the first month of this year. Sometimes they’re washing 10 at a time.
At least 81 of these dolphins were either found dead or died shortly after being discovered. One animal welfare group director called the number "disturbing". Now, no one’s certain what’s causing the dolphin deaths.
A local harbor master says changes in water temperature could be a contributing factor. Usually the Cape Cod harbor ices over in winter, so dolphins don’t get close to the shore. But the harbor master says now that the water’s warmer, more dolphins are showing up than ever before.

选项
A、The number of stranded dolphins is very large.
B、The death rate of the stranded dolphins is very high.
C、The mystery of dolphin stranding is finally solved.
D、Dolphins got stranded on the ice near the shore.
答案
A
解析
推断题。文中讲到海豚搁浅并不稀奇(not unusually),常年每年有120起。然而今年则是在一个月内就发生了100多起,这很不寻常也很令人不安:There are typically around 120(strandings)per year.But more than 100 dolphins have gotten stranded in the first month of this year。因此答案为A。
