句子改错 1.safety class,a toughened glass sheet,is six times strongers than untreating glass.
每题都有一个错误,untreating 改成untreated.我觉得safety应该改成safe呀,safety不是名词吗?
2.Scorpions,whch are normally lone,have develped a cautious mating ritual.
答案是该lone 成alone 这两词有什么不同吗?
3.The diameterof the sun is more than one hundred times greater than the Earth.
答案是该the Earth 成that of the earth 为什么呢?

1) 我觉得第一题你可能理解错了,safety class是安全等级的意思.这句话的意思是钢化玻璃板的坚硬程度是普通玻璃的六倍.普通玻璃,也就是untreated glass 未经处理的玻璃.有被动含义,所以用过去分词作定语.（stronger是你打错了吧,如果这一行只有一个错误的话~）
2)lone和alone虽然意思接近,但是lone多做定语,alone多做表语.这句话中“are (normally)+?”是个系表结构,所以要用alone.
3)第三题是考察比较级的用法,我们在比较两样东西时要遵循对等的原则.这道题里比较的对象是太阳的直径和地球的直径.要注意,是地球的直径,而不是地球.所以用了 that of the earth.that指前文中的diameter（直径）.
