1. Temperature ( condition ) is ( one of ) the ( most ) important ( considerations ) of floriculture.
A,
我想用conditioning是指温度调节, 而不是温度状况(condition), 从句子意思来考虑.
另外, 最后一个单词,floriculture不明白是什么意思
2.It is ( difficult ) ( in communication ) that ( causes ) visitors to Africa ( the most ) trouble.
A, 应该是difficulty. 因为这是IT做形式主语的强调句型" it is difficulty...that.... 强调的是主语.
我们通常说的: it is difficult to do sth句型与本句不同, 如果改写为普通句子, 就是:
Difficulty in communication causes visitors to Africa the most trouble. 顺便翻译一下:
正是交流上的困难给去非洲的旅行者带来最大的麻烦.
3. The ( impact on ) earth of a large meteorite was a ( possibly ) contributing factor when ( 70 percent ) of all living species became extict 65 ( million ) years ago.
B, 应改成possible, 这里修饰的是factor,不是contributing, 所以用形容词posibble

我有我可以
