amd settings有什么用:英语选择题

c
although是从属连词,表示“虽然……但是……”,引导让步状语从句,从句置于主句前或后,可用though替代although, 在主句前不能加but。例如:

Although / Though it was expensive, we decided to buy the computer.虽然价格昂贵,但我们还是决定把这台计算机买下来。

We had a good time, although / though we only stayed there for a few days.虽然我们仅在那里呆了几天时间,但是我们过得很愉快。
even though是从属连词,表示“即使”、“纵然”,引导让步状语从句,表示一种假设或推断。从句放在主句前或后,可用even if替代even though。例如:

Even though / if you don’t like wine, try a glass of this. 即使你不喜欢喝酒,也喝一杯试试。

We’ll stand by you even though / if you don’t succeed. 纵然你不成功,我们也会支持你的。

although (虽然),even though(即使),

though, although在句首表“尽管”两者都可以用。
even if (=even though)

though,although,even if (though)均可引导让步状语从句，但在侧重假设或推断时要用though或as if(though),例如：
Although it rains heavily,we shall still go out

上句中although应改为even if (though)或though。

再如：Though(Even though) everyone deserts you, I will not.

应该选C
although是从属连词,表示“虽然……但是……”,引导让步状语从句,从句置于主句前或后,可用though替代although, 在主句前不能加but。例如:

Although / Though it was expensive, we decided to buy the computer.虽然价格昂贵,但我们还是决定把这台计算机买下来。

even though是从属连词,表示“即使”、“纵然”,引导让步状语从句,表示一种假设或推断。从句放在主句前或后,可用even if替代even though。
如：Though(Even though) everyone deserts you, I will not.

Although(though)后不加but,所以选c是对的！他们说的都有理！
