划分主语从句还是宾语从句的问题

Who can tell me the question is wrong.句子开头单词没有大写。此外,句末用句号,还是问号?改为:Who can tell me the question is wrong?技巧是:先弄清楚句子意思。然后是:句意决定形式,形式服从内容。你觉得第二种划分,对吗? (Who can tell me the question) is wrong?

mixed 与 mixing 用法的区别

We could hear the sound of the rain and our footsteps mixed with our laughter.mixed with our laughter 是过去分词短语作 footsteps 的定语,不是伴随状语。直译:与我们笑声混在一起的脚步声。可译为 “和我们笑声交织在一起的脚步声;夹杂着我们笑声的脚步声”。分析句子成分或非谓语动词,首先要了解该动词的用法或结...

关于物质名词数的问题

在英语语言的思维中,并没有把vegetable 看作为不可数的物质名词,而是泛指一种蔬菜。例如:Cabbage is a kind of vegetable.你见到这句子时,不要因为前面有了 a kind of 就认为vegetable不可数。其实,可数名词和不可数名词之前都可以加a kind of表示“种类”,例如:a kind of bike,a kind of coal。此时,无论可数名词与...

Richard Johnson was a great US general, starting with his time as a soldier during Vietnam.此题选 during,与 time 相呼应。Vietnam 应该指 “越南战争”。

单词estimated的使用

 Today,an estimated 96% of households in Kenya use M-Pesa. 这里,estimated 是个强调形容词,用在数词之前作定语,强调这个数字的程度如何。尽管修饰的数词后面是复数名词,也要加不定冠词。网友说的It's estimated that 96% of households in Kenya…,是被动结构,用形式主语代替从句。是两个不同的结构。 形容词 m...
