It’s a pity / shame that he should ask for money from a foreigner. It worried her a bit that her hair was turning grey. It was believed that the earth was flat in the old times. (=The earth was believed to be flat in the old times.) It will take them more than ten years to complete the project. 05、 It作形式宾语 It作形式宾语,可以指代后面真正的宾语。例如: He feels it his duty to help others. 他感觉帮助他人是他的责任。 Do you think it possible for them to send an engineer there? 你认为可能给他们派一个工程师去那里吗? She finds it boring staying / to stay at home. 她觉得待在家中很无聊。 I don’t like it when he speaks with his mouth full of food. 我不喜欢他满嘴含着食物讲话。 I would appreciate it if you can lend me a hand. 如果你能帮我的忙,我将非常感激。 06、 强调句型 结构为:It is / was + 被强调部分 + that (who)…。强调句型用来强调谓语动词以外的任何句子成分。当被强调部分是人时,也可以用who。 在使用强调句型时需注意以下几点: (1) 请注意强调句型的特殊疑问句; When was it that he got back home? Where was it that you came across him? (2) 在强调原因状语从句时,只能强调由because所引导的从句; It was because it kept on raining for days that we could not carry out our plan. (3) 在强调not …until结构时必须把not与until一起放到被强调的位置上; 本文来源:https://www.wddqw.com/doc/6ac389fb4a649b6648d7c1c708a1284ac8500520.html
