英語語法強(qiáng)調(diào)句知識(shí)點(diǎn)：這道題中的did表強(qiáng)調(diào)
【導(dǎo)語】英語語法讓很多學(xué)生都頭疼，因?yàn)閺?fù)雜難懂的句式和詞組有時(shí)難以記憶。英語網(wǎng)為大家整理了英語語法大全，希望對(duì)同學(xué)們的英語語法學(xué)習(xí)有所幫助。更多內(nèi)容盡在英語網(wǎng)。
請(qǐng)看下面的題：
An awful accident _________, however, occur the other day.
A. does B. did C. has to D. had to
【分析】此題正確答案應(yīng)選B，句末的 the other day 意為前幾天，所以句子應(yīng)用過去時(shí)態(tài)，而選項(xiàng)D填進(jìn)去不合題意，故選B。此句有兩個(gè)難點(diǎn)：一是句中插有 however 一詞，分散了同學(xué)們的注意力;二是所填選項(xiàng)B為許多同學(xué)所不熟悉的強(qiáng)調(diào)用法。又如(答案均選B)：
(1) Your mother _________, however, say that to us that day.
A. does B. did C. is doing D. was doing
(2) Our math teacher _________, however, speak English well.
A. doing B. does C. is doing D. was doing
