这句话是进行时还是主系表The shop is just opening. how friendly the shop assistants are这句话对吗?还是 what friendly the shop assistants are? The shop has been open since 2008.这句话有错吗?since 2008前是延续还是瞬间的? 在商店是in shop ,in the shop 还是at shop?还是什么? 是I went to the shop I went to the shop还是I went to shop? Sometimes I go to the shop ___on__saturday 这句话的介词用on 还是at 为什么在英语句子中有些有often的句子还是用现在进行时啊例如My often go shopping withfriends on sundays She often shop in the mall但often是一般进行时态的标志啊 在商店英语到底是at the shop还是in the shop? 翻译、、在超市购物、、是shop at the supermarket 还是 shop in the supermarket 是shoe shop 还是shoes shop? 小学六年快乐英语第八课I am going to the zoo是将来时还是进行时这句话在快乐英语第八册第十七页 It has been very difficult getting to the bottom of some complicated problems.这句话是现在完成时还是现在完成进行时? Tommy`s been to the toilet three times this morning.这句话的时态是什么?主要问这句话的时态是一般过去时还是过去进行时还是其他的时态? in the shop 还是at the shop具体说明 the shop for clothes还是the shop of clothes She was talking to herself.这句话是现在进行时还是过去式 这句话是现在进行时还是一般现在时I am doing my homework now the shop will___in a deep night.be closed还是close我记得我学的时候是：商店关门不用被动语态,那么这句话为什么选第一个（答案给的）.请说明原因,
