time)

11. They visited the house where comrade Zhou Enlai once lived and worked. (adverbial of place)

Then let the students pay attention to some difficult points as follows.

The use of "that": sometimes "that" can't be used, for example,

a. They are boys with whom I went to school. (object, after preposition, "that" is not used)

b. The case to which you are referring to is now closed. (object, after preposition, "that" is not used)

c. I told the story to John, who later did it to his brother. (subject, non-restrictive attributive clause, "that" is not used)

d. His speech, which bored everyone, went on and on. (subject, non-restrictive attributive clause, "that" is not used)

But sometimes it must be used, for example,

a. This is all that I want to say. (after: all, few, little, much, something, nothing, anything, everything, any, every, no, some, "that" must be used, if it is not the subject, "that" can be omitted.)

b. I agree every point that he referred to just now. ("that" can be omitted)

c. This is the most beautiful place that I have ever seen. (after superlatives or ordinal numerals, "that" can be omitted)

d. This is the very book that I want to borrow. (after: the very, the only, the same, object, "that" can be omitted)

e. They talked of things and persons that they remembered in the school. (after both person and thing, object, "that" can be omitted)

The last important point is: where, when, that, etc. for example,

a. This is the museum which / (that) we visited last week. (object)

b. This is the museum where (in which) my father once worked. (adverbial)

c. Do you still remember the days which / (that) we spent in the countryside? (object)

d. Do you still remember the days when (during which) we worked in the countryside? (adverbial)

e. The reason which / (that) he provided was not what we expected. (object)
