介词是一种用来表示词与词、词与句之间关系的虚词,英语中时间状语通常由in, on, at, for等介词引起,但有些情况下时间状语前不用介词。现就这几种情况加以归纳。 一、 当时间状语是today, yesterday, tomorrow, tonight, yesterday/tomorrow morning(afternoon, evening)等时,其前不用介词。例如: There was a football match yesterday evening.昨天晚上有一场足球赛。 They will go to the zoo tomorrow.明天他们将要去动物园。 二、由this, that, these, those等构成的短语前不用介词。例如: I'll visit my grandparents this week.这一周我要去看望我的祖父母。 They are picking apples on the farm these days.这些天他们在农场摘苹果。 三、由形容词last,next等指示代词修饰的名词词组用作时间状语时,前面的介词at, on, in一般省略。例如: I saw him in the street sometime last week.上周我在街上见过他。 Please come to school earlier next time.下次请早点来学校。 但是,如果不是介词at, on, in,而是其他类型的介词,一般不能省略。如:I haven't been to my hometown since last year.从去年以来我就没回过家乡。 四、在以“the day (week, month, year)+before/after…”构成的时间状语前不用介词。例如: Where did you go the day before yesterday? 前天你去哪里了? They'll have a party the day after tomorrow.他们后天将举行一个聚会。 五、由every, each等表示频率的副词构成的短语用做时间状语时,其前不用介词。例如: Do you watch TV every day? 你们每天看电视吗? They go to school by bike each day.他们每天骑自行车去上学。 六、由on引出的特定日子,可以省略介词on。例如: I can see him (on) New Year’s Day.在元旦我可以看见他。 七、for通常引出一段时间,当与表示静态的动词连用时可以省略。例如:I have stayed there (for) three hours.我在那里已经呆了三个小时。 注意:1.当与动态动词连用,或在句首及否定句中,介词for不能省略。如:I haven't heard from him for three years.我三年没有收到他的信了。 2.当walk, run, drive, travel等动词连用表示距离时,for可以省略。如: He ran (for) a mile in four minutes.他四分钟跑了一英里 八、以all构成的短语做时间状语,如all day, all the week, all the year等前面通常不用介词。例如: My mother was busy all day yesterday.昨天妈妈忙了一整天。 The girl was ill in bed all the week.这个女孩生病了,卧床整整一周。 注意:以all开头的短语前,介词通常省略。如: I haven't seen her all day.我整整一天没有看见他了。 九、当at about…表示时间时,介词at可以省略。例如: The sun rose (at) about six o'clock today.今天太阳大约在六点升起。

Since last year, this community has built over 20 small supermarkets and a new larger one. It is also reportedly said that the community is planning to build many new large high-rise buildings, and in the northern part of the community planning to build a new park. (答案是正确的, 毕竟英语是我的母语!)

the day it opened 是时间状语,可以不加介词。比如,last week也是时间状语,我可以说I went to the World Expo last week.在这里也是一样的,it opened 修饰了the day, 如果换成简略的that day 是不是就可以理解了呢?
