But I like our modern library and the new Science Museum. Life in the city is exciting and full of opportunities. Hi, I’m Wang Hong. I live in the countryside. In my grandparents’ time, life was very hard. They farmed with their hands and had few machines. Their houses were small and simple. Now, life is much better. We have new roads connecting （连接） our village to the town. We can buy things online. My family uses a machine to help with farming. We even sell our fruits online to people in cities.

Have; been; did; open 解析：第一空yet（用于疑问句、否定句）是现在完成时标志，主语为you，助动词用Have，be的过去分词为been；第二空询问开业的过去动作，用一般过去时，助动词did后接动词原形open。 12. opened; went 解析：last Friday、last Saturday 均为一般过去时时间标志，open和go的过去式分别为opened、went。 13. will bring / am going to bring 解析：tomorrow（明天）为一般将来时标志，可用will+动词原形或be going to+动词原形两种结构。 14. has built 解析：in the past 10 years（过去十年间）为现在完成时标志；主语the government为单数名词，故填has built。 15. have improved 解析：结合语境，十年建设带来生活的持续改善，动作从过去延续至现在，用现在完成时；主语people’s lives为复数，故填have improved。 Ⅱ. 用方框中所给单词的适当形式填空 所给单词含义：wide 宽阔的；track 小径、轨道；digit 数字；audio 音频的；dirt 泥土 1. digital 解析：修饰名词payments需用形容词，digit对应的形容词digital意为“数字的”，digital payments 为固定搭配，意为“数字支付”。 2. dirty 解析：get为系动词，后接形容词作表语；dirt（泥土）的形容词形式为dirty（脏的），贴合“衣服沾满污渍”的句意。 3. wide 解析：用形容词修饰名词bridge，wide本身为形容词，表“宽阔的”，a wide bridge 意为“一座宽阔的桥梁”。 4. audio 解析：结合后文listening skills（听力技巧），audio作形容词表“音频的、有声的”，audio book 为固定搭配“有声读物”。 5. track 解析：forest track 为固定搭配“林间小径”，that narrow修饰单数名词，因此填单数形式track。 Ⅲ. 短文填空 文章主旨：对比改革开放前后的生活变化，主要考查一般过去时、一般现在时、现在完成时及固定短语 1. to watch 解析：固定句型used to do sth. 表示“过去常常做某事”，此处填不定式to watch。 2. didn’t have 解析：时间状语In the 1980s（20世纪80年代）提示一般过去时，实义动词have的过去式否定形式为didn’t have。 3. by 解析：固定搭配by train 表示“乘火车”，为交通方式固定表达，无需变形。 4. took 解析：and连接并列谓语，时态与前文一般过去时保持一致，take的过去式为took。 5. have bought 解析：侧重过去的动作（买车）对现在造成的影响（如今家家户户有车），用现在完成时，主语为复数，故填have bought。 6. and 解析：并列连词连接两个并列谓语work online和talk with friends，表并列关系，填and。 7. have brought 解析：这些变化从过去持续至今，极大改善了人们的生活，强调对现在的影响，用现在完成时。 8. moved 解析：in 2010 为具体过去时间，句子用一般过去时，move的过去式为moved。 9. have seen 解析：从2010年迁居至今，持续见证城市发展，动作从过去延续到现在，用现在完成时。 10. will 解析：in the future（在未来）为一般将来时标志，will+动词原形表将来，贴合句意。 VI. 阅读表达 1.
