Maria, a 91-year-old woman, has an unbelievable experience last week. A group of thieves broke in her house but took nothing away with them. Maria recalled that the windows were broken and that all her box were opened, but nothing was missing. Instead, she found a handwritten note on the table that was said, “This is help you to get by.” Beside the note there was some money. It seemed that the thieves realized how poor Maria lived and decided not to take something—but to help. One policeman who has been working for 40 years is surprising by this event too. Later Maria kept the note received from her friendly thieves or used the money to buy sweets for his great grandchildren.

【解析】（1）考查时态，根据文中第一句的“last week ”意思是上周，时间为过去，所以应该用过去时，故改为had.
(2)考查固定短语，这是短语break into，意思是破门而入，故改为into.
(3)考查名词复数形式，boxes,为常用名词，意思是盒子，这里用名词复数故改为boxes.
(4)考查句子结构，he said 为主谓结构，故不需要系动词，故删除was。
(5)考查固定句式，This is to help you to get by.意思是这是为了帮助你过去。故加了一个to表示为了。
(6)考查副词，此处poor是用来修饰live,修饰动词用副词，故改为poorly。
(7)考查不定代词，因为not to 表示否定，anything用于否定句中，something用于肯定句中，故改为anything 。
(8)考查动词，形容人惊讶用surprised ，形容物使人惊讶用surprising 此处形容警察，故改为surprised。
(9) 考查连词，Maria kept the note received from her friendly thieves or used the money to buy sweets for his great grandchildren.意思是玛利亚把这张纸条交给了她的朋友们，或者用这笔钱为她的孙子们买糖果。这两个句子是肯定句表示并列关系，故改为and ，or用于否定句。
(10)考查形容词性物主代词，玛利亚是一位女性，故改为her。
