Lack of rainfall since the end of last year has led to serious drought (干旱)in the northern part of our country, and frequent cold snaps (寒流) this winter (1) (make) the situation worse. Top-level drought warning declared (宣布最高级别干旱预警) On 5 February, our country declared a top-level emergency in the drought-hit provinces.

Read the passage again and raise questions as required. 再读一遍短文,并根据要求写出问句。 1.你想要了解这场干旱是怎么开始的。 ? 2.你想要了解这场干旱主要发生在什么区域。 ? 3.你想要了解这场干旱有多严重。 ? 4.你想要了解政府采取了哪些抗旱措施。 ? 5.你想要了解人工降雨是否有效。 ? I. Choose what it refers to in each sentence. 1. C。“It is a bit windy today.” 描述的是今天的天气状况，“it” 指代 “weather”，所以选 C。 2. A。“It is half an hour's walk to the city centre.” 表达的是到市中心的距离，“it” 指代 “distance”，所以选 A。 3. E。“It was nearly midnight when she came back.” 说的是她回来的时间，“it” 指代 “time”，所以选 E。 4. B。“It's autumn now.” 指的是现在的季节，“it” 指代 “season”，所以选 B。 5. D。“It's 15 October.” 表示的是日期，“it” 指代 “date”，所以选 D。 II. Write the questions according to the underlined parts. 1. How far is it from his new flat to the office? 对 “ten minutes' drive”（距离）提问，用 “How far”，所以问句是 “How far is it from his new flat to the office?”。 2. How long did it take for the parcel to reach Australia? 对 “ten days”（时间）提问，用 “How long”，原句是一般过去时，借助助动词 “did”，“took” 还原为 “take”，所以问句是 “How long did it take for the parcel to reach Australia?”。 3. How can you express what you like and don't like? 对 “by writing or drawing”（方式）提问，用 “How”，所以问句是 “How can you express what you like and don't like?”。 4. What did he make a small hole in the window shade for? 对 “to let in a skinny beam of sunlight”（目的）提问，用 “What...for”，原句是一般过去时，借助助动词 “did”，“made” 还原为 “make”，所以问句是 “What did he make a small hole in the window shade for?”。 III. Complete the passage with the proper forms of the given verbs. 1. have made。“frequent cold snaps this winter” 和前面的 “Lack of rainfall since the end of last year” 并列，对现在造成了影响，导致情况更糟，用现在完成时，主语 “frequent cold snaps” 是复数，所以用 “have made”。 2. ordered。根据时间状语 “On 5 February” 可知，该句时态是一般过去时，所以用 “ordered”。 3. to fight。“order sb. to do sth.” 是固定用法，表示 “命令某人做某事”，这里是 “order all - out efforts to fight...”，所以用 “to fight”。 4. were。根据语境可知，这里描述过去的情况，用一般过去时，主语 “clouds” 是复数，所以用 “were”。 5. rises。“as” 引导的时间状语从句遵循 “主将从现” 原则，主句用一般将来时 “will be diverted”，从句用一般现在时，主语 “temperature” 是第三人称单数，所以用 “rises”。 6. to increase。“open...to do sth.” 表示 “打开…… 来做某事”，这里打开水闸是为了增加其他省份的水供应，所以用 “to increase”。 II. Read the passage above again and decide whether the following statements are true (T) or false (F). 1. F。根据 “Lack of rainfall since the end of last year has led to serious drought (干旱) in the northern part of our country” 可知，是去年年底以来降雨不足导致了干旱，而不是频繁降雨，所以该句错误。 2. T。根据 “On 5 February, our country declared a top - level emergency in the drought - hit provinces.” 可知，2 月 5 日国家在受干旱影响的省份宣布了最高级别的干旱紧急状态，所以该句正确。 3. F。根据 “Though several areas are in the east, most of the hardest - hit provinces are in the north.” 可知，受灾最严重的省份大部分在北方，而不是都在东部，所以该句错误。 4. F。根据 “Parts of the hardest - hit areas got light rain after the artificial precipitation (人工降雨). However, clouds (4) were thin and moving out of a few regions, and that made conditions poor for more rain - making.” 可知，人工降雨只带来了小雨，并非大雨，所以该句错误。 5. T。根据 “Our country has prepared to divert (转移) water from its two longest rivers to irrigate (灌溉) the drought - hit farmland. Water in the main river will be diverted to some of the drought - hit provinces as temperature (5) rises and water demand grows.” 可知，国家计划从主要河流调水到一些受干旱影响的省份来抗旱，所以该句正确。 IV. Read the passage again and raise questions as required. 1. How did the drought start? 2. Where did the drought mainly happen? 3. How serious was the drought? 4. What measures did the government take to fight against the drought? 5. Was the artificial rainfall effective? 学科网（北京）股份有限公司 $$
