【文章內(nèi)容簡介】 days to plete one full revolution around the Sun.So, every four years we get an extra day, which falls on 29th February. However, as mentioned earlier, it is in fact just under a quarter of a day. So, by rounding it up, we put the calendar out of sync again which means that after a while we have too many days.That imbalance has to be readdressed. Otherwise after 400 years we39。d end up with three extra days. So in 1582, they realized that every turn of a century should skip the extra day to subtract those three extra days. This is why 1700, 1800 and 1900 aren39。t leap years.But wait, there39。s more. The year 2000, the millennium, is a leap year. That39。s because over a period of four hundred years we only need to remove three days. So, every 400 years the turn of the century is a leap year. This means the next time you hear people saying, leap years happen every four years, you can tell them why they39。re wrong.12. What can be learned from the passage?A. The Gregorian calendar was created by Gregory XIII.B. Reducing 3 days every three centuries, people perfect the calendar.C. It takes the Earth less than 365 days to go around the Sun.D. The calendar wouldn39。t be balanced if we had a leap year every four years.【答案】D 【解析】細節(jié)理解題。通讀第一段,尤其最后一句“But, what you might not realize is that the maths isn39。t that simple and occasionally we have to wait eight years”可知,每四年有一閏年是錯誤的,有時候我們得等8年。后文具體介紹了其中的原因,故D項的表述正確。13. What is the purpose of the second paragraph?A. To show the history of the oldest calendar.B. To introduce Gregory XIII to the readers.C. To present how Gregorian calendar was named.D. To indicate that calculation of the leap year is not easy.【答案】D 【解析】寫作意圖題。根據(jù)第二段第一句The method of calculating when leap years occur might be a bit more plicated than you think和最后一句The people who created it realized it wasn39。t perfect to just add an extra day every four years”可知,確定什么時候是國年的計算過程可能比想象的更復(fù)雜,每四年增加一天的計算方法并不完美。后文具體介紹了如何確定什么時候是閩年的計算方法。由此推斷第二段的作用是表明國年的計算并不容易,故選擇D項。14. Which of the following will be a leap year?. B. 2400. C. 2700. .【答案】B 【解析】推理判斷題。根據(jù)最后兩段中every turn of a century should skip the extra day to subtract those three extra days和So, every 400 years the turn of the century is a leap year”可知,閏年的計算方法是在每四年閏一天的基礎(chǔ)上,每到世紀之交時不閏這一天,而每400年要再閏一天。根據(jù)”The year 2000, the millennium, is a leap year”可知2000年是閏年,400年之后的2400年應(yīng)該是閏年,故選擇B項。15. In which section is the text most likely to appear?A. A news report. B. A geography textbook.C. A science magazine. D. An astronomy book. 【答案】C 【解析】推理判斷題。本文講述了為什么閏年不是每四年一次并詳細介紹了如何計算哪一年是閏年,哪一年不是閏年的方法。這類與科學計算有關(guān)的內(nèi)容最有可能出現(xiàn)在科學雜志上,故選擇C項。第二節(jié) (共5小題；，) 根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。Exploring work possibilities is quite an emotional challenge for people The desire to simplify the process by focusing on one attractive option,instead of keeping your eyes open for even more possibilities, can be very ,we39。d rather make a decision in a However, putting off a decision until after you have done your detective work can make you pay a price in ways you can39。t even imagine now.
