Throughout the day your brain rarely gets a chance to stop and think. It constantly responds to a stream of challenges, from writing a report for a work deadline to remembering where you left your car keys and figuring out what to buy for dinner.

At the end of last semester(學(xué)期), my adviser told me the two classes I had chosen for this semester took place during the same period, which meant that I had to give up one of them. She remended that I take the course called life management. I had never heard of that kind of course in China so I just followed her advice. In fact, students are able to change classes within the first month of the semester. During that month, there39。 After the first week, I looked through courses that were available for me. I had two choices: biology and chemistry. Chemistry is for college students who would like a collection of degrees in one specific area after high school.

However sometimes they cannot take the course they want to take due to different reasons like schedule conflicts.（與大多數(shù)中國高中生不同的是，加拿大的高年級學(xué)生可以自己選擇他們想學(xué)的課程。）可知，本文講述的是學(xué)生對課程的選擇可能很難。 【點評】考查閱讀理解。細(xì)節(jié)理解題把握題干關(guān)鍵詞，在原文查找依據(jù)。主旨大意題把握首段尾段，尤其是首段轉(zhuǎn)折處。 By the time you read these words, winter should have gone within the Northern Hemisphere (半球). But at its worst, this winter was unusually cold. Here in New York City on January 31, the low temperature dropped to 17℃. In Chicago, it was also 17℃—but that was the high. The low jumped to 29℃. And the wind chill within the Windy City was 44℃ or 46℃, relying on which climate station was crying out in pain. As ic Lewis Black said, That is not weather. That39。 When the forecast warned us a few days earlier that Arctic air was looming (陰森地逼近), President Trump issued a sincere and helpful tweet, which ended with: What the hell is going on with Global Warming? Please e back fast, we need you! And being the most powerful man on Earth, he was successful in his polite request. On February 4 the Chicago temperature reached 11℃. And the following day the Big Apple was in a sunny 19℃. Like so much else we are currently living through, this experience is not normal.

In Chicago, it was also 17176。C. And the wind chill within the Windy City was 44℃ or 46℃可知天氣情況極其惡劣。故答案為A。根據(jù)第三段But less than a week later, thanks to some warm air ing up from real south, I was walking outside without a coat on a date when the temperature in Chicago因此真正的原因是南方傳來的暖氣。故答案為C。根據(jù)第五段原文，文中這個詞出現(xiàn)在Well, yes.
