I even felt a little smarter …I felt a sense of acplishment…I felt my waist got smaller and my arms got stronger, and I no longer felt guilty after having a piece of cake or a drink.”可知，在鍛煉的最后我頭痛少了，精力充沛了，而且更快樂。因此可以推斷出and后面的內(nèi)容是“不想再鍛煉下去”，故選A?！?由“However, finally I overcame that negative thought and kept working out.”可知，然而我終于克服了這種消極的想法繼續(xù)鍛煉。 （3）考查詞義猜測。因此該段的主要內(nèi)容是作者堅持鍛煉計劃的困難。根據(jù)第二段中的“It was easy to promise on paper, but three weeks of remended exercise routines and diet restrictions wouldn39。故選C。s 21day workout challenge”可知，昨晚我做了一個錯誤的決定：吃了一頓大餐。根據(jù)第一段中的“As I was burning off last night39。最后，鍛煉給作者帶來了好心情。s more important to see what he likes than just feel it. was no need to feel guilty about things he disliked to do.【答案】 （1）C（2）D（3）A（4）B 【解析】【分析】本文是一篇記敘文，一張宣傳健身鍛煉的海報讓作者開始馬拉松的熱身。s killing his spare time. importance of sticking to the normal daily routine. difficulty of the author39。Stopping being lazy for a change.（2）What is paragraph 2 mainly about? of the author39。Eating a lot the previous night.B.s wrong decision? A.At the end of the challenge, I learned something even more important: Feeling the results is better than seeing them. I had fewer headaches and more energy, and was simply happier. I even felt a little smarter as I researched which foods were better for my body, and learned how to make healthier meals.

But the difficult part about making a challenge is realizing that wanting and doing are two very different things. Just like a career, you have to physically work for it rather than just wait for it to happen. But that39。t be easy.

These returning fish, are crucial for coral reefs to function as healthy ecosystems. Boosting fish populations in this way could help to kickstart natural recovery processes, preventing the damage we39。Healthy coral reefs are remarkably noisy placesthe crackle of snapping shrimp and the whoops and grunts of fish. Young fish concentrate on these sounds when they39。 Coral reefs (珊瑚礁) are an integral part of sea life and sustain it by providing shelter and habitat to various organisms. They also supply and recycle nutrients as well as enable a growing fish population, along with other species, for a healthy and diverse ecosystem. However, the rise in average water temperatures due to climate change has resulted in more frequent and longtime coral bleaching (白化現(xiàn)象) events that damage their health, causing fish and other sea species to abandon them. 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科技類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。根據(jù)最后一段中的“Baidu made an early bet on AI, and is leading its rivals in autonomous driving.”可知百度在無人駕駛汽車的故選C。 （3）考查細節(jié)理解。根據(jù)第四段“In the test, panies subjected their artificial intelligence systems to queries from the Stanford Question Answering Dataset, which assessed reading prehension.
