A．If B．Although C．Until D．So that 【答案】B 【详解】句意：尽管外面很冷，他仍然每天出去锻炼。 If如果；Although虽然，尽管；Until直到；So that以便。“外面很冷”和“他仍然每天出去锻炼”存在让步转折关系，用Although引导让步状语从句。 5.I didn’t realize my fault ________ my teacher pointed it out to me.

A．why we don’t need to take medicine B．that we should be positive C．when should we smile at life D．how can we stay healthy 【答案】B 【详解】句意：俗语“笑是最好的良药”向我们展示我们应该保持积极。 考查宾语从句的语序和句意理解。why we don’t need to take medicine为什么我们不需要吃药；that we should be positive我们应该保持积极；when should we smile at life我们何时应该笑对生活，语序错误；how can we stay healthy我们如何能保持健康，语序错误。宾语从句需用陈述语序，C、D选项为疑问语序，排除。再结合俗语“笑是最好的良药”的含义，强调乐观积极的态度对身心健康有益，而非否定吃药或直接说明具体方法。故选B。 10.We should do what we can ________ the hunters from ________ the animals.

As I walked around the campus, my attention 61 by a classmate. He was carrying a big bag. The bag was so heavy that he couldn’t hold it. Looking a bit worried, he came up to me and asked 62 help. I offered my hand at once. He smiled brightly and thanked me right away. One week later, we started 63 military training (军训). We had to reach the playground by 6:30 am daily. One morning, I was still asleep at 6:20. That classmate woke me up. 64 , none of us was late for that day’s training. From then on, we became close friends. Over the next four years, we helped each other often, but we almost never said “thank you”. I always felt thankful when I received help. But I was often too 65 to say it aloud. I thought everyone had 66 same feeling as me. After I started to work, however, my attitude towards thanks changed. A “thank you” is often just a polite ending for a conversation. It also makes the office a lovelier place. I suddenly realized that I 67 thank my old friend and I did it right away. At first, he was surprised to hear my thanks on the phone, 68 later we talked and laughed over time. It seems that both of 69 got much closer than ever before. 70 powerful word “thanks” is! Whenever you feel thankful, just say it. 61．A．catches B．was caught C．is caught 62．A．of B．for C．after 63．A．to receive B．received C．receives 64．A．Lucky B．Luckily C．luck 65．A．shy B．shyer C．shyest 66．A．a B．an C．the 67．A．should B．can C．may 68．A．but B．because C．so 69．A．we B．our C．us 70．A．What B．What a C．How 【答案】 61．B 62．B 63．A 64．B 65．A 66．C 67．A 68．A 69．C 70．B 【导语】本文讲述了作者大学受助却羞于道谢，工作后主动致谢，让友谊升温的故事，传递了“感谢要勇敢说出口”的主题。 61．句意：当我在校园里闲逛时，我的注意力被一位同学吸引了。 全文为过去时态，attention“注意力”与catch“吸引”是被动关系，需用一般过去时的被动语态was caught。 62．句意：他看起来有点着急，走过来向我求助。 固定搭配ask for help表示“请求帮助”，因此选介词for。 63．句意：一周后，我们开始接受军训。 固定搭配start to do sth.表示“开始做某事”，因此用不定式to receive。 64．句意：幸运的是，那天的军训我们没有一个人迟到。 此处需副词修饰整个句子，故选副词Luckily。Lucky是形容词，luck是名词，二者词性均不符合要求。 65．句意：但我常常太害羞了，不敢大声说出来。 “too…to…”结构中，中间需用形容词原级，因此选shy害羞的。shyer是比较级，shyest是最高级，均不符合原级使用规则。 66．句意：我以为每个人都和我有同样的感觉。 形容词same前必须加定冠词the，为固定用法。 67．句意：我突然意识到我应该感谢我的老朋友，于是我立刻就做了。 语境表示“我意识到应该感谢老朋友”，should“应该”符合文意。can表示能力，may表示许可，二者语气较弱，不符合语境。 68．句意：起初，他在电话里听到我的感谢很惊讶，但后来我们渐渐地聊起来，也不时大笑。 前半句“惊讶”与后半句“聊得开心”是转折关系，用but“但是”连接。because表示原因，so表示结果，二者逻辑关系不符。 69．句意：似乎我们俩比以前更亲密了。 介词of后面要用人称代词的宾格形式，因此选us“我们”。we是主格形式，our是形容词性物主代词，二者词性均不符合要求。 70．句意：“谢谢”这个词多么有力量啊！ 感叹句修饰可数名词单数word，结构为“What a+形容词+名词!”，因此选What a。What通常修饰复数或不可数名词，How通常修饰形容词或副词，二者结构不符。 第三篇： Staying healthy is very important for everyone, especially for teenagers who are growing up. A healthy body can help us study better and live a happier life. Here are some suggestions for us 71 healthy. First, we need to have a balanced diet (均衡饮食). We should eat more fruit and vegetables every day. They are rich in vitamins and fiber (纤维) 72 are good for our bodies. We shouldn’t eat too much junk food, like hamburgers and French fries.
