He is ________ (write) a letter. 【答案】 isn’t writing 【详解】句意：——鲍勃在做作业吗？——不，他不是。他正在写信。根据“Is Bob doing homework?”以及答语“No, he…”可知，句子是以“Is Bob”开头的一般疑问句，此处作否定回答，应表达为“No, he isn’t”；根据“He is…a letter.”可知，句子时态为现在进行时，其结构为“be doing”，空前为is，空处应用write的现在分词形式。故填isn’t；writing。 93．The boy was so lucky that he was still ________(live) after falling from the seventh floor. 【答案】alive 【详解】句意：这个男孩太幸运了以至于他从七楼落下去依然活着。此空应填形容词和he was构成主系表结构，提示词live可变成alive意为“活着的”，符合语境。故填alive。 94．There was a storm yesterday. Luckily, most of the flowers in my garden are still ________ (live). 【答案】alive 【详解】句意：昨天下了一场暴风雨。幸运的是，我花园里的大部分花都还活着。根据“Luckily”可知，此处是说大部分花活着，应用形容词alive，意为“活着的”。故填alive。 95．The kind woman always helps the ________ (home) children. 【答案】homeless 【详解】句意：这个善良的女人总是帮助无家可归的孩子们。根据“always helps the...children”及提示词可知，此处指无家可归的孩子；homeless“无家可归的”，形容词作定语。故填homeless。 96．The farmers used a _________ to kill the insects. (chemistry) 【答案】chemical 【详解】句意：农民们使用一种化学药品来杀死昆虫。根据“The farmers used a...to kill the insects”可知，此处是指化学药品，chemical“化学药品”，a后面加名词单数。故填chemical。 97．To my ________ (disappoint), my father doesn’t agree to buy me a new bike. 【答案】disappointment 【详解】句意：令我失望的是，我父亲不同意给我买一辆新自行车。disappoint“使……失望”。根据“To my”可知，空格处应用名词形式，即disappointment“失望”，不可数名词。故填disappointment。 98．They ________ (not find) any new species since they ________ (arrive) here. 【答案】 haven’t found arrived 【详解】句意：自从他们到这里以来，他们还没有发现任何新物种。find“发现”，根据时间状语“since they...here”可知，主句需用现在完成时，从句用一般过去时，主句主语“They”是复数，助动词用have，和not缩写为haven’t，find变为found；arrive“到达”，其过去式为arrived。故填haven’t found；arrived。 99．To his ________, his team didn’t win the first prize in the game. (disappoint) 【答案】disappointment 【详解】句意：令他失望的是，他的球队在比赛中没有获得一等奖。形容词性物主代词后加名词disappointment“失望”，不可数名词。故填disappointment。 100．The book ________ (sell) well since it ________ (come) out last month. 【答案】 has sold came 【详解】句意：这本书自上个月出版以来一直很畅销。“sell”表示“销售”，是不及物动词，没有被动语态。根据“since it...out last month”可知，since引导的时间状语从句用一般过去时，“come”的过去式是“came”；主句要用现在完成时，其结构为“have/has + 过去分词”，主语“The book”是单数，用“has”，“sell”的过去分词是“sold”。故填has sold；came。 1 / 1乐思英语 学科网（北京）股份有限公司 $考前特训 单句语法填空—易错特训100题（外研版） 八年级下册(Units 4-5) 考前复习之重点单词全掌握 班级 姓名 学号 分数 （时间：45分钟；每小题1分，满分：100分） 填空题：在空格处填入1个合适的词或用所给单词的正确形式填空 1．This kind of ___________ (virus) spreads quickly in winter. 2．I believe that victory ___________ (belong) to those who work hard and never give up. 3．The teacher told us ___________ (not play) with fire. 4．Mary was ___________ (serious) injured in the accident and had to be in hospital. 5．Thank you for ___________ (volunteer) to help us. 6．Wang Rui _________ (look) into the animal world when she was young. 7．The ___________ (sunshine) makes the community garden beautiful. 8．____________ (accord) to the report, the environment of this area has improved a lot. 9．With the help of her family, Leah was able to ___________ (raise) enough money for the hospital. 10．She kept ___________ (practice) speaking English. 11．Let’s ___________ (do) our best to support the team. 12．Trees ___________ (general) grow taller and stronger with enough sunlight and water. 13．We should ___________ (offer) help to people in need. 14．Is there ___________ (somebody) who can help me with this math problem? 15．Excuse ___________ (I).
