It ________ great exercise, such as running and kicking. A．provides B．remains C．practices D．receives 【答案】A 【详解】句意：对孩子们来说足球是一种精彩的游戏。它提供了很好的锻炼，比如跑步和踢。 考查动词辨析。provides提供，供给，供应；remains仍然是，保持，留下；practises实习，练习；receives接到，接待，收到，接受。根据“Soccer is a wonderful game for children. It...great exercise, such as running and kicking.”。可知，它提供了很好的锻炼，比如跑步和踢。故选A。 7．The method of making gunpowder ________ the Europe in the 14th century. A．is bringing to B．was bringing to C．was brought to D．were brought to 【答案】C 【详解】句意：制造火药的方法是在14世纪传到欧洲的。 考查被动语态。主语“The method of making gunpowder”与动词bring存在被动关系，且根据“in the 14th century”判断时态为一般过去时，故此处要用一般过去时的被动语态，结构为was/were done；主语“The method of making gunpowder”为单数，故应用was。故选C。 8．Many bridges and houses ________ in the flood last month. A．is destroyed B．are destroyed C．was destroyed D．were destroyed 【答案】D 【详解】句意：上个月许多桥梁和房子在洪水中被毁坏了。 考查一般过去时的被动语态。根据“last month”可知应用一般过去时，而主语Many bridges and houses和谓语动词destroy“毁坏”是逻辑上的动宾关系，应用被动语态，而一般过去时的被动语态的谓语结构为“was/were+done”，主语不是第三人称单数，be动词应用were，故选D。 9．— I watched a movie last night. It lasted ________ three hours. — That’s really too long. A．normally B．suddenly C．especially D．nearly 【答案】D 【详解】句意：——我昨晚看了一场电影。它持续差不多三小时。——那真的太长了。 考查副词辨析。normally正常地；suddenly突然地；especially尤其；nearly几乎，差不多。根据“It lasted...three hours.”可知，此处指电影持续差不多三小时。故选D。 10．We are not allowed to ________ in the classroom after class for too long.
