Unit 6 Section B 3a-Self check分层作业答案与详解
一、用所给单词的正确形式填空
1．Last year vegetables (grow) in the garden by Tom and he (sell) them himself.
【答案】were grown sold
【详解】句意：去年蔬菜是在花园里被汤姆种植，他自己销售了它们。蔬菜肯定是“被种植的”，所以需要使用被动语态，“被种植”这个动作肯定是发生在过去，所以需要使用一般过去时的被动语态was/were done，主语是vegetables，是第三人称复数主语，所以对应的be动词选用were，动词grow的过去分词是grown，后半句是在描述过去的一个动作，用一般过去时即可，表示“过去销售”，sell的过去式形式是sold，故填 were grown和 sold。
2．The spaceship used to be (control) by astronauts.
【答案】controlled
【详解】句意：这艘宇宙飞船过去由宇航员控制。此句主语The spaceship“宇宙飞船”与动词control“控制”之间是被动关系，被动语态结构是be+done，control的过去分词是controlled。故填controlled。
3．Their team (name) Stars of Victory to hope for success.
【答案】was named
【详解】句意：他们的球队被命名为“胜利之星”，希望获得成功。Their team和name构成被动关系，所以此处应用被动语态，表示“被命名”。根据语境可知，此处时态为一般过去时。故填was named。
4．Remember (lock) the door when you go out.
【答案】to lock
【详解】句意：出门时记得锁门。根据“Remember”可知，Remember to do“记得去做”，故填to lock。
5．A knife is (use) for (cut) things.
【答案】 used cutting
【详解】句意：刀是用来切东西的。use v.使用；cut v.切。固定句型：be used for doing“用于做……”，故填used；cutting。
二、单项选择
6．Soccer is a wonderful game for children. 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.
A．remind B．remain C．represent D．record
【答案】B
【详解】句意：课后我们不允许在教室里待太久。
考查动词辨析。remind提醒；remain保持，继续存在；represent代表；record记录；根据“in the classroom after class for too long.”可知，此处指“逗留在教室里”，用remain，故选B。
