 名词性从句包括主语从句、宾语从句、表语从句和同位语从句。在复合句中充当表语的从句称为表语从句，一般位于系动词(be、look、remain、seem等)之后。这种从句往往是对主句的主语的进一步解释说明。 引导表语从句的词有： 连接词 that、whether、as if/though、because等 连接代词 what、who、whom、whose、which、whatever等 连接副词 when、where、how、why等 1.that和whether引导表语从句 that引导表语从句时仅起连接作用，无任何意义，在从句中不作任何成分，但通常不可省略。whether引导表语从句时起连接作用，意为“是否”，在从句中不作任何成分。注意：if不能引导表语从句。 *What he wants to know is whether Mrs. Smith can help polish his composition. 他想知道的是Smith夫人是否能帮他润色作文。 *The reason why some time-honoured brands have survived fierce competition is that they are willing to take on challenges. 一些老字号之所以能够在激烈的竞争中生存下来是因为它们愿意接受挑战。 2．连接代词引导表语从句 连接代词what、who、whom、which、whose等引导表语从句时，除了在句中起连接作用外，还在从句中作主语、宾语、表语或定语等成分。 *The country is becoming stronger and stronger.It is no longer what it used to be. 这个国家正变得越来越强大。不再是过去的样子了。 *The problem is who can complete the difficult task within two days. 问题是谁能在两天之内完成这项困难的任务。 3．连接副词引导表语从句 连接副词when、where、how、why等引导表语从句时，除在句中起连接作用外，还在从句中分别充当时间、地点、方式、原因等状语。 *This is where we usually think it's easier to just give up. 这就是我们通常认为更容易放弃的地方。 *The best moment for the football star was when he scored the winning goal. 对这名足球明星来说，最美好的时刻就是他踢进制胜球的时候。 *The problem is how the part is made to serve the present and foreign things are made to serve China. 问题在于如何做到古为今用，洋为中用。 4．as if/though引导表语从句 as if/though引导的表语从句常置于 look、seem、sound、be、become 等系动词后面。as if/though引导的表语从句如果描述的是事实或极有可能发生的情况，则从句用陈述语气；如果描述的是非真实的情况，则从句用虚拟语气(表示与现在事实相反时，从句动词用一般过去时；表示与过去事实相反时，从句动词用过去完成时；表示与将来事实相反时，从句动词用would/could/might＋动词原形)。 *When a pencil is partly in a glass of water, it looks as if it were broken. 当把铅笔的一部分放在一杯水里时，它看起来好像断了。 *The thick smog covered the whole city.It was as if a great black blanket had been thrown over it. 浓烟笼罩了整个城市，好像把一块大黑毯盖到了它的上面。 5．三个易混的表语从句 (1)“This/That/It is why＋表语从句(表示结果)”意为“这/那就是……的原因”； (2)“This/That/It is because＋表语从句(表示原因)”意为“这/那是因为……”； (3)“The reason why...is that＋表语从句”意为“……的原因是……”。 *It is reported that a huge percentage of bird species are in danger.It's because their habitats or homelands are disappearing. 据报道，大部分鸟类正处于危险中。这是因为它们的栖息地或家园正在消失。 *She has a baby to take care of.That's why she often comes late. 她有一个孩子需要照顾。那就是她经常迟到的原因。 *The reason why she often comes late is that she has a baby to take care of. 她经常迟到的原因是她有一个孩子需要照顾。 关键能力 互动探究 词汇精研 1.trial n．试验；试用；审判vt.测试(能力、质量、性能等)；试验；试用 [教材原文] ...Ruth managed

Jackson Hedden is an advocate of creative minds and creative ideas.He believes that every person is born creative but loses their creativity as they mature.This results in completely boring personalities and a lack of creative problem-solving techniques.According to Jackson, the most significant way to find personal success is to allow creativity to shine through all ideas coming to life. It is important to build a connection with anything one is working on.It is a common human characteristic that people tend to react to situations better if they have had a personal experience with them.This enables them to understand the problem better, resulting in more unique and innovative solutions to solve it.Following a similar approach, Jackson also establishes a connection with the products he is designing so that he can better understand the improvements he can bring to the existing design. Jackson made his debut (首次露面)as an industrial designer in 2017 and worked with Karim Rashid, a New York-based industrial designer.This was his first exposure to the design industry, and Jackson learned a great deal.As this was just the beginning of his career, Jackson wished to explore more, so he worked together with the founder of Kabaq and the CEO of Alper Guler to become the exclusive designer for an augmented food reality startup.He then joined a Los Angeles-based firm, RKS Designs, and worked there for a period of two years. Keeping up with the trends, Jackson's designs are clean, innovative, and elegant.He has always kept himself in his customers' shoes and designed the product according to their convenience. Having a keen interest in designs and creative works, Jackson is always interested in a challenge to build something new with his extraordinary design techniques.
