(P21)Do you know后面跟的是一个由疑问代词how many引导的宾语从句。在英语中，特殊疑问词引导的从句作为宾语从句时，宾语从句中应用陈述句语序。如：Do you know where the train station is? 你知道火车站在什么地方?Can you tell me how many people there are in Class 1，Grade 9?你能告诉我九年级一班有多少人吗?2This article explains what colours can do and what characteristics they represent(P22)句中what colours can do和what characteristics they represent并列作explains的宾语；they represent是定语从句，修饰先行词characteristics，关系代词that或which已省略。如： Could you tell me what we shoulddo before the coming examination?你能告诉我考前我们应该做些什么吗?At the new supermarket you can choose anything(that)you need在那家新超市里你可以选择你所需要的任何东西。3Wearing red can also make it easier to take action(P23)句中的wearing red是动词一ing形式，用作主语。it为形式宾语，指代真正的宾语to take action，easier是宾语补足语。make+npron十adj，意为“使怎么样”。如： You will find it difficult to work out the Maths problem你会发现很难算出这道数学题。 Too much work made the workers unhappy工作太多使工人们不开心。4This may help when you are having difficultymaking a decision(P23) 旬中的have difficulty(in)doing something意为“做某事有困难”，相当于have difficulty with something。类似的还有：have troubleproblems(in)doing something，相当于have troubleproblems with something。如：Do you have difficulty(in)solving this Maths problem?你解决这个数学题有困难吗?Maybe you have difficultytroubleproblems(in)making friends 或许你在交友上有困难。这里的make a decision意为“做决定”，是个固定短语，其中的decision是decide的名词形式。如：Have you made a decision? 你已经做出决定了吗? He made a decision to go camping他做出了去野营的决定。【语法点拨】宾语从句(一)1that引导的宾语从句(1)that在宾语从旬中只起连接作用，并不作句子成分，其本身也没有实际意义，在口语或非正式文体中常常省略。如：She told me(that) she could finish it herself 她跟我说她可以自己完成。(2)that引导的宾语从句，其主句的谓语动词多为know，think，believe，hope，mean；也可用于主句形容词之后，如：Certain，sure，glad，afraid，sorry等。如：He thinks that he can go swimming tomorrow 他认为他明天能去游泳。 I am glad that you can come for dinner.我很高兴你能来吃晚饭。2if或whether引导的宾语从句(1)if或whether可引导宾语从句，此时从句部分的语义相当于一个一般疑问句。如：I want to know ifwhether he is our new teacher,我想知道他是不是我们的新老师。(2)连词if和whether意为“是否”，在从句中不充当句子成分，在口语中多用if如：Tom wonders ifwhether his grandpa will come next week汤姆想知道他的爷爷是否下周过来。
