語法探究構(gòu)詞法就是利用詞形變化的規(guī)律來構(gòu)成詞匯的方法。英語構(gòu)詞法主要有三種：合成、派生和轉(zhuǎn)化。本單元我們先了解一下合成法。合成法把兩個(gè)或兩個(gè)以上的詞合在一起而構(gòu)成一個(gè)新詞，這種構(gòu)詞法稱為合成法。新詞的詞義往往是在合成它的詞的詞義上產(chǎn)生。(1)合成名詞black＋board→blackboard黑板(形容詞＋名詞)單元語法聚焦

day＋break→daybreak黎明(名詞＋名詞)hand＋writing→handwriting書法(名詞＋動(dòng)名詞)type＋writer→typewriter打字機(jī)(動(dòng)詞＋名詞)after＋noon→afternoon下午(介詞＋名詞)

語法探究由一個(gè)主句和一個(gè)或一個(gè)以上的從句構(gòu)成的句子叫作復(fù)合句。在復(fù)合句中用來修飾主句中的謂語動(dòng)詞、形容詞或者副詞等的從句稱為狀語從句。狀語從句從其表達(dá)的含義來看，可分為條件、時(shí)間、原因、比較、結(jié)果、目的、讓步、方式、地點(diǎn)狀語從句。本單元重點(diǎn)講解if引導(dǎo)的條件狀語從句。if引導(dǎo)的從句在復(fù)合句中表示條件，我們稱之為if引導(dǎo)的條件狀語從句。if引導(dǎo)的條件狀語從句既可以放在主句________，也可以單元語法聚焦之前

放在主句________，當(dāng)放在主句之前時(shí)，從句后面要用________與主句隔開。if引導(dǎo)的條件狀語從句的時(shí)態(tài)1.if引導(dǎo)的條件狀語從句的時(shí)態(tài)要與主句保持_______，若主句是一般將來時(shí)，從句則用__________表示將來。例如：IfIamfreetomorrow,IwillgotoBeijing.如果我明天有空的話，我就去北京。2.如果主句含有________，如can,may,must,need等，從句要用一般現(xiàn)在時(shí)。例如：?jiǎn)卧Z法聚焦之后逗號(hào)一致一般現(xiàn)在時(shí)情態(tài)動(dòng)詞
