Duty report / 3-minute speech. (say something about your favourite color ).Step 2. Presentation：Object clauses introduced by that An object clause functions as the object of a sentence. We use that to introduce an object clause that is a statement.An object clause can be put after verbs such as say, find, know, think, believe, hope, notice and meane.g. Some people believe that colours can influence our moods.She hopes that yellow can bring her successAn object clause can also follow adjectives such as certain, sure and glad.e.g. He is glad that the walls in his room are blue.She is sure that yellow can bring her good luck.In informal English we often drop thate.g. I think (that) blue is better than pink.“Im feeling blue” means (that) “Im feeling sad”.Do you think (that) your favourite colour matches your characteristics?Step3 Working out the rules 1. We can use that clause to replace an object after the verb in a sentence. 2. The word order in the object clause is just the same as that in the statement. 3. Sometimes we can leave “that” out in the object clause.Step4 Extension 1. When the main clause uses the simple present tense or future tense, the object clause still uses the original tense.e.g. I dont think (that) you are right.2. When the main clause uses the simple past tense, the tense in the object clause should be changed into the corresponding past tense.e.g. He told me (that) he would go back home soon. 一般现在时 现在进行时 一般过去时 现在完成时 一般将来时 3. When the object clause is used to express the objective facts, truths, proverbs or natural phenomena, we still use the original tense.e.g. My grandpa told me (that) the earth is round.

Such an object clause often follows verbs such as ask, see, wonder and find out. The word order in the clause should be the same as that in a statement. e.g. You may wonder if/whether colours influence our moods.Sandy asks if/whether orange can cheer her up.Step9 Practice （语序，时态，连接词）( )1.
