 www.ks5u.comPeriod 6　Language Focusing

The General Idea of This Period

This is the sixth period of this unit. In this unit, we will mainly deal with the language points in the material that we have learnt, including some words, phrases and sentence patterns. Because we have talked about, read and to the material, and the students are already familiar with them. The aims of this class are to let the students know the usage of these words, phrases and sentence patterns; help the students to use them correctly and finish some exercises about the words, phrases and sentence patterns. First check their homework. Secondly, present the usage of the words, phrases and sentence patterns. In order to have a deep impression on them, you can ask the students to find them in the context and underline them, because on one hand, they have learnt them; on the other hand, that will help to develop the students’ ability of learning by themselves. To make them more familiar with the words, phrases and sentence patterns, the teacher can give them more practice, both oral and written. Meanwhile, the teacher will help them to make up sentences, to improve their ability of using the language and imagination. As to consolidation, the students are supposed to make sentences by themselves, using the new words and phrases in this unit. At last, they are asked to finish some of the exercises on Page 4 and Page 42 and Page 43 as their homework.

1.他对养狗提出了一个新的观点。

2.我们提议周末去郊游.

她把报纸放下, 拿起了一本书。

He asked me about the new book. I happened to know about it

他向我问起那本新书, 正巧我了解它的一些情况。

T: Quite good. And how to say“证明”？

1)Can you prove it to me?

你能向我证实吗？

2) I shall prove to you that what I said is the truth.　

我将向你证明我所说的是真话。

It also means “be seen or found to be something”; “turn out to be something”.

It is always followed by“(to be)+adj.” or “that clause”.

For example: 

1)The task proved (to be) more difficult than we had thought.

这项任务原来比我们预想的难得多。

2)He proved himself (to be) a very good driver.

他的表现说明他是一个很好的司机。

T: Are you clear?

(Teacher shows the following on the blackboard.)

1. John Snow once a__________ Queen Victoria to e__________ the birth of her babies.

Suggested answers:

1.attended, ease　2.exposed　3.absorb　4.blame　5.In addition, linked to6.prevent it from happening again, suggested　7.make sense　8.rejected

T: You should know very well about these words and phrases. Let’s deal with them one by one. What does “attend” here mean?

S: It means “照顾”.

T: Yes. It means “take care of” .For example: 

The nurse who attends the old man is very patient.

看护那位老人的护士非常有耐心。

T: What other meanings do you know about it?

S: It can also mean “be present”.

Only a few friends attended their wedding.

只有几个朋友参加了他们的婚礼。

T: Thank you. You are very clever. The phrase “attend to” means “give practical consideration to”. For example: 

There are 50 students for me to attend to.

我要关照50 名学生。

T: Who’d like to say something about “ease”?

S: It means “relieve from pain, anxiety, discomfort”.

T: Can you give us some examples to help us remember this word?

S: OK.

1) Talking eased his anxiety.

那一番谈话打消了他的顾虑。　

2) The medicine eased my headache.

这药使我头痛减轻。

T: Excellent. The phrase “at ease” means comfortable and unworried; completely relaxed.

I never feel at ease in his company.

我跟他在一起总是感到很不自在。

They were all so kind and friendly that I felt completely at ease.

他们每一个都和蔼可亲, 使我一点也不拘束。

T: And how about this one “Tom is so strong that he can lift the stone with ease.”

Ss: 汤姆身体很强壮, 能轻易地举起那块石头。

T: So here “with ease” means “without any difficulty”. Right? Then let’s talk about the word “expose”. It means “uncover, leave uncovered or unprotected”. It is often used with “to”. So how can we say 使皮肤暴露于阳光下?

Ss: Expose one’s skin to the sun.

T: What’s the Chinese meaning of Sentence 4?

Ss: 哪个司机该负责？

T: Pay attention, the phrase “be to blame” means“ be responsible for sth. bad”, “deserve to be blamed”. We should use the active voice. Another example: 

谁该为这次火灾负责？Who can translate this sentence?

S: Who is to blame for the fire?

T: Besides, we have “blame sb. for sth.”, “blame sth. on sb.”

1) They blamed him for the accident.

他们为这起事故而责怪他.

2) They blamed the accident on him.

他们把这起事故归咎于他。

T: “in addition (to)”means as an extra person, thing or circumstance. Put the following sentences into Chinese.

In addition (to the names on the list) there are six other applicants.

In addition, we also bought many books for the children in the poor area.

Suggested answers:

除此（名单上的名字）之外还有六个申请人。

此外我们还给贫困地区的孩子们买了很多书。

T: What does “link to” mean?

Ss: 把……与……连接起来, 联系

T: Who’d like to give us the Chinese meaning of “Fingerprints linked the suspect to the crime.”

S: 指纹证实了嫌疑犯的犯罪行为。

T: “suggest”means 1) put sb./sth. forward for consideration 

2 ) propose sth. to sb.

3) put an idea into sb.’s mind 

For example: 

I wrote suggesting that he should come for the weekend.

我写信请他来度周末。

I suggested to him that we should start earlier.

我向他建议我们早点动身。

His words suggested that he was angry.

他的话表明他生气了。

(When“suggest”means 建议, we should use subjunctive mood in“that clause”)

T: “make sense”means“have an understandable meaning”.Please translate my sentences:

1)你的话没有道理。

2)这些词藻堆砌在一起讲不通。

Answers: 1) What you say makes no sense.

2) These words are jumbled up and don’t make sense.

T: And we have the phrase “make sense of sth.” which means 理解或弄懂困难的事物.

T: ...

Step  4 Learning some sentence structures

T: Now let’s learn some sentence structures. Can you find the sentence in the passage? Can you translate it into Chinese? But he became inspired when he thought about helping ordinary people exposed to cholera.

S: 一想到要帮助那些受到霍乱威胁的普通百姓, 他就感到很振奋。

T: Can you help me to analyze this sentence?

S: Let me have a try. In this sentence, the subject is “he”, the predicate is “became inspired”.“when clause”is an adverbial clause for time. In this adverbial clause, “exposed to cholera” is used as the attribute.

T: Well done. You should pay special attention to the word “exposed” in this sentence. It is used as an attribute. Are you clear?

Ss: Yes.

T: In the sentence “So many thousands of terrified people died every time there was an outbreak.”, Can you explain “every time” to us?

S: every time在这起一个从属连词的作用, 后面接从句。类似的短语还有each time, the moment, the minute等等。如: 

1) I will write to you the moment I get to Beijing.

2) The old woman couldn’t help crying each time she thought of her son who died in the battle.

T: Then look at this sentence “He got interested in two theories explaining how cholera killed people.” Why should we use “explaining” here?

S: It is also used as an attribute. We can change this sentence into another form: He got interested in two theories which explained how cholera killed people.

T: How about this sentence “Only if you put the sun there did the movements of the other planets in the sky make sense.”

S: 这句话的意思是: 只有当你把太阳放在中心位置上, 天空中其他行星的运动才能说得清楚。这是一句倒装句。因为only从句放在句首, 句子要用部分倒装结构。

T: Can you give us more examples?

S: Only by studying hard can we learn English well.

Step 5 Consolidation

T: We have just learned some words, phrases and some sentence structures. Do you have any other difficulties? Now look through the passages to understand more and find out your own puzzles.

(The students should be allowed to read the passages, while the teacher had better give them individual help if necessary. If there are some common problems, the teacher should explain them in the whole class.)

T: If you haven’t any problems, let’s have a competition. You can choose any of the words or phrases we learned to make up some sentences. For each sentence, I will give you ten marks. The more, the better. Now, let’s begin.

Ss: ...

(Finally the teacher should sing highly of the winner, and encourage the others to work hard to succeed next time.)

Step 6 Homework

T: After class, please go over what we have learned today and make up a story in which you had better try to use as many new words and phrases in this unit as possible. Then finish the exercises on Page 4, Page 42 and Page 43.
