The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.

小學(xué)數(shù)學(xué)人教版三年級(jí)下冊(cè)《簡(jiǎn)單的小數(shù)加、減法》說(shuō)課稿
一、說(shuō)教材 在學(xué)習(xí)本課前，學(xué)生對(duì)筆算整數(shù)加減法已經(jīng)熟練掌握，并且以元、角、分等常用計(jì)量單位的知識(shí)作為學(xué)習(xí)小數(shù)的形象支撐，已經(jīng)初步認(rèn)識(shí)了小數(shù)，也為學(xué)習(xí)本課做了有力的鋪墊。加、減法結(jié)合元角進(jìn)行教學(xué)，以便于學(xué)生聯(lián)系實(shí)際來(lái)初步學(xué)習(xí)小數(shù)的加減。本節(jié)課內(nèi)容是為以后系統(tǒng)學(xué)習(xí)小數(shù)打下基礎(chǔ)。小數(shù)在生活中應(yīng)用廣泛，是生活的濃縮和提煉，具有現(xiàn)實(shí)的意義，可以迅速達(dá)到學(xué)以致用的目的，有利于學(xué)生體會(huì)處處有數(shù)學(xué)，融生活課堂于一體。數(shù)學(xué)的價(jià)值得到淋漓盡致的體現(xiàn)。根據(jù)本課所處的地位和作用以及學(xué)生的年齡特點(diǎn)，我制定了以下教學(xué)目標(biāo)。

尊敬的各位領(lǐng)導(dǎo)、老師：大家好！我今天說(shuō)課的內(nèi)容是人教版小學(xué)數(shù)學(xué)三年級(jí)下冊(cè)第四單元《兩位數(shù)乘兩位數(shù)的不進(jìn)位筆算》一課，我將從以下幾個(gè)方面對(duì)本課進(jìn)行闡述:一、說(shuō)教材《兩位數(shù)乘兩位數(shù)的不進(jìn)位筆算》是人教版小學(xué)數(shù)學(xué)三年級(jí)下冊(cè)第四單元的教學(xué)內(nèi)容。這部分內(nèi)容是在筆算兩、三位數(shù)乘一位數(shù)的基礎(chǔ)上進(jìn)行教學(xué)的，只是把第二個(gè)因數(shù)擴(kuò)展到了兩位數(shù)。兩位數(shù)乘兩位數(shù)的不進(jìn)位筆算重點(diǎn)要解決的是乘的順序問(wèn)題和第二部分積的書(shū)寫(xiě)位置問(wèn)題，使學(xué)生掌握基本的乘法筆算方法。為學(xué)習(xí)兩位數(shù)乘兩位數(shù)的進(jìn)位筆算、多位數(shù)乘多位數(shù)的筆算打基礎(chǔ)。因此，本課是是本單元的重點(diǎn)，對(duì)今后進(jìn)一步的學(xué)習(xí)起著舉足輕重的作用。二、說(shuō)教學(xué)目標(biāo)教學(xué)目標(biāo)是教材的出發(fā)點(diǎn)和歸宿，也是檢查教學(xué)效果的標(biāo)準(zhǔn)和尺度。從教育學(xué)的角度來(lái)講教學(xué)目標(biāo)應(yīng)在基礎(chǔ)知識(shí)、能力培養(yǎng)、思想品質(zhì)三方面進(jìn)行明確。所以本節(jié)課的教學(xué)目標(biāo)是：

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑體部分在句中作表語(yǔ)。2. 句1、2、3中的that在從句中不作成分，只起連接作用。 Step2: Review the basic components of predicative clauses1.Definition

In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention，the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste. The people who drank this water were much more likely _10_________ (get) cholera than those who drank pure or boiled water. Through John Snow's efforts, the _11_________ (threaten) of cholera around the world saw a substantial increase.

Step 5： After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!
