process solar water heating system

Đề bài:  The diagram shows a method for warming  water by using  indirect solar water heating system

Bài làm (155 words)

 The diagram highlights  a process for heating water by using a Solar system 

Overall, the Solar water heating system consists of 3 main parts: Solar collector panel, heat transfer unit and storage tank. 

First, the Heat transfer unit is provided with cold water. Here, it is pumped into the solar collector panel through a pine line. An antifreeze solution is added to the pine line to prevent water from being frozen. After that,  the cold water travels to a  solar collector panel. Here the solar collector panel warms the cold water thanks to its heat collected from absorbing sunlight. When water is warmed by the solar collector panel, it will go directly to the heat transfer unit which is also equipped with a heating coin that helps warm the water again. At this point, the warm water is conveyed to a storage tank for later usage. 

In conclusion, The solar water heating system uses sunlight to warm water. 

Essay: learning foreign languages

Essay:

In some school systems, Children start learning at least one foreign language in primary school. In other school systems, foreign language begins in secondary school. In your opinion, should children learn foreign languages in schools, and if so, at what age they begin? 

Outline

Agree

The development of brain for children in the early ages, especially 4-9 is very fast -> learning foreign languages more effectively
 EX: a lot of children can use multiple languages 
As we grow older, it is hard for us to acquire a foreign language because our brain becomes less sharp.
Disagree 

Children should focus on their mother tongue. 
When they are grown up and master their mother tongue, they can learn other languages. 

Nowadays, Learning  foreign languages plays a vital role in the success of a person with the increasing globalization besides academic subjects. The ages  at which people should learn foreign languages attract people’s attention. Some people argue that primary school is a better place for children to learn  a second language instead of having to wait for secondary school. I am in favor of the idea. 

On the one hand, Learning foreign languages in primary schools brings children better results. First and foremost, The development of brain for children in early ages, especially 4-9 age group, is very fast. This helps Learning foreign languages among children become more effective. We can see a lot of children use multiple languages in daily life. Secondly, As we grow older, it is hard for us to acquire foreign language skills because our brain becomes less sharp. That is to say, many adults have to struggle with foreign languages while it is easy for children, especially at young ages to comprehend another language. 

On the other hand, many people argue that it is better for children to learn foreign languages when they are secondary school students. Therefore, Children in primary schools should study more important academic subjects like math, science, mother tongue.. instead of foreign languages which can be learned later when children reach secondary schools.  

In conclusion, Children are required to study foreign languages as soon as they are able to, especially when they enter primary schools so that they can achieve utmost  results  in mastering other languages rather than having to wait for  a few more years.

Outline 

Advantage Disadvantage 
The government have more money from tax to invest … Less people use private cars -> reducing traffic jam, the number of car accidentsCar industry face/encounter  difficulties -> Car companies may go bankrupt -> leading to the high rate of unemployment This can cause  a financial burden on drivers 

Viet bai 

Mo bai: 

Nowadays, traffic issues are increasingly serious. To tackle (solve, address) these, the government should impose a  large amount of levy (money from taxation)  on private vehicle owners. I think this practice (solution/measure) has both the positives and the negatives.

 Doan 1 

Topic: 

On the one hand, taxing private car owners highly has some benefits. 

Firstly, the government will increase more tax money (levy)  on private vehicles. Therefore, They can spend this kind of money on enhancing (improving/upgrading/intensifying/boosting) public transportation such as trains, buses, infrastructures…

Secondly, When public means of transportation gradually become more developed and modernized, more people prefer to commute (travel) by this kind of transportation, leading to (resulting in) the decrease (slump) in the number of people (commuters/travelers)using private cars. As a result, This will partly contribute to solving (handling/tackling/addressing)traffic problems such as traffic jams (traffic congestions), car accidents… which are mainly caused (inflicted)by private cars. 

Doan 2 

Topic: 

On the other hand, Economy and the owners also suffer from (endure) financial issues if they are taxed (levied) heavily (massively=extremely, greatly)

First and foremost, taxing Cars highly discourages (deter/prevent/stop) people from buying cars. This can cause a negative impact (influence/effect/consequence)  on the car industry in particular as well as (and) the economy in general. 

Hence,  a great deal of  (many)  car manufacturers may go bankrupt if less people travel by private vehicles, possibly leading to (resulting in/causing)the high rate of unemployment.

What’s more (in addition), drivers who use private cars have to spend an extra sum of money on the additional tax. This can cause (inflict) a financial burden on them, especially on people of the middle-class. 

In conclusion, imposing (forcing/urging/enforcing) heavy tax on private car owners brings advantages and disadvantages. The government needs to take this into consideration.
