Danh từ – Khái niệm và các loại danh từ
1. Danh từ – Khái niệm
Danh từ trong tiếng Anh tương tự với tiếng Việt, được sử dụng để chỉ sự vật, sự việc và con người. Danh từ có thể xuất hiện ở các vị trí khác nhau trong câu. Có 5 loại danh từ cơ bản, bao gồm danh từ chung, danh từ riêng, danh từ trừu tượng, danh từ tập hợp và danh từ ghép.
2. Các loại danh từ
-
Danh từ chung: Chỉ tên chung cho một loại đối tượng, vật dụng như “school” (trường học), “hospital” (bệnh viện), “table” (cái bàn), “house” (ngôi nhà),…
-
Danh từ riêng: Chỉ tên riêng của người, địa điểm, vật, chữ cái đầu phải viết hoa như “David Beckham”, “London”, “Buddhism”,…
-
Danh từ trừu tượng: Chỉ những thứ trừu tượng không thể nhìn thấy được nhưng có thể cảm nhận được như “love” (tình yêu), “sadness” (buồn), “opinion” (ý kiến), “knowledge” (kiến thức),…
-
Danh từ tập hợp: Chỉ tên một nhóm, một tập hợp các cá thể khác nhau như “family” (gia đình), “class” (lớp học), “group” (nhóm), “crowd” (đám đông),…
-
Danh từ ghép: Là các danh từ được ghép lại với nhau để tạo thành một danh từ khác như “bedroom” (phòng ngủ), “mineral water” (nước khoáng), “mother-in-law” (mẹ vợ),…
Cách hình thành danh từ
1. Tạo danh từ từ các hậu tố
Ngoài các danh từ có sẵn, ta có thể hình thành danh từ từ các loại từ khác như động từ và tính từ.
-
Động từ – Danh từ: “arrive” – “arrival”, “perform” – “performance”, “educate” – “education”,…
-
Tính từ – Danh từ: “sad” – “sadness”, “national” – “nationality”, “minimal” – “minimalism”,…
2. Tạo danh từ từ danh từ
Ta có thể tạo danh từ mới bằng cách kết hợp hai danh từ lại với nhau.
- A/An/The + Noun1 + Noun2
- Noun1: Đóng vai trò như tính từ bổ nghĩa cho Noun2
- Noun2: Danh từ chính
- Ví dụ: The “city center” (Trung tâm thành phố), A “taxi driver” (Người lái xe taxi)
3. Tạo danh từ từ V-ing
Những danh từ có V-ing đứng trước thường để biểu thị mục đích sử dụng của danh từ đó.
Ví dụ: A “frying pan” (= a pan used for frying), A “washing machine” (= a machine used for washing clothes)
4. Tạo danh từ từ số đếm
Ta có thể tạo danh từ bằng cách kết hợp số đếm với danh từ.
Ví dụ: A “ten-hour flight” (Chuyến bay kéo dài 10 tiếng), A “seven-storey building” (Tòa nhà cao 7 tầng)
Lưu ý: Danh từ đứng sau số đếm là dạng số ít: A “ten-year old boy” (Cậu bé 10 tuổi)

Some people believe that developments in the field of artificial intelligence will have a positive impact on our lives in the near future. Others, by contrast, are worried that we are not prepared for a world in which computers are more intelligent than humans. Discuss both of these views and give your own opinion.
People seem to be either excited or worried about the future impact of artificial (1-intelligence)___. Personally, I can understand the two (2-opposing)__ points of view; I am both fascinated by developments in artificial intelligence and apprehensive about its possible negative effects.
On the one hand, the increasing intelligence of technology should bring some obvious benefits. Machines are clearly able to do many jobs better than humans can, especially in areas that require high levels of (3-accuracy)__ or calculations using large amounts of data. For example, robots are being developed that can carry out surgical procedures with greater (4-precision)__ than a human doctor, and we already have cars that use sensors and cameras to drive themselves. Such technologies can improve safety by reducing the (5-likelihood)__ of human errors. It is easy to imagine how these developments, and many others, will steadily improve our quality of life.
On the other hand, I share the concerns of people who believe that artificial intelligence may harm us if we are not careful. In the short term, it is likely that we will see a rise in (6-unemployment)__ as workers in various industries are replaced by machines or software programs. For example, self-driving vehicles are expected to cause (7-redundancies)__ in driving jobs, such as lorry drivers, taxi drivers, and bus drivers. In the medium term, if intelligent technologies gradually take jobs away from humans, we may find that people become deskilled and lose their sense of purpose in life. A longer-term fear is that computers become so intelligent that they begin to make (8-decisions)__ without human oversight and without regard for our well-being.
In conclusion, while intelligent machines will no doubt improve our lives in many ways, the potential risks of such technologies should not be ignored.

(1)A bar chart shows the number of British people who emigrated to five destinations over (2)the period 2004 to 2007. It is evident from the chart that throughout the period, the most popular place to move to was Australia.
Emigration to Australia stood at just over 40,000 people in 2004, which was approximately 6,000 higher than for Spain, and twice as high as the other three countries. Apart from a jump to around 52,000 in 2006, it remained around this level throughout the period.
(3)The next most popular country for Britons to move to was (4)Spain, though its popularity declined over the time frame to finish at below 30,000 in 2007. Despite this, the figure was still higher than for the remaining three countries. Approximately 20,000 people emigrated to New Zealand each year, while the USA fluctuated between 20-25,000 people over the period.
Although (5)the number of visitors to France spiked to nearly 35,000 in 2005, it was the country that was the least popular to emigrate to at the end of the period, at just under 20,000 people.

There are several reasons that are causing the environmental harms and this has become (1)an urgent issue to discuss and bring (2)a solution about. The number of ever-increasing cars is one of (3)the reasons that lead to affect the environment negatively and there are some assumptions that increasing the fuel price would solve this problem. But the reality would be different, and an increased fuel price will cause lots of other problems while it would contribute very little to reduce the environmental pollutions and hazards. So this can’t be the best solution in any way.
First of all, the maximum number of cars are owned by the rich people and a fuel price would not restrain them from using the cars. The price of (4)fuel, in fact, increased significantly over the past 12 years and that has done nothing to reduce the car usage. On the contrary, the number of cars running on the roads has increased more than expected. Besides, (5)the fuel price determines the market prices of other daily necessary products, and increasing the price would only bring misery to the low and medium-earning class population. Electronic waste, industries, household electrical devices, deforestation, chemical waste, unthoughtful activities of people are causing more damage to Mother Earth than the gas emission by the cars. We should focus on those aspects as well before increasing the price of fuel just based on (6)an assumption.
The main idea of increasing the fuel price is to reduce (7)the number of cars running in the street and to restrain car owners from using the cars less. But that would prove to be (8)a ridiculous solution, especially when car owners are mostly high-earning class and they would not bother about the fuel price.
The best solution to address this utmost concerning issue is to introduce (9)an environmentally friendly energy source like solar energy systems, to improve the public transportation system & train system so that people mostly use these systems instead of always using their own cars, increasing the awareness of the people so that they do not directly contribute to harming the environment, and making strict rules so that deforestation, chemical waste, and other harmful ways of (10)environmental pollution get reduced.

The line graph shows the percent of tourists to England who visited certain Brighton attracts between 1980 and 2010. We can see that in 1980 and in 2010 the favorite attractions were the pavilion and the festival. In 1980 the least popular attraction was the pier but in 2010 this changed, and the art gallery was the least popular.
During the 1980s and 1990s, there was a sharpened increase in visitors to the pavilion from 28% to 48%, and then the percentage gradually went down to 31% in 2010. The trend for the art gallery was similar to the pavilion. Visitors increased rapidly from 22% to 37% from 1980 to 1985, then gradually decreased to less than 10% over the next twenty-five years. The number of tourists who visited the Brighton Festival fluctuated slightly but, in general, remained steady at about 25%. Visitors to the pier also fluctuated from 1980 to 2000, then rose significantly from 12% to 22% between 2000 and 2010.
