Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Early humans saw a variety of natural colours around them, from the browns and greens of the soil and plants to the deep blues and red of the sky. They painted their bodies with colours from nature to signal aggression toward an enemy, or to make themselves attractive to a mate.

A girl and a rainbow of crushed ice flavors at Chowpatty Beach, India. Over the centuries, the sources of colours such as blue, purple, and red were high valued and they were often  worth as much as gold.  In the 19th century, a young chemistry student manufactured the first synthetic dye, and suddenly the world became a much more colorful place. In the 20th century, scientists discovered the psychological effects of colours, and people found ways to use this discovery to influence our feelings and behaviors.

RED

Red, colour of blood, symbolises fire, love and anger. In Eastern cultures, people believe it brings luck, wealth and success. In humans, the color red can send different messages. Some people redden, for example, when they are angry or embarrassed.  Researchers have discovered that in sports the team that is wearing red is more likely to win. Why? Because red seems to be the color that signals dominance, giving those dressed in red an advantage in sporting  events. In many animal species (including humans), contact with this bold color causes the heart rate to increase. However, one of red’s lighter shades, pink, can have the opposite effect on people. Man in prisons are less agressive when the walls are a specific shade of pink.

YELLOW

Yellow, the colour that comes to mind when we think of sunshine, is found throughout nature and the man-made world as a colour that commands attention; indeed, it is one of the easiest colours to see. This highly visible shade is found on everything from school buses to traffic signs and pens that we use to highlight important information in a text. The colour is also used to caution people; football players, for example, are shown a yellow card as a reminder to behave. It can be used as a stimulant as well: in a number of studies, yellow has been found to help children focus on their work and do better at school.

BLUE

Blue, the colour of the sky and sea, is associated in many cultures with water, religious objects, and protection against evil. Its darker shades represent calm, stability and power. Dark blue, for example, is the colour of the business suit or police uniform; it tells others, ‘I am in control,’ or ‘I am trustworthy.’ Blue is also associated with sadness. It’s common in English, for example, when you are feeling sad or depressed, to talk about ‘feeling blue,’ while in Iran, blue is the colour of mourning, worn when a person dies. Like pink, blue has a calming effect on people. Rooms painted blue help people to relax or sleep. Sleeping pills are often coloured blue to suggest exactly this idea. This colour also seems to reduce feelings of hunger. Blue food is rarely seen in nature, and when it is, such food is usually no longer healthy to consume. It’s just one more example of the power that colour can hold over us.

According to the pasage, the colour red______.

A. is believed to embarrass people

B.   gives an advantage to team members who wear it.

C.   symbolises bad luck

D.   makes people less aggressive.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34.

Genetic modification of foods is not a new practice. It has been practiced for thousands of years under the name of "selective breeding". Animals and plants were chosen because they had traits that humans found useful. Some animals were larger and stronger than others, or they yielded more food, or they had some other trait that humans valued. Therefore, they were bred because of those traits. Individuals with those traits were brought together and allowed to breed in the hope that their offspring would have the same traits in greater measure.

Much the same thing was done with plants. To produce bigger or sweeter fruit, or grow more grain per unit of land, strains of plants were combined and recombined to produce hybrids, or crossbreeds that had the desired traits in the right combinations. All the while, however, biologists wondered: is there a more direct and versatile way to change the traits of plants and animals? Could we rewrite, so to speak, the heredity of organisms to make them serve our needs better?

In the 20th century, genetic modification made such changes possible at last. Now, it was possible to alter the genetic code without using the slow and uncertain process of selective breeding. It even became possible to blend plants and animals genetically: to insert animal genes into plants, for example, in order to give the plants a certain trait they ordinarily would lack, such as resistance to freezing. The result was a tremendous potential to change the very nature of biology.

The word "them" in paragraph 2 refers to ______.

A. organisms 

B. traits 

C. animals 

D. plants

All the while, however, biologists wondered: is there a more direct and versatile way to change the traits of plants and animals? Could we rewrite, so to speak, the heredity of organisms to make them serve our needs better?

In the 20th century, genetic modification made such changes possible at last. Now, it was possible to alter the genetic code without using the slow and uncertain process of selective breeding. It even became possible to blend plants and animals genetically: to insert animal genes into plants, for example, in order to give the plants a certain trait they ordinarily would lack, such as resistance to freezing. The result was a tremendous potential to change the very nature of biology

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34.

Genetic modification of foods is not a new practice. It has been practiced for thousands of years under the name of "selective breeding". Animals and plants were chosen because they had traits that humans found useful. Some animals were larger and stronger than others, or they yielded more food, or they had some other trait that humans valued. Therefore, they were bred because of those traits. Individuals with those traits were brought together and allowed to breed in the hope that their offspring would have the same traits in greater measure.

Much the same thing was done with plants. To produce bigger or sweeter fruit, or grow more grain per unit of land, strains of plants were combined and recombined to produce hybrids, or crossbreeds that had the desired traits in the right combinations. All the while, however, biologists wondered: is there a more direct and versatile way to change the traits of plants and animals? Could we rewrite, so to speak, the heredity of organisms to make them serve our needs better?

In the 20th century, genetic modification made such changes possible at last. Now, it was possible to alter the genetic code without using the slow and uncertain process of selective breeding. It even became possible to blend plants and animals genetically: to insert animal genes into plants, for example, in order to give the plants a certain trait they ordinarily would lack, such as resistance to freezing. The result was a tremendous potential to change the very nature of biology

Which of the following IS NOT achieved by genetic modification? 

A. Giving plants necessary traits taken from animals’ genes 

B. Producing hybrids or crossbreeds from many animals and plants 

C. Encouraging people to give up selective breeding completely 

D. Making big changes to the very nature of biology

Cái nào sau đây không đạt được bởi biến đổi gen?

  A. Cung cấp cho thực vật những đặc tính cần thiết từ gen động vật

  B. Sản xuất giống lai khác loài hoặc lai khác giống từ nhiều động vật và thực vật

  C. Khuyến khích mọi người hoàn toàn bỏ gây giống có chọn lọc

  D. Tạo ra những thay đổi lớn với bản chất của sinh học

Dịch bài đọc:

Biến đổi gen của thực phẩm không phải là một thực hành mới mẻ. Nó đã được thực hiện hàng ngàn năm qua dưới cái tên “gây giống chọn lọc”. Động vật và thực vật được chọn lựa bởi vì chúng có những đặc tính mà con người thấy hữu dụng. Một vài con vật thì to hơn và khỏe hơn những con khác, hoặc chúng sản xuất ra nhiều thực phẩm, hoặc là chúng có đặc tính khác mà con người thấy giá trị. Do đó, chúng được nhân giống vì các đặc tính như vậy. Các cá thể với đặc tính đó được tập hợp lại và được cho phép sinh sản với hi vong rằng con cái của chúng sẽ có cùng đặc tính giống nhau trong số lượng lớn hơn.

Nhiều điều tương tự cũng đã thực hiện trên thực vật. Để tạo ra quả to hơn và ngọt hơn, hoặc trồng được nhiều ngũ cốc hơn trên một đơn vị đất đai, các chủng loại thực vật được kết hợp và tái kết hợp lại để tạo ra các giống lai khác loài hoặc giống lai khác giống, có những đặc tính mong muốn trong các kết hợp đúng. Suốt thời gian đó, tuy nhiên, các nhà khoa học đã tự hỏi: liệu có các nào trực tiếp và linh hoạt hơn để thay đổi các đặc tính của động vật và thực vật không? Chúng ta có thể viết lại, có thể nói như vậy, sự di truyền của các sinh vật để khiến chúng phục vụ nhu cầu của chúng ta tốt hơn?

Trong thế kỷ hai mươi, cuối cùng thì biến đổi gen cũng đã tạo ra được những thay đổi. Ngày nay, có khả năng để thay đổi mã di truyền mà không cần sử dụng quá trình gây giống có chọn lọc vừa chậm và không chắc chắn nữa. Thậm chí đã trở nên có khả năng pha trộn về gen của thực vật và động vật: để chèn các gen động vật vào thực vật, ví dụ, để cung cấp cho thực vật một đặc tính nhất định mà chúng nói chung đang thiếu, như là khả năng chống đóng băng. Kết quả này là một tiềm năng to lớn để thay đổi bản chất của sinh học
