The peregrine falcon, a predatory bird indigenous to North America, was once in danger of extinction. In the 1960s, scientists discovered byproducts of the pesticide DDT in the birds' eggs, which caused them to be too soft to survive. The use of the pesticide had been 5 banned in the United States, but the falcons were eating migratory birds from other places where DDT was still used. In order to increase the survival rate, scientists were raising the birds in laboratories and then releasing them into mountainous areas. This practice achieved only moderate success, however, because many of the birds raised 10 in captivity could not survive in the wild.
There is now, however, a new alternative to releases in the wild. A falcon that has been given the name Scarlett chose to make her home on a ledge of the 33rd floor of a Baltimore, Maryland, office 15 building rather than in the wild, and, to the surprise of the scientists, she has managed to live quite well in the city. Following this example, programs have been initiated that release birds like Scarlett into cities rather than into their natural wild habitat. These urban releases are becoming a common way to strengthen the species. Urban homes 20 have several benefits for the birds that wild spots do not. First, there is an abundance of pigeons and small birds as food sources. The peregrine in the city is also protected from its main predator, the great horned owl. Urban release programs have been very successful in reestablishing the peregrine falcons along the East Coast. Though 25 they are still an endangered species, their numbers increased from about 60 nesting pairs in 1975 to about 700 pairs in 1992. In another decade the species may flourish again, this time without human help.

Jan Dibbets may someday have his work revered as much as his Dutch predecessors Vermeer, Van Gogh, and Rembrandt. At a time when the trends in art are toward abstraction and minimalism, Dibbets' work integrates these two disparate trends into one remarkable whole. 5 In one series of composite works, he arranged sections of architectural photographs into rounded patterns. Then, with pen and ink and watercolors, he connected the segments together into 360-degree circular forms blending the abstract with the real and the imagined.

Read the passage and answer the following questions: Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose and 5 amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person's diet. This translates to about 75-100 grams of carbohydrates per day.
A diet that is deficient in carbohydrates can have an adverse effect 10 on a person's health. When the body lacks a sufficient amount of carbohydrates it must then use its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a build-up of ketones 15 in the body that causes fatigue, lethargy, and bad breath. 1. What is the main idea of this passage?
(A) Carbohydrates are needed for good health.
(B) Carbohydrates prevent a build-up of proteins.
(C) Carbohydrates can lead to ketosis.
(D) Carbohydrates are an expendable part of a good diet.

(A) neglect
(B) serve
(C) dissolve
(D) profess
3. The word "range" as used in line 3 is closest in meaning to which of the following?
(A) probe
(B) proceed
(C) hail
(D) extend
4. In line 5, the word "estimate" could best be replaced by
(A) disbelieve
(B) declare
(C) calculate
(D) wonder
5. According to the passage, what do most nutritionists suggest?
(A) Sufficient carbohydrates will prevent gluconeogenesis.
(B) Carbohydrates are simple sugars called glucose.
(C) Carbohydrates should make up about a quarter of a person's daily diet.

Since the world has become industrialized, there has been an increase in the number of animal species that have either become extinct or have neared extinction. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300, and by 5 the year 2025 their population is estimated to be down to zero. What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not interested in material gain but in personal gratification. This is an example of the callousness that is part 10 of what is causing the problem of extinction. Animals like the Bengal tiger, as well as other endangered species, are a valuable part of the world's ecosystem. International laws protecting these animals must be enacted to ensure their survival, and the survival of our planet.
15 Countries around the world have begun to deal with the problem in various ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission to help defray the costs of maintaining the parks, 20 and they often must also depend on world organizations for support. With the money they get, they can invest in equipment and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of products made from endangered species. This seems fairly effective, but it 25 will not, by itself, prevent animals from being hunted and killed.

A balanced diet contains proteins, which are composed of complex amino acids. There are 20 types of amino acids, comprising about 16 percent of the body weight in a lean individual. A body needs all 20 to be healthy. Amino acids can be divided into two groups: essential 5 and nonessential. There are 9 essential amino acids. These are the proteins that the body cannot produce by itself, so a healthy individual must ingest them. The 11 nonessential amino acids, on the other hand, are produced by the body, so it is not necessary to ingest them. Proteins are described as being either high-quality or low-quality, 10 depending on how many of the 9 essential amino acids the food contains. High-quality proteins, typically found in animal meats, are proteins that have ample amounts of the essential amino acids. Low-quality proteins are mainly plant proteins and usually lack one or more of the essential amino acids. Since people who follow a strict vegetarian 15 diet are ingesting only low-quality proteins, they must make sure that their diets contain a variety of proteins, in order to ensure that what is lacking in one food is available in another. This process of selecting a variety of the essential proteins is called protein complementation. Since an insufficient amount of protein in the 20 diet can be crippling, and prolonged absence of proteins can cause death, it is imperative that a vegetarian diet contains an ample amount of the essential proteins.

A balanced diet contains proteins, which are composed of complex amino acids. There are 20 types of amino acids, comprising about 16 percent of the body weight in a lean individual. A body needs all 20 to be healthy. Amino acids can be divided into two groups: essential 5 and nonessential. There are 9 essential amino acids. These are the proteins that the body cannot produce by itself, so a healthy individual must ingest them. The 11 nonessential amino acids, on the other hand, are produced by the body, so it is not necessary to ingest them. Proteins are described as being either high-quality or low-quality, 10 depending on how many of the 9 essential amino acids the food contains. High-quality proteins, typically found in animal meats, are proteins that have ample amounts of the essential amino acids. Low-quality proteins are mainly plant proteins and usually lack one or more of the essential amino acids. Since people who follow a strict vegetarian 15 diet are ingesting only low-quality proteins, they must make sure that their diets contain a variety of proteins, in order to ensure that what is lacking in one food is available in another. This process of selecting a variety of the essential proteins is called protein complementation. Since an insufficient amount of protein in the 20 diet can be crippling, and prolonged absence of proteins can cause death, it is imperative that a vegetarian diet contains an ample amount of the essential proteins.

Đề bài: Write the comparative forms of the adjective/adverbs in the bracket ( và giải thích tại sao điền như vậy)
1. The countryside is (crowded) ...more crowded.. and (tranquil) ..tranquil... than cities.
* Ta thấy trg câu có than -> so sánh hơn
crowded và tranquil lại 2 Adj_ dài
-> more Adj .... and Adj than
2. I guess that ploughing machine can plough very much (fast) ...faster. than a buffalo.
than -> so sánh hơn với Adj _ ngắn
3. Good healthcare service can be (easy) ..easier... found in rural areas than in cities.
Than -> so sánh hơn
easy là một trường hợp tính từ dài đặc biệt.
Trg câu so sánh hơn easy -> easier
4. Farmers often have to get up (early) ...earlier.. than city dwellers.
* Cái này cx là trương hợp ngoại lệ luôn. Với hầu hết các Adj có 2 âm tiết tận cùng là "y" -> bỏ "y" thêm "ier"
