Birds also sing to tell other birds to keep away. To a bird, his tree or even a branch of tree, is his home. He does not want strangers to come near him, so he sings to warn them.

If a bird cannot sing well, he usually has some other means of giving important information. Some birds dance, spread out their tails or make other sings. One bird has a most unusual way of finding a wife. It builds a small garden of shells and flowers.

Thanksgiving: An American Tradition

The American holiday of Thanksgiving is celebrated every year on the fourth Thursday in November. The holiday is during autumn -- the main season for harvesting crops. Thanksgiving is an autumn harvest festival like those found in many cultures around the world. On this day, most Americans gather with friends and family. Many take time to think about what they are thankful for, cook up a storm, and eat. A lot.

The star of most Thanksgiving dinners is a roasted turkey. Turkeys are large birds native to North America. The turkey is cooked in an oven for many hours, often with a mix of celery, bread, onions and spices inside the bird. This mix becomes stuffing -- another star of the Thanksgiving dinner table. After the bird is cooked, the stuffing is taken out and served as a side dish. One of many side dishes. Families often make other foods like mashed potatoes, sweet potatoes, cranberry sauce and vegetable casseroles.

Lễ Tạ ơn: Một truyền thống Mỹ
Kỳ nghỉ lễ Tạ ơn của người Mỹ được tổ chức hàng năm vào ngày thứ năm thứ tư của tháng 11. Kỳ nghỉ lễ là vào mùa thu - mùa chính để thu hoạch mùa màng. Lễ Tạ ơn là một lễ hội thu hoạch mùa thu như những ngày được tìm thấy trong nhiều nền văn hoá trên thế giới. Vào ngày này, hầu hết người Mỹ tụ tập với bạn bè và gia đình. Nhiều người mất thời gian để suy nghĩ về những gì họ cảm ơn, nấu ăn một cơn bão, và ăn. Rất nhiều.

Ngôi sao của hầu hết các bữa tiệc Lễ Tạ ơn là một con gà tây nướng. Gà tây là loài chim lớn có nguồn gốc ở Bắc Mỹ. Gà tây được nấu chín trong một lò trong nhiều giờ, thường với một hỗn hợp cần tây, bánh mì, hành tây và gia vị bên trong chim. Sự pha trộn này trở nên nhồi nhét - một ngôi sao khác của bàn ăn tối Tạ ơn. Sau khi chim được nấu chín, món nhồi được đưa ra và phục vụ như một món ăn phụ. Một trong nhiều món ăn phụ. Gia đình thường làm các loại thực phẩm khác như khoai tây nghiền, khoai lang, nước sốt cranberry và khoai tây.

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 35 to 44.

Bird migration is one of the most interesting yet least understood natural phenomena. Every fall birds from northern latitudes fly in groups to the warmer southern latitudes and then return north in the spring. Scientists agree on the main reasons for migration: to follow the food supply and to avoid harsh climate conditions. For example, insects disappear during the cold months, prompting insect-dependent birds to fly south to warm areas where insects breed. No similar consensus has emerged, however, about how birds are able to navigate. Despite many recent experiments, bird experts still do not know how birds arrive at the same destinations every year and then find their way back home in the spring.

Some have suggested that birds find their way by following landmarks, such as rivers and mountain ranges. Experiments have confirmed that some species do follow such topographic features. But that method cannot explain how some birds travel at night. Other studies show that some nocturnal birds navigate by the stars. But that explanation cannot explain daytime migration or travel when the skies are cloudy.

The most popular explanation currently is that birds are guided by Earth's magnetic poles. The mechanism by which that works has not yet been proved. One theory points to the fact that some birds' contain magnetite, a naturally occurring magnetic compound consisting of iron oxide. Magnetite has been found in many animals, including birds. With magnets embedded in their brains, birds would be able to sense the magnetic fields of the North and South Poles.

A recent experiment with homing pigeons provided some evidence that magnetite does play a crucial role in migration. Homing pigeons are known to have the ability to return to their homes after being taken hundreds of miles away. Researchers found that they could train homing pigeons to recognize changes in a magnetic field. When a surrounding magnetic field was normal, the birds would gather at one end of a cage. But when the field's polarity was altered, they hopped to the other end, suggesting that they were directing and responding to changes in the magnetic field.

Another theory has been offered to explain this sensitivity to magnetic poles, a theory that draws upon quantum mechanics, which is the study of how particles move inside an atom. It relies on the fact that electrons come in pairs that orbits the nucleus of an atom. The two electrons spin in opposite directions, creating two magnets that neutralize each other. But when molecules split and react with other molecules to form compounds, the electrons pairs may no longer spin in opposite directions. Instead, they may repel each other, as when two north ends of magnets are pressed together. The electrons struggle to change direction in order to achieve a stable state in which the two electrons again neutralize each other, giving off no magnetic field.

Question 35: The word "phenomena" in the passage is closest in meaning to

A. events          B. trends         C. discoveries         D. theories

Question 36: According to paragraph 1, insects influence bird migration in which of the following ways?

A. insects generate a magnetic field that birds can detect

B. Insects provide a food supply that exists only in warm climates

C. Birds follow the paths taken by flying insects

D. birds know when to migrate by a sudden increase in insect population

Question 37: The word "some" in the passage refers to

A. insects         B. recent experiments  C. bird experts       D. birds

Question 38: According to paragraph 3, birds can detect the magnetic fields of the North and South poles because

A. they sense the motion of electron pairs

B. they can locate the poles by following landmarks

C. they ingest metal particles that are attracted by the poles

D. they have magnetite in their brains

Question 39: The word "embedded" in the passage is closest in meaning to

A. implanted        B. attached         C. attracted        D. activated

Question 40: The author discusses "homing pigeons" in paragraph 4 in order to

A. provide an example of how humans can train birds

B. describe an experiment showing the importance of magnetite

C. show that homing pigeons return home by following landmarks

D. report homing pigeons' behavior inside a cage

Question 41: According to the passage, all of the following are theories about how birds navigate EXCEPT:

A. They follow landmarks like rivers and mountains

B. They are guided by their position relative to the stars

C. They feel vibrations in nerve endings in their brains

D. They respond to changes in light

Question 42: According to paragraph 4, the pigeons moved to the opposite end of a cage because

A. The magnetic field was normal

B. The magnetic field was stronger at one end

C. The magnetic field changed its polarity

D. The magnetic field was removed

Question 43: The word "altered" in the passage is closest in meaning to

A. reversed        B. cancelled        C. strengthened         D. detected

Question 44: Which of the following can be inferred about an electron pair in two north ends of magnets?

A. The two electrons spin in opposite directions

B. One electron will move to the south end

C. One electron will be captured by the nucleus

D. The two electrons spin in the same direction

Read the passage about clothes, then answer the questions below.

Clothes can tell a lot about a person. Some people like very colorful clothes because they want everyone to look at them and they want to be the center of things. Other people like to wear nice clothes, but their clothes are not colorful or fancy. They do not like people to look at them. Clothes today are very different from the clothes of the 1800s. One difference is the way they look. For example, in the 1800s all women wore dresses. The dresses all had long skirts.

But today women do not always wear dresses with long skirts .Sometimes they wear short skirts. Sometimes they wear pants. Another difference between1800s and today is the cloth. In the 1800s, clothes were made only from natural kinds of cloth. They were made from cotton, wool, silk, or linen. But today, there are many kinds of man–made cloth. A lot of clothes are now made from nylon, rayon, or polyester.

Why do some people like very colorful clothes?
