Exercise 10 Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions
Do you think education is better now than it was in your grandparents' time? Many older people in the UK believe the opposite “Schools were better in our day,” they complain “There isn't enough discipline these days Kids don't work as hard as we did, either The syllabus isn't as challenging, so clever students aren't being stretched enough They need to study things in greater depth Exams are much, much easier now as well.”
Were schools better years ago? Some British teenagers travelled back in time to a 1950s boarding school They got a big surprise! The first shock came when the teenagers met their new teachers Dressed in traditional black gowns, they look so frosty and uncaring! They were really authoritarian, too, so anyone caught breaking the rules - talking in classes, mucking about in the playground or playing truant – was in big trouble! Punishments included writing 'lines' or staying after class to detention The naughtiest kids were expelled
Things were just as bad after class At meal times the students had to endure a diet of plain, no-nonsense, healthy food Homework was obligatory and it took ages! Copying essays off the Internet wasn't an option, as personal computers didn't exist in the 1950s!
At the end of 'term' everyone sat 1950s-style exams The old exams were much longer than their twenty-first century equivalents and involved learning huge amounts of facts by heart History papers were all dates and battles Maths papers were trickier, too; calculators weren't around in the 1950s, so the students had to memorise multiplication tables and master long division Our candidates found this really difficult The exam results surprised a lot of people Students predicted to well in their real-life, twenty-first century exams often got low grades in the 1950s exams Does this prove modern exams are too easy? Do twenty-first century kids rely too much on modern technology, like calculators and computers?
(10)Bài tập Anh 11, Anh 12 – Lý 12 Website: www.thptthuanthanh1.bacninh.edu.vn schools These helped them learn job skills Boys studied subjects like metalwork, woodwork or
gardening In some classes, they even learned how to milk goats! The girls' timetables included secretarial skills They also learned to cook, clean and sew - probably not much fun for most girls
111 What criticism is sometimes made about modern education in the first paragraph? A Teachers aren't strict enough
B The syllabus is out of date C There's too much stress on exams
D The teaching methods are not good enough
112 The word "authoritarian” in the second paragraph is closest in meaning to
A inexperienced B impolite C unreasonable D strict 113 Which of the following statements is TRUE about the food the students ate at school?
A It wasn't cooked properly B It wasn't delicious C It wasn't nutritious D There wasn't much of it 114 The word "obligatory” in the third paragraph is closest in meaning to
A compulsory B difficult C long D complicated
115 According to the passage, how did exams in the 1950s differ from those in the twenty-first century? A They covered more subjects B It took students less time to them C There was more to remember D They were less difficult
116 What was surprising about the students' results after taking the 1950s-style exams? A All the students found the exams difficult
B Students didn't as well as expected
C Students who were predicted to fail did rather well D Students did better than twenty-first century exams 117 The word “these” in the last paragraph refers to
A school-kids B subjects C series D vocational schools 118 Which of the following statements is TRUE according to the passage?

The hard, rigid plates that form the outermost portion of the Earth are about 100 kilometers thick These plates include both the Earth's crust and the upper mantle The rocks of the crust are composed mostly of minerals with light elements, like aluminum and sodium, while the mantle contains some heavier elements, like iron and magnesium Together, the crust and upper mantle that form the surface plates are called the lithosphere This rigid layer floats on the denser material of the lower mantle the way a wooden raft floats on a pond The plates are supported by a weak, plastic layer of the lower mantle called the asthenosphere Also like a raft on a pond, the lithospheric plates are carried along by slow currents in this more fluid layer beneath them
With an understanding of plate tectonics, geologists have put together a new history for the Earth's surface About 200 million years ago, the plates at the Earth's surface formed a “supercontinent” called Pangaea When this supercontinent started to tear apart because of plate movement, Pangaea first broke into two large continental masses with a newly formed sea that grew between the land areas as the depression filled with water The southern one - which included the modern continents of South America, Africa, Australia, and Antarctica - is called Gondwanaland The northern one - with North America, Europe, and Asia - is called Laurasia North America tore away from Europe about 180 million years ago, forming the northern Atlantic Ocean Some of the lithospheric plates carry ocean floor and others carry land masses or a combination of the two types The movement of the lithospheric plates is responsible for earthquakes, volcanoes, and the Earth's largest mountain ranges Current understanding of the interaction between different plates explains why these occur where they For example, the edge of the Pacific Ocean has been called the “Ring of Fire” because so many volcanic eruptions and earthquakes happen there Before the 1960's, geologists could not explain why active volcanoes and strong earthquakes were concentrated in that region The theory of plate tectonics gave them an answer
Question 36 With which of the following topics is the passage mainly concerned? A The contributions of the theory of plate tectonics to geological knowledge B The mineral composition of the Earth's crust
C The location of the Earth's major plates
D The methods used by scientists to measure plate movement
Question 37 According to the passage, the lithospheric plates are given support by the A upper mantle B ocean floor C crust D asthenosphere
Question 38 The author compares the relationship between the lithosphere and the asthenosphere to which of the following?
A Lava flowing from a volcano B A boat floating on the water
C A fish swimming in a pond D The erosion of rocks by running water Question 39 The word “one” in the passage refers to
A movements B masses C sea D depression
Question 40 According to the passage, the northern Atlantic Ocean was formed when A Pangaea was created B plate movement ceased
C Gondwanaland collided with Pangaea D parts of Laurasia separated from each other Question 41 Which of the following can be inferred about the theory of plate tectonics?
(22)Bài tập Anh 11, Anh 12 – Lý 12 Website: www.thptthuanthanh1.bacninh.edu.vn B It was first proposed in the 1960's C It fails to explain why earthquakes occur D It refutes the theory of the existence of a supercontinent

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
The changing profile of a city in the United States is apparent in the shifting definitions used by the United States Bureau of the Census In 1870 the census officially distinguished the nation's “urban” from its “rural” population for the first time “Urban population” was defined as persons living in towns of 8,000 inhabitants or more But after 1900 it meant persons living in incorporated places having 2,500 or more inhabitants Then, in 1950 the Census Bureau radically changed its definition of “urban” to take account of the new vagueness of city boundaries In addition to persons living in incorporated units of 2,500 or more, the census now included those who lived in unincorporated units of that size, and also all persons living in the densely settled urban fringe, including both incorporated and unincorporated areas located around cities of 50,000 inhabitants or more Each such unit, conceived as an integrated economic and social unit with a large population nucleus, was named a Standard Metropolitan Statistical Area (SMSA)
Each SMSA would contain at least (a) one central city with 50,000 inhabitants or more or (b) two cities having shared boundaries and constituting, for general economic and social purposes, a single community with a combined population of at least 50,000, the smaller of which must have a population of at least 15,000 Such an area included the county in which the central city is located, and adjacent counties that are found to be metropolitan in character and economically and socially integrated with the county of the central city By 1970, about two-thirds of the population of the United States was living in these urbanized areas, and of that figure more than half were living outside the central cities
While the Census Bureau and the United States government used the term SMSA (by 1969 there were 233 of them), social scientists were also using new terms to describe the elusive, vaguely defined areas reaching out from what used to be simple “towns” and “cities” A host of terms came into use: “metropolitan regions,” “polynucleated population groups”, “conurbations,” “metropolitan clusters,” “megalopolises,” and so on
Question 46 What does the passage mainly discuss?
A How cities in the United States began and developed
B Solutions to overcrowding in cities C The changing definition of an urban area D How the United States Census Bureau conducts a census
Question 47 According to the passage, the population of the United States was first classified as rural or urban in
A 1870 B 1900 C.1950 D.1970 Question 48 Which of the following is NOT true of an SMSA?
A It has a population of at least 50,000 B It can include a city's outlying regions C It can include unincorporated regions D It consists of at least two cities Question 49 The Census Bureau first used the term “SMSA” in
A 1900 B 1950 C 1969 D 1970
Question 50 Prior to 1900, how many inhabitants would a town have to have before being defined as urban?

Basic to any understanding of Canada in the 20 years after the Second World War is the country's impressive population growth For every three Canadians in 1945, there were over five in 1966 In September 1966 Canada's population passed the 20 million mark Most of this surging growth came from natural increase The depression of the 1930's and the war had held back marriages, and the catching-up process began after 1945 The baby boom continued through the decade of the1950's, producing a population increase of nearly fifteen percent in the five years from 1951 to 1956 This rate of increase had been exceeded only once before in Canada's history, in the decade before 1911 When the prairies were being settled Undoubtedly, the good economic conditions of the 1950's supported a growth in the population, but the expansion also derived from a trend toward earlier marriages and an increase in the average size of families In 1957 the Canadian birth rate stood at 28 per thousand, one of the highest in the world
After the peak year of 1957, the birth rate in Canada began to decline It continued falling until in 1966 it stood at the lowest level in 25 years Partly this decline reflected the low level of births during the depression and the war, but it was also caused by changes in Canadian society Young people were staying at school longer; more women were working; young married couples were buying automobiles or houses before starting families; rising living standards were cutting down the size of families It appeared that Canada was once more falling in step with the trend toward smaller families that had occurred all through the Western world since the time of the Industrial Revolution

Let children learn to judge their own work A child learning to talk does not learn by being corrected all the time If corrected too much, he will stop talking He notices a thousand times a day the difference between the language he uses and the language those around him use Bit by bit, he makes the necessary changes to make his language like other people’s In the same way, children learn all the other things they learn to without being taught – to talk, run, climb, whistle, ride a bicycle – compare their own performances with those of more skilled people, and slowly make the needed changes But in school we never give a child a chance to find out his mistakes for himself, let alone correct them We it all for him We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to Soon he becomes dependent on the teacher Let him it himself Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not
If it is a matter of right answers, as it may be in mathematics or science, give him the answer book Let him correct his own papers Why should we teachers waste time on such routine work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer Let’s end all this nonsense of grades, exams, and marks Let us throw them all out, and let the children learn what all educated persons must someday learn, how to measure their own understanding, how to know what they know or not know
Let them get on with this job in the way that seems most sensible to them, with our help as school teachers if they ask for it The idea that there is a body of knowledge to be learnt at school and used for the rest of one’s life is nonsense in a world as complicated and rapidly changing as ours Anxious parents and teachers say, “But suppose they fail to learn something essential, something they will need to get on in the world?” Don’t worry! If it is essential, they will go out into the world and learn it

One of the most interesting authors of the twentieth century, J.R.R Tolkien, achieved fame through his highly inventive trilogy The Lord of the Rings Born in 1892, Tolkien received his education from Oxford and then served in World War I After the war, he became a professor of Anglo -Saxon and English language and literature at Oxford University
Although published in 1965, the three books that comprise the Lord of the Rings were written in intervals from 1936 to 1949 This was mainly due to Tolkien's responsibilities as a professor and the outbreak of World War II By the late 1960s, this fascinating trilogy had become a sociological phenomenon as young people intently studied the mythology and legends created by Tolkien
The trilogy is remarkable not only for its highly developed account of historical fiction but also its success as a modern heroic epic The main plot describes the struggle between good and evil kingdom as they try to acquire a magic ring that has the power to rule the world The novels, which are set in a time called Middle Earth, describe a detailed fantasy world Established before humans populated the Earth, Middle Earth was inhabited by good and evil creatures such as hobbits, elves, monsters, wizards, and some humans The characters and the setting of Middle Earth were modeled after mythological stories from Greece and Northern Europe
Although readers have scrutinized the texts for inner meaning and have tried to connect the trilogy with Tolkien's real life experiences in England during World War II, he denied the connection He claims that the story began in his years as an undergraduate student and grew out of his desire to create mythology and legends about elves and their language
