The attribution of human characteristics to animals or inanimate objects appears in the mythologies of many cultures is a literary device called anthropomorphism

Xem đáp án

Đáp án B

Appears -> appearing. Sử dụng mệnh đề quan hệ dạng rút gọn

Nhận xét: đây là một câu phân loại khó vì nhiều từ mới, học sinh mới đầu nhìn sẽ bị loạn bởi cả từ vựng và ngữ pháp. Phân tích về mặt ngữ pháp ta thấy đấy là một câu đơn nhưng lại có đến 3 động từ: appear, is, call. Ta đi phân tịch cấu trúc SVO của câu: Trong câu động từ is không bị gạch chân tức là is là được chia đúng, và chủ ngữ trong của động từ là “The attribution (A) of human characteristics to animals or inanimate objects” , ta lại thấy động từ appear cũng lại được chia theo chủ ngữ “The attribution (A) of human characteristics to animals or inanimate objects” nên là sai vì trong câu chỉ có thể có 1 động từ chính là “is”. Còn động từ called không sai vì đó là dạng rút gọn của mệnh đề quan hệ “which is called” bổ sung ý nghĩa cho danh từ đứng trước nó literacy device.

The attribution of human characteristics to animals or inanimate objects

                              S

(appears in the mythologies of many cultures)

MDDQH dạng rút gọn: appears -> appearing/ which appears
is ( Verb) a literary device called anthropomorphism (O)


Câu 7:

Mark the letter A, B, C, or D on your answer sheet to indicate the underlined part that needs correction in each of the following questions.
That inventors in the stock market enjoys increases and suffer declines is simply a fact of the financial market, and a small inventor is not too excited about the former or crestfallen about the latter.

Xem đáp án

Đáp án A

Enjoys -> enjoy do chủ ngữ là inventors ở dạng số nhiều

Nhận xét: câu này là câu cũng làm cho học sinh khá confused vì lại thấy từ that đi với danh từ số nhiều inventors, tuy nhiên cần phải nhìn và phân tích câu lại một lượt

That inventors in the stock market enjoys increases and suffer declines

                    S (noun clause bắt đầu bằng that: việc….)

is (V) simply a fact of the financial market (O), and a small inventor (S) is not (V) too excited about the former or crestfallen about the latter. (O) Vậy nên động từ enjoy phải chia theo chủ ngữ inventors, còn động từ is chia theo noun clause (động từ theo sau noun clause luôn phải là ở dạng số ít). Ngoài ra ta thấy trong mệnh đề danh từ còn có động từ suffer không bị gạch chân và đã chia ở dạng số nhiều theo đúng inventors, nếu học sinh nào nhanh mắt có thể để ý ngay đến động từ này và phát hiện lỗi sai ở enjoys vì enjoys lại chia ở dạng số ít

Câu 38:

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 38 to 42.

(1) Interest is the sum charged for borrowing money for a fixed period of time. Principal is the term used for the money that is borrowed, and the rate of interest is the percent per year of the principal charged for its use. Most of the profits for a bank are derived from the interest that they charge for the use of their own or their depositor’s money.

(2) All problems in interest may be solved by using one general equation that may be stated as follows:

Interest = Principal X Rate X Time

(3) Any one of the four quantities – that is, interest, principal, rate, or time – may be found when the other three are known. The time is expressed in years. The rate is expressed as a decimal fraction. Thus, 6 percent interest means six cents charged for the use of $1 of principal borrowed for one year. Although the time may be less than, equal to, or greater than one year, most applications for loans are for periods of less than one year. For purpose of computing interest for short periods, the commercial year or 360 days is commonly used, but when large sums of money are involved, exact interest is computed on the basis of 365 days.

Câu 43:

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

(1) The protozoans, minute, aquatic creatures each of which consists of a single cell of protoplasm, constitute a classification of the most primitive forms of animal life. They are fantastically diverse, but three major groups may be identified on the basis of their motility. The Mastigophora have one or more long tails, which they use to project themselves forward. The Ciliata, which use the same basic means for locomotion as the Mastigophora, have a larger number of short tails. The Sarcodina, which include amoebae, float or row themselves about on their crusted bodies.

(2) In addition to their form of movement, several other features discriminate among the three groups of protozoans. For example, at least two nuclei per cell have been identified in the Ciliata, usually a large nucleus that regulates growth but decomposes during reproduction, and a smaller one that contains the genetic code necessary to generate the large nucleus.

(3) Protozoans are considered animals because, unlike pigmented plants to which some protozoans are otherwise almost identical, they do not live on simple organic compounds. Their cell demonstrates all of the major characteristics of the cells of higher animals.

(4) Many species of protozoans collect into colonies, physically connected to each other and responding uniformly to outside stimulae. Current research into this phenomenon, along with investigations carried out with advanced microscopes may necessitate a redefinition of what constitutes protozoans, even calling into question the basic premise that they have only one cell. Nevertheless, with the current data available, almost 40,000 species of protozoans have been identified. No doubt, as the technology improves our methods of observation, better models of classification will be proposed.

once in a while: thỉnh thoảng

all of a sudden: một cách bất ngờ
in the long run: sau cùng, rốt cuộc là


Câu 49:

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

(1) The protozoans, minute, aquatic creatures each of which consists of a single cell of protoplasm, constitute a classification of the most primitive forms of animal life. They are fantastically diverse, but three major groups may be identified on the basis of their motility. The Mastigophora have one or more long tails, which they use to project themselves forward. The Ciliata, which use the same basic means for locomotion as the Mastigophora, have a larger number of short tails. The Sarcodina, which include amoebae, float or row themselves about on their crusted bodies.

(2) In addition to their form of movement, several other features discriminate among the three groups of protozoans. For example, at least two nuclei per cell have been identified in the Ciliata, usually a large nucleus that regulates growth but decomposes during reproduction, and a smaller one that contains the genetic code necessary to generate the large nucleus.

(3) Protozoans are considered animals because, unlike pigmented plants to which some protozoans are otherwise almost identical, they do not live on simple organic compounds. Their cell demonstrates all of the major characteristics of the cells of higher animals.

(4) Many species of protozoans collect into colonies, physically connected to each other and responding uniformly to outside stimulae. Current research into this phenomenon, along with investigations carried out with advanced microscopes may necessitate a redefinition of what constitutes protozoans, even calling into question the basic premise that they have only one cell. Nevertheless, with the current data available, almost 40,000 species of protozoans have been identified. No doubt, as the technology improves our methods of observation, better models of classification will be proposed.
