PRACTICE TEST 5
THE DICTIONARY OF NATIONAL BIOGRAPHY
Just over one hundred years ago, the last volume of a tremendous work of reference
entitled The Dictionary of National Biographyrolled off the printing presses. (1)
(ADMIT), this 21-volume shelf-filler may not immediately sound like the most thrilling read
in the world. As entertainment, you might imagine it ranks some way below a (2)
(POLITICS) autobiography. But you would be very, very wrong.
The DNB, like the Oxford English Dictionary, is one of the great monuments to British
culture and also a hugely enjoyable work in its own right. It is, quite simply, an
(3) (ALPHABET) dictionary of potted biographies of all the notable men and
women who had lived in Britain since the year dot. It was produced between 1885 and 1900,
and it remains (4) (EMPHASIS) an achievement of the Victorian period, richly
redolent of 19th century confidence and (5) (CAPABLE), energy and optimism.
It is also a monument to the enormous variety of the British national character, and the
dictionary is immeasurably (6) (RICH) by this aspect. There are not only great
statesmen, generals, writers, but also hundreds of wonderfully (7) (COLOUR)
characters, who you can discover only by leafing idly through a volume of the DNB on a wet
afternoon down at your local library.
The way in which the DNB was produced was very British too: on a shoestring, out of sheer
dedication, and with no state (8 ) (INTERFERE) whatsoever. It was the private
endeavour of a group of (9) (ENTHUSE), scholars and freelance journalists, as
(10) (OPPOSE) to, for instance, the Austrian equivalent, produced under the
oppressive auspices of the imperial Academy of Vienna.
Key:
1. ADMITTEDLY
2. POLITICIAN'S
3. ALPHABETICAL
4. EMPHATICALLY
5. CAPABILITY

6. ENRICHED
7. COLOURFUL
8. INTERFERENCE
9. ENTHUSIASTS
10. OPPOSED
Cùng nhau thử sức với đề tiếp theo nào. Đề kì này khá dễ, chỉ cần cẩn thận thôi.
PRACTICE TEST 6
1. You survived the air crash. It's a (MIRACULOUS)
2. No details about the celebration have been given. (FAR)
3. The principal said some words to the pupils before the exam. (COURAGE)
4. Her car needs at the garage. (SERVICE)
5. There are some mysteries that remain (SOLVE)
6. may take place when you don't speak English correctly. (UNDERSTAND)
7. are doing their best to save the species from dying out. (ENVIRONMENT)
8. It is education that helps with the of knowledge for the young. (BROAD)
9. She has been with me for an hour about the future job. (REASONABLE)
10. She got an award for her intelligence. (ORDINARY)
Key:
1. MIRACLE. Từ loại cần điền ở đây là noun, và đây là noun của MIRACULOUS.
2. FURTHER. Như bạn rt giải thích, dạng comparative của far có thể là farther hoặc further.
Cả hai đều có thể dùng để chỉ về khoảng cách vật lí, nhưng further thường được dùng để chỉ
chiều dài thời gian hoặc chỉ mức độ. Vì vậy trong câu này ta dùng FURTHER là thích hợp
nhất.
3. ENCOURAGING.
4. SERVICING. Từ SERVICE ở đây mang nghĩa "bảo trì, bảo dưỡng (máy móc, động
cơ)" nên ta chỉ cần thêm -ING vào là được, không cần chuyển thành SERVE vì khi đó nó
mang nghĩa khác. Ở đây đòi hỏi phải có kiến thức văn phạm: need + V-ing = need to be +
Past Participle.
5. UNSOLVED là đáp án của mình, nhưng mình thấy đáp án INSOLVABLE cũng có thể
chấp nhận được trong trường hợp này. Từ loại cần điền ở đây là adjective.

6. MISUNDERSTANDING.
7. ENVIRONMENTALISTS.
8. BROADENING. Câu này có thể hiểu là "Chính sự giáo dục mới giúp mở rộng kiến thức
của thanh thiếu niên." Và từ loại cần điền ở đây là noun mang nghĩa "việc mở rộng". Vì thế
ta thêm hậu tố -EN để tạo verb rồi thêm -ING vào. Cấu trúc "the " ở đây không phải là
superlative đâu nhé.
9. REASONING. Nếu ở đây ta chia "reasoned" thì câu trở thành bị động, không thích hợp
với ngữ nghĩa. Tense được dùng ở đây là Present Perfect Progressive nên chữ "been" là của
tense, không phải của passive.
10. EXTRAORDINARY. Từ này mang nghĩ "đáng kinh ngạc, khó tin".
