Read the text and choose the answer (A, B, C or D) which you think fits best according to the text. (10pts) Life originated in the early seas less than a billion years after the Earth was formed. Yet another three billion years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on mega fossils-relatively large specimens of essentially whole plants and animal. Vascular plants, related to modern seed plants and ferns, left the first comprehensive mega fossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by animals that preyed on the plant-eater. Moreover,the mega fossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago.Recently, however, paleontologists have been taking a closer look at the sediments below this Silurian-Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rocks in an acid bath. The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans-plant microfossils and microscopic pieces of small animals. In many instances the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism.These newly discovered fossils have not only revealed the existence of previously unknown organisms, but have also pushed back these dates for the invasion of land by multi-cellular organisms. Our views about the nature of the early plant and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms.

Student life and technologyScience and technology
By Debra Mallin, a business student at Greyfort University

Last Saturday, as my grandfather drove me and my sister home from a dinner to celebrate his birthday, he got frustrated at not being able to remember the name of the singer of a song he’d just heard on the radio. Without a second thought, I grabbed my smartphone, searched for the song and found the name, Bob Dylan. For me and my friends, this is a completely natural course of action, but it totally astonished my grandfather, who didn’t understand how I had checked the information so quickly. My sister and I laughed and explained, but afterwards, it made me think about how much I depend on technology.

The list of the ways I use technology is endless: writing, planning, socialising, communicating and shopping, to name a few. When I reflected on its impact on my education, I saw that, for my fellow students and I, technology has been significant in many ways. Returning to the story of my grandfather and the smartphone, he had asked me more about how I used it and about university life. He said he thought we had an easy life compared to previous generations. My sister caught my eye and we exchanged a smile. But whereas she was thinking our grandfather was just being a typical 65-year old, I could see his point.

Not only are we lucky enough to have the same educational benefits as those of previous generations, we have so many more as well. We still have walk-in libraries available to us, and I can see why some students choose to find and use resources in these distraction-free locations. However, the only option for studying used to be sitting in these libraries with as many books from your reading list as you could find, yet now a single search for your chosen study topic online can immediately provide access to a huge range of resources. At universities, interaction between students and university staff is another area that has changed considerably with developments in technology. We can have face-to-face time with our tutors when we need it, and also communicate using our electronic gadgets from the comfort of our homes, or on the bus. The most popular means of doing this is via instant messaging or social media – email is often considered too slow, and it has become unacceptable for messages to be unanswered for any length of time. While this puts an extra strain on the university’s academic support team, who usually have to answer the queries as they come in, we students are greatly benefitted.

It’s important that we remember to appreciate how much the advances in technology have given us. Electronic devices such as tablets, smartphones, and laptops are now standard equipment in most classrooms and lecture halls, and why shouldn’t they be? The replacement of textbooks with tablets allows students the luxury of having up-to-date, interactive and even personalised learning materials, with the added benefit of them not costing the earth.

When we compare the student life of the past and that of the present day, it is tempting to focus on the obvious differences when it comes to technology. In actual fact, students are doing what they’ve always done:
embracing the resources available and adapting them in ways which allow them to work more efficiently and to
live more enjoyably. The pace of change in technology continuously gathers speed, so we have to value each
innovation as it happens.

1. What does the writer illustrate by describing the incident in the car? *

1 điểm

A the older generation’s frustration at people’s dependence on technology

B how unaware young people are of some effects of technology

C the difference in attitudes to technology between two generations

D how technology helps different generations communicate

2. What did the writer think of her grandfather’s comment, mentioned in the second paragraph? *

1 điểm

A It showed how out-of-date he was.

B It had an element of truth in it.

C It was an annoying thing to say.

D It made her feel sorry for him.

3. What does the writer say about getting study resources from libraries? *

1 điểm

A She considers libraries more preferable places for study than home.

B She cannot understand why anyone chooses to go to a library now.

C She appreciates the fact that people can still study in libraries if they want to.

D She thinks libraries are limited by the quantity of resources they can store.

4. What disadvantage of new technology does the writer mention in the third paragraph? *

1 điểm

A Those who can afford the best gadgets gain an unfair advantage.

B Sometimes slow internet connections make communication difficult.

C A heavier workload is created for teaching staff at the university.

D Students cannot escape from dealing with university issues.

5. What is the purpose of the question ‘Why shouldn’t they be?’ in the fourth paragraph? *

1 điểm

A to express an opinion

B to introduce some problems

C to make a criticism

D to indicate uncertainty

6. What is the writer’s conclusion about students today in the final paragraph? *

1 điểm

A They have such different lives to previous generations that it’s unwise to compare them.

B They deal better with change than previous generations did.

C They take advantage of new resources more quickly than previous generations did.

D They are behaving in a similar way to previous generations of students.

Life originated in the early seas less than a billion years after Earth was formed. Yet another three billion years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.

What forms of life were able to make such a drastic change in lifestyle?

Vascular plants, related to modern seed plants and ferns, left the first comprehensive mega fossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by animals that preyed on the plant-eaters.

Life originated in the early seas less than a billion years after Earth was formed. Yet another three billion years were to pass before the first plants and animals appeared on the continents.

Thông tin: Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.

Dịch nghĩa: Quá trình chuyển đổi của cuộc sống từ biển vào đất có lẽ cũng là một thách thức tiến hóa như là nguồn gốc của sự sống.

Phương án A. The evolution of terrestrial life was as complicated as the origin of life itself = Sự tiến hóa của sự sống trên cạn cũng phức tạp như nguồn gốc của sự sống, lợi nhuận; là phương án chính xác nhất.

B. The discovery of microfossils supports the traditional view of how terrestrial life evolved = Việc phát hiện ra vi cổ ủng hộ quan điểm truyền thống của cuộc sống về việc cuộc sống trên mặt đất phát triển như thế nào.

Life originated in the early seas less than a billion years after Earth was formed. Yet another three billion years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.

What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on mega fossils — relatively large specimens of essentially whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive mega fossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by animals that preyed on the plant-eaters. Moreover, the mega fossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago. Recently, however, paleontologists have been taking a closer look at the sediments below this Silurian-Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rocks in an acid bath. The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans — plant microfossils and microscopic pieces of small animals. In many instances the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism.

These newly discovered fossils have not only revealed the existence of previously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms. Our views about the nature of the early plant and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms.

Which of the following resulted from the discovery of microscopic fossils?

A. The time estimate for the first appearance of terrestrial life-forms was revised

B. Old techniques for analyzing fossils were found to have new uses

C. The origins of primitive sea life were explained

D. Assumptions about the locations of ancient seas were changed
