Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 36 to 42.

Life originated in the early seas less than a billion years after the Earth was formed. Yet another three billions 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 megafossils - relatively large specimens of essential whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive megafossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of 10 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 the animals that preyed on the plant-eaters. Moreover, the megafossils 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 sediments below this Silurian- Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rock 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 discovered fossils have not only revealed the existence ofpreviously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms. Our view about the nature of the early plants and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms.

Đáp án C

Trong đoạn văn, từ "extracted" xuất hiện trong câu sau: “It turns out that some fossils can be extracted from these sediments by putting the rock in an acid bath.”

Ta có: “extracted: lấy ra, loại bỏ”

Xét về nghĩa, ta thấy các đáp án:

A. located: nằm, vị trí

B. preserved: bảo quản

C. removed: loại bỏ

D. studied: nghiên cứu

Dịch nghĩa:

“Sự sống bắt nguồn từ biển vào thời kỳ đầu, chưa đầy một tỷ năm sau khi Trái Đất hình thành. Ba tỷ năm nữa đã trôi qua trước khi các thực vật và động vật đầu tiên xuất hiện trên các lục địa. Quá trình chuyển đổi của sự sống từ biển sang đất liền có thể là một thử thách tiến hóa lớn như sự khởi nguồn của sự sống.

Những hình thức sống nào đã có thể thực hiện sự thay đổi lối sống mạnh mẽ như vậy? Quan điểm truyền thống về các sinh vật đất liền đầu tiên dựa trên các hóa thạch lớn – những mẫu vật lớn của các thực vật và động vật nguyên thủy còn khá hoàn chỉnh. Các thực vật có mạch, liên quan đến các loài cây hạt giống và dương xỉ hiện đại, đã để lại dấu ấn hóa thạch lớn đầu tiên. Chính vì vậy, người ta đã giả định rằng chuỗi sự kiện "xâm chiếm đất liền" phản ánh sự tiến hóa của các hệ sinh thái đất liền hiện đại. Theo quan điểm này, các thực vật có mạch nguyên thủy đã chiếm lĩnh các khu vực bờ biển của các vùng nước lục địa, tiếp theo là động vật ăn thực vật, và cuối cùng là các động vật ăn thịt những động vật ăn cỏ. Hơn nữa, các hóa thạch lớn cho thấy sự sống trên đất liền đã xuất hiện và phát triển mạnh mẽ vào khoảng ranh giới giữa thời kỳ Silurian và Devonian, cách đây hơn 400 triệu năm.

Tuy nhiên, gần đây, các nhà cổ sinh vật học đã tiến hành nghiên cứu kỹ hơn các trầm tích dưới ranh giới địa chất Silurian-Devonian này. Hóa ra một số hóa thạch có thể được lấy ra từ các trầm tích này bằng cách cho đá vào bể axit. Kỹ thuật này đã phát hiện ra bằng chứng mới từ các trầm tích được lắng đọng gần bờ biển của các đại dương cổ đại – các vi hóa thạch thực vật và các mảnh nhỏ của động vật. Trong nhiều trường hợp, các mẫu vật có đường kính nhỏ hơn một phần mười milimét. Mặc dù chúng đã bị chôn vùi trong đá hàng trăm triệu năm, nhưng nhiều hóa thạch vẫn giữ được phần hữu cơ của sinh vật.

Những hóa thạch mới được phát hiện không chỉ tiết lộ sự tồn tại của những sinh vật chưa từng biết đến trước đây, mà còn đẩy lùi thời gian xâm chiếm đất liền của các sinh vật đa bào. Quan điểm của chúng ta về bản chất của các cộng đồng thực vật và động vật đầu tiên giờ đây đang được sửa đổi. Và cùng với những sự sửa đổi đó là những suy đoán mới về các dạng sự sống đầu tiên trên đất liền.”

CÂU HỎI HOT CÙNG CHỦ ĐỀ

Câu 1:

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

The need for a surgical operation, especially an emergency operation, almost always comes as a severe shock to the patient and his family. Despite modern advances, most people still have an irrational fear of hospitals, and anaesthetics. Patients do not often believe they really need surgery - cutting into a part of the body as opposed to treatment with drugs.

In the early years of the 20th century there was little specialization in surgery. A good surgeon was capable of performing almost every operation that had been advised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves repaired. Clogged blood vessels can be cleaned out, and broken ones mended or replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live comfortable and satisfactory life. However, not every surgeon wants to, or is qualified to carry out every type of modern operation.

The scope of surgery has increased remarkably in the past decades. Its safety has increased too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions, for example to certain types of birth defects in new born babies, and, at the other end of the scale, to life saving operations for the octogenarian. The hospital stay after surgery has been shortened to as little as a week for most major operations. Most patients are out of bed on the day after an operation and may be back at work in two or three weeks.

Many developments in modern surgery are almost incredible. They include replacement of damaged blood vessels with simulated ones made of plastic: the replacement of heart valves with plastic substitutes; the transplanting of tissues such as lens of the eye; the invention of the artificial kidney to clean the blood of poisons at regular intervals and the development of heart and lung machines to keep patients alive during very long operations. All these things open a hopeful vista for the future of surgery.

One of the most revolutionary areas of modem surgery is that of organ transplants. Until a few decades ago, no person, except an identical twin, was able to accept into his body the tissues of another person without reacting against them and eventually killing them. Recently, however, it has been discovered that with the use of X-rays and special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have also been reasonably successful.

"Spare parts" surgery, the simple routine replacement of all worn-out organs by new ones, is

still a dream of the future but surgery is ready for such miracles. In the meantime, you can be happy if your doctors say to you, "Yes, I think it is possible to operate on you for this condition."

Question 45: A patient can still live a comfortable life even after the removal of _________.
