Human beings are in for a double treat in Jan...

Human beings are in for a double treat in January with the appearance of two supermoons. The first one rises on the night of New Year’s Day. The second comes on the last night of the month, ending up with a lunar eclipse (月食). That is the end of a trilogy (三部曲) of big moon treats that began in Dec. 3 with a full cold moon. The Jan. 1 supermoon will be the biggest of the year. The moon will appear to be oversized for a few nights after that, though it will no longer be a full moon.

A supermoon is a full moon that appears at the closest point in the moon’s orbit to earth, about 14 percent larger and 30 percent brighter than full moons that appear at the farthest point in the orbit. Supermoons hang around all night, are easy to see and are not damaging to the eyes, no matter how long you moon-gaze.

For those who may miss the night of Jan. 1, an even more charming supermoon will rise on the night of Jan. 31. That will be the second full moon of the month, which is usually called a “blue moon” because a double full-moon month occurs essentially once in a blue moon—about every 2.5 years. A blue moon is even rarer when it’s a supermoon. But that won’t be the only rarity that night. The super blue moon will also occur during a total lunar eclipse. If skies are clear, the total eclipse will be visible from eastern Asia across the Pacific Ocean to western North America.

Lunar eclipses make moons appear blood red because of the way the blocked sunlight bends, when the earth moves between the sun and the moon, blocking the sun’s light from reflecting off the moon. So prepare yourself for the super blue blood moon on the night of the lunar eclipse. To get the full effect of the lunar eclipse, watch at moonset.

1.What does the underlined word “That” in Paragraph 1 refer to?

A. The lunar eclipse.　　 B. The New Year’ s Day.

C. The biggest supermoon.　　 D. The supermoon of Jan. 31.

2.What can we learn about the supermoon on Jan. 31 from the text?

A. It will begin with a lunar eclipse.　　 B. It will be a super blue moon.

C. It will be observed all over the world,　　 D. It will be the biggest moon of the year.

3.What does the author advise observers to do about the lunar eclipse on Jan. 31?

A. Film the whole lunar eclipse with mobile phones.

B. Decide the spot first when they watch it.

C. Watch it when the moon sets.

D. Prepare sunglasses because the moon is too bright.

4.Which of the following can be the best title for the text?

A. Supermoons with A Lunar Eclipse　　 B. The Definition of A Supermoon

高二英语单项填空中等难度题查看答案及解析

DNA is one of the most important discoveries in science. DNA is the plan for the human being, as a blueprint is the plan for a building. DNA makes a person look the way he does. A person’s DNA comes from a mixing of his parents’ DNA. That’s why a child looks like his parents. But, besides controlling things such as height and hair color, DNA can also give people diseases. Scientists are now studying DNA to cure diseases.

In the seventies, scientists developed a process called recombinant or RDNA. Although it sounds difficult to understand, RDNA simply means taking DNA from one animal or plant and putting it into another. By doing so, scientists can create new beings. In doing so, scientists can better understand DNA, especially what parts of DNA do what. After they understand DNA, scientists can begin to cure diseases. Often, the new being created will itself be the cure.    Besides curing diseases, RDNA research can also do other things. For example, scientists in Japan have already created “super-trees”. Trees help humans, because they take CO₂, which poisons humans, from the air and turns it into oxygen, which lets humans breathe. “Super-trees” do this too, but do it much faster. As things such as cars and factories have already put much CO₂ in the area, “super-trees” are badly needed.

Unfortunately, there is a serious danger in RDNA research. Scientists want to create animals to cure old diseases, but these new animals may also create new diseases. It will be a serious problem if the animals escape from the science laboratory and into nature. As these animals are not natural, they may let loose many new powerful diseases.

As a result, RDNA research will create many solutions, but it will also create many problems.

1. From the passage, we can know that a boy looks like his parents because______.

A. he is son of his parents.

B. his parents’ DNA decides his appearance.

C. he has received DNA from his father or his mother.

2.What does the underlined expression “let loose” probably mean?

A. let … go free                B. get rid of

C. absorb                     D. survive

3. What is the best title for the passage?

Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.

Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.

Since 1960 a new kind of tool has appeared. This is the silicon chip -- a little chip of silicon crystal. It is smaller than a finger nail, but it can store more than a million "bits" of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways.　 In the future we will not need to work with tools in the old way. Machines will do everything for us. They will even talk and play games with us. People will have plenty of spare time. But what will they do with it?

Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years

from now?

1.From paragraph，we can know　　　　　　　　　　　　 .

A. why early human beings cut skin from dead animals

B. how early human beings discovered the tools

C. what early human beings used the tools for

D. what food early human beings stored

2.The stone chip is thought to be the most important tool because it ______.

A. was very important to the development of mankind

B. led to the invention of machines in the early time

C. developed cooking abilities of mankind

D. was one of the first tools of mankind

3.The silicon chip is mentioned in the passage to________.

A. show the changes of tools

B. introduce a new kind of tool

C. give an example of using tools

D. compare the effects of two kinds of tools

4.At the end of the passage the author seems to suggest that life in future is ______.
