Graph can be a very useful tool for conveying information, especially numbers, percentages, and other data. A graph gives the reader a picture to interpret. That can be a lot more efficient than pages and pages explaining the data.
Graphs can seem frightening, but reading a graph is a lot like reading a story. The graph has a title, a main idea, and supporting details. You can use your active reading skills to analyze and understand graphs just like any other text.
Most graphs have a few basic parts: a caption or introduction paragraph, a title, a legend or key, and labeled axes. An active reader looks at each part of the graph before trying to interpret the data. Captions will usually tell you where the data came from (for example, a scientific study of 400 African elephants from 1980 to 2005). Captions usually summarize the author's main point as well. The title is very important. It tells you the main idea of the graph by stating what kind of information is being shown. A legend, also called a key, is a guide to the symbols and colors used in the graph. Many graphs, including bar graphs and line graphs, have two axes that form a corner. Usually these axes are the left side and the bottom of the graph. Each axis will always have a label. The label tells you what each axis measures.
Bar Graphs
A bar graph has two axes and uses bars to show amounts. In Graph 1, we see that the x-axis shows grades that students earned, and the y-axis shows how many students earned each grade .You can see that 6 students earned an A because the bar for A stretches up to 6 on the vertical measurement. There is a lot of information we can get from a simple graph like this(See Graph 1).
Line Graphs
A line graph looks similar to a bar graph, but instead of bars, it plots points and connects them with a line. It has the same parts as a bar graph – two labeled axes –and can be read the same way. To read a line graph, it’s important to focus on the points of intersection rather than the line segments between the points. This type of graph is most commonly used to show how something changes over time. Here is a graph that charts how far a bird flies during the first five days of its spring migration (See Graph 2).
The unit of measurement for the x-axis is days. The unit of measurement for the y-axis is kilometers. Thus we can see that, on the first day, the pipit flew 20 kilometers. The line segment goes up between Day 1 and Day 2,which means that the bird flew farther on Day 2. If the line segment angled down, as between Day 4 and Day 5, it would mean that the bird flew fewer kilometers than the day before. This line graph is a quick, visual way to tell the reader about the bird’s migration.
Pie Graphs
A typical pie graph looks like a circular pie. The circle is divided into sections, and each section represents a fraction of the data. The graph is commonly used to show percentages; the whole pie represents l00 percent, so each piece is a fraction of the whole.
A pie graph might include a legend,or it might use icons or labels within each slice. This pie graph shows one month’s expenses (See Graph 3 ).

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 ______.
A. Out of order B. Less colorful
C. hard to predict D. full of meanings

Artificial intelligence (AI) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like breast cancer in ways that were never before possible.
Rishi Rawat teaches AI at the University of Southern California’s (USC) Clinical Science Center in Los Angeles. He is part of a team of scientists who are researching how AI and machine learning can more easily recognize cancerous growths in the breast. Rawat provides information about cancer cells to a computer. He says this data helps the machine learn. “...You can put the data into them and they will learn the patterns and the pattern recognition that’s important to making decisions.”
David Agus is another USC researcher. He believes that “machines are not going to take the place of doctors.” He adds, “Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can’t recognize these patterns by itself.”
Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer. Currently, researchers take a thin piece of tissue, put it on a small piece of glass and add color to better see the cells. This process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns, or structures, and learn how the cells are organized. The hope is that machines will soon be able to make a quick diagnosis(诊断)of cancer that is free of human mistakes.
“All of a sudden, we have the computing power to really do it in real time...We couldn’t have done this, we didn’t have the computing power to do this several years ago, but now it’s all changed.” Agus adds that the process could be done “for almost no cost in the developing world.” He says that having a large amount of information about patients is important for a machine to effectively do its job in medicine.
A doctor faces a series of critical decisions every day. The best a doctor can do is to make those decisions as informed as possible. Some of them are still hard to make. A doctor can ask people of whom he values their opinions and that’s it. Imagine discussing these with an AI system that is even more rational(理性的)than anyone else.
The University of Southern California researchers are now only studying breast cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.
1.According to Rawat and David Agus, AI can be used to ___________.
A. take the place of doctors B. treat all forms of cancer
C. remove doctors’ mistakes D. help doctors diagnose cancer
2.From the passage, we learn that doctors may benefit from AI because it can ___________.
A. use data to recognize patterns of cancer
B. decide on the form of cancer treatment
C. reduce the risk of cancer returning
D. monitor the medical procedure
3.What does the underlined word “critical” in Paragraph 6 mean?
A. reliable B. important
C. evident D. doubtful
4.What’s the best title for the passage?
A. How Do AI Systems Work? B. Can AI Cure Cancer?
C. Can AI Make Doctors Better? D. How Can Doctors Use AI?

Beijing residents could be rewarded with up to 500,000 yuan if they can provide useful information on spies or related activities, according to a government policy that took effect on Monday.
Under the policy, informants will be offered rewards ranging, from 10,000 yuan to 500,000 yuan, depending on how useful the information is, according to the policy issued by the National Security Bureau(安全局) of Beijing. Informants can pass information to authorities by calling a hotline, sending letters or visiting the bureau.
Informants' privacy and information about spy-related messages will not be disclosed, while information providers can ask authorities for protection if they or their relatives are in danger due to the act of informing, according to the policy.
However, informants will face punishments if they slander (诽谤) others on purpose or invent and spread false information, the policy states clearly.
The bureau said that China is witnessing rapid increases in international exchanges and the number of people entering or exiting the country each year. "Meanwhile, overseas espionage agencies(间谍机构)and other unfriendly forces have also strengthened their disruptive(破坏的) activities in China, including political, economical and military information." it said.
Some Chinese individuals have also betrayed the nation to benefit their private interests, which offers overseas espionage agencies opportunities, the bureau said, adding that Beijing is the primary location for such activities. Therefore, it's necessary to take new measures in anti-espionage investigation, and to encourage the participation of the general public.
One of the most recent cases made public occurred in the eastern province of Jiangsu in January. Two residents in Lianyungang city, surnamed Zhang and Wan, called the national security authorities after they found a device with instructions in foreign languages while fishing in the Yellow Sea. The device was later found to be spying equipment made and used by overseas agencies to collect data, according to an official release.
China has strengthened Iegislation(立法) on State security in recent years. Facing a more complex State security situation, in 2014, the Standing Committee of the National People's Congress adopted the Counterespionage Law.
1.From the passage, we can learn that ________.
A. few citizens show an interest in the policy
B. informants are always offered rewards for their reports
C. informants will definitely make great fortunes
D. informants might come across a certain risk
2.Which of the following is NOT true?
A. Information can be offered via different means.
B. It is more effective to get ordinary people involved.
C. No citizens have associated with overseas espionage agencies.
D. Whoever makes up false information will be punished.
3.Based on the passage, we can conclude that ________.
A. spies take advantage of our opening-up policy
B. the example mentioned is just a rare exception
C. with the Counterespionage Law, the security situation has improved a lot
D. overseas espionage agencies are only interested in Beijing
4.Where is the passage likely to be taken from?
A. A textbook. B. A newspaper.
C. A legal document. D. A story-book.

A CV is a sales document; it conveys the information of what you are looking for and why. Why you are qualified for such work, covering your previous work experience, education, qualification and interests, so effort should be made to make CV as clear as possible in order to sell you most effectively for the post which you are applying for.
Profile
The profile should be a short sentence stating clearly:
•What work you are looking for
• What you have to offer (Why you are qualified)
I believe in starting the CV with a profile. This explains to the employer what you are looking for and summarizes all of the attributes ( 特质) that can be found in detail on the rest of your CV.
The employer knows what they are looking for. If your profile states this in summary, then you are making their job a lot easier and they are more likely to put you in the “yes" pile, as they quickly check a large volume of CVs.
Work Experience
Work experience should come directly after the profile in reverse chronological (反向时间 顺序) order. The first thing an employer will look at is the last job you have had and if you had the relevant experience or achieved something relevant to the job you are applying for in previous roles.
Education
Education should be also in reverse chronological order.
Other Qualifications
If you have attended any training courses or have industrial qualifications they should be entered here. Remember this is a sales document ― list everything you have done here — sell yourself!
Interests
Qualify you hobbies and interests. Do not mention a thing like "I like to go running" without qualifying it as to what has been achieved. For example, it would be better to say “I am part of the Harriers running club.” or “I recently completed the Great North Run."
1.If your profile states your attributes in summary, you'll____.
A.make your job a lot easier
B.be sure to persuade the employer
C.be more likely to get the job
D.fail to pass the interview
2.To write a good CV, you have to _______.
A.tell everything you've experienced in detail
B.place the Profile after the Work Experience
C.use only short sentences to express yourself
D.present the relevant facts to the employers
3.Which is the most concerned by the possible employer?
A.Your interests.
B.Your last job.
C.Your training courses.
D.Family background.

A while ago, people used to believe that only humans can use tools — but Jane Goodall showed that humans aren’t the only ones to do so. We’ve since found several species that build and use their own tools. Then, many thought that it’s our cultural and family ties that separate us from the animals. Actually, that’s not true either. Several other species, including whales, have shown important cultural behaviors.
Researchers have found that related whales returned to the same locations year after year, and decade after decade, passing the information from one generation to the next. Researchers analyzed the structure of the beluga whale society, finding that migratory culture is inherited(继承). Furthermore, this cultural inheritance maintains the family ties of beluga whales. This cultural legacy(遗传)is so powerful that some travel as far as 6,000 kilometers each year.
“What interested us most was whether particular whales returned to where they were born or grew up and if this was an inherited behavior,” said Greg O’ Corry-Crowe, Ph.D., lead author and a research professor at FAU’s Harbor Branch. “The only way that we could definitively answer these questions was to find and track close relatives from one year to the next and one decade to the next.”
Researchers also found that beluga whales exhibit an impressively broad range of vocal repertoires and acoustic systems(复杂的声音体系)which suggests that they form complex interpersonal relationships. They like to hang out in the thousands near shore during the summer when the ice melts. Eventually, researchers hope that this will not only enable us to better understand these surprisingly complex species but also develop better ways to protect them in the face of a changing environment — the polar regions, where the beluga whales live, are extremely exposed to climate change.
“Findings from our study are expanding our understanding of how complicated non- primate(非灵长类)societies can be and how important culture is for the survival of these species,” said O’ Corry-Crowe. “Our findings also will influence our thinking in terms of how populations and species are going to adapt to dramatic environmental changes. There are few places where this is more urgent than in the rapidly changing polar regions.”
1.According to the passage, whales usually .
A. produce their tools B. use their own tools
C. live near the coast D. have their cultural ties
2.It can be inferred that migratory culture has .
A. a short and insignificant effect on beluga whales
B. inherited from the structure of beluga whale society
C. a long and far-reaching effect on beluga whales
D. attracted beluga whales to several fixed locations
3.What’s the purpose of the research?
A. To find beluga whales’ behaviors.
B. To find beluga whales’ acoustic systems.
C. To find beluga whales’ interpersonal relationships.
D. To better understand and protect beluga whales.
4.Why does O’ Corry-Crowe consider it urgent to understand beluga whales’ adaption to their surroundings?
A. Because of the very sophisticated non-primate societies.
B. Because of the rapid environmental changes in polar regions.
C. Because of the misunderstanding of beluga whales’ migrations.
D. Because of the too far distance for beluga whales to migrate.
