Irish teens make a breakthrough in crop yields（产量）
16-year-old Ciara Judge, Emer Hickey, and Sophie Healy-Thow won the Google Science Fair2014, with their project “Natural Bacteria Fighting World Hunger”.
While learning about the food shortage in Africa, the three teens got thinking about how they could help. What they found may change the future of worldwide food production.. They experimented and were able to reduce germination（发芽）time by 50%and increase plants’ yield by up to 74%.
This could create the possibility of increased crop yields and reducing crop loss due to bad weather.
Cancer is cured?
In May 2014, the Mayo Clinic published a study in which they treated a 50-year-old female patient’s blood cancer with the measlesvaccine（麻疹疫苗）.After receiving the vaccine, Stacy Erholtz’s body is completely free of cancer.
Stephen Russell, who led the research, said, “It’s a landmark. We’ve known for a long time that we can introduce a virus into the blood and destroy cancer in mice. Nobody’s shown that you can do that in people before.” The measles vaccine will not work for all types of cancer, but is an unbelievable step forward.
Water found on Saturn’s moon Enceladus
In April, scientists announced that NASA’s Cassini spacecraft discovered a body of water on Enceladus, a moon of Saturn（土星）. Enceladus is an icy moon about 300 miles in diameter （直径）.and its mysterious body of water appears to be 5 miles deep, around the size of Lake Superior.

Scientific discoveries have changed man's life a great deal during the past century. First of all, they have greatly improved material well-being in several areas of life. In the field of medicine, cures for life threatening diseases have enabled people to live longer. In communication, the telephone and e-mail have made it possible for us to communicate with anyone in the world without leaving our homes or offices. Advances in transportation allow businessmen to fly across the ocean in the morning and return home the same evening. Space technology has put men on the moon. More efficient ways of using available resources, such as coal and solar power, have been explored.
Scientific discoveries have also changed man's moral atmosphere. Ethical (伦理的) issues are raised by these discoveries. Should we keep a terminally ill person alive through drugs and machines or should we allow him to die in dignity? With advances in transportation had come the problem of pollution for nearly every major city in the world. If cities become uninhabitable, then such technical advances may come with too great a price to pay. Many people also question the wisdom of sending men to the moon when there are urgent problems that have not been solved on earth. During future years, increasing attention must be given to the moral as well as the practical applications of science.
1.Scientific discoveries have improved man's life in several fields. Which of the following is not mentioned in the passage?
A. medicine B. communication and transportation

One of the greatest sources of unhappiness, in my experience, is the difficulty we have in accepting things as they are．
When we see something we don’t like, we wish it could be different. We cry out for something better. That may be human nature，or perhaps it’s something ingrained(根深蒂固的) in our culture. The root of the unhappiness isn’t necessarily that we want things to be different．However, it’s that we decided we didn’t like it in the first place. We’ve judged it as bad，rather than saying, “It's not bad or good, and it just is it．”
In one of my books, I said, “You should expect people to mess up and expect things to go differently than you planned”. Some readers said it's too sorrowful to expect things to go wrong．However, it’s only negative if you see it as negative and judge it as bad. Instead，you could accept it as the way the world works and try to understand why that is．
This can be applied to whatever you do：how other people act at work，how politics works and how depressing the news media can be．Accept these things as they are，and try to understand why they’re that way. _It_ will save you a lot of sadness，because you’ll no longer say, “Oh, I wish bad things didn’t happen!’’
Does it mean you can never change things? Not at all. But change things not because you can’t accept things as they are, but because you enjoy the process of changing, learning and growing．
Can we make this world a better place? You can say that you’ll continue to try to do things to help others, to grow as a person, to make a difference in this world. That’s the correct path you choose to take，because you enjoy that path. Therefore, when you find yourself judging and wishing for difference, try a different approach: accept, and understand. It might lead to some interesting results．
1.The author believes that we feel unhappy maybe because ___________.
A. it is our natural emotion in the life
B. culture asks us to be different from others
C. everyone has their own opinions on things
D. we dislike something in the beginning
2. In Paragraph 4，the underlined word "it" refers to ____________．
A. acting well at work and in politics
B. feeling depressed for the news media
C. accepting and understanding what has happened
D. saying something negative when bad things come
3.In the last paragraph，you are advised _____________．
A. to help others and make a difference
B. to enjoy what you have to do in the work
C. to judge yourself and make a wish for you
D. to try a new way when making the world better
4.What is the main theme of the passage?
A. Expecting things to be different gives us hope．
B. Accepting can make our life happier and better．
C. Traditional culture becomes root of unhappiness．
D. Judging good or bad is important for our world．

To my family and friends,
I have just started my tour of the area badly affected by the war. Everything is going really well, so no 16. The land is beautiful but unfortunately it has a lot of 17 too. Let me 18.
Last week, 120 school girls were 19 by a gas leak（泄漏）. Most have recovered but six are still in 20. Even though the local government speaks about the 21 of education, most of the kids here only attend school for four hours a day if they are lucky. They are so excited and 22 to learn, but then have to 23 things like being attacked. Most of these kids are 24 and can’t afford a pencil or even paper. So I’m planning a trip to several schools to talk about 25 and to give these kids some of the 26 they need. That is where all of you can help. If you can 27 whatever school supplies you have available, that would be 28 appreciated.
I know how busy you are so thank you for taking the 29 to do this and I will post pictures of this 30 after I return.
Thank you again.

Of all the things that have effects on your future, I believe that personal growth is the greatest. Many people talk about sales growth, profit growth, and possession growth, but none of these will happen without personal growth. In fact I’d like to have you memorize a most important sentence. It is “The key to your future is you yourself.”
There are many things that will help you better your future. If you belong to a strong, dynamic（充满活力的）and progressive company, that will help. Good training will help. Strong leadership will help. If the neighbors stay civil（文明的）, that will help. If your relatives don’t trouble you, that will help…All these things will help. We can go on and on with the list; but remember, the things that I’ve covered above just play minor（次要的）roles in helping you reach a good future. The major cause doesn’t lie outside. It lies inside.
Strangely enough, when two different men work in the same company, the first person may earn $1,000 a month, while the second may earn $10,000 a month. What causes the difference when they have the same job, use the same tools, and get the same training?
The cause of the difference lies in believing, in trying, in accepting failures, in thinking, in a smile at people around, and in the ways of dealing with problems. All of these can be major causes of your good future. You can see all these come from inside. In fact, the real difference is you yourself. You are the key to your future. Teens are the most wonderful and important period in life. If you want a great future, begin to improve yourself from now on!
72. Among all the things mentioned, which one is the most important in the author’s opinion?
A. Sales growth. B. Profit growth. C. Possession growth. D. Personal growth
73. Which of the following may play a main role in influencing you future?
A. Being determined. B. Working in good companies.
C. Having rich relatives. D. Getting leaders’ help.
74. All may cause the two men’s different earnings EXCEPT that_______.
A. the second person buys expensive houses or cars.
B. the first person treats others badly.
C. the second man has a positive attitude to problems.
D. the first man gives up after failures.
75. The passage is mainly written for_____.
A. old people B. adults C. teenagers D. babies
