Food is extremely important to us human beings and rice is one of the main food in the world. Australian researchers have discovered a way to genetically engineer rice which would provide significant health benefits to more than half the world’s population.
A study undertaken at the University of Tasmania, published in a respected journal of the National Academy of Sciences, discovered a method to increase the resistant starch (抗性淀粉）content in rice, making it more digestible and leading to lower rate of diabetes (糖尿病）and overweight.
Steven Smith, the lead author of the study and a foreign expert for the Chinese government who has been appointed to work on crop improvement projects by the Chinese Academy of Sciences, said increasing the higher resistant starch content gave this “designer” rice many added health benefits. “We have discovered that we can increase the amount of resistant starch in cooked rice, which could provide health benefits for a large number of people in Asia and beyond,” Smith said in a media release on Friday. “The same approach can be adapted for use in other cereals, including wheat. Not only can it have benefits for diabetes and obesity, but also for disorders of the bowel(肠）including cancer.”
Rice is the main food for more than half the world’s population, providing much of the world with most of their calories. Smith said that as the rate of diabetes and obesity in Asian countries continued to grow, his “designer” rice could provide a way to limit health problems.
“Not only does resistant starch reduce the possibility of a ‘sugar hit’ but it also reduces the appetite and promotes the growth of the healthy germs.” Smith said.
Smith divides his time between the University of Tasmania and his research lab in Beijing where he hopes to make significant advance in sustainable (可持续的）living.
1.What do we know about the study?
A. It is part of Chinese crop improvement projects.
B. It will have a significant effect on crop researches.

A. exists in large amounts in cooked rice

C. is helpful in digestion and lowers the rate of overweight and diabetes
D. increases people’s appetite and improves the growth of healthy germs
3.The underlined word “it” in Paragraph 3 refers to _________.

高三英语单项填空简单题查看答案及解析
Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the existence of creatures and even whole societies beyond our everyday lives.
This sense of wonder is universal. Look at the efforts that scientists have made to find out whether life of some kind exists on Mars, and the popularity of fantasy(幻想) literature or movies like The Lord of the Rings. This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist all around us?
Human beings, as biologists have suggested, possess an inborn desire to connect with and understand other life forms. However, people, especially in big cities, often lead rather isolated lives. In a study of British schoolchildren, it was found that children by age eight were much more familiar with characters from television shows and video games than with common wildlife. Without modern technology, a small pond could be an amazing world filled with strange and beautiful plants, insects, birds, and animals. When we lack meaningful interaction(交互) with the world around us, and sometimes even with our families and friends, we seek to understand and communicate with things that exist only in our imaginations or on a computer screen.
The world of make-believe is not necessarily bad. But when the world of fantasy becomes the only outlet(出路) for our sense of wonder, then we are really missing something. We are missing a connection with the living world. Other wonderful worlds exist all around us. But even more interesting is that if we look closely enough, we can see that these worlds, in a broad sense, are really part of our own.
1.The popularity of The Lord of the Rings proves________
A. the close connection between man and the fantasy world
B. the wonderful achievements of fantasy literature
C. the fine taste of moviegoers around the world
D. the general existence of the sense of curiosity
2.What can we infer from the underlined sentence in Paragraph 3?
A. People are far less familiar with the world of fantasy.
B. The world around us could serve as a source of wonder.
C. The world of fantasy can be mirrored by a small and lively pond.
D. Modern technology prevents us from developing our sense of wonder.
3.If our sense of wonder relies totally on the world of make-believe, we will________
A. fail to appreciate the joy in our lives
B. be confused by the world of make-believe
C. miss the chance to recognize the fantasy world
D. be trapped by other worlds existing all around us
4.What is the main purpose of the passage?
A. To show us the hidden beauty in our world.
B. To warn us not to get lost in the fantasy world.
C. To argue against the misuse of the sense of wonder.
D. To discuss the influence of the world of make-believe.

CORAL reefs are,in fact,a necessary part of our ecosystem and provide opportunities for human beings to gain a better understanding of the ocean.Unfortunately,they're also disappearing faster than ever.
According to a warning by the US National Oceanic and Atmospheric Administration(NOAA) on Oct.8,the world is in its third recorded global coral bleaching（白化）since 1998 and 2010.This means no place with coral has been spared,as coral reefs are coming into contact with increasingly warm seas,which is leading to them dying off in large numbers.
Coral bleaching is like human cancer.It happens when corals are under stress from changes in light,nutrients,or temperature.This causes the coral to drive away the symbiotic algae（共生藻类）,living within their tissues（组织）, which play an important role in providing food for coral while making it colorful.Without the algae,coral reefs become pale and weak.In some cases they are not able to recover and eventually die off.
The current coral bleaching event started back in late 2014 and continued into this year with no signs of stopping.The BBC reports that 35% of coral reefs in the world will likely be affected,and an estimated 4,633 square miles (about 120,000 square kilometers) of coral reefs could die.
The loss of coral reefs is no small matter.Although they only take up 0.1% of the ocean floor,coral is home to about 25% of marine life.This isn't just a problem for divers and fish,as Eakin pointed out.Coral reefs are important globally,he added,as they protect shorelines,produce money in tourism,and help provide food for 500 million people worldwide.So people cannot overlook the environmental,economic and social effects of the loss.
The NOAA warning about coral bleaching came just about two months before a global climate summit（峰会）in Paris,where hundreds of world leaders will attempt to work our a plan to fight climate change.
Oceans will be a key subject during the summit,and Eakin says there's an "absolutely urgent need" for action.

高三英语阅读理解困难题查看答案及解析
Whether in your life or work, the following things are not the reasons for you to feel embarrassed. It's OK and just move on.
1. Mistakes while learning
There will be times when you have people above you(a boss) or even next to you(a coworker) that will get really annoyed with you for“ruining" something "important". 1. Even if you make mistakes and get a punishment, persevere and push on. You do not need to be embarrassed for learning from your mistakes.
2.Food choices
People are different and have different taste buds（味蕾）.Whether it is healthy or not, food is a choice and it is part of life. 2. You do not need to be embarrassed for food you do or do not like. Tell them, "It is a personal choice I have made, and I am committed to it.”
3．Your past
Allowing positive experiences to define, limit, improve, and outshine（凸显）you may cause you to be caught up in the past and unable to truly live in the present. Whether your history is positive, negative, or somewhere in between, don't hold on to the negative experiences and let it reflect your current behavior， 3.
4. The clean lines of your car／home／workspace
When everyone gets in the car, you realize your Starbuck bags are still on the floor. So what? Think about it this way: everyone has a"messy" aspect of their life. Maybe their home is completely clean, but the relationship with their spouse（配偶）is messy. Someone's car gets washed once a week, but his/her work life could use some help. 4. We don't apologize to others about our personal limitations. By being outwardly embarrassed, it only brings more attention to the fact!
5. Putting yourself first

You will feel much better in the long run if you are honest with them and yourself. If you're not up to a voluntary duty, you don't have to be. You can politely refuse the person's request.

A. It is simply a personal choice that people make for their own reasons.
B. It is okay to be selfish from time to time.
