Growing Minds Need Greener Spaces
It is not a secret that spending time outdoors is good for us.The more we learn about the benefits of being in nature, the more sense it makes to get outside.
1.New research suggests that kids may learn better when they are surrounded by greener spaces.Green spaces are spaces filled with Vegetation-like trees,flowers and other plants.
But these days,outdoor time is competing for a child’s attention with indoor activities.Children may find it difficult to resist computers,television and electronic games.2.All these indoor activities can hurt a child’s physical and mental health.
Doctor Payam Dadvand and his team at the Centre for Research in Environmental Epidemiology in Barcelona study the environment effects on health and learning.
The researchers used information from satellites to learn how much green space surrounded each school.Over one year, the children took computerized tests for four times.3.They found that the children with higher contact with green space had better ability to memorize.They were also more attentive.4.More trees means less air pollution.
5.Lisa Freund is an expert in child psychology for the National Institute of Child Health and Human Development.She says more studies are needed to learn the Health and Human Development.She says more studies are needed to learn the reasons that vegetation in and around schools improves mental ability.
A.They measured memory and attention span.
B.This could be especially important for school children.
C.Approximately one half of the world population lives in cities.
D.The question of why green spaces affect learning is a new one.
E.The research suggests good air quality is the main reason for the results.

It is true that world population is growing, but this is not the cause of our current and future global problems. Believing this will cause us to ignore the real problem and risk long-term damage to our planet.
Let me start by explaining why overpopulation is a myth. For one thing, the UN Population Division regularly predicts population growth but provides a low variant (变量), medium variant, and high variant to factor in various possibilities. In the 2010 revision, their high variant suggests that the world population will be almost 16 billion in 2100, but the low variant predicts it will peak at 8 billion and decrease to just over 6 billion by 2100. In most cases, it is the low variant that has come true in the past, suggesting the same will be true of their future population predictions. In addition to this, the size of families is actually decreasing.
For another, if the Earth is overpopulated, there needs to be insufficient (短缺) food, water, and space for humans to live. However, Indian economist Raj Krishna estimates that India alone is able to increase crop produce to the point of providing the entire world’s food supply. The World Food Programme confirms that there is sufficient food grown to feed the world and there is the same amount of fresh water on the planet now as there was 10,000 years ago. So how is it possible that the number of people in the world is affecting our planet?
Therefore, it is not an increase in population but an increase in consumption that is a severe threat. Materialism and overconsumption are facts of life for everybody in the western world, as possessions reflect a person’s status in society and people strive to obtain happiness through owning the latest fashionable goods. Not only that, but waste is a common occurrence which has a huge effect on our resources. It is a sad truth that 80% of the world’s resources are currently used by just 20% of the world’s population.
Our overconsumption must be addressed now to make our lives more sustainable (可持续的) and avoid continuing the terrible damage to the environment we are causing. The key is education. If we do not work towards this but instead focus on the wrong issue, we may find ourselves living on a planet that can no longer sustain human life.
1.According to the author, what causes our current and future global problems?
A. The increase in population.
B. Shortage of food and water.
C. The fast growth of material needs.
D. Failure to protect the environment.
2.The underlined word “myth” in Paragraph 2 is closest in meaning to _________.
A. fact B. misunderstanding C. possibility D. uncertainty
3.The author stresses that _____.
A. people should save food and water
B. economists are making wrong predictions
C. wrong judgment leads to serious consequences
D. measures should be taken to reduce population
4.What is mainly discussed in the passage?
A. The real cause of global problems.
B. The severe effect of overpopulation.
C. Reasonable use of natural resources.
D. Methods to reduce overconsumption.

Scientists think that growing garden grass could be the secret to solving our energy needs, and we may soon be able to replace our gasoline with “grassoline”.
The team, including experts from Cardiff University in Wales, has shown that hydrogen can be taken from grass in useful amounts with the help of sunlight and a cheap catalyst (催化剂) — something that speeds up a chemical reaction without being used up.
It is the first time that this has been shown and it could lead to a sustainable (可持续的) way of making hydrogen, reported Asian News International. This could be an important kind of renewable energy because it is high in energy and it does not give out harmful gases when it is burned.
Study co-author Michael Bowker said, “This is really a green source of energy. Hydrogen is seen as an important future energy carrier as the world moves from fossil fuels to renewable energy, and our research has shown that even garden grass could be a good way of getting it.”
Cellulose (纤维素), which is a key part of plants and the biopolymer (生物聚合物) found in the largest numbers on the earth, could be a great source of hydrogen.
In its study, the team looked at the possibility of getting hydrogen from cellulose using sunlight and a simple catalyst.
This is called photocatalysis (光催化作用) and in it, the sunlight starts the catalyst, which then makes cellulose and water into hydrogen. The researchers studied the effectiveness of three metal-based catalysts, of which nickel (镍) especially interested the researchers, as it is a much more common metal than gold and palladium (钯) and it saves more money.
According to Bowker, producing hydrogen from cellulose using photocatalysis has not been studied in detail. The team’s research shows that large amounts of hydrogen can be produced using this method with the help of a bit of sunlight and a cheap catalyst.
The study shows that it is effective to use real grass taken from a garden. “This is important as it avoids the need to separate and clean up cellulose, which can be both difficult and costly,” said Bowker.
1.What are needed to get hydrogen from grass?
A.A catalyst and palladium. B.Water and cellulose.
C.Sunlight and a biopolymer. D.Sunlight and a catalyst.
2.Why is the new way of making hydrogen considered significant?
A.It is cheap, green and sustainable.
B.It is the best to produce the renewable energy.
C.It is more productive and efficient than other methods.
D.It can replace the way to make fossil fuels completely.
3.Why does nickel interest the researchers in making hydrogen from cellulose?
A.It can produce the largest amount of hydrogen.
B.It can avoid separating and cleaning up cellulose.
C.It is more common than other metals and costs less.
D.It works quicker than other metals during photocatalysis.
4.What does the author intend to tell us mainly in this passage?
A.Catalysts that could be taken from grass.
B.A new way of making hydrogen from cellulose.
C.The potential of hydrogen as a renewable energy.
D.The connection between hydrogen and photocatalysis.

You may think that sailing is a difficult sport, but it is really not hard to learn. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.
Let’s start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle to the boat. Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45°angle to the boat. It needs to be out far enough to catch the wind, but it shouldn't flap(摆动). It shouldn’t look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.
Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. When you’re tacking, you must always keep the sail inside the boat.
1.What should you consider first while sailing?
A. Sailors’ strength.
B. Wind directions.
C. Size of sail.
D. Wave levels.
2.What does the word “It” in Paragraph 4 refer to?
A. The sail. B. The wind. C. The boat. D. The angle.
3.What do you have to do when sailing against the wind?
A. Move in a straight line.
B. Allow the sail to flap.
C. Tack the boat.
D. Lower the sail.
4.Where can you probably find the text?
A. In a tourist guidebook.
B. In a physics textbook.
C. In an official report.
D. In a popular magazine.
