Becoming Bears (Kindergarten-2 grade)
By becoming baby bears, children learn from their “parent” to survive the seasons. Kids will find safety in the spring and learn kinds of food bears eat during the summer, and then create a cave for winter hibernation(冬眠). After learning the skills needed to survive, students will go out of the cave as an independent black bear able to care for themselves. (1.5-2 hours)
Whose Clues? (3-5 grade)
Kids will discover how plants and animals use their special structures to survive. Through outdoor study of plants and animals, kids will recognize their special structures and learn how they enable species to eat, avoid their enemies and survive. Using what they have learned, kids will choose one species and tell how they survive in their living places. (3-4 hours)
Winged Wonders (3-5 grade)
Birds add color and sound to our world and play an important ecological (生态的) role. Students will learn the basics of birds, understand the role birds play in food chains and go bird watching using field guides and telescopes. Students will do hands-on activities. Students will use tools to build bird feeders, allowing them to attract birds at home.(3-4 hours)
Exploring Your Watershed (6-8 grade)
We all depend on clean water. Examining how our actions shape the waterways around us. Go on a hike to see first-hand some of the challenging water quality problems in a city. Students will test the water quality to determine the health of an ecosystem.

Each year, 1.1 billion cans of beer are drunk by students aged 15-19 years old. Beer is the most common alcoholic drink among teens—81 percent of the drinkers had tried it. Beer is followed by wine with 63 percent, hard liquor(烈酒) with 53 percent and wine coolers with 35 percent.
When the young people are asked why they drank, the most common answer is that drinking is “something to do”. If a teen’s parents drink alcohol, the teenager is more likely to start drinking at an early age. Also, tens see all of their friends drinking alcohol so they think it is the must-to-do thing. Peer pressure is probably the hardest thing teens have to deal with. What’s more, teens often drink alcohol because it makes them feel older and cooler.
Researchers asked 56,000 students about their drinking habits and grades, to see how drinking might affect their grades in school. The results seem to be clear. Students who got a C level or lower tend to use three times as much alcohol as those who got B’s or A’s.
Alcohol use can be deadly. About 8,100 young people are killed per year in alcohol-related accidents. Eight young people die per day as a result of a drunk-driving accident. Between 50 and 65 percent of all teen suicides (自***) occur after the young people drink.
So you see, drinking the alcohol doesn’t always end up with a good time. The next time you try to push someone to drink or someone tries to push you to drink, please remember this. One drink can set the habit for life. Why not throw it away?
小题1:The reasons for teens’ drinking alcohol are mentioned EXCEPT that _______________.
A.they think it is cool to drink alcohol |
B.their parents set a bad example to them |
C.alcohol can make them happier |

A.Drinking alcohol makes students stupid. |
B.Good students never try alcohol. |
C.Drinking habits have something to do with IQ. |
D.Students with poor grades tend to use more alcohol. |
A.show the bad effect of drinking alcohol |
B.show how many teenagers drink alcohol |
C.tell teenagers not to try alcohol |
D.tell the reasons why teenagers drink alcohol. |

Since water is so important to us, it is very important that the water we use should be clean , Otherwise, we might get some of the diseases that are carried by water Many microbes are harmful ,They are so small that we cannot see them ,These microbes must be removed or killed before the water is not clean, people who drink this water may get these diseases, Thus , to provide people with clean water, the government purifies the water.
Purification is a long process and consists of three stages: storing ,purifying and distributing ,The first stage is storing , Man-made lakes called reservoirs are used for this purpose ,Water from the rains ,other lakes, streams and rivers is collected in the reservoirs ,This water is usually dirty and muddy.
In the second stage shich is purifying , water from the reservoirs is filtered in a special pond, Stones, sand and other unwanted tiny things are caught in it, After that, tiny microbes are still present in the water ,These microbes are removed by “airing ”the water and by adding a chemical substance called chloring(氯)to the water ,This kills all the microbes in the water ,A fter this the water can be safely used for drinking.
The third stage is the distribution of the purified water to homes ,hospitals, offices ,factories and other places, This is done through a network of pipes of various sizes, These pipes must be make of a suitable material.
小题1:From Paragraph 1, we can learn that
A.Rain has contained gases when it forms in the clouds |
B.Dust and microbes are dissolved in rain when rain falls on the ground |
C.The closer rain is to the ground, the more impure things it contains |
D.Sand and mud are things rain collects when it falls through the air |
A.All the microbes in water are harmful so water must be purified |
B.some diseases can spread through drinking water if it is not clean |
C.Water is safe to drink if only harmful microbes are removed from it |
D.it is the govrnment’s responsibility to make drinking water clean |
A.It is used through the whole process of purification |
B.Only rain water can be collected and stored in it |
C.Water collected can be stored and filtered in it |
D.Water from them contains a lot of impure substances |
A.to air the water | B.to catch tiny things |

The researchers looked at data from ,11,499 children who took part in a large study, It showed that 507 who were slow to gain weight in the first eight weeks of life recovered fairly quickly and had almost caught up by age 2. Another group of 480 who were slow to gain between eight weeks and nine months continued to put on weight slowly until they were seven years ,but then had a sudden increase and caught up by age 13, The different pattems of recovery between the two groups were likely due to different reasons for slow weight gain ,the researchers said, All the children were still lighter and shorter than their peers by the time they were teenagers ,but within the normal range.
The findings highlight the importance of monitoring a baby’s weight and height gain during the first few weeks and months ,but not creating anxiety with parents of slow-growing babies, said the study leader Prof Alan Emond from the University of Bristol.
“In the past, a lot of parents have been caused unnecessary anxiety by heaith professionals and this is a positive and reassuring message.”He said in many cases of slow growth where children do not follow the standard’curve’(曲线)it is just because they are following their genetic potential.
Dr Simon Newell, vice-president of the Royal College of Paediatrics and Child Health, said he broadly agreed with the concluslons of the researchers but stressed that poor weight gain was something that needed to be monitored closely, “I would encourage parents to use growth charts but if measurements show your baby is smaller than averager it may be completely normal, ”he said.
小题1:What can we know from the findings of the research?
A.All the cases of slow weight gain in the first months of the babies’ lives are caused by the same reason |
B.Slow-growing babies will have the same height and weight with their peers by age13 |
C.Many cases of children whose growth don’t meet the growing standard curve cannot be treated as abnormal |
D.The findings won’t cause parents’ anxiety so monitoring a baby’s growth from his/her birth is unnecessary |
A.It’s important to monitor a baby’s weight and height gain for new parents |
B.New parents should feel anxious about their baby’s weight and height gain |
C.Researches still couldn’t find the reasons for slow weight gain |
D.All the children’s weight and height became normal by age 13 |
A.Making sure something is certain to be true |
B.Making someone calmer and less anxious |
C.Confirming something is to happen again |
D.Being sure that someone can be attracted |
A.To some degree, growth charts can help parents monitor their babies’ weight gain |
B.It’s abnormal for babies are smaller than average |
C.He agreed with the researchers completely |
D.Babies’ weight gain can only be monitored and measured by using growth charts. |
A.tell us how to help babies grow faster |
B.explain why babies are gain weight slowly |
C.report on the findings of a research |
D.reduce the anxiety of some parents |
Hydrogen is one of the building blocks of the universe ,Our own sun is basically ,a big ,dense cloud of the stuff ,And hydrogen can be used to create electricity for power ,heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time , It does not exist as a material on its own ,but is always part of something else, So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas , As oil will start to run out in around the year 2030.,it makes sense to produce as much hydrogen as possible as soon as we can ,But natural gas supplies will also begin to run out soon after, Another source is needed.
Researchers are now using electricity to make water into hydrogen ,Companies are working on the problem in their own areas ,The first commercial hydrogen ,”fuel cells”for computers and mobile phones have already come on to the market ,Auto companies have also invested over US $2billion in the production of hydrogen fuelled cars
Thd nations of a hydrogen fuelled planet would not fight over evergy recourses, There would be a great reduction in pollution ,The only by-product of creating hydrogen is pure drinking water—something that is very scarce in many parts of the world ,But that is not where the good news ends, Once the costs of producing hydrogen have been brought down ,it will possibly provide power for a third of the Earth ‘s population that has no electricity.
And electricity creates wealth, In South A frica over the last decade there has been a large programme of electrification, Thanks to the programme , people do not have to spend their days looking firewood to burn for heat, And with electric light , they can work long into the night.
Some scientists see radical changes in the way the human race co-operates, Hydrogen creates clectricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it ,Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web”, which it supplies with electricity ,A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car, Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away, But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to edn oil dependency and spend more time and money on hydrogen resource, So maybe the threat of war is not a completely bad thing for the future of the human race.
小题1:What does the underlined word “it”in the last but one paragraph refer to?
A.wealth | B.hydrogen | C.electricity | D.fuel |
A.It has by-products |
B.It has to be separated from other materials |
C.It will make energy too cheap |
D.It is too far away from us |
A.To tell us that we produce energy while using hydrogen power |
B.To tell us that hydrogen power does not produce pollution |
C.To show hydrogen power can stop war |
D.To show hydrogen power is cheap |
A.skeptical | B.negative | C.indifferent | D.positive |
A.war and energy |
B.the future of hydrogen as an energy resource |
C.the disadvantages of oil |
D.How to end war |
