21、 A little battery puts out a little bit of electricity, so you can use it safely for your experiments. But the electricity that comes through the wires in your house or school is much more powerful. 【1】 .
Inside the walls where you live or study, there are big wires that carry electricity. When you plug in a light or radio or other electrical appliance, you are putting the light or radio in the path way of the electricity. You have heard adults warn, “ 【2】，‘ Now do you know why? If you did, you would become part of the electrical path way.
【3】 The electrical current coming through the wires to the wall plug is so strong that it would hurt a lot if you stuck your finger in the plug. Put your finger in there and it could be you, rather than the light bulb, that becomes part of the electrical path way. And that would hurt!
What if you held a piece of metal, like a fork or knife, and stuck it into the wall plug? Don't do it. Why? It's because metals also conduct electricity. 【4】
Don't touch any electrical appliance when you are wet. Can you think why? It's because water is a good conductor of electricity. When your hands are wet or when your body is in a bathtub full of water, the electricity could flow right through you and give you an awful shock, or even kill you.
Electricity is very useful, but it can be dangerous. 【5】If so, electricity can better serve you, instead of hurting you.
A.Life is precious!
B.So stay away from wires.
C.Be careful, be safe and be smart.
D.And you would get a terrible shock!
E.Don't stick your finger into the wall plug.
F.Therefore, keep in mind some safety rules.
G.Your body is a pretty good conductor of electricity.
22、There are well over a hundred firefly species in North America, and the twinkling insects are a special part of many childhood summers.
Research into firefly populations is sill in its early stages, but over the past few years, alarm bell have been ringing about the disappearance of fireflies around the world. A new survey of firefly researchers reveals what are three of the most likely causes, and agriculture is behind at least two of them.
The decline of firefly populations hasn't been finally measured. But the scientists, echoed by anecdotal (轶事的) evidence from those with formerly firefly-studded backyards, have noticed a decline. They mentioned thee major possible reasons for the firefly decline: Habitat destruction, pesticide (杀虫剂) use, and artificial light pollution.
Increasing expansion of agricultural land, especially in places like the Amazon rainforest, is considered the largest stimulus of habitat destruction. Many firefly species live in areas that are being destroyed for purposes of agriculture, especially in tropical (热带的) environments that are completely destroyed for palm oil plantations.
Pesticides, on the other hand, clearly have an agricultural link. Firefly. org notes that no studies have been done specifically to examine the effects of common insecticides on fireflies, but there's evidence that raises concerns. One study indicates that common lawncare insecticides are dangerous to common insects found in lawns, including firefly larvae (幼虫), which do not fly. Another finds that insecticides can be dangerous to some of the invertebrate species, like earthworms, that the firefly larvae eat.
Artificial light pollution is trickier; research indicates that artifial light can mess with the firefly's ability to mate, which they do largely with their blinking lights. It's not clear how much artifial light pollution comes from agriculture, but some studies suggest that farming does create artificial light.
There's lots of work left to be done to figure out exactly what's going on with fireflies. But what does seem clear is that agriculture is at least tied into their decline.
【1】What does the underlined word "stimulus" in Paragraph 4 mean?
A．prevention
B．cause
C．part
D．consequence
【2】What does Paragraph 5 mainly talk about?
A．The history of Firefly. org.
B．The decline in firefly populations.
C．The effects of common insecticides.
D．The link between pesticides and agriculture.
【3】Artificial light is responsible for the decline of fireflies in that ________.
A．it causes harm to fireflies' mating ability
B．it causes the failure of larvae's flying ability
C．it causes fireflies to lose their blinking lights
D．it causes fireflies to be caught by humans easily
【4】What can be a suitable title for the text?
A．Fireflies are a special part of our childhood summers.
B．The decline of firefly populations concerns the scientists.
C．Agriculture is partly to blame for the fireflies' decline.
D．Effective ways have been taken to prevent the fireflies from declining.
23、 About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?
Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is!
Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in tur consumed by larger animals. These food chains are delicately (微妙地) balanced.
The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.
Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most counties have introduced fishing restrictions (限制) to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!
【1】From the passage, we learn that _________.
A.most fish and sea animals live at the surface of the seas
B.it is very difficult to break the balance of a food chain
C.over-fishing has caused the decrease in fish stock
D.it won’t be long before the problems concerning oceans will be solved
【2】What does the underlined phrase “cope with” mean in Chinse?
A.处理 B.保护 C.增加 D.检验
【3】Which of the following is NOT a way being used to protect oceans?
A.The use of international agreements.
B.Forbidding fishing to protect fish socks.
C.The use of new techniques.
D.Raising people’s awareness of the need to protect oceans.
【4】What would be the best title of the passage?
A.The Importance of Sea Water
B.Life in the Oceans
C.How to Protect Food Chains
D.How to Deal with Seawater Pollution
24、 A young American doctor was sleeping when suddenly his doorbell began to ring. It was already midnight, but what could the doctor do? He had to get up, put on his coat and go downstairs.

26、IV. Summary Writing
Take Care of Your Spine (脊柱)
The spine stands at the center of your health, providing your body with structure and support. It also contains your spinal cord, a massive collection of nerves that sends electric signals from the rest of your body to your brain. Therefore, it’s important to take care of it.
Maintaining your good posture is one of the most important things you can do to keep your spine healthy. Proper posture means standing or sitting while keeping your spine straight, except for its natural curves. Posture comes into play even when you’re asleep. Sleeping on your side puts less stress on your spine than most other positions. Having a comfortable bed is also very important as sleeping in a position that isn’t comfortable can leave your back feeling sore the next day.
Exercise is also an important factor in the health of your spine. Staying still for too long—even if your posture is good—can be hard on your back. Especially if you work at a desk most of the day, it’s important to get up and stretch periodically. Stretches can help the muscles around your spine relax and allow bones to shift into better positions. Strength exercises with light weights or bodyweight exercises like pushups can also help by strengthening the muscles around your spine. However, don’t overdo the exercise, as repeated motions can hurt the muscles around your spine.
Your diet also affects the health of your spine because many vitamins are necessary for bones and nerves. In particular, B vitamins help keep nerves healthy, so you may want to consider taking a supplement (补充物). Another important factor is vitamin D, which is essential for strong bones, but it’s also absorbed from sunlight, so it may help to do some of those back exercises outside.
