Like other holometabolous insects, the butterfly's life cycle consists of four parts, egg, larva, pupa and adult. Most species are diurnal. Butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. Butterflies comprise the true butterflies (superfamily Papilionoidea), the skippers (superfamily Hesperioidea) and the moth-butterflies (superfamily Hedyloidea). All the many other families within the Lepidoptera are referred to as moths. .

Spare that Spider 不要伤害蜘蛛
How much of each year do spiders spend killing insects? Why, you may wonder, should spiders be our friends? Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour(吞吃) our crops and kill our flocks(牲畜), if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beasts who eat insects but all of them put together kill only a fraction (零头)of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, spiders never do the harm to us or our belongings.
Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always has eight legs and insect never more than six.
How many spiders are engaged in this work? One authority on spiders made a census (统计调查)
of the spiders in grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre; that is something like 6,000,000 spiders of different kinds on a football pitch.(足球场)
Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with (不满足)
only three meals a day. It has been estimated(估计)that the weight of all the insects destroyed (摧毁)by spiders in Britain in one year would be greater than the total weight of all the human beings in the country.
Questions:
Do you think spiders should be a kind of insects? Why?
Are spiders friends or foes of human being? Why?
It is estimated that there are almost ____ spiders on a grass land as large as a football pitch in south England.
A. 2,250,000          B. 6,000,000     C. 8,250,000

科普英语低年级组授课讲义
than a back-and-forth motion. Grip the toothbrush like a pencil so you won't scrub too hard.
4. Drink a cup of tea every day. Flavonoids8 and other tea ingredients seem to prevent harmful bacteria from sticking to teeth, and also block production of a type of sugar that contributes to holes. Tea also contains high amounts of fluoride.9
5. Throw away your toothbrush or change the head of your electric toothbrush at least every two to three months. Otherwise, you're just transferring bacteria to your mouth.
6. Use alcohol-free mouthwash to wash away bacteria. Most over-the-counter mouthwashes have too much alcohol, which can dry out the tissues in your mouth, making them more affected by bacteria. Some studies even suggest a link between mouthwashes containing alcohol and an increased risk of oral cancer. To be safe, don’t drink alcohol when it comes to choosing a mouthwash.
7. Clean your tongue with a tongue scraper10 every morning to remove tongue plaque and freshen your breath. One major cause of bad breath is the buildup of bacteria on the tongue, which a daily tongue scraping will help banish.11 Plus, using a tongue scraper is more effective than brushing your tongue with a toothbrush, says Dr. Katz.
8. Even if you're a grown-up, avoid sugary foods. Sugar plus bacteria equals oral plaque. Plaque, then, leads to bleeding gums, tooth decay, and holes. Plus, the acid in refined sugars and carbonated drinks dissolves tooth enamel.12
9. Instead, eat "cleaning" foods. Foods that are firm or crisp13 help clean teeth as they're eaten. We already mentioned apples (otherwise known as nature's toothbrush); other choices include raw carrots, celery, and popcorn. For best results, make "cleaning" foods the final food you eat in your meal if you know you won't be able to brush your teeth right after eating.
10. Gargle with apple cider vinegar14 in the morning and then brush as usual. The vinegar helps remove stains, whiten teeth, and kill bacteria in your mouth and gums.
11. Brush your teeth with baking soda once a week to remove stains and whiten your teeth. Use it just as you would toothpaste. You can also use salt as an alternative toothpaste. Just be sure to spit it out so it doesn't count as sodium15 intake! Also, if your gums start to feel pain, switch to brushing with salt every other day.
12. Practice flossing with your eyes shut. If you can floss without having to guide your work with a mirror, you can floss in your car, at your desk, while in bed, and before important meetings. In which case, buy several packages of floss and scatter them in your car, desk, purse, briefcase or nightstand.
13. Keep rubber bottle openers and a small pair of scissors in your purse or desk drawer. That way, you won't have to use your teeth as tools, which can damage them. In fact, never, ever use your teeth as tools for anything except eating.

Notes:

1.        gum  n. 齿龈,口香糖。
2.        periodontal adj. 牙周的。
3.        periodontitis  n. 牙周炎。
