Do you know mulch? Mulch is a protective cover of material that is spread on top of soil. It is usually made out of organic material, like crop waste. Farmers may keep the remains of corn or other crops on top of the soil. This creates mulch on the soil surface. The plant remains help protect the soil against wind and water damage. Mulching is one of the best things people can do for their plants. It also helps keep the soil from getting dry, and reduces the need for watering plants. It also limits temperature changes in the soil. And it stops unwanted plants, or weeds, from growing.
Organic mulch improves the condition of soil. As the mulch breaks down, it provides material which keeps the soil from getting hard. This improves the growth of roots and increases the movement of water through the soil. It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants. It also provides good environment for earthworms and other helpful living things in the soil.
It is easy to find organic mulch materials. Cut-up leaves and small pieces of tree bark can be used. Grass cuttings are also a good mulch for plants. Mulch from news- papers works well in controlling weeds.
The best time to add mulch depends on your goal. Mulch provides a thick barrier between the soil and the air. This helps to reduce temperature changes in the soil. As a result, mulched soil will be cooler than other soil in the summer. In winter, the mulched soil may not freeze as deeply as other soil. The best time is after the ground has frozen, but before the coldest weather arrives. Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter. Delaying the spreading should prevent this problem. The animals will probably find another place to live.

When you get a cut, you cover it with a bandage. How do you know when to change it? Maybe you just wait until it’s wet or dirty. But when people have long-term or chronic (慢性的)wounds that take months to get better, changing bandages too early or to late could make healing take even longer. Changing the dressing on a wound too often can provide an opportunity for infections to get in. But if a bandage gets very wet very quickly from the inside, it might be filling with pus (脓)--a sign an infection has begun. Judging just when to change is important.
Chronic wounds are common in people who are older or who have certain health conditions. Chronic wounds affect around 6.5 million people per year in the United States. When Anushka Naiknaware, 13, learned about chronic wounds, she decided to make a device that could alert a person when it’s time to change their bandages.
After a lot of trials and errors, the teen settled on a design that used an “ink” filled with carbon nanoparticles(纳米粒子). The teen loaded her ink into a printer cartridge (墨盒) to print onto her special paper, which was to be made into bandage. Well, actually, Anushka loaded her ink into many, many printer cartridges. Just changing a printer cartridge isn’t easy, and filling one is even harder.
The small printed papers cost only 5 to 10 cents, Anushka estimates. The Bluetooth sensor is more expensive, but the teen notes that it could be used over and over again. She also knows there is a long way to go before her design can help patients. It hasn’t been tested on a real person yet. “You have to make sure everything works perfectly,” she says.
1.What can we learn from Paragraph 1?
A. The right time to change bandages is significant.
B. Chronic wounds with a bandage won’t heal.
C. Changing bandages often will help cure wounds.
D. Older people are victims of chronic wounds.
2.What does the underlined word “alter” in Paragraph 2 probably mean?
A. Assist. B. Remind. C. Comfort. D. Control.
3.What is stressed in Paragraph 3?
A. The shape of the printer cartridge.
B. The discovery of materials of the bandage.
C. The amazing features of carbon nanoparticles.
D. The difficulty Anushka had with her invention.
4.What could be the best title for the text?
A. A bandage is widely used for injuries.
B. A girl decides to treat chronic wounds.
C. A bandage that can tell the changing time.
D. A teen invents a device that heals wounds.

Do you know of anyone who uses the truth to deceive (欺骗) ? When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture.
For example , some might say, "I just won a hundred dollars on the lottery (彩票) . It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars! "
This guy's a winner, right? Maybe, maybe not. We then discover that he bought $200 worth of tickets, and only one was a winner. He's really a big loser!
He didn't say anything that was false, but he left out important information on purpose. That's called a half-truth. Half-truths are not technically lies, but they are just as dishonest.
Some politicians often use this trick. Let's say that during Governor Smith's last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents says, "During Governor Smith's term, the state lost one million jobs!" That's true. However, an honest statement would have been , " During Governor Smith's term , the state had a net gain of two million jobs. "
Advertisers will sometimes use half-truths. It's against the law to make false statements so they try to mislead you with the truth. An advertisement might say, "Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache. " It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.
This kind of deception happens too often. It's a sad fact of life: Lies are lies , and sometimes the truth can lie as well.
1.How much did the lottery winner lose?
A. One hundred dollars. B. Two hundred dollars.
C. Three hundred dollars. D. Four hundred dollars.
2.We may infer that the author believes people should___________.
A. buy lottery tickets B. make use of half-truths
C. not take anything at face value D. not trust the Yucky Company
3.What do the underlined words " net gain" in Paragraph 5 mean?
A. final increase. B. big advantage.
C. large share. D. total saving.
