If you have a dog, you know the damage they can do to a garden. They dig under bushes, pound out a dirty path by the fence, or even eat your delicate flowers.1.. In spite of that, we still love them. That’s why I put together these dog-lover tips for gardening.
Before you start planting, it’s important to note your dog’s personality.2. . So is your dog a patroller, a digger, or a chewer? Get a general idea of the most common behaviors of your dog and you’ll have a good idea of what to plant for.
If your dog patrols the yard----constantly circling the yard, you need to plant around it. 3.. Keep high-traffic and patrolling zones open. Plant tall plants that will grow above your dog. Containers or raised planter boxes are a great option if you want to plant more colorful and delicate flowers.
4., add a low or high fence around an area you don’t want your dog to dig. Cover digging areas is also a neat trick. Another choice is a sandbox because sand doesn’t get muddy. Dries quickly, and shakes off easily. If you don’t want it where your dog is already digging you can try putting the sandbox in a shady area of the yard.
If your dog likes to chew, pay special attention to his safety. Certain plants can be poisonous and create health problems for your dog. Just go to some websites for information about poisonous plants for dogs. 5..
A.If your dog is a digger
B.Don’t plant where your dog always goes
C.When you prevent your dog from chewing
D.We shouldn’t have to yell at them every time they are in the yard
E.They will give you more on each plant so you can do your research
F.Different animals have different abilities, and no two dogs are the same
G.They are quick to turn their beautiful garden into their own personal playground
Ants are truly incredible creatures. In addition to talents like predicting earthquakes and saving themselves from drowning during floods, the hardworking insects go all out to protect their own comrades, often carrying the wounded back to the nest to heal. Now researchers have discovered ants who explode and sacrifice themselves to save their nests from attackers.
Although scientists have known about the existence of exploding ants since 1916, they were first found in the rainforests of Borneo in Southeast Asia by an international team of researchers led by Alice Laciny, a graduate student at the Natural History Museum, Vienna.
The researchers noticed that during the day, when the ants went outside to look for food, they would be closely monitored by a small army of “guards”, who touched each member as it went in and out of the nest. Upon running into an attacker, the guard ant would angle its back part towards the attacking creature and shrink its stomach. This caused the ant’s body to explode and release a yellow, deadly goo(粘状物), which instantly killed the attacker.
The ability to explode, however, was not universal among the species and appeared to be possessed only by minor worker ants, usually the smallest ants of the nest. Even more interesting was that while the minor members were blowing themselves up, the large worker ants with oversized plug-shaped heads, placed barriers at the nest’s entrance to prevent other potential enemies from entering.
While the defense measure may sound extreme, Tomer Czazkes believes it is necessary. The behavioral ecologist at Germany’s University of Regensburg says since the insects live in large groups, they are a natural and easy source of food for ant eaters. They, therefore, have to find ways to protect themselves. Ants are not the only insects known to conduct this type of voluntary-sacrifice. Older termites(白蚁 ), who have lost their abilities of nesting and finding food, also explode onto their enemies.
Next, the researchers hope to find out the make-up of their yellow goo, how they use their explosion to take down larger attackers and so on.

We already know that exercise is good for our bodies. Daily exercise fights the loss of muscle tone and flexibility that tends to increase slowly with age. And it turns out that it has the same fountain-of-youth effects on our brains.
Studies show that over time our minds also become less flexible and nimble. We lose the ability to process new information or switch between mental tasks quickly — and now we know why.
A recent study examined nearly 100 individual studies on exercise and brain function and discovered exercising an average of 52 hours over six months is "associated with improved cognitive(认知的)performance in older adults with and without cognitive damage." The type of exercises that are beneficial include aerobic, strength-training and mind-body.
In previous studies, researchers from Japan's University of Tsukuba wanted to explore this idea by looking at the effect of exercise on this weakening of the brain. They tested the oxygen ability of 60 Japanese men between the ages of 64 and 75 who did not show any signs of dementia or other mental symptoms. Next, they looked at the brain activity of each man as he completed a mental task. They found that the fitter a participant was, the less brain activity he used to complete the tasks when compared with his out-of-shape peers(同龄人).
Although much research is focused on how exercise may benefit an aging brain, exercise offers brain health benefits at almost any age, and this includes children. A review of 14 studies showed that more physically active schoolchildren do better academically. Exercise actually causes your brain to grow in size. So get moving and keep moving for best results.
1.Which of the following best explains “nimble” underlined in Paragraph 2?
A.Intelligent. B.Dull. C.Unique. D.Simple.
2.What can we infer about the participants’ less-active peers?
A.They had significant brain advantages. B.Their brains were younger than their age.
C.They didn’t have to attend health classes. D.Their cognitive performance would decline.
3.How does the author support his idea?
A.By making comparisons. B.By analyzing study results.
C.By describing the processes. D.By telling his own experiences.
4.What’s the main idea of the text?
A.Exercise is beneficial for your bodies.
B.Exercise is especially good for the old.
C.Exercise can benefit your brain health.
D.Exercise may lower your risk of mental problems.
James Harrison is called “The Man with the Golden Arm”. The Australian man has saved the lives of more than 2.4 million babies by donating blood nearly every week for 60 years.
At the age of 14, Harrison had an 11-hour operation to remove a lung. “ I received 13 units(liters) of blood and my life had been saved by unknown people,” Harrison said. “When I’m old enough, I’ll become a blood donor.”
That is exactly what Harrison did. Soon afterwards, doctors told him that his blood contains a rare antibody that could help mothers who have rhesus disease, a condition where a pregnant woman’s blood attacks the blood cells of her fetus(胎儿). In worst cases, it can result in brain damager or death for the baby, and until about 1967, thousands of babies were dying each year in Australia.
Before long, researchers had developed an injection(注射剂), called Anti-D, using Harrison’s donated blood. Because about 17 percent of pregnant women in Australia require the Anti-D injections, the blood service estimates Harrison has helped 2.4 million babies in the country. At age of 81, he had already passed the age limit allowed for donors, and the blood service had decided Harrison should stop donating to protect his health.
Harrison was awarded the Australian Medal of Honor in recognition of his extraordinary efforts and generosity, but he doesn’t consider himself a hero. He’s now donated his blood 1,173 times, which gained him a Guinness World Record. But in all those times of giving blood, he’s never once watched. “I look at the ceiling or the nurses, maybe talk to them a bit. I can’t stand the sight of blood, and I can’t stand pain.”
1.What contributed to Harrison’s becoming a blood donor?
A.The rare antibody in his blood B.His gratitude to the blood donors
C.The request from the blood service D.His pain during the removal of his lung
2.What’s Anti-D used to do？
A.Save babies by giving them injection B.Protect babies from common illness
C.Cure pregnant mothers with rhesus disease D.Prevent women’s blood from being attacked
3.What does Harrison hold the Guinness World Record for?
A.The age among blood donors B.The amount of blood he donated
C.The number of donations he made D.The number of babies he saved by donating
4.What does the author think of Harrison?
A.He is kind and curious B.He is generous and modest
C.He is selfless and shy D.He is sympathetic and cautious
