“I bet it is
Anna grasped Betty’s sweaty palm,
“Will it bite us?” Betty asked hesitantly.
Clare answered confidently, “No, it won’t. It’s probably here because of the weather. Look outside! It’s
Suddenly, Anna screamed again, “There it is! I see it!” She

3 . As I look out of the window, an icy wind blows oak leaves across the yard. The stove in the living room has been maintaining a temperature that keeps my family comfortable through this winter’s temperature swings.
Plants naturally lose water from leaves through a process called transpiration (蒸腾作用). As a result, the plant’s roots take up water from the soil to replace what was lost.
Since light levels are lower in winter and plant growth slows, houseplants typically have little need for fertilizer during winter months.
A.It is not recommended to fertilize. |
B.Eventually, the soil will become dry. |
C.Wait until late winter/early spring to fertilize. |
D.It may change the amount of light reaching your plant. |
E.There are two additional considerations for where to place houseplants. |
F.You should water when the soil feels dry to the touch one-half-inch deep. |
G.While this may be good for the family, it may not be so for my houseplants. |
4 . Scientists in Australia thought they had developed a new tracking device to help them monitor magpies, but these intelligent birds had other ideas.
Initially, researchers planned a pilot study to learn more about the movements and social dynamics of magpie. The study was also designed to test the effectiveness of a new tracking device that would fit on small birds. “Instead, the birds outsmarted us,” explained Dominique Potvin, a zoologist at the University of the Sunshine Coast.
Most trackers are too big to fit on small sized birds, and small trackers tend to be limited when it comes to data storage, battery life, and reusability. The new trackers, which weighed less than one gram, would charge and send data wirelessly without needing to recapture the birds. They were attached to a rigid belt that could only be released with a magnet. The design was meant to be durable, except for a weak point where the magnet needed to function. Once the trackers were on, researchers could attract the previously trained birds back to an outdoor ground “feeding station” where the trackers could charge, and the team could download the data.
The team placed trackers on five magpies using their special belt. However, just ten minutes after setting up the last magpie, they noticed something unusual: an adult female without a tracker was busy trying to remove the device from a younger bird, eventually succeeding. This pattern was repeated in the following hour, and by the third day all trackers had been removed.
Researchers are unsure if the same female magpie removed all the devices or if multiple birds cooperated. However, “what we have observed is the first documented case of rescue behaviour in magpies”, according to the paper — something the researchers hadn’t considered going into the project.
But that’s how science works sometimes. The team didn’t get the data they wanted, but their experiment still produced interesting results.

5 . It sounds impossible for a 500-pound bear to break into a house through a small window. But the animal known as Hank the Tank is no ordinary bear: He has used his extraordinary strength to force into at least 28 garages in South Lake Tahoe and is responsible for 152 reports of conflict behavior with the local people over the past seven months.
“This smart bear does not break into a garage where trash is kept,” the police department said in a statement. “He hangs out in the neighborhood quite often because he has been continuously rewarded with food stored in garages.”
The most recent incident occurred late last week, when local police officers were called to a home on Catalina Drive when Hank broke into another garage and the police department has planned a special trapping effort to remove Hank the Tank from the neighborhood. After he’s caught, it will decide whether he can be placed in a controlled habitat or whether he should be killed. “We hope that Hank can avoid the sad ending of another famous bear from the Tahoe area,” it said.
Like Hank the Tank, the 500-pound bear named the Safeway Bear had lost its fear of people. It was known for driving away Kings Beach get-togethers, helping itself to a birthday cake and other treats. In 2020, it was caught on camera stealing food from a grocery store at Lake Tahoe’s northern shore.
The bear was eventually trapped and sent to a remote wild habitat in El Dorado County. Its tracking collar was found in the woods in the spring of 2021, leading biologists to hope that it had successfully gotten used to a natural diet and lost weight, allowing the collar to slip off.
But the truth was very heart-breaking. The big bear was reduced to a shell of its former self and was killed at a campground where a family gathering included small children.
“The action of the shooter was the most humane outcome for this bear,” said one of the biologists.
