Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.
This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and breed.
Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn’t disturb the water as it waits for its meal, and there is barely a ripple(波纹) when it skims(掠过) across the surface at lightning speed to catch its prey.
Grass water spiders deal swiftly with larger insects like damsel flies by pulling their heads under the water and holding them there until they drown.
After a meal, the grass water spider spends up to half an hour grooming(修饰) itself. It wipes its eight eyes, brushes its antennae(触角), and takes special care to clean the hairs on its body.
It is the hairs that trap tiny bubbles(泡沫) of air so that the spider can run down a blade(叶片) of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater.
It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac(囊), which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.
How does the grass water spider kill its prey?
A. in a web B. by drowning C. by poisoning D. with its antennae
the writer describes the special spider as “special” because _______.
A. it walks on water B. it has eight eyes
C. of its hairy appearance D. of the way it produces its young
The passage tells us that the spider ______.
A. feeds grass and thistles to its young.
B. lives on blades of grass under the water
C. lives in the grass on the banks of streams
D. eats a meal once every five weeks
The purpose of the passage is to _______.
A. convince readers that spiders are dangerous
B. indicate that the grass water spider is endangered
C. list all of the spiders that can be found in New Zealand
D. describe the characteristics of the grass water spider

I knew there was no future in any of it and that eventually he would self?destruct if he continued using this drug. However, he had been my best friend since grade school, and I didn't have a lot of other close friends. I didn't want to be a loner, but I also didn't want to end up where I thought Jack was going.
I remember finally deciding sadly that it was just too risky to hang out with him any more. And so during my senior year I had to start over making friends. At first I felt awkward, didn't fit in, and felt dumb being alone. But after a few months I made friends with guys who had similar values and also a lot of fun.
My old friend Jack turned into a druggie (瘾君子), barely graduated, and eventually drowned in a swimming pool while intoxicated (喝醉的). It was sad, but I was grateful I had the courage to stick with the_right_decision and long?term thinking at a key time in my life.
If you're having trouble making good friends, remember that your friends don't always have to be your age. I once spoke to a guy who seemed to have a grandpa who listened to him and was a great friend. This seemed to fill the friendship blank he had in his life. All in all, just be wise when choosing friends, because much of your future relies on who you hang out with.

A．any kid who takes drug will drown eventually
B．a kid's future may depend on who he makes friends with
