6 . Billions of insects are moving together over the sky like a black cloud. It’s a swarm of locusts. Many insects move in huge swarms. They form swarms for different reasons. Some move together to look for food or to find new homes. Sometimes insects swarm for protection. These enormous swarms can destroy food crops and harm other living things.

When something disturbs a red fire ants’ nest, out they will come. Not just one or two, but thousands of them. The fire ants swarm all over their victim. Their stings burn like fire. Each ant in the swarm can sting over and over again. The fire ants hold onto their victim with their mouth parts. Then they inject their prey with poison. Most small animals cannot survive the stings from a swarm of fire ants.

When army ants are on the move, anything in their path is prey. Even snakes can’t escape a swarm of these stinging ants. Army ants move together to look for food. They can’t see their prey, but they use smells and sounds to find their way. If they come to a river, they make a bridge with their bodies. They cling together with their legs. Then the rest of the ants can cross the bridge. There is not much that can stop these fierce and cruel ants from chasing their prey.

Insects are not the only animals that swarm. There are many others that do. Most are not harmful to people. Being close to a huge swarm of animals can be scary and dangerous. Some scientists have studied animal swarms. They have found that many swarms follow simple rules. They work together to solve problems. When they work together they are a very strong team.

7 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Have you ever wondered how people type Chinese characters? The answer lies in the wonderfully useful phonetic system     1     (call) pinyin. It's the most commonly used system for spelling out the Chinese sounds, and it uses the letters in the Latin alphabet that you are already familiar       2     .

Pinyin is     3     extremely useful tool and should be the foundation of your Chinese learning. Besides, it's not just for Chinese learners like yourself.     4     (actual), all native Chinese speakers know pinyin,     5     is the first thing Chinese children learn at school before learning characters. So even if you don't know Chinese characters, you can type in pinyin and make     6     (you)understood.

Every single sound that exists in Chinese can     7     (display) easily in a pinyin chart. Once you master these 409 sounds along with the tones, you'll have practically mastered the pronunciation of every single word in the Chinese language. We've also created a series of video     8     (lesson)with practice tools that enable you to record yourself and listen back to it to     9     (sure) that your pronunciation matches the examples. Combined with our Tone Pairs practice tool, you now have everything you need     10     (master)pinyin, tones, and Chinese pronunciation.

9 . Over the decades, computers have affected our lives to an astonishing degree. When the first modern computer was conceptualized and built in the 20th century, it was so large that it took up a whole room. Over time, the technology shrank. First, computers became small enough to sit on a desk and be brought into the home. Then, they were made lightweight and portable, giving us the laptop. Today, most people have something even smaller: a smartphone that can fit into a pocket.

Though that's as compact as most people are used to, computers and technology are getting even tinier! One of the tiniest forms of technology available today is the microbot. A microbot is a very tiny robot -a machine programmable by a computer—that is built to perform specific tasks. You might tend to refer to this as just a small robot, but the size and dimensions of microbots are actually quite precise. A microbot is less than one millimeter in width, approximately the size of the tip of a pencil. In comparison, a small robot, which can be up to 100 centimeters in width, would be absolutely large. If you think that microbots are as small as you can get, think again. Nanobots smaller than one micrometer exist, but these are so small that they aren't visible to the naked eye(肉眼).

Since microbots are so small, they are potentially very cheap. Scientists and engineers working to develop these microbots believe that they could be used to explore environments or areas that are too small or dangerous for people.

Because the computing power of one single microbot isn't that large, microbots could be moved and used in large groups. At the moment, the biggest barrier to the development of these tiny machines is figuring out how to power a robot that can only contain an extremely small battery.

1. What does the underlined word “shrank” in Paragraph I probably mean?

A．got more Automatic.	B．became smaller.
C．got wiser.	D．became larger.

2. What can we know about microbots?

A．They can be used to do risky tasks.	B．They are relatively expensive.
C．They can't be seen by the human eyes.	D．They aren't as precise as expected.

3. What is the key to the future development of the tiny robots?

A．Its function.	B．Its material.
C．Its battery power.	D．Its maintenance cost.

4. Which is the most suitable title for the text?

A．How Small the Technology Can Get	B．How Robots Change Our Future Lives
C．Why Human Beings Prefer Tiny Technology	D．Why Microbots Are Widely Used Worldwide

10 . The road trip is an iconic (标志性的) American family vacation experience. Here are some road trips you can enjoy.

College Tours

If you are mapping out a college tour road trip with your teen, pick a region like the Boston area. There you can visit a mix of options that are large and small, public and private, and a mix of easy-to-get-into and reach-for-the-stars schools. Make the most of your visits by researching hotel stays that give you a taste of campus culture.

Road to Hana

To do this trip right you'll need 10 to 12 hours. The Hana Highway runs along a winding road dotted with 59 (mostly one-way) bridges and there are often a lot of crowds. But patience is rewarded with a large number of Mother Nature's finest offerings. Remember to stop at the roadside stands selling fresh fruit and banana bread.

This stretch of Highway I running up and down the California coastline is an incredibly popular road trip for its breathtaking scenery —just the thing to relax your tired selves while your little ones sleep lightly in the back seat.
