2 . The design theory behind a pair of tiny robots may one day find its way into environmental monitoring, as well as search and-rescue tasks. Modeled after a water strider (水黾), an insect, the two robots each weigh in at 8 and 55 milligrams, and may mark the smallest, lightest, and fastest fully functional micro-robots in the world, according to Washington State University (WSU).

Developed by a team of WSU researchers, the robots’ tininess largely relies on a material known as a shape memory alloy (合金). Although shape memory alloys change form when heated, they can “remember” their original shapes and return to them after cooling. Because of this, the two micro-robots do not require standard motors, and they use light and small ones instead of bulky moving parts.

Both the robots’ motors are each made up of two shape memory alloys, allowing them to move their fins as fast as 40 times a second while also lifting over 150 times their weight. “They’re very technologically sound. The development of the very lightweight robots opens up new possibilities in micro-robotics,” said Conor Trygstad, a material engineering PhD student and study lead author. “Although the robots are impressive when compared to other robots, the pair still fall behind their biological relatives’,” Trygstad said. They can currently move at a speed of about six millimeters a second; a water strider, by comparison, speeds along at about a meter per second. For now, the robots also require wired (连线的) power sources, thus seriously preventing any real-world applications for the moment.

Going forward, however, the team plans to copy other small insect species while also creating a new water strider robot which can move at a higher speed. Depending on using small batteries could also greatly increase the robots’ areas of use, If the breakthrough designs continue improving, similar micro-robots could one day be employed to monitor hard-to-reachor dangerous environments.

1. What is the inspiration for the two robots?

A．A special monitor.	B．The lightest micro robot.
C．An insect species.	D．A search-and rescue task

2. What does the underlined word “bulky” mean in paragraph 2?

A．Cheap.

B．Huge.

C．Cool

D．Fast.

3. What might Conor Trygstad agree with?

A．Both robots can identify sound.	B．Both robots need wireless power sources.
C．Both robots work better than water striders.	D．Both robots have weaknesses besides strengths.

4. What is the best title for the text?

A．Robots Are Saving Environment	B．Shape Memory Alloys Are The Key
C．Human Beings Learn From Animals	D．Two Micro robots Can Play A Big Part

3 . 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。

A team of     1     (expert) at the Hebrew University of Jerusalem in Israel, working with a colleague from the National University of Mongolia, conducted a study of the 405-km wall in eastern Mongolia. They used     2     variety of ways in order to learn more about     3     (it) history and purpose. In their published paper, the group     4     (describe) the techniques and technology they used to study the wall.

They mapped the wall,     5     stretches (延伸) from the Dornod Province to the Sukhbaatar Province, roughly along the border (国界) between Mongolia and China. They found that it was unclear when the wall was built, estimated to be between the 11th and 13th centuries. The team referred     6     weather records to learn more about what the wall had experienced over the years and satellite imagery to learn more about connections between wall locations and terrain (地形).

The research team found some surprises. The     7     (big) of all surprises was that the wall had large gaps that suggested it was not made to keep out all invaders (侵略者)—it appeared that it was built     8     (quick) to deal with certain invaders. There was also evidence that suggested the wall was built as a means of     9     (control) the movement of people or animals. Though there were many discoveries, the researchers intended     10     (continue) their work, hoping to learn more.

6 . Soap (肥皂) might seem like a reasonable way to avoid mosquito bites (蚊子叮) on the basis that if mosquitoes can’t smell you, they can’t bite you. However, a recent study has found that rather than protecting you, certain soaps might actually make you more attractive to mosquitoes.

In the study, conducted at Virginia Polytechnic Institute and State University, four volunteers were asked to wear a sleeve before and after washing with four different brands of soap. The researchers then watched female mosquitoes as only females feed on blood landing on the fabric sample to show their preference. They found that some people washing with some brands of soap, increased their attractiveness to mosquitoes, while washing with other brands of soap tended to repel (驱除) mosquitoes. The repellent effect of some soap may be due to its coconut scent, as coconut oil is known to act as a natural mosquito repellent. The reason behind this attraction is believed to be related to mosquitoes’ sugar intake. When mosquitoes are not feeding on blood, they add their diet with plant juice or sweet water from flowers, “The fact we are taking those flowery and fruity smells and putting them on our bodies means that now the same object smells like a flower and a person at the same time,” said Clément Vinauger, who led the study. It would be like waking up and smelling the smell of coffee and bread, very attractive.

Interestingly, the effects of the soap varied among people, possibly due to the interaction (相互作用) between the soap and each person’s unique body scent. “It’s remarkable that the same person that is extremely attractive to mosquitoes when he is unwashed, but he becomes even more attractive to mosquitoes with one soap, and then become repellent to mosquitoes with another soap,” said Vinauger. Further research is needed to better understand the interaction between different soap and body scents, as well as to develop more effective mosquito repellents.

1. What has the study found?

A．Soap attracts many mosquitoes.	B．Male mosquitoes feed on blood.
C．Some plants drive away mosquitoes.	D．Not all soap can stop mosquito bites.

2. How did the researchers conduct the study?

7 . Dallas-based Knit Wits is made up of a group of grandmothers with a strong love for knitting (编织) who tum their love for crafting into a purposeful attempt. Meeting regularly, they pour their collective love into every stitch (针法) they make. The group has been working for over ten years, meeting every Friday, to support organizations that help others, locally and around the world. Over the years, they’ve crafted thousands of items insupport of the important things.

Recently the Knit Wits member Mary Ann Stover was inspired to have the group knit hats for infant (婴儿) patients with heart disease at Children’s Health Hospital. The hats, each a unique work of art, designed with holiday themes, reflect the skill of the Knit Wits. More importantly, the special of Knit Wits is its understanding of the emotional effect these small objects can have on the infants experiencing medical treatments.

Bealle, a certified child life specialist at Children’s Health Hospital, explained how the hats are making a difference to the tiny patients and their families. “Caregivers are able to wear the hats on their body to move their smells before placing the hats back on the infants, encouraging connecting and making the infants less stressful,” he said.

Throughout the infants’ admission, many holidays are celebrated. At times, some infants are seriously ill and unable to dress up for holiday photos the families have planned. Thanks to the donations from Knit Wits, the hospital team is able to prove the family with a suitable themed infant hat the family can use for their photos and holiday celebrations.

1. What do we know about the hats from paragraph 2?

10 . 阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

My two-year-old daughter and I often get smiles from strangers as we walk through our town with Clara riding in her backpack, singing and swinging her feet.

I felt extra grateful for my sunny little girl on one walk at the end of April, 2006. Just three days before she woke up from her nap (小睡) with a fever. We spent a tough evening in the emergency room. Any parent or child is frightened by such an experience. So it was a great feeling that Clara was so happy that day.

We were heading home from a local grocery store, which wisely gives out free balloons to children. Clara always looks forward to getting a balloon there. She did an especially nice job — waiting patiently in the long queue at the store. Luckily, her patience was rewarded with a pink balloon. Pink means a lot to her, especially these days, since the medicine she is taking for the high fever is bubble-gum pink.

Clara was so happy that she started singing “Mister Golden Sun” to her balloon. But when we walked under a tree, POP! There went the balloon. Clara immediately burst into tears. “My pink balloon popped!” She has had many balloons before, but is always very careful with them. This was the first time that she had had such an upsetting experience. Heart-broken, she stared at her poor short-life luck, out of control.

A college-aged young man, about 21, with light brown hair, who was walking behind us noticed Clara’s tears. He was clearly preparing for an important date, as he was carrying a bouquet (束) of a dozen pink roses. He quickened his pace and asked Clara what had happened. Unfortunately, Clara was too shy and upset to answer, but I briefly described the situation, deeply touched that a young guy, probably hurrying home to get ready for a date, would stop to comfort a little child.

注意：
1.所续写短文的词数应为 100 左右；
2.续写部分为一段，开头语已为你写好。

Clara was still crying, unable to say a single word.
