For most students, school is over and summer fun is here. Even kids who are going to summer school don't need to be cooped up indoors during these bright sunny days. Why? Thanks to technology, many kids now have the _ of attending "virtual" summer schools online. These "virtual" classes are not new. Many colleges and universities offer online courses where the students never meet; they correspond with their teachers and classmates on the web. Even some traditional schools add to daily classes with internet-based assignments and feedback. There are a lot of benefits to online schooling, and that's why public schools have started participating in this non-traditional type of education. Instead of students riding the bus, going to class, eating lunch at school, and going home in the early afternoon, they can now log on at any time of day or night and learn. This flexible online option requires just as much work and participation as normal summer school. However, the timing is different. Online summer school is not for all students, just like it isn't for all adults. The student needs to be an excellent reader in order to obtain as much information as possible from the lectures. In addition, students must understand computers and be self motivated in order to complete the class successfully. If the students meet these requirements, then online summer school has many advantages. Written lectures can be read and reread until the student understands them. The students can email each other and the teacher if they need help. Students who participate in online summer school often earn higher grades because the teachers can answer more questions without slowing down the entire class progress. And because of this new technology, summer school students can still go to the beach, travel around the world, and take family vacations! Online summer school is not suitable for _ . A) adults or children who are too old B) students who are poor in reading C) those who don't master good computer technology D) students who can't finish homework on their own

(Question)
Known as the "crazy nest lady", Katie Deline-Ray isn't quite sure how many mini handmade harbors she's knitted for injured baby animals. But she's certain it's a lot. Deline-Ray is founder of Wildlife Rescue Nests. She designs and makes strong, soft nests, which she donates to wildlife rescue groups to use as little recovery nests for sick and injured animals. She also shares her patterns for others to copy. Deline-Ray began making her nests in 2013, while she was recovering from a broken hand, and "spending too much time online."One thing led to another -- as happens on the internet -- and she discovered a woman who was making similar nests for U.S.-based wildlife groups, as an alternative to the hard boxes used to contain the animals these groups care for. "I thought it was such a wonderful idea and went searching to see whether there was anything like it set up for our wildlife rescues in Canada," she says. "To my surprise there wasn't. So I started contacting wildlife rescues and they agreed to try some out." Some modifications were made to already-existing patterns. And then, like a little bird taking its first flight, the nests went out into the world. These days, Deline-Ray sends nests -- always for free -- to 60-some wildlife rescue groups, where injured birds and rabbits nestle inside the soft spaces while they are recovering. Her future plans include making more nests, organizing new volunteer knitters and helping as many wildlife rescuers as possible take care of their animals in this charming way. "I have no formal training with wildlife, just a great love for it." Deline-Ray says. "I love making the nests because I have a great admiration for all the amazing work the wildlife rescues do. I feel like I have a part in giving back to wildlife in a small way." What can we infer from the passage? A) People must receive some training in order to help wildlife. B) Katie Deline-Ray set up Wildlife Rescue Nests based in Canada. C) Deline-Ray was once encouraged by an American woman. D) The nests Deline-Ray made were sold all over the world.

Ques: Deception is something that people do all the time ,and it plays an important role in military strategy. Now some researchers are trying to figure out how to get robots to do it, by looking at the behavior of squirrels and birds. At Georgia Tech, a team led by Ronald Arkin , a professor at the School of interactive Computing, studied the literature on squirrels hiding their acorns .Squirrels will hide their food m a certain place, but when they see other squirrels trying to steal from them, they attempt to fool the thieves by running to a fake location. Ronald Arkin and his Ph. D. student Jaeeun Shim used that as a model for robot behavior. They programmed the robot into tricking a "predator " machine by doing what ei squirrel does: showing the enemy a false location for an important resource. The team also looked at how other animals in this case,a species of bird called Arabian babbler~ drive off predators. A babbler will make an alarm call when they see a predator and other babblers will join the bird and make more calls. They then surround the predator, all the while flapping wings and making noises. The babblers don't ever actually fight the animal they want to drive off; they just make enough noises and flaps around enough so that it seems that attacking a babbler isn't worth it They found that the deception works when the group reaches a certain size--essentially, when enough birds arrive to convince the enemy that it's best to back off . Davis modeled that behavior in software using a military scene and found that it worked even if the group didn't have the firepower to confront the enemy directly. The military is interested in this because a robot that can fool an opponent is a valuable tool. It could lead an enemy down a fake trail or make itself look more dangerous than it actually is. What is the main idea of the passage? A) Animals' behaviors are researched to be applied to the study of military robots. B) Robots, fooling tricks are applied to the study of animals'behaviors. C) Birds and squirrels are the animals that are good at deception. D) Researchers are interested m animals'military-related behaviors.

Ques:Sweetest Day is celebrated on the third Saturday in October as a day to make someone happy. It is an occasion which offers all of us an opportunity to remember not only the sick, the aged, and children who have lost their parents, but also friends, workmates, s and neighbors whose helpfulness and kindness we have enjoyed. Over 60 years ago, when a Cleveland man noticed that some people, such as children who lost their parents and patients who lay in bed, too often felt forgotten and _ , he developed in his mind the idea of showing them that they were remembered. He did this by giving them small gifts. With the help of his friends and neighbors, he gave those people small gifts on a Saturday in October. During the years that followed, other Clevelanders began to take part in the celebration, which came to be called "Sweetest Day". Over time, the Sweetest Day idea of spreading cheer to the poor, the sick and children who had lost their parents was broadened to include everyone, and became an occasion for remembering others with a kind act or a small gift. Soon the idea spread to other cities all over the USA. Sweetest Day is not based on any single group's religious beliefs or on a family relationship. It is a reminder that a thoughtful word or deed enriches life and gives it meaning. Because for many people remembering takes the form of gift giving, Sweetest Day offers us the opportunity to show others that we care, in a positive way. What do most people usually do to show their care to others according to the passage? A) They give money. B) They give gifts. C) They send regards. D) They offer help.
