Passage OneA few centuries ago, people looked at the birds and wondered what it would be like to fly like them. There were stories of heroes who glued bird feathers on their arms and flew up into the sky. About 500 years ago, some people dreamed a different dream. Instead of flying up to the sky, they dreamed of falling from the sky!In the 15th century, Italian inventors designed a cone-shaped(锥形) device that was supposed to bring a man down safely from a great height. The operator held on to a handle with a straps strapped to his waist. This was the first known design for a parachute (降落伞).Even the great inventor Leonardo da Vinci sketched a type of parachute. His parachute design was in the shape of pyramid(金字塔). Other inventors also sketched their own designs for a parachute. Unfortunately, these were only designs on paper and no one tested them.A Croatian inventor named Fausto Veranzio looked at Leonardo da Vinci’s parachute design and replaced the pyramid shape with one that looked like a sail from a ship. When Veranzio was 65years old, he fell ill. Thinking he would not live longer, he decided to try out his parachute invention. He built his parachute using wood and cloth. Straping his invention to his waist, he jumped off the tall bell tower in his city. He landed safely! He was supposedly the first man to successfully use a parachute. However, some other people thought this story was not true. If that was the case, then the first person to successfully use a parachute would go to a Frenchman named Louis-Sebastien Lenormand in 1783. Leonardo da Vinci’s parachute was shaped like a ______.

Passage TwoOut of all the students who enroll in a massive open online course(MOOC), only about 5 percent complete the course and receive a certificate accomplishment. This statistic is often cited as evidence that MOOCs are fatally flawed(有缺陷的)and offer little educational value to most students. Yet more than 80 percent of students who fill out a post-course survey say they met their primary objective. How do we look at these two facts?We’re used to focusing on completion rates in higher education, but they’re not the only-or even the most meaningful – indicator of engagement in open online courses. With no cost to enroll, no punishment for dropping out, and little reward for actually earning a certificate, MOOCs are fundamentally different from traditional calssess – and students use them in fundamentally different ways.Data from more than 1.8 million students erolled in 36 MOOCs offered by the University of Pennsylvania show that students treat MOOCs like a buffet (自助餐), sampling the material according to their interests and career goals. Some are curious about the subject matter and just watch one or two video lectures; others use the discussion forums to connect with their intellectual peers around the world. Of all enrolled students, nearly 60 percent watch at least one vedio, complete at least one assignment, or post at least once in a forum.So focusing on the tiny fraction of students who complete a MOCC is misguided.The more important number is the 60 percent engagement rate. Students may not finish a MOOC with a certificate of accomplishment, but the courses nonetheless meet the educational goals of millions.What do we learn about MOOCs from Para.1?

Passage ThreeWhether you are hiking through the magnificent redwoods of Northern California, sleeping under the brilliant stars of the Texas sky or watching the sun rise across the rocky cliffs of Maine, expecting the outdoor world can be inspiring, thrilling, and deeply satisfying. And one of the best ways to enjoy the abundant gifts of the natural world is simple, inexpensive, and available to almost every one. Let’s go camping.When you camp, you create a “home away from home” in the fresh air. You don’t need a lot of fency equipment to enjoy camping. What you need is simply a tent large enough for your family. Practice setting up the tent at home to make sure you are familiar with the process before you go camping.Once you find a good site, it’s time to set up tent. Your first job is to set up your tent. Remove all sticks and rocks from the area. Spread a tarp (防水帆布) over the area where your tent will sit. Set up the tent and be sure to stake it down firmly, even if the weather is mild. Otherwise, strong wind can blow your tent away.Next, you’ll need some firewood for a campfire. If gathering wood is illegal at your campground, you must buy it at the camp store. If gathering dead wood is permitted, go on a firewood-hunting journey and bring in a good supply of wood for your campsite, pile the wood safely away from the campfire ring and where no one will trip over the wood or hurt his or her legs on sharp branches.Being a responsible camper requires that you follow the rules of the campground. Do not burn food or plastic in your campfire. Make sure that you leave your campsite in good condition for the next campers. Just before leaving the site, make a final check to be certain that your campfire is completely out. Pour water on the ashes just to be safe!As is suggested by the aurhor, you should practice setting up your tent ______.
