Most people wrongly believe that when people reach old age, their families place them in nursing homes. They {#blank#}1{#/blank#} (leave) in the hands of strangers for the rest of their lives. Their grown children visit them {#blank#}2{#/blank#}(occasion), but more often, they do not have any regular visitors. The truth is that the idea is an unfortunate myth — an {#blank#}3{#/blank#} (imagine) story. In fact, family members provide the most care {#blank#}4{#/blank#} elderly people need. Samuel Prestoon, a sociologist, has studied {#blank#}5{#/blank#} the American family is changing. He has reported that by the time the average American couple reach 40 years of age, they have more parents than children. Moreover, because people today live longer after an illness than before, family members must provide long-term care. More {#blank#}6{#/blank#} (psychology) have found that all caregivers believe that they are the best people for the job. Social workers interviewed caregivers to find out why they took {#blank#}7{#/blank#} the responsibility of caring for {#blank#}8{#/blank#} elderly relative. Many caregivers thought they had obligation {#blank#}9{#/blank#} (help) their relatives, stating that helping others make them feel more useful. Most hoped that by helping someone, they would deserve care when they became old and dependent. Caring for the elderly and {#blank#}10{#/blank#} (take) care of can be a mutually satisfying experience for everyone who might be involved.

    Every school has a library. A library is a very important part of a school as it helps students to gain and acquire knowledge.

    Our school has {#blank#}1{#/blank#} very large library, which has a large {#blank#}2{#/blank#} (collect) of books, including small storybooks, large reference books, journals, magazines and so on. They {#blank#}3{#/blank#} (arrange) in different sections, so that it is easy for us to search{#blank#}4{#/blank#} a particular book. We usually go to the library to borrow reference books for our studies, but we have seen students from{#blank#}5{#/blank#} (low) grades visit the library to borrow small storybooks.

    We have a librarian who keeps a track of all the books that go in and out of the library. Generally, the books can be kept by us for one week. {#blank#}6{#/blank#} the books aren't returned to the library on time, we will be fined.

    There is a separate reading room in the library{#blank#}7{#/blank#} students can go and read whatever {#blank#}8{#/blank#} like. I love spending time {#blank#}9{#/blank#} (read) books there. It is so quiet that we can really enjoy reading{#blank#}10{#/blank#} (peaceful) and learn a lot of great things in the world.

    Everyone {#blank#}1{#/blank#} (complain) about being stuck in traffic. It is quite possible that the future city will have no traffic at all. H.G Wells, in his book The Sleeper Awakes, tells something about the traffic. In the streets of that future London there will be no vehicles. The city {#blank#}2{#/blank#} (provide) with moving roads. One side of the road travels {#blank#}3{#/blank#} one direction; the other side moves {#blank#}4{#/blank#} opposite way. Anyone who wants to go to another part of the city steps on the moving “way” and sits on one of the seats until he arrives. He has none of the troubles {#blank#}5{#/blank#} a private car brings with it: whether there is enough petrol, whether the tyres are all right, where to park it. The moving way is always at his service, always moving {#blank#}6{#/blank#} (silent) along, always ready {#blank#}7{#/blank#} (take) him to his destination. That city of the future has no traffic jams.

    To link up the {#blank#}8{#/blank#} (vary) cities, vehicles driven by atomic power will pass along highways {#blank#}9{#/blank#} (divide) into two main groups of lanes. Each group will consist of several lanes, some for slow traffic, some for fast. Crossroads will not exist on these highways, but will be replaced by bridges and junctions(交叉口). Where these highways enter {#blank#}10{#/blank#} (city), ports and other built-up areas, they will pass through underground tunnels.

    A 14-year-old Chinese boy overcame two of humankind's most dreaded fears—getting stuck in an elevator and getting homework {#blank#}1{#/blank#} (do), in a single night {#blank#}2{#/blank#}(owe) to his calm-witted character.

    Sun Yixiao was on his way up on Tuesday evening after school,  {#blank#}3{#/blank#} the lift suddenly came to a stop. A moment of panic followed before the  {#blank#}4{#/blank#}(teenage) could find a way out.

    Sun said he tried to open the elevator door, {#blank#}5{#/blank#}(press) all the buttons in the hope to get the elevator to work again, but it didn't work.

    Without a cell phone at hand, Sun tried yelling to get attention of people outside, but no one responded as time passed by. He slipped a note through the door  {#blank#}6{#/blank#} the message "people stuck inside, please ask the property management for help," and hoped someone  {#blank#}7{#/blank#}(pick) it up and act on it.

    After exhausting all his options without knowing how long it would take before someone found him, he took out his textbooks and started to do his homework {#blank#}8{#/blank#}(patient).

    Soon after he finished his duties, Sun heard loud {#blank#}9{#/blank#}(voice) outside. A large crowd including his teachers and other parents had come to the rescue, by which time he {#blank#}10{#/blank#}(trap) in the elevator for over five hours.

    Researchers from the University of Michigan have found that astronauts' brains change shape during spaceflight. It is the first study {#blank#}1{#/blank#} (look) into how the brain changes in space. Researchers looked at high-tech MRI(磁共振成像)pictures of the brains of 26 astronauts who spent time in space. Twelve of the {#blank#}2{#/blank#} (astronaut) spent two weeks on the Space Shuttle, and 14 spent six months on the International Space Station. All of them {#blank#}3{#/blank#} (experience) increases and decreases in the size of {#blank#}4{#/blank#} (differ) parts of the brain. The longer an astronaut spent in space ,the {#blank#}5{#/blank#} (big) the size differences were.

    The research produced some {#blank#}6{#/blank#} (interest) findings. One was that on gravity means fluids do not drop in the body, {#blank#}7{#/blank#} there is a shift in the brain's position inside the skull. The brain becomes either smaller or bigger. The findings could help doctors to treat problems that affect the brain's function. They could treat people with problems {#blank#}8{#/blank#} (cause)by long-term bed rest. They could also help those who have a build-up of fluid in the brain, which can lead {#blank#}9{#/blank#} brain damage. We will understand more about {#blank#}10{#/blank#} neurons(神经元)in the brain connect. The findings will also help future trips to Mars.

    The dog, later {#blank#}1{#/blank#} (name) Arthur, came up to a Swedish team while the members were sharing a meal in front of a 20_mile race stage through the rough area in Ecuador. One of the {#blank#}2{#/blank#} (athlete), Mikael Lindnord, took pity on the dog wandering near their table and fed {#blank#}3{#/blank#} meatball to it. And that meatball made them friends for life, as far as Arthur was concerned.

The extreme sport of adventure racing includes biking, hiking, and boating that challenge even the {#blank#}4{#/blank#} (strong) humans. Imagine a dirty stray（迷失的）dog trying {#blank#}5{#/blank#} (keep ) up. But Arthur {#blank#}6{#/blank#} (do) keep up. The dog followed the team as they got up to leave. {#blank#}7{#/blank#} (actual), he never stopped following them—swimming alongside the boat of the team, and taking on muddy(泥泞的)slopes when the team hiked.

    Arthur stayed alongside the team for the rest of the {#blank#}8{#/blank#} (compete),but not without cost to his well—being. The dog needed doctor's attention after the six-day race was finished {#blank#}9{#/blank#} the team helped Arthur as much as they could during the event. Arthur's hard work paid off: Lindnord decided to adopt(收养) the dog {#blank#}10{#/blank#} brought him back to Sweden.
