Mr. Johnson lived in the woods with his wife and children. He owned {#blank#}1{#/blank#} farm, which looked almost abandoned. {#blank#}2{#/blank#} (lucky), he also had a cow which produced milk every day. He sold or exchanged some of the milk in the towns nearly for other food and made cheese and butter for the family with what {#blank#}3{#/blank#} (leave). The cow was their only means of support, in fact. One day, the cow was eating grass {#blank#}4{#/blank#} it began to rain heavily. While {#blank#}5{#/blank#} (make) great efforts to run away, she {#blank#}6{#/blank#} (fall) over the hill and died. Then the Johnson tried to make a living {#blank#}7{#/blank#} the cow. In order to support his family, Mr. Johnson began to plant herbs and vegetables. Since the plants took a while to grow, he started cutting down trees {#blank#}8{#/blank#} (sell) the wood. Thinking about his children's clothes, he started growing cotton too. When harvest came around, he was already selling herbs , vegetables and cotton in the market {#blank#}9{#/blank#} people from the town met regularly. Now it occurred to him that his farm had much potential and that the {#blank#}10{#/blank#} (die) of the cow was a bit of luck.

    I was driving home late {#blank#}1{#/blank#} my car lost momentum (动力) and got slower and slower. Nothing I did seemed to make any {#blank#}2{#/blank#} (different). “It can't be fuel,” I thought. The petrol gauge (汽油标量) was showing I had plenty {#blank#}3{#/blank#} (leave). Then my car died completely after I {#blank#}4{#/blank#} (manage) to roll to the side of the road. It was an extremely dark, lonely country road. Neither a single person {#blank#}5{#/blank#} any traffic was in sight at all. I felt like an idiot. I should not have left without charging my cell phone. The battery was dead and I was alone without any way {#blank#}6{#/blank#} (contact) my family. Time dripped slowly like a leaking tap.

    “God, help me!” I begged anxiously. “Is there someone who will be kind enough to stop and help me out?” {#blank#}7{#/blank#}, there was no sign of anyone. I was starting to panic, {#blank#}8{#/blank#} (feel) completely abandoned. Suddenly I saw a faint light {#blank#}9{#/blank#} the distance. I waved my white scarf as hard as possible. It was a huge lorry. The driver stopped and kindly drove me to the nearest hotel, {#blank#}10{#/blank#} I had a rest, and I called my family and explained what had happened. How lucky I was! When he stopped for me, I felt as if I had just found a million dollars.

    Not all memories are sweet. Some people spend all{#blank#}1{#/blank#}lives trying to forget bad experiences. Now American researchers are developing a pill,{#blank#}2{#/blank#}will help people forget bad memories. The pill is planned to be taken immediately after a{#blank#}3{#/blank#}(frighten) experience. They hope it might reduce, or possibly erase, the effect of painful memories.

    However, the new research has caused a lot of argument. Supporters say bad memories may ruin people's lives. They come back{#blank#}4{#/blank#}us when we don't want to have them in a daydream or nightmare(噩梦). They usually come with very painful feelings. The pill can help to reduce many{#blank#}5{#/blank#}(suffer). But those{#blank#}6{#/blank#}are against the research say that changing memories{#blank#}7{#/blank#}(be) very dangerous because memories show who we are.

    {#blank#}8{#/blank#}the drug could first be used in only very serious cases, some people even fear that it would become more commonly used. Don't forget people always have the ability{#blank#}9{#/blank#}(use) science for the wrong purpose. What we should do is help people to have{#blank#}10{#/blank#}(good) control of memories.

Logan Wells, a high school student in Massachusetts, developed an app that makes it easier for people to care for loved ones with dementia(痴呆).

Logan was 15 when his grandmother was diagnosed with dementia. "You can't imagine{#blank#}1{#/blank#} terrible its effect was, not only on my grandmother, but on my parents and other family members," Logan said. "It became really hard to stay on{#blank#}2{#/blank#}same page, because we had to have multiple group chats."

So, he came up{#blank#}3{#/blank#}the idea for CareZare, which enables caregivers to work as a team through a communication website. Logan did the coding{#blank#}4{#/blank#} (entire) by himself while his father assisted him in creating the original design and undertook the marketing.

The free app allows users{#blank#}5{#/blank#} (create) a profile(档案)centered around the individual with dementia and invite other people to join and receive{#blank#}6{#/blank#} (message). With the app, you can schedule events, confirm completed tasks, and even add a "heads up" such as the current mood of the patient or poor weather conditions.

       The app is currently being used by over 600 families and they enjoy{#blank#}7{#/blank#} (share) their opinions about it.{#blank#}8{#/blank#}(please) with that, Logan is hoping it will grow.

       "So far our users{#blank#}9{#/blank#}(be) great about giving us feedback so we can tailor(定做)the app to their needs," he said. "Caregiving is such an important issue for them because it's sovl {#blank#}10{#/blank#}(person) for them, just as it is for me."

Yoho National Park is a Canadian national park. {#blank#}1{#/blank#} (cover) an area of about 507 square miles, it was established in 1886.

Because of its special {#blank#}3{#/blank#} (locate), Yoho National Park has many mountains, including Mount Stephen, Mount Balfour, Mount Goodsir and so on. The {#blank#}4{#/blank#} (tall) mountain among them is Mount Stephen. There are also waterfalls in the park. Wapta Falls is the largest waterfall.
