阅读理解

    Think of a seed buried in a pot. It's dark down there in the potting soil. There's no light, no sunshine. So how does it know which way is up and which way is down? It does know. Seeds send shoots up toward the sky, and roots the other way. Darkness doesn't confuse them. Somehow, they get it right.

    More surprisingly, if you turn a seedling (秧苗) or a whole bunch of seedlings upside down, as Thomas Andrew Knight of the Royal Society did around 200 years ago, the tips and roots of the plant will sense, “Hey, I'm upside down. Look! I. will turn my way to the right direction and do a U-turn.”

    How do they know? According to botanist Daniel Chamovitz, Thomas Knight about 200 years ago guessed that plants must sense gravity. Knight proved it with a crazy experiment involving a spinning plate.

    He attached a bunch of plant seedlings onto a disc. The plate was then turned by a water wheel powered by a local stream at a speed of 150 revolutions (旋转) per minute for several days.

    If you have been at an amusement park in a spinning teacup, you know that because of centrifugal force (离心力) you get pushed away from the center of the spinning object toward the outside.

    Knight wondered, would the plants respond to the centrifugal pull of gravity and point their roots to the outside of the spinning plate? When he looked, that's what they'd done. Every plant on the disc had responded to the pull of gravity, and pointed its roots to the outside. The roots pointed out, and the shoots pointed in. So Thomas Knight proved that plants can and do sense the pull.

(1)、How does the author write about the young seedling in Paragraph 2?
A、By describing vividly. B、By giving examples. C、By telling stones. D、By asking questions.
(2)、What determines the direction that the plant choose?
A、Soil. B、Sunshine. C、Darkness. D、Gravity.
(3)、What did Knight's experiment prove?
A、Plants have their own desires. B、Plants can feel the pull. C、Speed influences plants' growing. D、Plants can grow quickly by doing a U-turn.
(4)、Where can this passage most probably be found?
A、In a book review. B、In a lifestyle magazine. C、In a scientific report. D、In an official document.

I had the meanest mother in the whole world. While other kidsate candy for breakfast, I had to have cereal, eggs or toast. When others hadcokes and candy for lunch, I had to eat a sandwich. As you can guess, my supperwas different from the other kids' also. But at least, I wasn't alone in mysufferings. My sister and two brothers had the same mean mother as I did.

My mother insisted upon knowing where we were at all times.You'd think we were on a chain gang. She had to know who our friends were andwhere we were going. She insisted if we said we'd be gone an hour, that we begone one hour or less — not one hour and one minute.

We had to wear clean clothes and take a bath everyday. The otherkids always wore their clothes for days. We reached the height of insultsbecause she made our clothes herself, just to save money.

The worst is yet to come. We had to be in bed by nine each nightand up at eight the next morning. We couldn't sleep till noon like our friends.So while they slept — my mother actually had the nerve to break the ChildLabor Law. She made us work. We had to wash dishes, make beds, learn to cookand all sorts of cruel things. I believe she laid awake at night thinking upmean things to do to us.

Through the years, things didn't improve a bit. We could not liein bed, "sick" like our friends did, and miss school. Our marks inschool had to be up to par. Our friends' report cards had beautiful colors onthem, black for passing, red for failing. My mother, being as different as shewas, would settle for nothing less than ugly black marks.

As the years rolled by, first one and then the other of us wasput to shame. We were graduated from high school. With our mother behind us,talking, hitting and demanding respect, none of us was allowed the pleasure ofbeing a drop-out.

My mother was a complete failure as a mother. Out of fourchildren, a couple of us attained some higher education. None of us have everbeen arrested or divorced. Each of my brothers served his time in the serviceof this country. She forced us to grow up into God-fearing, educated, honestadults. Using this as a background, I am now trying to raise my three children.I am filled with pride when my children call me mean. Why? Because now I thankGod every day for giving me the meanest mother in the whole world.

根据短文理解,选择正确答案。

    Over 40 years ago, a country music DJ convention (大会) was held every year in Nashville, Tennessee. Many country performers used to attend (参加) the convention to give their performances. Fans would go to Nashville hoping to see their favorite performers. In the end, so many fans began showing up in Nashville that a festival named Fan Fair was born.

    The first Fan Fair was held in April 1972, in Nashville for four days. Some of country music's biggest stars attended. There were about fifty thousand fans. The first Fan Fair was so successful that planning began almost immediately for 1973. The date was changed to June, when the weather would be better. Over one hundred thousand fans attended the second Fan Fair.

    Every year brought so many performers and fans to Fan Fair that, in 1982, it was moved to the Tennessee State Fairgrounds. Fan Fair stayed at the fairgrounds for another nineteen years.

    There was always the unexpected during the festival. In 1974, former Beatle Paul McCartney attended. In 1992, more than six hundred reporters from Europe, Asia, and South America went to cover the appearance of a popular star, Billy Ray Cyrus, who had introduced a new country line dance. In 1996, Garth Brooks, who made a surprise appearance, signed autographs (签名) for 23 hours.

    In 2001, Fan Fair returned to downtown Nashville as the world's biggest country music festival. Now, over one hundred and twenty-five thousand country music fans go to Nashville every June. As you can imagine, those who want to attend Fan Fair must plan ahead. For example, they need to buy a ticket several months ahead of time. Of course, there's much more to prepare.

    Insects(昆虫) are a very healthy food. They have almost as much protein(蛋白质) as meat from a pig or cow and are low in fat. Eating insects is also very good for the environment since they need less land and water than larger animals.

    Marcel Dicke, who studies insects, explained in a talk how insects also produce more meat from the food they eat. For example, imagine a farmer feeds a cow 10 pounds of food. Those 10 pounds of food produce about 1 pound of meat for people to eat. However, imagine the farmer gives a certain number of insects 10 pounds of food. Those 10 pounds of food produce 9 pounds of meat for people to eat!

    Eating more insects can also help people in poor areas. Many people can raise and sell insects, which can provide jobs and food.

    But insects will not replace animal meat very quickly. First, people in some countries would have to change how they think about eating insects. Many people in North America and Europe eat a lot of meat like beef and pork. But they do not traditionally eat insects. In fact, for many people in the west, eating insects sounds crazy. They believe insects are dirty and dangerous. Insects make them feel uncomfortable.

    Some people are trying to deal with this problem. For example, David George Gordon wrote a book named “The Eat-A-Bug Cookbook”, which tries to show people that insects can be delicious. Other insect experts travel around telling people about the benefits of eating insects. But they will still have a lot work to do.

    There are billions of people on this planet, and many of us love to eat meat. In 2018 alone, the average American will consume more than 100 kgs of red meat, according to a report from the US Department of Agriculture (USDA). At the same time, the environmental impact caused by meat consumption – waste, animal treatment, health issues and even the greenhouse gas effects – has given rise to a number of startups (新兴企业) looking for ways to fill our growing demand for meat. But can the demand be filled in a sustainable and affordable way?

    A bunch of companies are not only optimistic but are working to make this happen sooner. All of these companies harvest cells from animals and grow them in a lab. For example, San Francisco-based Memphis Meats is developing cell-based meats in its laboratories by manufacturing fat and muscle cells without requiring any animals. And don't worry if you're not a meat lover. Startups such as Jet Eat, which is based in Israel, are working on food products grown in labs that are plant based and produce meats using natural ingredients while still maintaining flavor, consistency and the "overall sensory experience".

    As you can imagine, there are plenty of hurdles facing the industry. Educating the public is a big one. Another controversial issue is the labelling of the products. Meat industry trade groups have been pressing the USDA to more strictly regulate alternative meats, labeled as "imitation products".

    Many of us have concerns about the challenges facing future generations as our global population swells and the earth's natural resources shrink. The good news is that there are plenty of companies around the world—like those producing lab-grown meats - who are working to solve some of these problems and make a few bucks in the process. Nothing wrong with that.

    On a rainy winter day, several decades ago, a British artist named Christopher got on a train in Oxford to go to London. When he began his journey, he never knew that it was the beginning of almost 40 years of accidents and near death experiences.

    During the journey, the train fell into an icy river, killing 12 passengers. Christopher managed to swim back to the river bank. He only had a broken leg.

    Two years later, Christopher was on a plane from London to Manchester when a door suddenly opened and he fell out. A few minutes later, the plane crashed; 27 people were killed. Christopher was so lucky that he landed in a haystack (干草堆).

    A few years later, he was hit by a bus, but again had no serious injuries. Then a year after that, he was driving on a mountain road when he saw a truck coming straight at him. He drove the car off the road, jumped out, landed in a tree — and watched his car fall 100 meters down the mountain.

    "There are two ways you can look at it," Christopher said. "I'm either the worlds unluckiest man, or the world's luckiest." When a reporter asked Christopher what he thought, he chose the "luckiest" one.

    Two years ago, aged 71, Christopher bought his first lottery ticket (彩票) in 50 years and won more than 2 million. After this, a TV company in America said they wanted him to make an advertisement. At first he accepted, but then he changed his mind. Christopher said he would not fly to Los Angeles for the filming, because he did not want to push his luck. Who knows? If he had accepted the invitation, maybe he would have had another accident. But Mr. Christopher is a lucky man. If he had had another accident, he probably would have survived that too!
