黑龙江省大庆实验中学2018-2019学年高二上学期英语开学考试试卷

阅读短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

    Scientists have connected the "fat gene" with the "happy gene". They believed there could be genetic evidence which explains why fat people are often happier than their skinny friends. The breakthrough could be an explanation for why fat characters, such as The Laughing Policeman and Father Christmas are often described as joyful and kind.

    FTO is the major genetic contributor to being fat. But it is also connected with an eight percent reduction in the risk of depression. Researchers at McMaster University in Canada had been studying whether there was a connection between being fat and being depressed. They found the opposite was true.

    They studied 17, 200 DNA from participants in 21 countries. Results showed people with FTO gene—the fat gene—showed less signs of depression. This finding was supported by three additional international studies.

    Professor David Meyre said, "We set out from the belief that being depressed and being fat both deal with brain activity. We thought that fat genes may be related to depression. However, we have discovered a molecule (分子) contributing to depression. It is the first evidence that an FTO fat gene is connected with protection against depression.

    In a recent interview, actress Lisa Riley said she was more than comfortable with her size. She said she is a "big, really happy" girl who is lucky enough to be confident in her own skin, and added, "Many people want to be thinner. Not me. I love being different and it drives me mad that people don't believe I'm happy with what I am."

(1)、According to the passage, FTO is ________.
A、a molecule connected with happiness B、a kind of DNA from participants C、a gene that contributes to depression D、a gene which leads to being fat
(2)、According to what Professor David Meyre said, we can know ________.
A、his former beliefs were right B、fat genes are connected with depression C、there was no evidence for the role of an FTO fat gene in the protection against depression before D、there should be more people involved in the study
(3)、By mentioning the actress Lisa Riley, the author aims to show that ________.
A、Lisa Riley is unhappy with her size B、it's not easy to be an actress C、many people want to be thinner D、fat people are really happier
(4)、The passage is likely to appear in ________.
A、a health magazine B、a lesson plan C、an advertisement D、an amusement program

    You may use banknotes every day. But did you know that there is a lot of science behind the money? {#blank#}1{#/blank#}

    Australia was the first country to use polymer(聚合物)banknotes in 1988. {#blank#}2{#/blank#}

They can stop water from making them wet. They are also cleaner because bacteria don't grow easily on them.

Now, the Australians have improved their banknotes again by creating a new 5-dollar note. The new one has a clear window in the middle in which there are pictures of an Australian bird and a building. {#blank#}3{#/blank#}

    Tilt (倾斜)the note a little and you will see the bird flapping its wings as if trying to fly away. Turn the note from side to side and you will notice the building come to life and spin. While these features are impressive and entertaining, that was not the reason why the Australian Government spent ten years perfecting them. Their primary purpose was to make it impossible to fake a banknote.

    {#blank#}4{#/blank#} The new $ 5 bill now has a raised bump alongside the two long edges, enabling the blind or those with limited vision, to quickly determine its value.

The Australian government will give the new 10-dollar note the same features in a year's time. {#blank#}5{#/blank#}

A. Note makers still have a long way to go.

B. Other notes will have them in the future.

C. The magic of the new features lies in them.

D. They have many advantages over paper notes.

E. The new Australian 5-dollar note is a good example.

F. The new note is also the first touchable Australian banknote.

G. Their material and pattern set them apart from ordinary banknotes.

    Something's happening at the lowest point on our planet.

The Dead Sea, a salt lake bordered by Jordan to the east and Israel and Palestine to the west, is shrinking(缩小) at an alarming rate—--about 3.3 feet per year, according to the environmentalist group EcoPeace Middle East. And human actions are largely to blame.

    “It's not just like one country is punishing the Dead Sea; it's more like the whole area,” said photographer Mortize Kustner, who visited the area in February to work on his series “The Dying Dead Sea”.

    The Dead Sea needs water from the other natural sources surrounding it, such as the Jordan River basin. But around the 1960s, some of the water sources it relied on were diverted(使改道).Israel, for instance, built a pipeline during that time so it could supply water throughout the country.

    Mineral extraction(开采) industries are another main reason the water levels are falling, experts say. The Dead Sea's minerals have been used as medicine and can often be found in cosmetics(化妆品) and other consumer products.

    And then, of course, there's the Middle East's hot, dry climate, which makes it difficult for the lake to replenish itself.

    Last year, Israel and Jordan signed a $900 million deal in an effort to keep the Dead Sea's water levels stable(稳定). It includes building a canal from the Red Sea to the Dead Sea which would be able to not only supply water to Israel and Jordan but also to pump water into the Dead Sea.

    But for now, Kustner shows us that the Dead Sea remains very much a place of interest, with people from all over the world going there to swim in its salty waters.

    The Dead Sea, known as the Salt Sea in the language of Hebrew, is one of the saltiest bodies of water in the world. And because of what has been happening over the years, the salt is only getting saltier.

    A small insect is getting a lot of attention in the United States. The rusty patched bumblebee (大黄蜂) is the first of its species to be declared endangered in the lower 48 states—meaning every state except Alaska and Hawaii. The rusty patched bumblebee is named for a rust-colored line on its back.

    The U. S. Fish and Wildlife Service announced this month it was adding the bee to its endangered species list. The insects are "on the brink of extinction, " according to the service. It said the bees were once found in 28 states. But there now are only small populations remaining in 13 states. The government agency will make a plan to help the dying bees recover. The agency said that such a plan might help other insects,like butterflies.

    U.S. officials think land owners can take small steps to help the rusty patched bumblebee. They say land owners can be friendlier towards bees by using native plants in their gardens. The insects directly fertilize many kinds of fruit and vegetable crops. And they fertilize grain crops used to feed cattle and milk cows. It costs billions of dollars to duplicate the job the bees do for free. Land owners are also being urged to cut back on their use of pesticide products. The officials also suggest that gardeners leave their plants alone at the end of the summer instead of cutting them. That way, the bees will have a place to live over the winter.

    The Fish and Wildlife Service says the rusty patched bumblebee was added to the endangered species list partly because of habitat loss. Other reasons were disease, pesticides and climate change. Officials are worried that other bees will suffer, too. Another species of bees in Hawaii is also endangered.

    In an effort to discourage people from using plastics, scientists have been hard at work inventing alternative packaging products. From water bottles made from seaweed to cutlery(餐具) made from rice and wheat, a number of inventions are set to change the way we eat while we are on the go, or having a relaxing picnic in the park.

    The idea of using seaweed to make eco-friendly water bottles has been around for a few years. Recently, Ari Jonsson took his invention—a water bottle made from red seaweed—to show off at a festival. The bottles will only hold their shape as long as they are filled. As soon as these bottles are empty they will begin to break down, though they would be perfectly safe to eat. Ari Jonsson's bottles are a step closer to a widely used alternative to the current plastic ones.

    The eatable water container is not the only product to add to our image of the future. Narayana Pessapaty has also created eatable spoons. After the success of his spoons, Mr. Pessapaty is ready to expand and introduce forks and chopsticks to his menu. His aim is to largely reduce the amount of plastic waste, which is a huge problem for waste sites all over the world. It is a product that may take up to 500 years to break down, and recycling companies worldwide are struggling to deal with it.

    Aside from the obvious benefits to the environment, this new packaging is also cheap to produce and therefore cheap to buy. Even better is the fact that similar eatable cutlery can be made at home, possibly a science project for children or just fun with friends. Why not experiment and create your own recipes?

    Gabriella's family immigrated to the US from Peru when she was two years old. As a compound bilingual (双语使用者), Gabriella develops two linguistic codes at the same time, with a set of concepts, learning both English and Spanish. Her teenage brother, on the other hand, might be a coordinate bilingual, working with two sets of concepts, learning English in school, Spanish at home. Finally, Gabriella's parents are likely to be subordinate bilinguals who learned a second language by translating it into their mother tongue.

    Regardless of accent and pronunciation, all types of bilingual people can become fully proficient in a language. It seems that the difference may not be apparent. But recently brain imaging technology has given a glimpse into how specific aspects of language learning affect the bilingual brain. It's well known that the brain's left hemisphere (半球) is in charge of logical processes, while the right hemisphere is more active in emotional and social ones. Language involves both types of functions. "Critical Period Theory" says children learn languages more easily because their developing brains let them use both hemispheres in language learning, while in most adults, language relies on one hemisphere, usually the left.

    Before the 1960s, bilingualism was considered a handicap that slowed the children's development by forcing them to spend too much energy distinguishing between languages. But a recent study did show that bilingualism may make you smarter. It does make your brain more complex, healthier, and more actively engaged, and even if you didn't have the good fortune of learning a second language like a child, it's never too late to do yourself a favor and make the linguistic leap from "Hello" to "Hola" "Bonjour" or "nihao" because when it comes to our brains, a little exercise can go a long way.

Kids and science seem to be made for each other!

The basic science is a combination of thought and experiment called the scientific method. It's where you start with an idea, create a way to prove or disprove your idea, and show what you learned based on facts. Learning to follow this process helps you think logically (逻辑地) and carefully. These important thinking skills can be used in many areas of study. To give a child practice with these thinking skills is like giving vitamins (维生素) to a developing mind.

One of the greatest things we can teach our children is to love learning. Learning science is a great way to do so. Children are easy to be interested in science. Because much of science is hands-on, it attracts most children. Nothing makes a child sit up and take notice like the "WOW!" of a great science showing.

Science opens doors to many subjects at school. Building love for science can be helpful in other areas of study. For example, one cannot love science for very long without becoming good at its language-math! So science encourages children to study math. An interest in science is an interest in how things were once understood compared to how they are understood now. Thus studying science lends itself easily to studying history. And after you do an experiment, you need to write a lab report. Therefore, writing becomes an important part of science.

Science is the basic thing for much of our life. The science of farming shows how our food is produced; biomedical science keeps us healthy; even our beds these days are designed according to scientific facts. We almost eat, sleep and breathe with the help of science! When we prepare the next generation (一代) of voters, creators and policy makers, it is important to make sure they are not only comfortable but also good at science.
