人教版《Unit 3 Under the sea》2022年單元測試卷（A卷）

第一部分 閱讀理解（共兩節(jié)，滿分37.5分）第一節(jié) （共4小題；每小題2.5分，滿分37.5分）閱讀下列短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。

• 1．Getting less sleep has become a bad habit for most American kids.According to a new survey （調(diào)查） by the National Sleep Foundation，51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights，even though they have to get up early.Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day，and 15% said they had fallen asleep at school.
     How much sleep you need depends a lot on your age.Babies need a lot of rest；most of them sleep about 18 hours a day!Adults need about eight hours.For most school-age children，ten hours is ideal （理想的）.But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours.And guess what almost half of the surveyed kids said they do before bedtime？Watch TV.
     "More children are going to bed with TVs on，and there are more opportunities （機(jī)會） to stay awake，with more homework，the Internet and the phone，" says Dr.Mary Carskadon，a sleep researcher at Brown University Medical School.She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep.Other experts say part of the problem is chemical.Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics，but also make it hard for teenagers to fall asleep before 11 pm.
     Because sleepiness is such a problem for teenagers，some school districts have decided to start high school classes later than they used to.Three years ago，schools in Edina，Minnesota，changed the start time from 7：25 am to 8：30 am.Students，parents and teachers are pleased with the results.

• 2．Many Americans spend more time in cars these days than in the kitchen.But as lives grow busier一and waistlines grow larger —a number of health experts are calling for Americans to reduce their risk of cancer and other diseases by cooking at home more and eating out less.
     "When dining out，people are likely to gravitate towards all the wrong things，" says Rachel Brandeis of the American Dietetic Association. "People take in 50% more fat and sodium when they eat out than when they cook at home.And they often miss out on fruits，vegetables and other vitamin-rich 'powerhouse foods' that may reduce the risk of cancer."
     Nutritionists know it's not easy to break old habits.Many people say they hardly have time to exercise，let alone fix dinner.
     Brandeis says her secret is organization.She cooks six nights a week，even though she and her husband both work.She spends 20 minutes thinking about a week s worth of menus and writing a list.She shops just once a week.Brandeis says she chooses easy cooking methods，too，since she is not quite good at cooking.
     The American Institute for Cancer Research has produced a guide filled with tips like Homemade Health".Melanie Polk，the institute's director of nutrition education，says cooking at home has many advantages.It teaches children about nutrition as well as the importance of sharing housework.
     The 39-year-old homemaker Kirstin Kristinus of Washington，DC，says cooking.at home brings her family together.She also tries to reduce her family，s cancer risk by preparing every meal with many different kinds of food.
     "The only way to know that you are getting all the good things is to expose yourself to a wide variety of food，" says Steven Shiff，a doctor in New Jersey. "If you eat out at a restaurant，it's a lot easier to choose unhealthful things."
     "However，families don't have to give up restaurants，" Shiff says. "It is possible to eat healthfully if you eat outside the home.But it takes probably the same sort of planning that you would have to do to prepare meals at home."
  
  （1）What is worrying health experts？

  
  A．Americans are having a too busy life.
  B．Americans are getting fatter and fatter.
  C．Americans are eating out more and more.
  D．Americans are in greater danger of getting thinner.
  （2）What does the underlined part "gravitate towards" in Paragraph 2 mean？

  
  A．Care about.
  B．Forget about.
  C．Be afraid of.
  D．Be attracted to
  （3）What is Melanie's attitude towards cooking at home？

  
  A．Unclear.
  B．Positive.
  C．Worried.
  D．Doubtful.
  （4）From what Shiff said we can infer that

  .
  A．eating out can be as healthy as eating at home
  B．people should stop going to restaurants
  C．restaurants usually serve unhealthy food
  D．preparing meals at home is more meaningful

• 3．Usually，tornadoes（龍卷風(fēng)） are more common in the spring and summer months.Knowing what to do before and during a tornado can save your life and the life of your loved ones.When you hear that you are in a tornado watch，it means that tornadoes or other kinds of dangerous weather are on the way.You need to be ready to go to a safe shelter if tornadoes do happen or if there is a warning.Listen to local radio or TV programmes for the update so that you have information to make decisions about your safety.
     Tornado warnings mean that a tornado has been seen，or that radar has shown there would be a tornado.When a tornado warning is issued for your town or county，take shelter immediately.Tornado sirens（警報器） warn people who are outdoors.Do not expect to hear sirens if you are indoors.Listen to weather reports and watch TV if you are indoors.Remember to have fresh batteries for your radios and flashlights.
     Plan ahead for tornado watches and warnings.Talk to your family，friends and neighbours so that you know safe places to go to get out of danger.Here are some important tips：
     ? Take shelter in a basement，away from any windows.
     If you are in a house or building with no basement，go to the lowest floor，a small centre room such as a bathroom or closet，under the stairs，or in an inside hallway with no windows.
     ? If you are in a mobile home or trailer，plan ahead and get out!
     It is not safe to be in a mobile home or trailer during a tornado.You need to make plans with family，friends or neighbours to go to a safer，stronger home or another building to take shelter.
  ? It is very risky to be in a car or truck during a tornado.
     Know if there are tornado watches in the area and avoid driving into dangerous situations.Instead，take shelter in a basement or strong building.
     ? Have an emergency kit ready and keep it in your safe area.
     A few ideas for things to have in an emergency kit would be water，a flashlight，food （like crackers，peanut butter，granola bars），a radio that uses batteries，any medications you need，and a first-aid kit.
     If you need any further information about preparing for the tornado season or making an emergency kit，call the Four Corners Health Department at （402）362-2621 or click here to view the website http：//www.yorknewstimes.com.

      Ben was awakened by a gunshot（槍聲）.He looked out toward the frozen lake.Near the trees he saw a shining piece of metal.When it moved，Ben saw that it was a long gun.A minute later a man wearing hunting clothes came out of the woods.
      Suddenly a bird flew upward.The man quickly put the gun to his shoulder and shot.Ben watched the bird，praying it had not been hurt.It flew near the ground and went into some tall bushes.Safe，Ben thought.The hunter didn't move for a moment.Then he began to follow the bird. "No hunting!" Ben shouted， "No hunting on my property!" The man called back， "where can I hunt？"
       Ben had just finished putting on his clothes when he heard another gunshot.He walked toward the lake.Fight was the last thing he wanted，but the man must go.Suddenly he heard a bird's wings beating the dry grass.Ben moved quickly towards the sound.He saw a colored head...the head of a beautiful bird.The bird flapped its wings，one of which was broken completely.
      Ben lifted the bird and held it close against his body.It fought to escape，but soon lay quietly in Ben's arms.Ben decided to take the bird home and fix its broken wing so that it could fly again.He was almost through the woods when he heard the hunter behind him. "You just find that bird？" the hunter asked，stepping closer and said， "Give me that bird!"
      "You get off my hand，" Ben told him.The man's face got red， "Mister，" he said， "I have been hunting here all my life.I grew up here." Ben looked into the hunter's gray eyes，his voice raised， "I do not know who you are and I do not care.I own this place and I am telling you to leave!" "Now look，mister，" the hunter insisted， "be reasonable." He raised his gun.A cold wind blew across Ben's face.He felt a chill（寒冷） go down his spine（脊背）.He could still give the bird to the hunter and return home safe.
