• 1．    It is believed that human story begins in Africa and ends about 200，000 years later with their seven billion descendants （后代） spread across the Earth，living in peace or at war，their faces lit by campfires and computer screens.
      In between is an exciting tale of survival，movement，isolation，and conquest，most of it occurring before recorded history.Who were those first modern people in Africa？What routes did they take when they left their home continent 60，000 years ago to expand into Europe and Asia？When and how did humans reach the Americas？For decades，the only proof was found in a small number of scattered bones and artifacts that our ancestors left behind on their journeys.In the past 20 years，however，DNA technologies have allowed scientists to find a record of ancient human migrations in the DNA of living people.
      "Every drop of human blood contains a history book written in the language of our genes，" says population geneticist Spencer Wells.The human genetic code，or genome，is 99.9 percent identical throughout the world.But while the bulk of our DNA is the same，what's left is responsible for our individual differences—in eye color or disease risk，for example.On very rare occasions，a small change，called a mutation，can occur，which is then passed down to all of that person's descendants.Generations later，finding that same mutation in two people's DNA indicates that they share the same ancestor.By comparing mutations in many different populations，scientists can trace their ancestral connections.
      These ancient mutations are easiest to track in two places：in DNA that is passed from mother to child （called mitochondrial DNA，or mtDNA for short），and in DNA that travels from father to son （known as the Y chromosome，the part of DNA that determines a child will be a boy）.By comparing the mtDNA and Y chromosomes （染色體） of people from various populations，geneticists can get a rough idea of where and when those groups separated in the great migrations around the planet.
  
  （1）The best title for this reading could be "

  "．
  A．Exploring Human History
  B．Finding DNA Differences
  C．Making a Biology Experiment

  A．A drop of blood contains genetic information that can tell a person's ancestral history.
  B．The organization of information in a history book is similar to the organization of DNA within a gene.
  C．Every drop of blood contains enough DNA information to fill many history books.
  D．Although people speak different languages，all human blood contains the same language.
  （3）The underlined word "bulk" in Paragraph 3 most probably means

  ．
  A．the large size

• 2．Zea Tongeman，a 14-year-old student，who is crazy about the Internet，applied technology to create an application that encourages people to recycle while having fun.

     The "Jazzy Recycling" application is designed to encourage young people to recycle more，which wins the favor of the youth.It turns waste disposal into a game and helps you find places to recycle.Then you scan what you need to recycle，share it，and get rewards such as shopping vouchers （代金券） and games to be unlocked for what you have recycled.
     Tapping into the teen enthusiasm for sharing every little aspect of their daily life on social media like Facebook，Twitter or Instagram，recycling efforts can be shared too as a fun game among friends，which makes more people take part in recycling activities.
     Zea explains why she is addicted to the Internet and how technology has changed her ideas about the future， "I used to think technology was just fixing computers and using smartphones；I have become very tired from just using what is available.I have discovered another side to it and that I can make technology of my own."
     In fact，Zea Tongeman has taken the idea of recycling seriously and hopes all her fellow beings would give it a serious thought.This teen girl from the United Kingdom has made use of computer programming to create her own app that would encourage people to go recycling for a better world.
  
  （1）What is "Little Miss Geek Day" intended to do？

  
  A．To inspire students to go recycling.
  B．To encourage students to create more.

• 3．On Tuesday，India's Prime Minister Narendra Modi launched a series of new high-producing crop varieties，including herbicide-tolerant （耐除草劑的） rice that can be directly planted into the soil，cutting the huge expenses on water and farm workers.
     In India，the world's biggest rice exporter，the traditional method of rice growing requires farmers to grow seeds in nurseries，and then wait for 20 to 30 days before transplanting the small plants by hand into the fields that are ankle-deep in water.
     With the new seed varieties developed by the state-run Indian Agricultural Research Institute，farmers only need to water the field once to moisten （使?jié)駶櫍?the soil before planting the rice.Besides，the traditional method also uses a lot of water to control weeds as herbicides are costly and often do not distinguish between the rice and the unwanted weeds.
     Government scientists said the new rice varieties contained a gene that would allow farmers to spray a common，inexpensive herbicide without worrying about any side effects. "Our focus is very high on new seeds that can be adapted to new conditions，especially in changing climates，" Modi said.
     Water conservation is likely to be the main attraction of the new rice varieties in India，where farmers rely heavily on monsoon （季風(fēng)） rains.The traditional method uses 3，000 to 5，000 liters of water to produce 1 kg rice.The new varieties could cut water use by at least 50% to 60%，farmers and government officials say. "For farmers like us，the main concern was the management of water，and the new varieties take care of that concern，" said Ravindra Kajal，who grows rice on his 9-acre farmland in the northern state of Haryana.India is also the world's biggest rice producer after China.
  
  （1）Which is the benefit of the new rice？

  
  A．It can produce herbicide.
  B．It can be planted in any field.
  C．It needs a lot of water to grow.
  D．It can save money for the farmers.
  （2）Why can farmers apply a common herbicide to the new rice？

  
  A．The new rice contains herbicide itself.
  B．The herbicide is suitable for all rice varieties.
  C．Genes in the new rice can avoid harm from herbicide.
  D．The herbicide can distinguish the rice from the weeds.
  （3）What plays an important role in rice-planting in India？

  
  A．Water.
  B．Temperature.
  C．Wind.
  D．Sunlight.
  （4）What is the best title for the text？

  
  A．India Launches New Herbicides.
  B．India Cuts Expenses on Farming.
  C．India Promotes New Rice Varieties.
  D．Farmers Appeal for New Rice Varieties.
