    In one section, the bridge consists of 【4】 6.7-kilometre undersea tunnel (隧道) and two artificial islands.

    About 400,000 tons of steel was used in the project, equal 【7】 eight times the amount used to build the Sydney Harbour Bridge. According to 【8】(it) engineers, it should be able to withstand a magnitude-8 earthquake, a super typhoon, or a collision with a 300,000-tonne ship.

    【题目】Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

    Most people don’t need science to appreciate the importance of a mother’s love.

    But to understand how early maltreatment can derail a child’s development requires careful study. In a famous research, Harry Harlow had demonstrated that proper psychological and physical development of infants requires nurturing and attention from a parent. 【1】 In that research, socially isolated monkey babies that were removed from their mothers were found to be clinging to a cloth-covered surrogate(替代的) mother for comfort.

    Such experimentations sound cruel. They, however, have been critical in helping change policies in human orphanages( 孤儿院 ) in the U.S. For centuries some orphanages treated infants equally inhumanely. Despite early evidence that orphanage infants were far more likely to die than others, supporters argued that it didn’t matter whether children had “parents” specially devoted to them at the orphanage. 【2】 Orphans were supposed to be in positive mental and physical health until adoptive parents were found. Babies, they said, couldn’t remember anyway.

    The harrowing consequences of these theories were most vividly brought to light in Romania in the 1980s and ‘90s. A ban on abortion（流产 ) led to a surge in orphanage babies. Simply being fed and changed without individualized affection, some babies present serious problems. Many developed violent behaviors, repetitively rocking or banging their heads. Some were cold and withdrawn or indiscriminately affectionate. 【3】 Their head sizes were especially small.

    They even had problems with attention and comprehension. The longer these children were left alone, the more damage was seen.

    The lack of a secure attachment relationship in the early years has destructive consequences for both physical and mental health later in life, with long-lasting effects. The persistence of these effects emphasizes the need to intervene early in life. The Nobel-prize-winning economist James Heckman, has long argued that investing in early childhood education provides a greater return for society than virtually any other type of spending. It is obviously reflected in increased educational success and productivity,. The reduced crime, addiction, distress and disorder point to the same theory. Early life conditions critically affect adult life. 【4】 Remove it and the harm is great.

    A. The appropriate feeding and caring styles were greatly rewarded in all aspects.

    B. It was claimed that simply feeding and changing them would be adequate.

    C. Some, however, demonstrate little influence with roughly ordinary behavior pattern.

    D. Maternal attachment plays a fundamental role in shaping who we are.

    E. Necessities are not just the availability of food and water.

    F. And they simply didn’t grow like normal infants.

    【题目】Directions: After reading the passage below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

    Amid the outbreak of the novel coronavirus pneumonia, almost everyone in China wears a face mask to protect themselves and other people 【1】 the virus. However, many people in the West feel reluctant to wear masks 【2】 there is an increasing number of their compatriots(同胞）being infected.

    According to the Global Times, different attitudes toward 【3】 (wear) masks largely lie in the cultures. In the West, 【4】 people generally believe is that unless one is already ill, wearing a mask is simply unnecessary.

    Siva Kumar from the US is one of them. “Masks can only protect you from particulate matter in the air you breathe, but they can't filter (过滤) out microbes (微生物), "Kumar told China Daily. “wearing a mask when you're healthy 【5】(cause) tension for others."

    US infection prevention specialist Eli Perencevich told Forbes, "The average healthy person 【6】 not wear masks." She added, “If they wear them incorrectly it can increase the risk of infection because they're touching their faces more often."

    However, for people in Asian countries like China, wearing a mask is engrained (根深蒂固的) in their culture. 【7】 (Value) collectivism (集体主义), people in Asia always want to make contributions to the groups 【8】they belong to. In such uncertain and potentially dangerous time, many people have taken the responsibility 【9】(wear) face masks to ensure the safety of their communities.

    Chen Xinjie, a media worker in Beijing said: "Wearing the mask for a long time is stuffy(闷热的) and uncomfortable…But as a member of the group, it's our duty to do so."

    【10】(Influence) by social cultures, the attitudes toward wearing a mask can be different in the East and West. But as US essayist Ralph Waldo Emerson once said, “We must each respect others even as we respect ourselves."

    【题目】Directions : Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

    Environmental pollution kills 1. 7 million children under the age of five every year worldwide. This is according to the World Health Organization (WHO). The WHO warns that child deaths will increase greatly if pollution continues to worsen.

    The most common causes of death among children aged one month to five years are diarrhea, malaria and pneumonia. This is according to the WHO. 【1】 This means providing access to safe water and sanitation, limiting exposure to dangerous chemicals, and improving waste management.

    【2】 The WHO estimates that air pollution is responsible for about 6. 5 million premature, or early, deaths every year. That number includes nearly 600, 000 deaths of children under age five. Most of these deaths take place in developing countries.

    Air pollution is a leveler between rich and poor, according to WHO environment and health chief Maria Neira. 【3】 And one of the most important ways to reduce air pollution is to produce cleaner fuels for cooking and heating. “Almost half of the world population is using dirty fuels for cooking, heating, and lighting at home. And, this is affecting very much mothers who are staying and cooking at home, but the children who are around mothers -- they are exposed as well. ” Early exposure to harmful pollutants can lead to increased risk of chronic respiratory disease, asthma, heart disease, stroke and cancer later in life.

    Cleaning up how the world cooks, heats and lights homes and other buildings is a big- picture goal. The WHO is advising government departments and industries such as construction and the health sector to work together to clean up their environment.

    【4】 The U. S. Environmental Protection Agency has the following suggestions:

    Avoid walking where there is a high volume of vehicle traffic.

    Equip homes with air filters and air conditioning units.

    Limit your time outside if you live in an area that issues warnings about air quality.

    Wear high-grade, rated face masks tightly to the face when air quality is poor.

    Remove your clothes and wash immediately after entering your house if you live or commute in a very polluted area.

    A. However, of all the environmental pollutants, air pollution is being called the most dangerous.

    B. But what can individuals do to limit our family's exposure to air pollution?

    C. Therefore, the WHO stresses that governments around the world need to take the lead on ensuring that children grow up in a clean environment.

    D. The organization also says reducing environmental risks can prevent such deaths.

    E. A polluted environment is a deadly one—particularly for young children.

    F. Everybody, she says, needs to breathe.
