History books recorded that the first film with sound was The Jazz Singer in 1927. But sound films, or talkies, did not suddenly appear after years of silent screenings. From the earliest public performances in 1896, films were accompanied by music and sound effects. These were produced by a single pianist, a small band, or a full-scale orchestra; large movie theatres could buy sound-effect machines. Research into sound that was reproduced at exactly at the same time as the pictures - called "synchronized sound" – began soon after the very first films were shown. With synchronized sound, characters on the movie screen could sing and speak. As early as 1896, the newly invented gramophone, which played a large disc carrying music and dialogue, was used as a sound system. The biggest disadvantage was that the sound and pictures could become unsynchronized if, for example, the gramophone needle jumped or if the speed of the projector changed. This system was only effective for a single song or dialogue sequence. 

In the "sound-on-film" system, sound was recorded as a series of marks on celluloid which could be read by an optical sensor. These signals would be placed on the film alongside the image, guaranteeing synchronization. Short feature films were produced in this way as early as 1922. This system eventually brought us "talking pictures".

The phrase "these signals"refers to______________. 

The coronavirus is usually transmitted by droplets, such as those produced when coughing and sneezing, and by direct or indirect contact with secretions infected by the virus. The virus may also shed in blood, urine and faeces, and, therefore, there is potential for transmission through contact with a wide range of bodily fluids. Certainly, person-to-person spread has been confirmed in community and healthcare settings across Asia and into Europe. There is also a possibility that asymptomatic carriers may be able to infect people. Public Health England (PHE) has classified the COVID-19 infection as an airborne, high consequence infectious disease (HCID) in the UK. 

The application of infection prevention and control (IPC) principles are already widely used by healthcare professionals within hospital and community settings to both prevent the spread of infections and to control outbreaks when they do occur. The WHO has issued interim guidance regarding infection prevention and control when COVID-19 is suspected. This advice is echoed by guidance issued by Public Health England. 

Public Health England(PHE) suggests the coronavirus may pose complications, such as illness pneumonia or severe acute respiratory infection. They also suggest that patients with long-term conditions or are immunocompromised are at risk of these complications. It is important that as first-line staff, midwives are also familiar with the recommended infection prevention and control principles and measures, and ensure they have the appropriate personal protective equipment (PPE) when caring for a patient with suspected COVID-19.

Which could be the best title for the passage? 

The coronavirus is usually transmitted by droplets, such as those produced when coughing and sneezing, and by direct or indirect contact with secretions infected by the virus. The virus may also shed in blood, urine and faeces, and, therefore, there is potential for transmission through contact with a wide range of bodily fluids. Certainly, person-to-person spread has been confirmed in community and healthcare settings across Asia and into Europe. There is also a possibility that asymptomatic carriers may be able to infect people.

The word “They” in the last paragraph refers to__________. 

Most parents want their sons and daughters to have equal chances of success when they grow up. Today, equality of the sexes is largely mandated by public policy and law. However, old-fashioned ideas and a lot of prejudice are still part of our culture and present challenging questions for parents. 

Gender stereotypes are rigid ideas about how boys and girls should behave. We all know what these stereotypes are: A "feminine" girls should be insecure, accommodating and a little illogical in her thinking. A "masculine" boy should be strong, unemotional, aggressive, and competitive. How are children exposed to these stereotypes? According to the researchers David and Myra Sadker of the American University of Washington, D.C., boys and girls are often treated differently in the classroom. They found out that when boys speak, teachers usually offer constructive comments, when girls speech, teachers tend to focus on the behavior. It's more important how the girls act rather than what they say. 

The emphasis on differences begins at birth and continues throughout childhood. For example, few people would give pink baby's clothes to a boy or a blue blanket to a girl. Later, many of us give girls dolls and miniature kitchenware, while boys receive action figures and construction sets. There's nothing wrong with that. The problem arises when certain activities are deemed appropriate for one sex but not the other. According to Heather J. Nicholson, Ph.D., director of the National Resource Center for Girls, Inc., this kind of practice prevents boys and girls from acquiring important skills for their future lives. 

In a recent survey, fifty-eight percent of eighth-grade girls but only six percent of boys earned money caring for younger children. On the other hand, twenty-seven percent of boys but only three percent of girls earned money doing lawn work". If we are serious about educating a generation to be good workers and parents, we need to eliminate such stereotypes as those mentioned previously. 

Gender stereotypes inevitably are passed to our children. However, by becoming aware of the messages our children receive, we can help them develop ways to overcome these incorrect ideas. To counteract these ideas, parents can look for ways to challenge and support their children, and to encourage confidence in ways that go beyond what society's fixed ideas about differences of sext are.

The word "deemed" in paragraph 3 is closet in meaning to ____

WWF, in full World Wide Fund for Nature, international organization committed to conservation of the environment. In North America, it is called the World Wildlife Fund. 

In 1960, a group of British naturalists - most notably biologist Sir Julian Huxley, artist and conservationist Peter Scott, and ornithologists Guy Montfort and Max Nicholson - led an effort to establish an organization that protected endangered species and their habitats. In 1961 the World Wildlife Fund was founded; the international name was subsequently changed to World Wide Fund for Nature in 1989, although in the United States and Canada it retained the founding name. The organization's distinctive panda logo was created by Scott. In the face of growing environmental threats over the ensuing years, the WWF's activities expanded in scope. Today its mission statement is threefold: to conserve the world's biological diversity, to ensure that the use of renewable natural resources is sustainable, and to promote the reduction of pollution and of wasteful consumption. The organization has long included both conservationists and businesspeople with the intention of combining solid scientific data with well-managed action. It also seeks cooperation between nongovernmental organizations, local governments, and local populations. 

The WWF provides money for conservation initiatives around the world. These include programs focused on individual species, forests, and freshwater and marine issues as well as climate change and responsible international trade. The group has also been involved in efforts to provide a safe and sustainable habitat for the world's peoples, both urban and rural, including clean water, clean air, healthful food, and rewarding recreation areas. Among the WWF's notable achievements is its use of debt-for-nature swaps, in which an organization buys some of a country's foreign debt at a discount, converts the money to local currency, and then uses it to finance conservation efforts.

What does the passage mainly discuss? 

History books recorded that the first film with sound was The Jazz Singer in 1927. But sound films, or talkies, did not suddenly appear after years of silent screenings. From the earliest public performances in 1896, films were accompanied by music and sound effects. These were produced by a single pianist, a small band, or a full-scale orchestra; large movie theatres could buy sound-effect machines. Research into sound that was reproduced at exactly at the same time as the pictures - called "synchronized sound" – began soon after the very first films were shown. With synchronized sound, characters on the movie screen could sing and speak. As early as 1896, the newly invented gramophone, which played a large disc carrying music and dialogue, was used as a sound system. The biggest disadvantage was that the sound and pictures could become unsynchronized if, for example, the gramophone needle jumped or if the speed of the projector changed. This system was only effective for a single song or dialogue sequence. 

In the "sound-on-film" system, sound was recorded as a series of marks on celluloid which could be read by an optical sensor. These signals would be placed on the film alongside the image, guaranteeing synchronization. Short feature films were produced in this way as early as 1922. This system eventually brought us "talking pictures".

The word "sequence" is closest in meaning to"______________".
