    Venom (毒液) from a local scorpion (蝎子) in Cuba is being used by Cuban scientists as an effective weapon to fight cancer. The venom, with stopping pain, anti-inflammatory (炎症) and anti-cancer properties, is the active ingredient in the medicine “Vidatox 30 CH,” which can be used to treat liver, brain, lung and other cancers. The treatment has been successfully used for more than four years in humans after being first tested in biological models. Labiofam, a Cuban laboratory, has breeding (繁殖) centers for both the Red Scorpion and Blue Scorpion. Each month, some 30,000 scorpions in Las Minas town, 270 km east of Havana are made to give the venom. After two years, the scorpions are released back into their natural habitat.

    Denyer Sanchez, a biologist from Labiofam, explained that the conditions are adjusted for reproduction, proved by the high number of breeding female scorpions. He said when the offspring (后代) becomes able to live in the environment, we release them because they do not have the necessary size yet to remove their venom, said Sanchez. Sanchez also said that there is still much to research on the exploitation process of scorpions, such as female death rate or the ability to survive of the released scorpions.

    Cuban research on the scorpion's venom began at the end of 1980s in Guantanamo province, the island's eastern tip, where a group of biologists and doctors became interested in the stories told by the peasants about the venom's benefits. However, the first discovery was made by Cuban biologist Misael Bordier. In 2001, Bordier visited Mexico's National Autonomous University (UNAM) and presented the research progress in a professional journal. Bordier died in 2005, one year before Cuba's Industrial Property Office gave Labiofam the rights to exploit the patent related to the venom.

A、Their bodies are used to make medicines. B、They are bred in the laboratory for research. C、They are raised to give birth to the offspring. D、They are set free into their natural habitat.
(2)、What can we infer from the passage about the research on scorpions?
A、The UN provided fund for the research team. B、There is still much to study in detail. C、The achievements will benefit animals. D、Many scientists doubt about the result of the research.
(3)、What can we learn about Bordier in the last paragraph?
A、He was given the rights to exploit the patent. B、He began his research at the beginning of the twenty-first century. C、He put forward the research progress in a professional journal. D、He was a peasant who told the stories about the venom's benefits.
(4)、What does this passage mainly talk about?
A、The various uses of scorpions in Cuba. B、Cuban biologists' research on strange diseases. C、Suitable conditions for Cuban scorpions to breed. D、Cuban scorpion venom's effect on fighting cancer.

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel pressured to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset (思维模式) helps them embrace learning a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    Mass media are tools of communication.Mass media allow us to record and pass information rapidly to a large,scattered(分散的)audience.They extend our ability to talk to each other by helping us overcome barriers caused by time and space.

    There are various ways in which mass media make daily life easier for us.

    First,they inform and help us keep a watch on our world. They gather and pass on information we would be unlikely or unable to get on our own.

    Second,mass media help us to arrange our time and life.  What we talk about and what we think about are greatly influenced by the media.When people get together,they tend to talk about certain happenings in the newspapers or on TV.Because we are exposed(暴露)to different points of view through different kinds of media every day,we are able to evaluate(评价)all sides of a certain issue.

    Third,the media are used to persuade people. A good example is advertising through the media.Newspapers,magazines and TV are filled with all kinds of colorful,persuasive advertisements.Though many advertising may not say openly that they want you to buy a certain product,they describe their products in such a way that you may want to buy them.

    Fourth,the media also entertain.  All of the media make some efforts to entertain their audience.For instance,even though the newspaper is primarily a medium of information,it also contains entertainment features(特征).Television,motion pictures,fiction books and some radio stations and magazines are devoted mainly to entertainment.It is estimated that in the future,the entertainment function of mass media will become even more important than it is now.

    Holidays are really important. Many of us will have childhood memories of summer holidays where we were taken away from home to experience new environments and learn in different ways.

    But holidays are expensive and, for those on low wages or living on benefits, they are often unobtainable. Even the cheapest holidays require travel and other additional costs that are difficult for many families to meet.

    For working parents, the long summer break can be a very difficult problem for childcare. When an annual leave allowance amounts to only five weeks, there is a need to spread this across the year. Couples can find themselves taking leave in turn in order to care for children who are on holiday. For some ' this makes even an affordable family holiday difficult.

    The schools that I visit in Nottingham are full of experienced staff committed to giving our children a caring and inspiring learning environment. The number of children receiving free school meals is quite large in Nottingham and many schools have breakfast clubs to make sure that children get a healthy start to the day. Most schools undertake programs of group or individual educational support. Schools also have an important role in sofeguaiding children's welfare through the ongoing touch and support with their pupils. During the long summer holidays, much of this is missed.

    While teachers are holidaying in the UK, many of their pupils spend the whole six weeks on the street where they live. The lack of free school meals for six weeks can result in pressure on a family budget and an inability to afford the inspiring experiences that help children to continue their learning.

    In setting out its plans for a five-term year, Nottingham City Council (委员会)is seeking to reduce the summer holiday down lo four and a half weeks, with a more balanced five terms of roughly eight weeks, each followed by a two-week break. We believe this will give real “down time" for school staff and pupils alike but will be short enough not to cause a real break in learning.

    We acknowledge that this change may be difficult for some school staff, particularly whose own children are educated in other authorities. However, this must be weighed against the benefits for city children for whom we all have the greatest duty of care.

    Scientists in Argentina have created the world's first cow with two human genes that will enable it to produce human-like milk.

    Genetic engineering was used to introduce the "mothers' milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.

    As an adult, the cloned cow "will produce milk that is similar to that of humans", which will prove "a development of great importance for the nutrition of infants(婴儿)", said the institute. "The cloned cow, named Rosita ISA, is the first in the world with two human genes that contain the proteins present in human milk," said the statement.

    In April, scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team said the Chinese only introduced one human gene, while their research involved two, meaning the milk will more closely resemble that of humans.

    “Our goal was to raise the nutrition value of cows' milk by adding two human genes, which do good to the immune system of infants,” said Adrian Mutto, from the National University of San Martin which worked with the institute.

    Cristina Kirchner, President of Argentina, said that the scientific institute made all Argentines proud. She also said that she had refused the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more proper to call it Rosita.”
