    With his unique black mane (鬃毛)and impressive stature(身材), 13-year-old Cecil was a popular tourist attraction at the 3.6 million-square-acre Hwange National Park(万基国家公园) in Zimbabwe (津巴布韦).

    Cecil was head of a pride of lions that includes 12 cubs(幼崽), but the well-known lion was shot and killed in early July by American dentist Walter J. Palmer.  

Cecil's death has already sparked an international outcry (强烈抗议) with many calling for an end to hunting endangered animals and for Palmer to be extradited(引渡) to Zimbabwe to stand trial.

Professor David Macdonald, the head of the Oxford University research program that monitored the daily movements of Cecil and dozens of other lions, is deeply saddened by Cecil's death. Macdonald hopes the death can inspire the public to take an interest in lion conservation.

    Macdonald says many of the lions tracked by the program have been shot  and killed. “The background to this story is that there is a crisis for lions throughout much of Africa.” He says.

    African lion populations have fallen almost 60 percent over the past thirty decades, and as few as 32,000 of them remain in the wild, according to the International Fund for Animal Welfare(国际爱护动物基金会).

“And as troubling as it is, the rarer these hunted animals become, the more hunter s are willing to pay to kill them,” said Jeff Flockedn, the fund's North American regional director.

    In addition to excessive hunting, lions throughout Africa also continue to face threats that include conflicts with local farmers, loss of habitat and risk of traffic and railway collisions(碰撞).

    The law says women should have the chance of doing the same jobs as men and earn the same as them. The reality is very different. Women lose because, 25 years after the Equal Pay Act, many of them still get paid less than men. They lose because they do lower-paid jobs which men just won't consider. And they lose because they are the ones who interrupt a career to have children.  All this is reported in an independent study ordered by the Government's women's unit. The biggest problem isn't equal pay in workplaces such as factories. It is the sort of work women do.

    Make a list of low-paid-jobs, then consider who does them. Try nurses, secretaries, cleaners, clerks, teachers in primary schools, dinner ladies and child-care helpers. Not a lot of men among that group, are there? Yet some of those jobs are really important. Surely no one would deny that about nurses and teachers, for a start. So why do we reward the people who do them so poorly? There can be only one answer—because they are women. This is not going to be put right overnight. But the government, which employs a lot of them, and other bosses have to make a start.

    It is disgraceful (可耻的) that we have gone into the 21st century still treating women like second-class citizens.

Libraries

    Public libraries

    Most towns in Britain have a public library. A library usually has a large selection of books and other resources, which library members can use and borrow for free.

    Britain's First Public Library

    The first public library in Britain opened in Manchester in1852. It's first librarian was a man called Edward Edwards, Edwards attended the library's opening ceremony and two famous writers called Charles Dickens and William Thackeray were there too.

    How to Join a Library

    To join a library, go to your local library and fill in a form. You'll receive a library card which is needed when using library services.

    Mobile Libraries

    Not everyone can get a library. Some people live far away from towns and cities. Other people find it difficult to go out because they have an illness or a disability. Thanks to mobile libraries, these people can still borrow books.

    Unlike most libraries, which store books in buildings, mobile libraries usually keep their books in a mini-bus. The back of the mini-bus has shelves for the books, and it is big enough for borrowers to step inside and look around. A driver takes the mini-bus to a certain place at a certain time, so people know when to expect it. They can then return their books and borrow some more.

    All Aboard the Library!

    A school in London didn't have space for a library inside the building. However, everybody agreed that it was still important to have a school library. So the head of the school, Graham Blake decided to park an old bus on the school car park and changed it into a library. Pupils helped to paint the bus, and after eight months, the new library was ready.

    Forget Cyclists, Pedestrians are Real Danger

    We are having a debate about this topic. Here are some letters from our readers.

    ■ Yes, many cyclists behave dangerously. Many drivers are disrespectful of cyclists. But pedestrians are probably the worse offenders.

    People of all ages happily walk along the pavement with eyes and hands glued to the mobile phone, quite unaware of what is going on around them. They may even do the same thing while crossing a road at a pedestrian crossing or elsewhere. The rest of us have to evade (避让) them or just stand still to wait for the unavoidable collision.

    The real problem is that some pedestrians seem to be, at least for the moment, in worlds of their own that are, to them, much more important than the welfare of others.

—Michael Horan

    ■ I loved the letter from Bob Brooks about cyclists (Viewpoints, May 29). I am afraid they seem to think they own the roads.

    I was walking across Altrincharn Road one morning when a cyclist went round me and on being asked what he was doing he shouted at me.

    The government built a cycle lane on the road but it is hardly used.

    The police do nothing. What a laugh they are!

    The cyclists should all have to be made to use the cycle lanes and wear helmets, fluorescent (发荧光的)jacket and tights at night and in the morning. They should pay some sort of tax and be fined for not wearing them.

—Carol Harvey

    ■ Cyclists jump on and off pavements (which are meant for pedestrians), ride at speed along the pavements, and think they have a special right to go through traffic lights when they are on red.

    I was almost knocked down recently by a cyclist riding on the pavement when there was a cycle lane right next to him.

    Other road users, including horse riders, manage to obey the rules so why not cyclists?

    It's about time they had to be registered and insured, so when they do hit a pedestrian or a vehicle, or cause an accident, at least they can be traced and there might be an opportunity to claim.

    Self-driving cars have been backed by the hope that they will save lives by getting involved in fewer crashes with fewer injuries and deaths than human-driven cars. But so far, most comparisons between human drivers and automated vehicles have been unfair. Crash statistics for human-driven cars arc gathered from all sorts of driving situations and all types of roads. However, most of the data on self-driving cars' safety have been recorded often in good weather and on highways, where the most important tasks are staying in the car's own lane and not getting too close to the vehicle-ahead. Automated cars are good at those tasks, but so are humans.

    It is true that self-driving cars don't get tired, angry, frustrated or drunk .But neither can they yet react to uncertain situations with the same skill or anticipation of an attentive Unban driver. Nor do they possess the foresight to avoid potential dangers. They largely drive from moment to moment, rather than think ahead to possible events literally down the road.

    To a self-driving car, a bus full of people might appear quite similar to an uninhabited field. Indeed, deciding what action to take in an emergency is difficult for humans, but drivers have sacrificed themselves for the greater good of others. An automated system's limited understanding of the world means it will almost never evaluate (评估)a Situation the same way a human would. And machines can't be programmed in advance to handle every imaginable set of events.

    Some people may argue that the promise of simply reducing the number of injuries and deaths is enough to support driverless cars. But experience from aviation(航空)shows that as new automated systems are introduced, there is often an increase in the rate of disasters.

    Therefore, comparisons between humans and automated vehicles have to be performed carefully. To fairly evaluate driverless cars on how well they fulfill their promise of improved safety, it's important to ensure the data being presented actually provide a true comparison. After all, choosing to replace humans with automation has more effects than simply a one-for-one exchange.
