Thanks for your letter. ______________________________________________________________________

Yours sincerely，

Li Hua

I’m sorry to hear that you didn’t do good in your last exam. You are not the only one who seems to try your best but ends up in failure in exams. Quite a number of student feel the same way and they tend to lose their confidence but don’t want to study hard any longer. I’m sure you knew that it’s not wise to do so because you might be left far behind.

I was once in the same situation as you. Failure is the mother of success. In the face of failure, which we need to do is to calm down and reflect our learning methods and make some possible changes or to ask the teachers for advice. Anyway, Rome is not built in a day. Only by stick to studying persistently can we make a progress step by step till success. I truly hope I can be of some helpful to you.

Yours ever,

Compared with people in many other countries, the Australians seem to know more about how to enjoy their lives. In Australia, different people have different ways to enjoy 【小题1】 (they) . They also have their own ideas about how to spend time.

Most 【小题2】 (child) , about 80%, work hard in school because they have to take lots of exams. After school, they don’t want to stay at home reading books any more. 【小题3】 , they put aside their schoolbags and go out to play. In this way, they get 【小题4】 (relax) and have fun.

Some old people get up early in the morning. Then they go to the park to read newspapers. It helps them know 【小题5】 is happening around the world. In the evening, they would prefer 【小题6】 (stay) at home watching TV rather than do anything else.

Young people enjoy 【小题7】 (have) relaxing trips on weekends. They go to mountains for a picnic or go to the forest to camp. They usually start on Friday and spend one 【小题8】 two days outside. Then 【小题9】 Sunday evening, they start their way back home. Nobody 【小题10】 (seem) to be in a hurry, although a busy week is waiting for them again.

   When it comes to exercise，most of us fit into one of the two groups — those who keep a regular exercise habit and those who think about being more active but can’t seem to have a plan to do it consistently. Whatever your attitude to exercise，there’s another form of physical activity that many of us car-loving people can do to get enough movement in general.

Studies have shown that putting away your car and walking, biking or taking public transport to work can have a significant positive influence on your health by improving spirits, reducing body weight and lowering the risk of heart disease.

It’s not surprising that taking a bus or a train regularly leads to a more physically active lifestyle. Just think about what comes with using public transport. Those who travel to work without a car walk to stations, climb stairs, often stand while waiting for their bus or train, and then finally travel on foot or by bicycle to their destination. Such active transport can make up for the inactive time spent in work and school environments.

There’s no doubt that the improving public transport system in the city is influencing the way people work and live. But though the public transport system is improving, it is not within easy reach of everyone who would like to use it.

Bike-sharing programs are also growing in popularity（普及）and helping to bridge a gap in the crowded city public transport system. These programs allow users to easily book, ride and return a borrowed bike. Bike-sharing programs help people who might still need to travel some distance between the end of the bus or the underground line and their final destination. They also offer an opportunity to residents and visitors to travel freely around the city without being trapped in a car.

   Dragging a sleigh loaded with enough presents for the world’s children can be no easy skill. But, since ancient times, the Christmas Eve duty has been performed by a team of beloved reindeer.

Soon, however, Santa Claus may have to start looking around for a stronger type of animal, as newresearch shows the species is becoming increasingly puny. A 16-year survey on the arctic Norwegian islands, Svalbard, found the reindeer there have declined in weight by an alarming 12 percent.

The reduction in average body weight is being blamed on global warming. In the research presented lately at a meeting of the British Ecological Society in Liverpool, scientists have explained how upward temperatures are robbing female reindeer of nutrients during important periods of pregnancy.

Snow in Svalbard typically covers the ground for eight months of a year, which, combined with low temperatures, limits grass growth to June and July. But as summer temperatures increase by around 1. 5℃, grass has become more productive, allowing female reindeer to gain more weight by autumn and therefore to have more babies. However, winters have brought with them greater rainfall which freezes when it settles on the snow. Reindeer can often access the poor food sources beneath the snow by clearing it away with their antlers (鹿角) , but they cannot break through the hard ice. As a result, female reindeer are becoming starved, causing them to lose their babies or give birth to the much lighter young.

Despite the findings, reindeer appear to be suffering less from the effect of climate change than some other arctic species. Last week the scientists warned that a third of the world’s polar bears could disappear in the next 40 years.
