It is important to make the good impression (印象) from the very first day. You will face new people. You will be in anew place. It may be difficult to know what to do. Here are five tips to help you make it through the first day in a new job:①First impression can last forever. Make sure you make a good one. Before your first day, find out if your new job has a dress code (rules about what you can wear to work). If so, be sure to follow it. No matter what, always be neat and clean.①Get to work on time. Give yourself an extra 15 minutes to make sure you arrive on time.①Pay attention to introductions. You may introduce yourself to your workmates. They will be important to you. They are the ones who will answer your questions when the boss is not around.①Ask plenty of questions. Make sure that your supervisor has told you what is expected of you. If you are not told your duties, ask for a list. Set daily and weekly goals for yourself.①Never be the first one to leave. Watch what others do at the end of work hours.

Of course, things have changed and life is very different.Trips to the Moon are being made every day. Taking a holiday on the Moon today is as easy as taking a holiday in Europe in 2016. At a number of scenic spots (风景胜地) on the Moon, many hotels have been built. In order that everyone can enjoy the beautiful scenery on the Moon, every room has at least one picture window. Everything imaginable is provided for entertainment of the young and old.What are people eating now? People are still eating food. But many foods now come in pill form, and the food that goes into the pill comes mainly from green plants. Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just using a few computers.People are now largely vegetarians (素食者), and they eat only bread, vegetables, fruit and so on and they don’t eat meat or fish. You see, as the number of people increases, the number of animals decreases. So people have to be vegetarians. We are healthier both in our bodies and in our minds, and we know how to deal with all kinds of illnesses. No one has to be ill any more.41．The passage mainly talks about .A．trips to the Moon in 2060B．developed farming in 2060C．what our lives would be like in 2060D．what people would eat in 2060 42．What is true according to the passage?A．Entertainment is provided only on the Moon.B．Many farms on the Moon have beautiful views.C．It takes the whole day to travel to the Moon.D．It’s easy to take a holiday in Europe at present.43．The food we eat in 2060 .A．is green in the colour B．is the same as todayC．has a lot of pills in it D．is mainly made out of green plants 44．What does the underlined word “decrease” mean in Paragraph 4?A．To become less.B．To become exact.C．To become larger.D．To become unknown.45．We are healthier because of the following EXCEPT that .A．what we eat is green food B．we can treat any illnessC．we are largely vegetarians D．we run the farm by using computersMichael Perham (born on 16th March, 1992 in Hertfordshire, England) is a boy who, at the age of 17, became the youngest person to sail around the world in the 50 feet racing boat, completing his journey on 7th August, 2009. He started the world trip on the 15th of November 2008 from Portsmouth, England.Just six days after Michael Perham set sail from Portsmouth, he started having serious problems with the boat, which he was unable to fix himself on the sea. He had to stop in Portugal. Just one day later, he set sail once again, with the hope of breaking David Dick’s world record for the youngest person to sail around the world.Michael met many challenges (挑战) along the way, including rough seas andknock-downs in the Southern Ocean, terrible loneliness and fighting storms, but the largest difficulty Michael faced was the boat itself. It caused one problem after another. Funnily he celebrated his birthday in March last year among the dolphins in Indian Ocean.Michael Perham has entered the record books after becoming the youngest person to sail around the world. The teenager already holds the record for being the youngest people to sail across the Atlantic, aged just 14.Michael Perham plans to create the Sail Michael Fund to encourage young people to take to the water.

People cannot make natural resources, but can get them from the Earth. Examples of natural resources are air, water, copper, wood, oil, wind energy, hydro-electric energy, iron and coal. Refined (精炼的) oil is not a natural resource because people make it.We often say that we can divide natural resources into two different groups: renewable resources and non-renewable resources.A renewable resource can grow again and come back again after we use it. For example, soil, sunlight, water and wood are renewable resources.A non-renewable resource is a resource that cannot grow or come back, or a resource that will take a very long time to come back. For example, coal is a non-renewable resource. When we use more coal, there will be less coal afterward. One day, there will be no coal to make goods. The non-renewable resource can be used up directly, or we can find a renewable resource to replace it. It is important to save non-renewable resources, because if we use them too quickly, there will be not enough in the future.Most natural resources are limited. This means that they will run out. So, it is our responsibility to save resources for the sustainable development (可持续发展).根据短文内容，回答下列问题。
