In a speech this week to the Institute of Civil Engineering, the Prime Minister, David Cameron, made clear his support for wind energy. He focused on some of the many advantages of developing the industry.

Let’s examine those reasons. It is an abundant, clean and sustainable source of energy, reducing our dependence on expensive fossil fuel imports, increasingly from politically unstable parts of the globe. Let’s not forget that Russia turned off the gas supply to Europe in 2006.

More recently, we have all felt the pain this winter, when international gas prices soared by 40% compared to last year. Should we carry on exposing ourselves to the instability（不穩(wěn)定） of global energy prices and the unpredictability of global events, or should we recognize the value of taking control of our energy supply?

As for the economic opportunities, over the last decade wind energy has attracted $5 billion in investment(投資) to the UK and is set to go above $50 billion by 2020. Look at the companies queuing up to build wind turbine (渦輪) factories in the UK, such as Siemens and Vestas. Examine the number of people employed in the wind industry in the UK—nearly 12000, now with nearly 90000 jobs by 2021.

The UK is already the global leader in wind power, with greater ability than anywhere else in the world—enough to supply more than a million homes with electricity all year round—and the government is calling for an increase by eight times in the amount of wind turbines installed by 2020, which the industry can achieve as long as it gets the right level of support from ministers. In return, as well as bring the environmental benefits of clean energy, the wind industry is committed to save consumers a lot of money.

1.What can we know from Paragraph 4?

A. Many job opportunities are created by wind industry.

B. The UK would not accept many companies’ investment.

C. Over the last ten years the UK has attracted little investment.

D. Other industries are less important than wind industry.

2.The writer uses the example of Russia to prove that ________.

A. international gas price is not always stable

B. there exists the unpredictability of global events

C. there are conflicts between Europe and Russia

D. every nation is badly in need of gas

3.What is the most important thing for the government to achieve its goal by 2020?

A. Attracting more investment.

B. Getting enough support from ministers.

C. Improving the technology a lot.

D. Listing the advantages of wind power to the public.

4.What is correct for the UK facing the problem of energy?

A. The UK should increase its dependence on fossil fuel imports.

B. It’s OK to carry on exposing itself to the instable energy prices.

C. The UK should believe the global events can be predictable.

D. The government has recognized the necessity of controlling its energy supply and did better.

Habits Of Highly Successful Students

Never Over-Study

When you spend too much time studying you will quickly lose focus and the time spent in studying will become ‘junk time’.

Instead, take regular breaks.1.Besides, it will give your mind some time to take in what you have been doing.

If you want to be successful, do as successful people do. Set a plan and, set a goal and stick to it, which will create a routine and a routine is the first step towards developing a habit.3.

Front Up To The Toughest Work First

Many of us like to do the easy things first to build our confidence. That’s fair enough.

So what happens then?4.We all do it. We really shouldn't, though. So develop the habit of giving your primary energy to the hard tasks and completing the easy stuff last.

5.

Do we really have to explain this? Just turn them off for an hour, we promise the world will still be there when you log back in! Don't text your friends, don't chat while doing memory activities，don't make phone calls, just focus on what you're doing. Even if you focus on work' for 15 minutes followed by 5 mins of chatting, it’s better than 30 minutes of work while also chatting! You get that right?

Alpacas(羊駝) are members of the camel family, having lived in South America for thousands of years. Their fur gives the animals a teddy bear_like appearance. Alpacas are too small to be used as animals of burden but are valued only for their fur. Generally, their lifespan is around 15 to 20 years.

Alpacas are social animals that live in family groups made up of a male, females and their young. They are gentle, elegant, curious, intelligent and observant. They are safe and pleasant to be around, moving gracefully and slowly around the field, and are therefore unlikely to run into or over anyone, even small children. Occasionally, an alpaca will spit snd kick, but the soft padded(有爪墊的) feet usually do little more than just“get your attention”.

Because these animals are environmentally friendly and need so little grass and food, you can usually raise from two to eight alpacas on an acre of land with grass or hay. A single, 60 pound bale(大捆) of hay can generally feed a group of about 20 alpacas for one day. Alpacas also require access to plenty of fresh water to drink.

Alpaca fur is used for making knittedd and woven(編織) items, just as sheep’s wool is.These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles(針織品) in South America, and sweaters, socks, coats and bedding in other parts of the world. The fur comes in more than 52 natural colors as classified in Peru, 12 as classified in Australia and 16 as classified in the United States.

Life may have evolved on at least three planets within a newly discovered solar system 39 light years from Earth. Astronomers at the NASA have discovered no less than seven roughly Earth-sized worlds orbiting a dwarf star in the system. Scientists had previously identified a tiny number of "exoplanets", which are believed to have the qualities needed to support life. However, the new system contains an unprecedented(前所未有) number of Earth-sized, probably rocky planets, and is being acknowledged as an "accelerated leap forward" in the search for extraterrestrial (外星球的)life.

Three of the new planets are said to be particularly promising because there might exist oceans. Thomas Zurbuchen, associate administrator of NASA, told a press conference in Washington: "This gives us a hint that finding a second Earth is not a matter of 'if', but 'when'."

The planets were discovered using NASA's Spitzer Space Telescope, which was able to track how fast each of the planets crossed the star Trappist-l and completed an orbit. From this the research team calculated how far the planets were from their star, and therefore how likely they are to be habitable.

NASA's Hubble Space Telescope is already being used to search for atmospheres around the planets. Future telescopes, including the proposed European Extremely Large Telescope and the James Webb Space Telescope, may be powerful enough to discover markers of life, such as oxygen in the atmospheres of exoplanets.

Astronomers believe there could be as many as 40 billion potentially habitable worlds in our galaxy, the Milky Way. Prof Zurbuchen said that now was a "gold-rush phase" in the search for these exoplanets.

1.What makes the new discovery significant?

A. Ample markers of life. B. The potential to support life.

C. Great distance from Earth. D. The search for extraterrestrial life.

2.What helps explore atmospheres around the exoplanets?

A. Spitzer Space Telescope. B. Hubble Space Telescope.

C. European Extremely Large Telescope. D. James Webb Space Telescope.

3.What may be the best title for the text?

A. New Solar System Found B. Second Earth Discovered

C. Why to Explore Outer Space D. Gold-Rush Stage to Come
