各位同学们，为了督促帮助大家持续提升英语能力，培君老师们特意给大家准备了雅思每日一包。每天覆盖听说读写内容，坚持完成两周以上，就能见到自己的英语能力不断上涨哟。

1.听写包 答案：

Producing enough energy to meet our needs has become a serious problem.

Demand is rising rapidly, because of the world's increasing population and expanding industry.
Burning fossil fuels, like gas, coal and oil, seriously damages the environment and they'll eventually run out.
For a number of years now, scientists have been working out how we can derive energy from renewable sources,
such as the sun and wind, without causing pollution.
Today I'll outline marine renewable energy -- also called ocean energy -- which harnesses the movement of the oceans.
Marine renewable energy can be divided into three main categories:
wave energy, tidal energy and ocean thermal energy conversion, and I'll say a few words about each one.
First, wave energy. Numerous devices have been invented to harvest wave energy,
with names such as Wave Dragon, the Penguin and Mighty Whale,
and research is going on to try and come up with a really efficient method.
This form of energy has plenty of potential, as the source is constant, and there's no danger of waves coming to a standstill.
Electricity can be generated using onshore systems, using a reservoir, or offshore systems.
But the problem with ocean waves is that they're erratic, with the wind making them travel in every direction.
This adds to the difficulty of creating efficient technology:
ideally all the waves would travel smoothly and regularly along the same straight line.
Another drawback is that sand and other sediment on the ocean floor might be stopped from flowing normally,
which can lead to environmental problems.
生产足够的能源以满足我们的需求已经变成了一个非常严重的问题。
需求量正在激增，因为整个世界人口急剧增长，工业规模不断扩大。
燃烧化石燃料，比如说天然气、煤炭以及石油对环境造成了极其恶劣的损害，它们最终也会消耗殆尽。
科学家已经花费数年在研究我们该如何从可再生资源中提取能源，
比如说太阳、风力资源，它们不会造成污染。
今天我会简要地说一下海洋可再生资源--它也被称作海洋资源--它利用的是海洋的运动。
海洋可再生能源可以被分为三个主要的种类：
波浪能、潮汐能源以及海洋热转换能源，我会就每一种简略说几句。
首先是波浪能。已经有很多投资去开发能够利用波浪能的仪器，
比如说浪龙、企鹅以及巨头鲸，
研究还在继续，尝试找出一种这种效率很高的方式。
这种能源潜力很大，因为这种资源一直都有，波浪停滞也没有任何的危害。
陆上系统、储备库或者是海上系统都可以产生电力。
但是波浪能的问题就是它不够稳定，风会吹得它们往各个方向移动。
这会增加开发高效能技术的困难性：
理想状态下所有的波浪应该可以沿着相同的直线平缓地、有规律性地移动。
另外一个缺点是可能会导致海岸上的沙子和其他的沉积物不能正常地流动，
这可能会导致环境问题。

2.阅读包答案：

我希望我推荐之后你会喜欢这部电影。请记得吿诉我你对这部电影的看法。

3.写作包答案：

It is said that Hua Mulan lived in the Northern Wei Dynasty.Northerners liked practicing martial arts.At that time,nomadic people from the north often harassed the Northern Wei Dynasty,so the government ordered that every household should dispatch a man to the frontline.As Mulan's father was aged,she decided to join the army in place of her father, starting her army life lasting 12 years later.For thousands of years,because of her bravery and simplicity, Hua Mulan has always been the most rcspectcd woman in China.The Walt Disney Company made the story of Hua Mulan into a movie,which was warmly welcomed all over the world.
