Cambridge的模考二整合寫作我找不出三項 - 英檢

先空一頁給尚未模考過的人防雷XDDD




















我之前看了JJ的整合寫作 都很清楚的聽力三項對上閱讀三項
但是今天做了Cambride模考二的整合寫作 出現的問題

看文章的時候
1.文章很短?! 我完整的看兩次時間還沒到 請問考試時的文章長度?
2.看完文章找不出他的三個重點 考試時是應該要聽完聽力才找得到還是看文章就會有?

之後聽力
1.有大概聽到三個缺點(事實上有四個) 但是找不到對應文章中的哪邊三點

下面附上文字檔 請大家幫我看一下重點在哪邊呀


Reading - Tidal Power

閱讀大概在介紹潮汐發電的原理還有好處

Technology is available to exploit the potential energy formed
by tides for the generation of electrical energy. The basic structure
is a barrage or dam built across a river estuary or at the mouth of a
bay. This dam is similar to that used in hydroelectric power plants
built across flowing rivers. At regular intervals along the dam, gates
and turbines are installed. When the tide is rising, the gates are
opened. This allows water to flow into the area behind the barrage,
raising the water level there. When the water has reached its highest
level, the gates are closed. Then the tide drops on the seaward side,
and this trapped water is several meters above the sea level. The
gates are then opened, allowing the water to discharge out. The force
of the flow turns the turbines and generates electricity. It is also
possible to use tidal energy when the water flows in the other
direction - through the gates into the estuary from the sea.
In this way, four periods of energy production are possible
every day, since coastal regions experience two high and two low tides
in just over 24 hours. In order for practical amounts of electricity
to be generated, the difference between high and low tides must be at
least five meters. Tidal power is renewable, non-polluting, and
contributes no greenhouse gases to the atmosphere. This kind of system
can provide a useful energy supplement to other sources in an era of
diminishing fossil fuel reserves.



Listening

聽力主要是找到潮汐發電的壞處

OK, now I want to discuss tidal power since I think it's a good example of an
alternative energy source that we should look at critically. OK, now let's
think about some of the possible drawbacks to the system. For a start, tidal
power can never do more than provide a fraction of our total energy needs
since there just aren't enough good locations.

第一個壞處 潮汐發電產生的電力不夠我們使用 因為好的位子不夠

However, tidal power could still make some contribution at a regional level.
But what about the environmental impact? First of all, the quality of the
water in the estuary area will be changed, and this will have an effect, of
course, on the local wildlife. Both the increase in salinity, when seawater
is mixed with estuary water, and also the amount of mud and sediments churned
up in the water will affect the birds and the fish. These conditions could
stimulate the growth of the red tide organism, which causes paralysis in
shellfish and affects many aquatic creatures. And much of the inter-tidal
habitat could be destroyed, and this would have a devastating effect on birds
and vegetation types adapted to these conditions.

水質變化會影響生態 淡水的鹽度增高 泥土增加 會影響鳥跟魚還有其他水裡的生物

And what about the fish that naturally migrate between river and sea? Their
ability to migrate will be hampered since they won't be able to pass the
barrage. Now, it could be possible to make some kind of provision for them to
move freely between salt and freshwater environments, but this would lead to
expensive design considerations.

那種會在海水跟淡水中遷徙的魚受到影響 因為他們跨不過barrage

Also, there are implications for the people living in the area. For example,
fishing boats are normally moored in the estuary for protection from the
rougher waters, but they'll no longer be able to navigate between estuary and
open sea. In such a case, the economy of the whole area could be affected.

影響了附近居民 漁船沒辦法兩邊跑 影響了經濟

So, all of these things are drawbacks of tidal power and need to be matched
against the benefits of alternative energy production.
