Organic (有机的) farming is a type of agriculture that benefits from the recycling and use of natural
products. Use of dried plants not only saves money, but also ensures the growth of crops. The technique is
characterized by the use of green manure (肥料), biological pestcontrol methods and special farming
techniques to keep soil productivity. Limiting the use of manmade chemicals or completely doing away
with them reduces the risk of diseases. Today, organic farming is a major and preferred industry around the
world. Organically grown food products have a huge market, with farmland covering about 10% of the
total worldfarmland cover.
The_hard_work_of_Sir_Albert_Howard,_the_Father_of_Organic_Farming,_has_paid_off.
Advantages of Organic Farming：
(1)The economics of organic farming are characterized by increasing profits through reduced water
use and reduced soil erosion (侵蚀)．
(2)Organic farming produces the same crops as those produced through traditional farming methods,
but uses half the energy, and holds 40% more topsoil.
(3)Farming the organic way enables farmers to get rid of weeds without the use of any chemicals.
(4)The use of green pesticides (杀虫剂) is environmentally friendly and does no harm to human's
health.
Disadvantages of Organic Farming：
(1)Organic methods of farming produce less, compared to traditional farming techniques.
(2)Organic agriculture does little to fight global climate change. Though organic farming practices are
recognized as giving out less CO but not to a significant degree.

Ecotourism is a combination of ecology (the study of systems of living things) and tourism. It is
1 "responsible travel to natural areas that preserves the environment and improves the welfare of the
local people" by the International Ecotourism Society. Actually, ecotourism can mean travel to far-off
places of great natural beauty, but not always in a（n） 2 way. It's a big business, and the attraction of
money can cause people to think about 3 first. While ecotourism offers benefits to people and
ecosystems, it leaves ecosystems open to negative effects, too.
Costa Rica, once a Spanish colony, and independent since 1821, has an ecotourism industry worth
over one billion dollars yearly, and thousands of jobs have been 4 . Nearly 2l percent of the land is now
protected national parks, 5 thanks to ecotourism. Nevertheless, due to the number of people visiting
the country's natural places, some damage to the ecosystem has occurred.
While 6 can have a negative impact on ecosystems, the same areas might have been 7 by
industries such as farming, logging, or mining if there were no ecotourism industry. Shelters（庇护所）
have been created 8 , keeping the ecosystem protected. And, by visiting beautiful rain forests and
seeing rare animals, visitors get a sense of their 9 , and of gratitude for them. Tour guides can also be
educators who train people to love and care for the environment. Visitors can take these 10 with them
to their home countries.
Unfortunately, while their effect may not be 11 in the off-season, the constant parade of visitors in
the high season can be damaging. At one national park in Costa Rica, wild monkeys now feed on garbage
left by the tourists. 12 , ecotourists tend to seek out places with the rarest animals and plants, 13
the most delicate living things.
It is easy to be critical of the ecotourism industry, but it is important to be 14 as well.
Ecotourism can never be"pure". We can't expect zero negative effects on the ecosystem. It is also 5 to
suppose that humans won't go anywhere accessible to them. If protection efforts are maintained and
increased, those remaining places of undisturbed nature may be stressed, but they won't be destroyed.

How to Avoid an Internet Addiction
While it may seem like everyone surfs the web these days, there is a fine line between casually
checking your social media pages and having a fullblown Internet addiction. If you fear that you may lose
interest in other aspects of your life because you prefer to be on the Internet, you may be on your way to an
Internet addiction. __1__
Admit you are at risk of an addiction.

Set aside limited time for computer use.
Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it
somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed
when you are not using it. __3__ If you have a desktop PC, try not to go near it or put something over it
like a sheet.
Call people instead of sending instant messages or texts.
If you are free on weekends, call friends and ask them to go outside. This will distract you from the
computer. __4__
Use an alarm clock or timer.
Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and
make sure that you get off the computer when the time is up. Alternatively create a shutdown timer on your
desktop. __5__

【语篇解读】 本文是一篇说明文，网瘾会给人们的生活带来很大的影响，作者就如何避免网
瘾提出了建议。
1．答案与解析：D 上文谈到网瘾会导致你对生活的其他方面失去兴趣，下文的几条建议则
是有关如何避免网瘾的，D项起着承上启下的作用。
2．答案与解析：G 本段的主旨是“Admit you are at risk of an addiction”，再结合本段讲述的
“越来越多的人有网瘾，这是一个普遍现象”可知，G项“不要觉得不好意思，找到和你一样有网
瘾的人，互相帮助去战胜网瘾”符合题意。
3．答案与解析：B 根据空前的“Try keeping the lid closed when you are not using it.”可知，作
者建议你不用电脑时，把它合上，故选B项“看不到电脑时，你用它的可能性就小”。
4．答案与解析：F 本段的主题是“Call people instead of sending instant messages or texts.”，上
文的“call friends and ask them to go outside”与F项中的“phone your friends or ask for help in person”
呼应，还有上文的“on weekends”与F项中的“on weekdays”前后呼应。
5．答案与解析：C 本段的主题是“Use an alarm clock or timer”，作者建议使用闹钟或定时器
来限制上网的时间，空前的“shutdown timer”与C项中的“shut down your computer after the set
time”相对应。

Dear Mrs. Louise,
I am writing the letter to tell you that Patrick was hurt at school when playing basketball. He sprained
his right wrist when he was dribbling the basketball yesterday. His sprained wrist and some fingers became
swollen though he was treated with ice immediately. The doctor in our community clinic advised him not to
bend them for the time being and he would recover in three days after some medical treatment. So you
needn’t worry about it too much for we will keep him company and attend to him whenever necessary. I’ll
let him call you after today’s treatment is over.
