Four Fascinating National Parks in the World
Fiordland National Park
Fiordland National Park on New Zealand’s Southern Island was established in 1952 and is
part of the larger Te Wahipounamu wilderness,a UNESCO World Heritage Area.Covering 1.2
million hectares,Fiordland National Park is home to green rain forests,crystal clear lakes and
snow-capped mountains.Even on the frequent rainy days,the scenery is spectacular,with entire
valley walls turning into thundering waterfalls.Highlight is the amazing Milford Sound with Mitre
Peak,rising 1,692 metres above sea level and one of the most photographed peaks in the country.
Yosemite National Park
First protected in 1864 and one of the first parks in the National Park Service,California’s
Yosemite is a UNESCO World Heritage Site.The park’s central feature is Yosemite Valley,
which is surrounded by hills,trees and spectacular waterfalls.But the Park is so much more than
just a great valley with waterfalls:within Yosemite’s vast wilderness area,you find deep
valleys,grand grassland and more than 800 miles of spectacular hikes.
Serengeti National Park
Tanzania’s oldest and most popular National Park is a UNESCO World Heritage Site and
was recently proclaimed a 7th worldwide wonder.The Serengeti is famous for its annual Great
Migration,a 1,200-mile odyssey of 1.5 million wildebeest and 200,000 zebras,all of them
chasing the rains in a race for life.Your chances of watching a kill are pretty high when you visit the
area in the right season.
Namib-Naukluft National Park
One of the most thinly populated countries in the world,Namibia is not the right place to get
lost.But it is a top destination for those who enjoy unmatched natural scenery and wildlife
viewing.Nowhere is this more evident than in the Namib-Naukluft National Park,the largest game
park in Africa,including part of the Namib Desert and the Naukluft mountain range.

In his new book The Journeys of Trees,science writer Zach St.George explores an
extremely slow migration (迁徙),as forests move inch by inch to more hospitable places.As old
trees die and new ones grow up,the forest is—ever so slightly—moving,he writes.“Through
the fossils(化石) that ancient forests left behind,scientists can track their movement.They move
back and forth across continents,like migrating birds or whales.”
This has happened over thousands of years,and climate change tends to be the driving force
—pushing and pulling forests around the globe.Of course,today,climate change is speeding
up,and trees can’t keep pace.Take California:It’s getting hotter and drier and scientists
estimate that before too long,Joshua Tree National Park may not be able to sustain Joshua
trees.Zach St.George describes a similar threat to Sequoia National Park,during California’s
long and severe drought a few years back.
Scientists worried that maybe Sequoia National Park would no longer be the place for giant
sequoias.St.George thinks at some point we will lose these ancient trees and we will have to think
about what we do with the places,and do we plant new ones somewhere else? This is known as
“assisted migration”—humans planting trees in other places where they’re more likely to grow
well.But this process carries risks—people can accidentally introduce insects and diseases to new
places,where they may wipe out entire native populations.So,St.George writes,there’s a
debate among conservationists and foresters today:Should humans help the trees escape?
“I think there are going to be instances where people are probably going to step in and help
species move to places where they’ll be more suitable in the future,” St.George says.“And I
met a lot of people in the process who have felt sorry about what has been lost and what will be lost
—and are still continuing to try and do good and work in the moment for small things.”
4.What does the underlined word “They” in paragraph 1 refer to?
A.Animals. B.Fossils. C.Scientists. D.Forests.
5.Why is Sequoia National Park mentioned?
A.To confirm the problem of the loss of tree species is serious.
B.To argue humans should be responsible for the loss of trees.
C.To explain climate change results in the migration of forests.
D.To prove forests can slow down the process of climate change.
6.What can be inferred about assisted migration?
A.It can prevent the trees escaping. B.It can promote biological diversity.
C.It may help to protect the forests. D.It may affect species in new places.7.What is St.George’s attitude to assisted migration?
A.Supportive. B.Doubtful. C.Ambiguous. D.Intolerant.

A Purdue University invention could save millions of taxpayer dollars and significantly reduce
traffic delays.The new invention , a sensor that allows concrete to “talk” , decreases
construction time and how often concrete pavement (路面) needs repairs while also improving the
road’s sustainability and cutting its carbon footprint.Fixed directly into a concrete pour,the
sensor sends engineers more precise and consistent data about the concrete’s strength and need
for repairs than is possible with currently used tools and methods.
“Traffic jams caused by repairs have wasted 4 billion hours and 3 billion gallons of gas,on
a yearly basis.This is mainly due to insufficient knowledge and understanding of concrete’s
strength levels,” said Luna Lu,who has been leading development of the sensor since
2017.“For instance,we don’t know when concrete will reach the right strength needed to
accommodate traffic loads just after construction.The concrete may be put into use too early,
leading to frequent repairing,” she added.
With the technology Lu and her team invented,engineers can directly monitor the fresh
concrete and accurately measure many of its properties at once.The sensor notifies engineers via a
smartphone app exactly when the pavement is strong enough to handle heavy traffic.The stronger
the pavement is before being used by vehicles,the less often it will need to be repaired.By
decreasing road repairs and construction timelines,this technology could reduce carbon dioxide
that vehicles would have given off while waiting in traffic to get around a construction site.
Methods that the industry has used for more than a century call for testing large samples of
concrete at a lab or onsite facility.Even though these tests are well understood by the industry,
differences between lab and outdoor conditions can lead to inaccurate estimates of the concrete’s
strength due to the different concrete compositions and temperatures of the surrounding area.
8.What can be learned about the new invention?
A.It decreases accidents. B.It is costly to produce.
C.It reduces road repairs. D.It is difficult to operate.
9.What does paragraph 2 mainly talk about?
A.Waste caused by road repairs. B.Characteristics of the concrete.
C.Situations of road constructions. D.Necessity of inventing the sensor.
10.What does the underlined word “notifies” in paragraph 3 mean?
A.Signals. B.Awakes. C.Monitor. D.Examines.
11.What is the problem with the previous tests?
A.Samples must be tested on the spot.
B.The results turn out to be unreliable.
C.Fewer properties have been measured.D.Concrete is tested in certain temperature.
Ⅱ.七选五
Have you always dreamed of having a garden,but thought you didn’t have enough space?
1 With a little planning and creativity,you can still make a beautiful garden from the small
outdoor space.Here are a few tips that you can follow.
Plan your layout(布局) carefully. 2 Consider the overall arrangement of the space and
create different zones for different purposes.By dividing the space into smaller sections,you can
put in them different plants you want to grow.You may want to make an outline or use a design tool
to visualize your ideas.Or it’s a good choice to search online for digital garden planners to help
you design the layout.
3 If you have limited space,it’s important to select plants that will grow well in your
garden.Look for plants that are suited to the climate,soil type,and growing conditions.Or choose
dense or small sizes of plants to maximize your space.For professional advice,you’d better talk
to an employee at a gardening center,who knows better.
Make use of vertical (垂直的) space.One of the best ways to make the most of your small
garden is to use vertical gardening techniques.Vertical gardening is an excellent way to add more
greenery to your small garden without taking up too much space. 4 You can also use hanging
baskets to add more greenery to your space.
Include the eatable into your garden.Growing your own food is not only satisfying,but it can
also save you money on groceries.Even if you only have a small garden,you can still consider
growing a variety of fruits,vegetables,or herbs,which can be grown in containers or planting
beds. 5
With these tips in mind,you can create a beautiful and productive garden in even the smallest
of spaces.Happy gardening!
A.It’s time to think again.
B.Follow design principles.
C.Choose appropriate plants.
D.First of all,owning a garden matters.
E.You can grow plants on walls or ladders.
F.Before planting,think about how to use your garden.
G.They can provide fresh and delicious produce throughout the season.
