监测技术
Figuring out biodiversity patterns and
detecting rare or just-good-at-hiding species has
long posed challenges for ecosystem monitoring
and conservation efforts.Traditional survey
methods are labor intensive and cover limited
areas.Now,emerging environmental DNA (eDNA)
techniques open new possibilities.
Scientists collect water or soil samples from
an environment and extract(提取)any DNA
traces left behind by organisms.This is the
environmental DNA (eDNA).They then use
one of the two analysis methods-quantitative
PCR gPCR)or DNA sequencing (DNA
)Similar to COVID tests,qPCR is used to
detect if a specific species'DNA is in the
sample.For example,researchers tested river
water eDNA to see if endangered fish X was
present.When it was detected,they confirmed
that the fish lived in that river without directly
seeing it.DNA sequencing analyzes all DNA in
the sample at once.Scientists can then match
the DNA barcodes to databases to identify which
species were in the sampled environment.
Although eDNA sampling cannot identify
new species or those only known from photos and
videos if they are not already listed in the
reference databases,the real power of it lies in
its ability to capture a wide range of organisms.
With just one sample,scientists can detect all
kinds of living things,from bacteria to whales,
in almost any environment where life exists,
including the deep sea and underground caves.
One of the most significant advantages of eDNA
sampling is that it allows scientists to detect
species that are difficult to see or capture.This
is particularly useful when studying rare or very
small species,or when working in environments

like dark water where visibility is limited.
This is just the start.Imagine a future
where eDNA data could be collected from the
most remote oceans by autonomous vehicles,
analyzed by the drone or on board a research
vessel(轮船),and integrated with other
monitoring data so marine managers and the public
can see near-real-time data about the condition
of the ocean.Science fiction?Not any more.
1.What's the author's purpose of mentioning the
example in paragraph 2?

微习惯
Micro habits are simple practices that you
can usually do in a few minutes.1 Making
positive micro habits and keeping them regularly
can be an effective way to improve your life.
Here are some great examples of micro habits
you can start today.
Read an inspiring story
2 Look up stories of people helping
people or stories of hope and write down what
lessons you can learn from them.Many stories
can be read in a matter of minutes,making this
a great micro habit.
Set a productivity timer
Having difficulty concentrating at work?
Setting a productivity timer will help you focus
on the task at hand.You can set that timer for
whatever amount of time you have-fifteen
minutes,thirty minutes,sixty minutes-and
develop the habit of working consistently during
that period.3 Let these minutes be your
time to be positive and productive.
Set a break timer
Much like the previous micro habit,set a
break timer for yourself in between your periods
of productivity.Set that timer and commit to
giving yourself a break.4 If your job has
you on your feet,take a rest by sitting in a quiet
space.If you sit at a desk,get up and walk
around.

can we do to bring happiness to others?Take two
minutes out of your day to text a friend and tell
them how much you care about them.List out
how they have had a positive effect on your life.
You'll be surprised how much this micro habit
will bring a smile to their face,and your
own.5
A.Just remember,it's not a race.
B.That's why micro habits are so great.
C.Use that time to step away from your
work.
D.But that doesn't mean they are less
impactful.
