[不定项选择题]共用题干 第三篇

Listening Device Provides Early Landslide(山崩;地滑;塌方)Warning

A device that provides early warning of a landslide by monitoring vibrations(振动)in soil is being tested
by UK researchers.The device could save thousands of lives each year by warning when an area should be
evacuated(疏散,撤走),the scientists say. Such natural disasters are common in countries that experience
sudden , heavy rainfall(降雨,降雨量), and can also be triggered by earthquakes and even water
erosion(腐蚀,侵蚀).
Landslides start when a few particles of soil or rock within a slope start to move,but the early stages can
be hard to spot.Following this initial movement,"slopes can become unstable in a matter of hours or
minutes,"says Nell Dixon at Southborough University,UK. He says a warning system that monitors this
movement"might be enough to evacuate a block of flats or clear a road,and save lives".
The most common way to monitor a slope for signs of an imminent(即将发生的)landslide is to watch
for changes in its shape. Surveyors can do this by measuring aside directly , or sensors(传感器)sunk into
boreholes(钻孔,井眼)or fixed above ground can be used to monitor the shape of a slope. Slopes can,
however,change shape without triggering a landslide,so either method is prone to causing false alarms.Now
Dixon's team has developed a device that listens for the vibrations caused when particles begin moving
within a slope.
The device takes the form of a steel pipe dropped into a borehole in a slope.The borehole is filled in
with gravel(砾,沙砾,砾石)around the pipe to help transmit high-frequency vibrations generated by particles
within the slope.These vibrations pass up the tube and are picked up by a sensor on the surface.Software
analyses the vibration signal to determine whether a landslide niay be imminent.
The device is currently being tested in a 6-metre-tall artificial clay embankment(堤岸)in Newcastle,
UK. Early results suggest it should provide fewer false positives than existing systems.Once it has been
carefully and thoroughly tested,the device could be used to create a complete early-warning system for
dangerous slopes.
"Locations with a significant risk of landslides could definitely benefit from a machine like this,"says
Adam Poulter,an expert at the British Red Cross,"As long as it doesn't cost too much."But,Poulter adds
that an early-warning system may not be enough on its own."You need to have the human communication,"
he says,"Making systems that get warnings to those who need them can be difficult." Which of the following statements is true of landslides?
A.The initial movement is hard to spot.
B.They start with a movement of a few particles of soil or rock.
C.They can be destructive in a matter of hours or minutes.
D.All of the above.

[不定项选择题]共用题干 Step Back in Time
Do you know that we live a lot longer now than the people who were born before us?One hundred years ago the average woman lived to be 45.But now,she can live until at least 80.
One of the main reasons for people living longer is that we know how to look after ourselves better.We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need.We know why we sometimes get ill and what to do to get better again.And we know how important it is to do lots of exercise to keep our hearts beating healthily.
But in order that we don't slip back into bad habits,let's have a look at what life was 100 years ago
Families had between 15 and 20 children,although many babies didn't live long.from lots of diseases , especially rickets (佝偻病)and scurvy(坏血病),which are bot diets.This is because many families were very poor and not able to feed their children well.
Really poor families who lived in crowded cities like London and Manchester often slept standing up,bending over a piece of string,because there was no room for them to lie down.
People didn't have fridges until the 1920s.They kept fresh food cold by storing it on windowsills(窗台板),blocks of ice,or even burying it in the garden.
Some children had to start work at the age of seven or eight to earn money for their pai lived 100 years ago,you might well be selling matchsticks(火柴杆)(a job done by many children)or working with your dad by now. A hundred years ago many kids died at an early age.
A.Right
B.Wrong
C.Not mentioned
