Ⅰ.阅读理解
A(★)
A robot created at Standford University is diving down to shipwrecks(沉船) in a way that
humans can’t do.Known as OceanOneK，the robot allows its operators to feel like they’re
underwater explorers，too.
OceanOneK resembles(像) a human diver from the front，with arms，hands and eyes that
capture the underwater world in full color.The back of the robot has computers and eight
multidirectional thrusters( 推 进 器 ) that help it carefully explore the sites of fragile
shipwrecks.When an operator at the ocean’s surface uses controls to direct OceanOneK，the
robot’s touch-based feedback system causes the person to feel the water’s resistance.
The idea for OceanOneK came from a desire to study coral reefs in the Red Sea at depths
beyond the normal range for divers.While OceanOneK was designed to reach maximum depths of
656 feet，researchers had a new goal：1 kilometer，hence the new name for OceanOneK.The
researchers changed the robot’s body by using special foam to increase buoyancy(浮力) and fight
the pressure of 1,000 meters more than 100 times what humans experience at sea level.OceanOneK
also got two new types of hands and increased arm and head motion.
During OceanOneK’s deep dive in February，team members discovered the robot couldn’t
rise when they stopped for a thruster check.Flotations on the communications and power line had
collapsed，causing the line to pile on the top of the robot.
OceanOneK’s descent was a success.It dropped off a memorial marker on the seabed that
reads，“A robot’s first touch of the deep seafloor—A vast new world for humans to explore.”
Khatib，a professor，called the experience an “incredible journey”. “This is the first time
that a robot has been capable of going to such a depth，interacting with the environment，and
permitting the human operator to feel that environment，” he said.

A new study found some primates(灵长类) are leaving their tree homes and spending more
time on the ground.Led by Timothy Eppley ，PhD，scientists studied nearly 50 species of
monkeys and lemurs(狐猴) to look at the reason behind these changes.
About 15 years ago，Eppley worked with southern bamboo lemurs，which were known to
spend most of their days in the trees，feeding on bamboo leaves.However，he was surprised to
find these lemurs were spending most time on the ground and had an incredibly diverse diet.He
wondered whether habitat reduction and limited food resource availability were driving them to
move to the ground.This inspired him to begin this study.
He reached out to every researcher he could find who may have significant data on primates
from Madagascar or the Americas，the two places with almost all tree-dwelling primates.
Eppley examined more than 150,000 hours of data observed on 32 monkey species and 15
lemur species at 68 sites.He found that they spent an average of only 2.5% of their time on the
ground each month.But the findings showed some interesting differences.
“As habitats are degraded and the climate worsens，primates that are flexible enough to
adapt because of their diverse diets or live in larger groups may be more likely to shift to life on the
ground，” Eppley says.“However，other species that rely on fruit diets or live in small groups
are less adaptable and are less willing to leave the trees.For these species，we will still need to
enforce fast and effective conservation strategies to ensure their survival.”
Although moving to the ground has some advantages in certain situations，primates can face
problems when they leave the trees.They can become victims of other animals and
diseases.Besides，they will be faced with finding appropriate food resources on the ground，thus
having a broad or flexible diet is important.Primates are important seed spreaders within their forest
habitats.The loss of primates would lead to negative effects on the ecosystem.
5．Why did Timothy Eppley begin his study?
A．To try to make primates more adaptive.
B．To study how monkeys differ from lemurs.
C．To figure out the reason for the loss of bamboo.
D．To find out why primates are turning to the ground.
6．How did Timothy Eppley carry out his research?
A．By doing experiments. B．By observing in the wild.
C．By studying collected data. D．By interviewing the locals.7．Which kind of primates are more likely to come down from trees?
A．Those eating diverse diets. B．Those with a large size.
C．Those feeding mainly on fruits. D．Those living in small groups.
8．What will become a concern according to the study?
A．Animals will become less adaptive.
B．The forest ecosystem will become worse.
C．More natural habitats will be lost.
D．More animal-related diseases will appear.
