高考英语二轮复习备考：七选五阅读专题训练

Task 1

Australia's native and unique wildlife—koalas are under constant threat from human

activity and natural disasters. 1 Therefore， protecting the unique species is

important.

So， what is so special about koalas and what makes them so “cool”？ 2 Or

could it be their laid-back appearance due to the fact that they are herbivores（食草动物）

and mainly feed on juicy eucalyptus leaves， which take a lot of time and energy to

digest.

What is amazing is that because they often live in a dry and hot environment， they

drink very little water. 3 Well， scientists have discovered that these wild mammals

lick running water off the smooth surface of a tree trunk when it is raining. This

phenomenon is called “stem flow”.

Valentine Melba， the lead author of the research from the University of Sydney， told

the BBC， “I think the main message is that behavioral observations in the wild are very

important to establish what is normal and what is unusual， and to truly understand what

animals need. 4 ”

5 However， these sleepy creatures do need a drink sometimes. And if we're to

encourage them to grow well， we need to conserve their habitat.

A. So， how do they survive？

B. If we watch them carefully， they will tell us.

C. These adorable-looking creatures appear friendly and easy to control.

D. Maybe it is their ability to sleep for up to 22 hours a day.

E. A lot of koalas lost their lives in the bushfires in 2019.

F. The word “koala” means “no drink” or “no water”.

G. It's no wonder that people are concerned about the future of the species.

Task 2

On a hot summer day， nothing tastes better than a nice slice of watermelon.

Understanding the best growing conditions for watermelons will help you grow this

wonderful fruit.

1 The plants do all the work. They grow great in the south during warmer seasons，

so if you live in the north， you can follow the given tips to succeed.

Firstly， you should start early varieties in the house and plant transplants （移植物）

instead of planting seeds directly into the soil. Watermelons prefer sandy soil over

others. 2 Another tip is that the transplanted watermelon seedlings （幼苗） should be planted

2 to 3 feet apart. You should definitely include 7 to 10 rows between. 3 But don't

start them too early because large growing watermelon seedlings don't do well when

transplanted.

When thinking about how to grow watermelons， you want to be sure that you keep

the area free from weeds. A good， shallow hoeing （锄地） is best. 4 And you

certainly don't want to cut any shoots off the main plant. Another thing to think about

when considering how to grow watermelons is that they need plenty of water. You should

especially give them water when it gets dry， as it often does in the dead of summer.

5 If the bottom where it sits in the soil is yellow， the watermelon is probably ripe

for you to enjoy.

A. You do not want to disturb the roots.

B. Growing watermelons is not that difficult.

C. The plants should be started indoors and then put outside.

D. Growing watermelons takes about 120 days from start to finish.

E. You can also transplant a seedling that has been started indoors into the soil.

F. Growing watermelons also requires space as the plants spread on the ground.

G. Growing conditions for watermelons include lots of sunshine during the day and

warm nights.

Task 3

Studying abroad is full of adventures. To get the most out of your time with your host

family， check out our tips.

Be open and communicative.

You are allergic to peanuts， don't like seafood， or have a fear of dogs of all sizes？

1 They should know the most important facts about you from your paperwork， but

some things cannot be stressed enough—especially when it comes to health issues.

Accept the differences.

You will probably have to get used to different food and house rules that are not the

same as back home. Remember： different， new， and not the same don't have to mean

bad. Things are done in other ways around the world. As long as everything works， this

is a good thing of the learning experience. 2 Get to know your host family.

Be interested in what your host family works， eats， or does for fun. Ask questions，

be curious， and try to learn about and from them. It's the best way to discover a different

culture and practice your vocabulary. 3Mind your manners. 4 Keep your room clean. Don't leave the dishes in the sink or the empty milk jugs

in the fridge. Help carry the groceries from the car to the house. Do not sleep all day

Sunday and complain that there's no breakfast ready when you wake up.
