中考英语专题练习：短文填空(含答案)

Nowadays。many of us rely on technology to check the

weather forecast。whether it be through online sources。TV。or

the。However。if you find yourself in a n where these resources

are unavailable。looking at the clouds in the sky can provide some

insight。This can be particularly helpful for outdoor enthusiasts。such as hikers or campers.

The appearance of clouds can reveal a lot about the weather。Generally。white and high clouds are a sign of good weather。while dark and low clouds suggest rain or storms may be on the

way。Clouds can come in us colors。including black。white。and gray。each indicating something different about the weather。Black clouds indicate an approaching storm。though it may not

have strong winds。White clouds typically mean good weather。but a storm could still be on the horizon。Gray clouds usually

signify a new or light storm。but it may spread across a large area

and linger for some time。

Overall。being able to read the clouds can be a useful skill

for predicting the weather。especially when other resources are

unavailable.

When people want to know about the weather。they usually

turn to their s。TVs。newspapers。or the。However。there are

also many signs among wildlife that can indicate the weather。For

example。before a storm。field mice come out of their holes and

deer come down from the mountains.

Birds are also good weather indicators。Some birds e irritable

and will fight over a piece of bread。while others chirp and sing

just before a storm。It seems they know they won't have another

chance for one or two hours。You will sometimes see birds

getting together on a wire close to a building。This is because the

low pressure makes the air so thin that birds have difficulty flying.

We have no idea when humans first began using salt。but

throughout history。it has been used in many different ways。For

example。historical records show that people who lived three

thousand years ago used salt to preserve fish。In ancient Egypt。salt was used to preserve the dead。preventing their bodies from

decaying.

Another argument is that raw food is more natural。as

humans have been eating raw food for thousands of years。However。there are also risks associated with raw food。such as

the potential for foodborne illness.

Proponents of raw food diets argue that cooking destroys

important enzymes and nutrients in food。They believe that raw

food is more nutrient-dense and easier for the body to digest。However。some studies have shown that cooking actually

increases the availability of certain nutrients。such as lycopene in

tomatoes.

On the other hand。opponents of raw food diets point out the

potential for foodborne illness from consuming raw or

undercooked food。Raw food can harbor harmful bacteria。viruses。and parasites that can cause us illness。In fact。the

Centers for Disease Control and n (CDC) mends cooking meat。poultry。and eggs to a safe internal temperature to prevent

foodborne illness.

Overall。the debate over raw food diets is complex and there

is no one-size-fits-all answer。It is important to consider

individual health needs and risks when deciding whether to

incorporate raw food into one's diet。It is also important to

properly prepare and handle raw food to minimize the risk of

foodborne illness.

Vitamin C is a nutrient that is highly sensitive to heat。When

vegetables rich in vitamin C are cooked。the vitamin C content is

significantly ced。Similarly。B vitamins。although not as

abundant in vegetables as vitamin C。are also diminished when

exposed to heat.

Advocates of raw diets believe that consuming raw foods can

slow down the aging process。prevent diseases。and improve

overall well-being.

Interestingly。cooking certain foods can actually increase the

nutrient content。For example。cooking tomatoes increases the

levels of a nutrient that can lower the risk of heart disease and

certain cancers。nally。cooking can enhance the amount of

calcium in some vegetables.

Cooking has other benefits as well。A study conducted by

Harvard University found that cooking makes food easier to chew

and digest。and improves its overall energy value.

Ultimately。the most important thing is to simply make sure

that you consume fruits and vegetables。regardless of how they

are prepared。While cooking can affect nutrient levels。it is still

important to ritize consuming a variety of nutrient-rich foods.
