試題詳情
Whales are the largest living organisms （生物）living on the surface of the earth.An adult blue whale weighs up to 173 tonnes with 30 meters in length.When a whale dies in the ocean，its body usually falls to the sea floor and a special deep-sea ecosystem will be formed in a long time.Scientists give a name to this：the whale fall.
Recently，some scientists on a Chinese research ship called Tansuo-1 found a whale fall at the depth of 1，600 meters in the South China Sea.Whale falls are seldom found by humans.This is the first time China has found this type of ecosystem.So far，less than 50 modern natural whale falls have been found by humans around the world.
The whale fall is really important to deep-sea animals，as it provides food for them.Usually，the whale fall goes through three stages.The first stage comes just after the whale dies.The body attracts lots of big sea animals such as shark and they come to eat the body.This stage lasts from months to years.At the second stage，smaller animals come for the whale's bones and leftovers.This stage can last one or two years.Bacteria （細(xì)菌）play a role at the third stage.They break down what has been left.This stage can last as long as 100 years.
The whale fall found in the South China Sea is 3 meters long.It is still at the first stage.The scientists said it would take them a long time to study the whale fall because they knew it would help them understand the deep-sea ecosystem better.

A．a(chǎn)re saved by scientists
B．a(chǎn)re found on the beach

（2）The Chinese meaning of the underlined word "ecosystem" is BB.
A．經(jīng)濟學(xué)
B．生態(tài)系統(tǒng)
C．電子信息
D．環(huán)保體系
（3）The whale fall goes through the following stages，and the correct order is CC.
①Bacteria break down the rest of the whale.②Smaller animals eat the whale's bones.
③The whale dies in the ocean.④Big sea animals eat the whale's body.
A． ③④①②
B． ④③①②
C． ③④②①
D． ④③②①
（4）According to the passage，we know that AA.
A．a(chǎn)n adult blue whale weighs up to 173 tons
B．some scientists found a whale fall in the South China Sea
C．a(chǎn)t the first stage，smaller animals come for the whale's bones

1．How do you feel about nature？After spending hours indoors，do you feel better when you visit your local park？I believe the answer must be "YES".
Most people think that nature is good for our bodies and brains.However，humans are spending more time inside and less time outside.For example，the number of visitors to Canada s national parks is getting smaller every year.And in countries such as the USA，only 10% of teenagers spend time outside every day.Many doctors feel that this is a problem in the twenty-first century.
Therefore，some doctors are studying the connection between nature and health：one example is the work of Dr.Matilda in Sweden.The doctor gave people a math test.During the test，their heart rates（心率） were fast.After the test，one group of people sat in a 3 D- virtual-reality（虛擬現(xiàn)實） room for fifteen minutes with pictures and sounds of nature.Their heart rates were slower than people's in the other group.The virtual touch with nature helped them feel more relaxed.The natural world allows our brains to rest and slow down，and can leave us feeling happier and less stressed.Another example from Canada also shows nature is good for health.In Toronto，researchers studied 31，000 people living in the city.In general，they found that healthier people lived near parks.
Because of studies like these，some countries and cities want people to enjoy nature in their everyday life.In Dubai，people plan to build a new shopping mall with a large garden，so shoppers can relax outside with trees，plants and water.And South Korea has new forests near its cities and around 13 million people visit these forests every year.Getting close to nature has been thought to be necessary for brain development in children.In Switzerland， "forest schools" are popular.School children study their subjects in the forests and exercise a lot outside.So after building cities for so long，perhaps it's now time to start rebuilding nature.
In a word，nature holds a special kind of energy：it is clean，wild and spirit- renewing.jye.ai makes us grow stronger.
（1）What is the purpose of Paragraph 2？
A．To raise the problem of people's lifestyle.
B．To offer some advice for people's lives.
C．To share people's ideas about nature.
D．To show people's lives in different countries.
（2）What do the results of the studies in Paragraph 3 mainly show？
A．More healthier Canadians live close to parks.
B．The math test is difficult and makes people nervous.
C．Nature can relax people and influence them positively.
D．People's heart rates increase in a 3 D virtual-reality room.
（3）To help people enjoy nature，countries do the following except.
A．rebuilding nature near cities
B．having classes and doing sports in nature
C．planning a green area for shoppers
D．starting a brain development programme
（4）Which of the following sentences can be best put in the blank？
A．So why not run away from the cities？
B．So nature is our best choice，isn't it？
C．So why not let nature be part of our daily life？
D．So nature is more important than cities，isn't it？發(fā)布：2025/1/5 10:0:6組卷：5引用：1難度：0.1 -
2．It's good to share，right？Growing up as kids we are told to share our toys and not be selfish.We also live in an age where discussing our feelings is encouraged.But when does it all become too much？With new fashion trending all the time，such as dance challenges and wearing a pillow as a dress，the question is：when can sharing become oversharing on social media？
What is oversharing？The term has become related to social media，but it doesn't only belong to this platform.Imagine you head to a party and you meet someone.Within five minutes they have told details about their personal life.While some of us may try to escape these people，according to marriage therapist Carolyn Cole，this form of oversharing could come from a strong desire to connect with someone.But how does this translate to social media？
Dr.Christopher Hand，a lecturer in internet psychology，says the more details people share，the less sympathy" we express when things go wrong.This could be due to a belief that we attract our own negative experiences the more we share them.It seems that sadfishing，the idea of searching for sympathy by oversharing，is generally considered as negative rather than the cry for help it could actually be.
However，Dr.Hand's research also seems to suggest that the more we post on a platform，the more socially attractive we become- if the posts are positive.Even back in 2015，Gwendolyn Seidman PhD，said that we should avoid complaining and being negative online.We should also control clear of showing off or bragging"，as it's now known--especially about our love lives.It makes sense- if your date is going "that well"，would you really have time to share a photo with text？
So，how can you know if you are oversharing？Well，why not ask your friends in real life.They would probably be more than happy to tell you if your posts about your breakfast or your gripes about your lack of money really are too much.
（1）The phrases "dance challenges" and "wearing a pillow as a dress" in paragraph 1 are used to prove.
A．a(chǎn) dislike of oversharing
B．a(chǎn)n enthusiastic interest in oversharing
C．social media becoming free
D．oversharing being forbidden
（2）According to Carolyn Cole，why do people overshare？
A．Need to connect with people.
B．Curiosity to know others.
C．Desire to help others.
D．Ambition to succeed.
（3）What can be inferred about oversharing from paragraph 3？
A．Sadfishing is generally considered as positive.
B．We might be in danger when bad things happen.
C．People don't feel sorry as much when things are wrong.
D．Become more socially attractive no matter what happens.
（4）What is Gwendolyn Seidman's attitude towards showing off？
A．Negative.
B．Neutral.
C．Positive.
D．Indifferent.發(fā)布：2025/1/5 10:0:6組卷：1引用：1難度：0.2 -
3．We like to believe that before we make a decision，most of the time，we take time to consider all the facts carefully.However，experts believe that only 5% of our decisions are based on a rational thought process.So，what influences our decision- making process？
We often leave decision-making to our instincts".Scientists have found out that if we had the choice，we like to avoid pain rather than get somethjye.aig.In fact，we're twice as happy when we try to avoid a bad situation than when we experience a good one.This is why when companies send ads，they use phrases like "How to avoid ..."，"Don't miss out!"，etc.
There are also physical reasons that affect our decision- making.Psychologist John Bargh carried on an experiment where people were asked what they thought of a fictional person，while holding a cold or a hot cup of coffee.Those holding the hot cup believed the person to be warmer and more sociable than those holding the cold cup.So，when temperatures rise，the more likely we are to believe in strangers.
Stress is another thing which affects our decisions.Different situations are more or less stressful for different people.Researchers have found，though，that women are more conservative about decisions when stressed，while men are to make riskier choices.
It may come as a surprise but every day from the minute we get up，we have to make countless decisions，like what to wear，what coffee to have and so on.Each choice makes our brain a little bit more tired，and this affects our decision- making.That's why important people，like presidents wearing the same three suits all the time，want to limit the small choices and spend more brain power on the bigger ones.
（1）Which of the following shows the structure of the passage？
A.
B.
C.
D.
（2）What is the main idea of the last paragraph？
A．Every day we have to make lots of big decisions.
B．People sometimes judge a person by what he wears.
C．What people wear influences their decision making.
D．Making fewer decisions helps to save brain power.
（3）What can we learn from the passage？
A．We make most of the decisions after our careful thinking.
B．People are likely to be happier to avoid something bad.
C．As the temperature is low，we are likely to believe others.
D．People usually have risky decisions under heavy pressure.
（4）The purpose of the passage is to.
A．tell us what influences decision making
B．a(chǎn)dvise people to make rational decisions
C．warn people not to make risky decisions
D．show disadvantages of rational decisions發(fā)布：2025/1/5 10:0:6組卷：14引用：2難度：0.2
