“Children who eat three or more hamburgers a week are more likely to suffer from asthma (哮喘),” researchers say. However, they say that the risk may not be caused by the meat-rich diet itself, but by a lack of fresh fruit and vegetables.
The study looked into 50,000 children from 20 countries. Parents were asked about their children’s eating habits and whether they had ever suffered from asthma. The effects of their diet seemed to be different depending on where they lived. Fruit and vegetables are more helpful in less rich parts of the world, while eating lots of fish was more helpful in richer countries. Eating at least three hamburgers a week was linked to a greater risk of asthma, but only in wealthier countries.
Dr. Gabriele Nagel said different things may cause asthma in different parts of the world. “This gives us more understanding of how asthma affects different people, and its effects in developing as well as developed countries,” she said.
High levels of unhealthy fat in hamburgers could increase the risk of asthma. However, the researchers said children who ate several hamburgers a week might have other unhealthy lifestyle habits as well.
Researchers said the study helped us understand how asthma and diets are connected. “Previous (先前的) studies have shown that a diet rich in fruit and vegetables can help to reduce a child’s risk of developing asthma symptoms (症状),” Dr. Elaine Vickers said. “Our advice to parents is to make sure that children have a healthy diet and also get plenty of exercise.”

Energy goes from one plant or animal to another. A food chain shows how this energy moves. Each time an animal gets eaten, its energy is passed onto the animal that eats it. The food chain is very important because it keeps the balance of nature. If one part of the food chain disappears, it can affect all the other plants and animals. Any threat to the food chain is a threat to the environment’s biodiversit(生物多样性). The food chain helps keep animal populations in balance. However, if something happens to increase or decrease one of the links in the food chain, that balance is broken. If one animal becomes endangered, it puts all the animals above it at risk.
Some of the threats are natural, such as wildfires, hurricanes, tornados, floods and so on. But the biggest threats to the food chain come from you and me. These threats include overhunting, overfishing, logging, farming, development, pollution, etc. The food chain is endangered anywhere humans have had an effect on the natural environment.
A recent study shows that the overfishing of large sharks is damaging the food chain along the US Atlantic coast. Canadian and American scientists say sharks are being killed in great numbers for their meat and fins(鳍). Now, not enough sharks are around to eat the cownose(牛鼻) ray. The ray’s population has increased and they have eaten up the shellfish to the point where it has hurt commercial(商业的) fishing.
Many of us disturb the natural environment in our own backyards. It’s up to us to take care of the environment and try not to disrupt the natural food chain. If we don’t act responsibly, animals will start disappearing.
1.What can we learn from Paragraph 1?
A.The food chain is not easy to be broken.
B.The energy of an animal usually disappears when it dies.
C.Increasing the links will not break the balance of nature.
D.Breaking the food chain is bad for the biodiversity of the environment.
2.The study mentioned in Paragraph 3 proves that .
A.human activities can be a big threat to the food chain
B.we are all responsible for the breaking of the food chain
C.natural disasters are hard to break the food chain
D.hunting large sharks for meat is beneficial
3.We can infer that the writer wrote this passage mainly to .
A.explain what the food chain is
B.tell us something interesting about Nature
C.suggest that we stop eating meat to save animals
D.suggest that we not disrupt the natural food chain

Many of us spend part of each day surrounded by strangers, whether on our daily commute (上下班往返), or sitting in park or cafe. But most of them remain just that-strangers. However, new evidence has shown that plucking up (鼓起) the courage to strike up conversation might be good for our health.
Nicholas Epley from the University of Chicago and Juliana Schroeder from the University of California are behavioural scientists. They wanted to know whether solitude is a more positive experience than interacting with strangers, or if people misunderstand the consequences of distant social connections. They found that many people feel uncomfortable and frightened talking to others and their research suggested that when we make an initial conversation “we consistently underestimate (低估) how much a new person likes us.” It seems we think that all the things could go wrong and why someone wouldn’t want to talk with us.
Their research involved an experiment with a group of Chicago commuters and found that “every participant in our experiment who actually tried to talk to a stranger found the person sitting next to them was happy to chat.” From this and other research, the conclusion is that connecting with strangers is surprisingly pleasant and it has a positive impact on our wellbeing. It’s true that talking can make you feel happier and happiness can lead to better mental health.
However, if you’re’ an introvert (性格内向者), the thought of speaking to someone new might make you anxious. But the American research found “both extroverts (性格外向者) and introverts are happier when they are asked to behave in an extroverted manner.” So maybe, if you’re a loner, it’s time to come out of your shell and make some small talk with a stranger-it could be the beginning of a new friendship.
1.What does the underlined word“solitude”in paragraph 2 mean?
A.Being calm. B.Being pleasant. C.Being alone. D.Being healthy.
2.Why might we not want to speak to a stranger?
A.Because we don’t trust a new person.
B.Because we can’t find a common topic.
C.Because we like distant social connections.
D.Because we carry a negative voice in our head.
3.What could help start a new friendship?
A.Making a small talk. B.Sitting next to a stranger.
C.Sharing personal details. D.Behaving in polite manner.
4.Which of the following is the best title for the text?
A.How to be an extrovert. B.Talking to strangers.
C.How to speak to strangers. D.Making new friends.

In recent years there has been a steady attack on salt from the doctors; salt is bad for you-regardless of your health. Politicians also got aboard."There is a direct relationship" US Congressman Neal Smith said "between the amount of sodium (钠) a person consumes and heart disease circulatory(循环的)disorders stroke and even early death."
Frightening if true! But many doctors and medical researches are now beginning to feel the salt scare has gone too far."All these remarks and cry about salt is unnecessary" Dr. Dustan. insists. "For most of us it probably does not make much difference how much salt we eat." Dustan's most recent short-term study of 150 people showed that those with normal blood pressure experienced no change at all when placed on an extremely low-salt diet or later when salt was reintroduced. Of the hypertensive (高血压的) patients however half of those on the low-salt diet did experience a drop in blood pressure which returned to previous level when salt was reintroduced.
"An adequate to somewhat excessive (过度的)salt intake has probably saved many more lives than it has cost in the general population" said Dr. John H Laragh. "So an opinion that the whole population should avoid salt makes no sense."
Medical experts agree that everyone should practice reasonable “moderation” (节制)in salt consumption. For the average person a moderate amount might run from four to ten grams a day or roughly 1/ 2 to 1/3 teaspoons. One to two grams of salt would come from the natural sodium in food. The rest would be added in processing preparation or at the table.
"Na is not your enemy "says Comek’s Dr.Laragh. "Salt is the No.1 natural component of all human tissue and the idea that you do not need it is wrong. Unless your doctor has proven that you have a salt-related health problem,,there is no reason to give it up. "
1.What did Neal Smith think of eating salt?
A.It was necessary.
B.It could lead to some diseases.
C.It was not related to heart disease.
D.It should be guided by the government.
2.What can we infer from Dr. Dustan's study?
A.It's reasonable to have the salt scare.
B.A low-salt diet may be good for some people.
C.The reduction of salt consumption can cure a hypertensive patient.
D.The amount of salt consumption has nothing to do with one's blood pressure.
3.What advice does Dr Laragh give in Para 3?
A.Experts should promote their study of salt.
B.Patients should eat adequate amounts of salt.
C.Doctors should not advise patients to avoid salt.
D.People should not be afraid of taking a bit excessive salt.
4.What does the author mainly want to tell us in the text?
A.The salt scare is still on.
B.Salt consumption has caused many problems.
C.The moderate use of salt is recommended.
D.The cause of hypertension is now understood.

A recent study showed that disordered eating has negative effects on health including lower self-evaluation of health, which isn’t too surprising. What was really shocking was how common the disordered eating behaviors seemed to be in our culture.
Individually, these behaviors aren’t something to be overly concerned about, but when they add up, it became a roadblock to healthy living. Ask yourself the right questions to find out if you, too, have gone beyond healthy habits and worry about your weight.
For example, starchy(含淀粉的) foods can make people feel uneasy about eating them. Sometimes an ingredient, like fat, causes anxiety, even if it’s used to make healthy foods like olive oil. If you’re skipping foods and blaming it on an allergy(过敏) reason, but your real motivation is to lose weight, that’s a red flag.
A strict eating schedule might seem like a smart way to provide structure throughout your day, but overdoing it can leave you feeling hungry.
Not having control over how your food is prepared can be a concern, especially if you have food allergies. It’s when that anxiety is baseless and prevents you from otherwise enjoying a night out that it becomes a problem.
Tracking calories can be a useful tool to understand which foods are rich in calories, which ones aren’t, and what calorie range you should be eating. If it becomes overbearing, it’s no longer a healthy method. It’s the right way to pay attention to your hunger and satiety(饱足), and rely on those to decide when to start and stop eating.
Disordered eating is common, but it’s not harmless. Seek out help if you see yourself in these behaviors, and make sure you recognize the signs that you’re already at a health weight.
1.What does the underlined part “a red flag” in the third paragraph mean?
A.A good means. B.A negative attitude.
C.A warning sign. D.A normal situation.
2.What’s the main idea of the passage?
A.Tracking calories can be a useful tool to keep fit.
B.Disordered eating is common but harmful.
C.Skipping foods won’t help you lose weight.
D.Knowing how your food is prepared can be beneficial.
3.If you have disordered eating problems, you’d better ______ accordingly.
A.avoid starchy foods B.lose weight
C.prepare your food well D.turn to the doctors
4.The author proves her point by ____________.
A.using examples B.making a comparison
C.asking and answering D.analyzing causes and effects

The government's top Great Barrier Reef scientist says a third mass coral bleaching (珊瑚白化) event in five years is a clear signal that the marine wonder is “calling for urgent help on climate change. Corals can recover from mild bleaching, but severe bleaching can kill corals.
Prof Terry Hughes, director of the Centre of Excellence for Coral Reef Studies at James Cook University, surveyed 1,036 reefs from a plane over nine days in late March.
The marine park authority also had an observer on the flights. The survey has released maps showing that serious levels of bleaching occurred in 2020 in all three sections of the reef northern, central and southern. Some 25% of the reefs were seriously bleached-meaning that more than 60% of the corals on each reef had bleached.
The Great Barrier Reel has experienced five mass bleaching events-1998. 2002,2016, 2017 and 2020 -all caused by rising ocean temperatures driven by global heating. Hughes said there probably would not be the same level of coral death in the north and central regions in 2020 as in previous years, but this was partly because previous bleaching outbreaks had kill off the less heat -tolerant species The 2020 bleaching was second only to 2016 for severity(严重性), Hughes said.
Dr. David Wachenfeld,chief scientist at the Great Barrier Reef Marine Park Authority, told Guardian Australia "My greatest fear is that people will lose hope for the reef. Without hope there's no action. People need to see these bleaching events, They are clear signals that the Great Barrier Reef is alling for urgent help and for us to do everything we can”.
Measures to improve the ability of recovery of the reef include improving water quality, controlling outbreaks of coral-eating starfish, and research and development to improve the heat tolerance of corals. " However, climate change brings a new scale of impact unlike anything we have seen before. Thus, dealing with the climate problem is the basis for everything else to work, ” Wachenfeld said.
1.What does the underlined word “mild” in Paragraph 1 probably mean?
A.Serious
B.Strong.
C.Steady.
D.Slight.
2.What can we learn from Paragraphs2 & 3?
A.The majority of the corals on each reef were bleached.
B.The survey was carried out on a plane by Hughes alone.
C.The 2020 bleaching killed off the less heat tolerant species.
D.The 2020 bleaching was worse than those of all the previous years.
3.We can infer from Wachenfeld’s words that people seeing the bleaching events .
A.have done everything they can for the reef
B.are sure to lose hope for the reef
C.will care more about the reef
D.will have no action at all
4.Which is the essential measure to improve the ability of recovery of the reef?
A.Improving water quality.
B.Making efforts to prevent global warming.
C.controlling outbreaks of coral-eating starfish.,
D.Doing research on the heat tolerance of corals.

Ocean food plays a very important part in our food supply. Not so long ago, the world’s oceans were filled with different types of fish. Now, a large increase in global overfishing has threatened that supply.
According to the United Nations Food and Agriculture Organization, 90 percent of the world’s fisheries (渔场) are either being fully exploited (开发), or are at risk of being closed down.
With fish supplies running out at home, fishermen are traveling further to find their catch. Frequently, fishermen are crossing over into other countries. As fish supplies closer to their homeland’s shores are decreasing fishermen cross borders to find fish.
Overfishing can be found everywhere, from Mexican fishing boats off the US coast of Florida to Russian fishing boats in the western Bering Sea. However, the effect is felt the strongest in the South China Sea.
On the other side of the world, West Africa is now seeing malign effects of overfishing. For coastal African countries, such as Senegal, the fishing industry is a large part of the national economy. The World Bank reports nearly 20 percent of the Senegalese are working in the fishing industry. Rashid Sumaila is the Director of Fisheries Economic Research at the University of British Columbia. He says communities that depend on fish for income and food, like Senegal, are now at risk.
1.Why do fishermen cross borders to catch fish?
A.Because they want to protect the environment.
B.Because they want to enjoy the overseas scenery.
C.Because fish supplies in their countries are decreasing.
D.Because fishing is not allowed in their own countries.
2.Where can the most serious overfishing be seen according to the text?
A.In Russia. B.In the South China Sea.
C.Off the US coast of Florida. D.In the western Bering Sea.
3.What does the underlined word “malign” in the last paragraph probably mean?
A.Harmful. B.Satisfying.
C.Hopeful. D.Beneficial.
4.What can be inferred from the last paragraph?
A.Most people in Africa will be out of work.
B.The World Bank will lend money to fishermen.
C.Rashid Sumaila is unconcerned about overfishing.
D.Overfishing has some bad effects on African people.
