It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(随机地) from population, it is likely that their degrees of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degrees of intelligence.

Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures.
“The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long,” said lead author Margie Lachman, a psychologist. She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile (敏捷地).
But education early in adulthood does not appear to be the only route to maintain your memory. The study found that intellectual activities undertaken regularly made a difference. “Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education,” said Lachman.
The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with a mean age of 56 years. Almost 40 percent of the participants had at least a 4-year college degree. The researchers evaluated how the participants performed in two cognitive areas, verbal memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility. Participants were given a battery of tests, including tests of verbal fluency, word recall, and backward counting.
As expected, those with higher education said they engaged in cognitive activities more often and also did better on the memory tests, but some with lower education also did well, explained Lachman.
“The findings are promising because they suggest there may be ways to level the playing field for those with lower educational achievement, and protect those at greatest risk for memory declines,” said Lachman. “Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity (可塑性), and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectually active lifestyle.”

【推荐2】Old Fossils
Scientists have found what they think is probably the oldest fossil on Earth, a remnant of life from 3.7 billion years ago when Earth's skies were orange and its oceans green.
In a newly melted part of Greenland, Australian scientists found the leftover structure from a community of microbes(微生物) that lived on an ancient seafloor.Based on their analysis of the fossils, the researchers determined that they are 220 million years older than those discovered in Western Australia, which were 3.48 billion years old.
The discovery shows life may have formed quicker and more easily than once thought, about half a billion years after Earth formed.And that may also give hope for life forming elsewhere, such as Mars, said study co-author Martin VanKranendonk of the University of New South Wales and director of the Australian Center for Astrobiology.“It gives us an idea how our planet evolved and how life gained_a_foothold，” VanKranendonk said.
Scientists had thought it would take at least half a billion years for life to form after the molten Earth started to cool a bit, but this shows it could have happened quicker, he said.That's because the newly found fossil is far too complex to have developed soon after the planet's first life forms, he said.
In an outcrop of rocks that used to be covered with ice and snow which melted after an exceptionally warm spring, the Australian team found stromatolites(叠层石), which are layered structures that are often produced by a community of microbes.The stromatolites were about 1 to 4 centimeters high.
“It is like the house left behind made by the microbes，” VanKranendonk said.“Scientists used the layers of ash from volcanoes and tiny zircon(锆石) with uranium and estimated that they date back to 3.7 billion years ago.”
The dating seems about right, said Abigail Allwood, a NASA astrobiologist who found the previous oldest fossil, from 3.48 billion years ago, in Australia.But Allwood said she is not completely convinced that what VanKranendonk's team found once was alive.She said the evidence wasn't conclusive enough that it was life and not a geologic quirk(地质巧合)．“It would be nice to have more evidence, but in these rocks that's a lot to ask，” Allwood said in an email.

【推荐3】These are instructions for making invisible ink using baking soda.
| Difficulty: | Easy |
| Time required | A few minutes |
| What you need | Baking soda Paper Water Light bulb Paintbrush Measuring cup Purple grape juice |
| Here’s how: | There are at least two methods of using baking soda as invisible ink. Mix equal amounts of water and baking soda. Use a paintbrush to write a message onto white paper, using the baking soda solution (溶液) as “ink”. Allow the ink to dry. One way to read the message is to hold the paper up to a heat source, such as a light bulb. The baking soda will cause the writing in the paper to turn brown. The second way to read the message is to paint over the paper with purple grape juice. The message will appear in a different color. |
| Tips: | If you are using the heating method, avoid igniting (点燃) the paper. Baking soda and grape juice react with each other in an acid-base (酸碱) reaction, producing a color change in the paper. Grape juice concentrate (浓缩物) results in a more visible color change than regular grape juice. |
1. ______ is not needed for making invisible ink.

【推荐1】It is 2018; e-books are loved by many people. Do you read them?
An e-book is an electronic book, which can be made from common books and loaded onto an e-reader. The e-reader is a mini-device, just like a cell-phone. It has a touch pad screen and can hold a few hundred e-books. People can read e-books on it just like they do a book. So it is possible for people to read anywhere with an e-reader. This is perfect news for people who love to read books but can’t carry many.
Another great thing is that people can read books on it quickly and there’s no need for two hands to hold the book and turn pages. Most e-readers also have a nightlight, so you can read at night and don’t wake your partner with a big light on.
Not all book authors agree to make their books into e-books. The creator of Harry Potter says that her books will never be e-books. However, lots of authors absolutely love the idea and feel it’s the next step to keep books alive.
Nowadays e-books are sold in many websites, from where you can buy and load them onto your e-reader. Those websites look just like ordinary online bookstores and have a list of best sellers and a new book section. There is also a clear price on each e-book to make sure people can buy them like buying common books.

【推荐2】Many people who want to lose weight often choose to go on a diet. But is this really the best way? With celebrities (名人) speaking about new diets that have helped them become slim (苗条的) in advertisements (广告), more and more people are turning to dieting. Some shops begin to sell diet products such as diet milkshakes, snack bars and even diet pills. However, such popular products and diets are often found to be extremely unhealthy.
Most of these popular diets work by cutting down on a certain nutrient (营养素) from your food intake (摄入量). For example, some diets work by cutting down on carbohydrates (碳水化合物). This means the body must use its fat reserves for energy. This might help you lose weight. However, by cutting a particular food group out of your diet, you are starving your body of a nutrient that it needs, which could leave you feeling weak, tired or even bad-tempered. Besides, these diets are often unsuccessful in the long run.
Generally, one of the most effective ways of losing weight is to cut down on calories. The recommended (推荐的) calorie intake for an adult male is 2,500. If a man consumes more than 2,500 calories each day, then he is likely to gain weight. However, if he consumes less, then he is likely to lose weight.
In fact, proteins, carbohydrates, fats, vitamins and minerals all play an important role in staying healthy, which is why they all should be included in your meals. Of course, some foods can be eaten in moderation (节制) as an occasional snack. For example, a bar of chocolate every once in a while won't cause you any problems.
So, instead of spending money on popular diet pills or special weight loss foods, try to eat healthy balanced meals containing foods from all food groups. So, next time your friends tell you that they are going on a diet, tell them that eating a healthy balanced diet is a much better choice.
1. What is the author's opinion about the popular diets mentioned in the passage?| A．They are useful for losing weight. |
| B．They are welcomed by celebrities. |
| C．They are not as healthy as people think. |
| D．They are replacing people's everyday meals. |

【推荐3】With the trans-Tasman travel now in place, many of us are dreaming of afternoons watching sunsets fall over New Zealand’s dramatic mountains and lakes. After a long time of lockdown, it’s an appealing prospect. One great way to see the sights without breaking the bank is to rent a camper（野营车）.
“It’s amazing to see the smaller towns and learn about what happens on an orchard（果园）or a farm while staying in my camper, ” says Karen Nisbet, a 38-year-old New Zealander who has spent more than four years on the road.
If you’ve never taken a camper trip before, you might be wondering what it’s like. In New Zealand, you can camp at many places if you have the right vehicle. “To be able to camp better, your vehicle needs to be certified as self-contained, ” says Andy Ford, who runs a business renting campers in Auckland and Christchurch. “That basically means you have a portable toilet, and you’ve got water and food supply on board. ”
“There is something to check before booking, because if you camp outside a campground without the proper certification, you can be fined. Even with a self-contained vehicle, it doesn’t mean you can camp anywhere, ” Mr Ford adds. Many cities and popular tourist destinations like Queenstown often have restrictions, as do areas marked for conservation.
The good news is that it’s easy to find a place to stay. NZ’s Department of Conservation has a website you can use to search for camping sites around the country, or you could use an app.
If you’re camping, it’s important to make sure you deal with your waste properly. Many camp-grounds will have a dump（垃圾场）nearby for convenience, but you may need to plan ahead.

Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I’m not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet a real pounding（追击）ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn’t kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn’t my idea of fun. Jogging is also a lonely pastime. Some joggers say, “I love being out there with just my thoughts” Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn’t just the first week: it was practically every day for two months. I never got past the pain level, and pain isn’t fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don’t jog any more, and I don’t think I ever will. I’m walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I’m getting exercise, and I’m enjoying it at the same time. I could never say the same for jogging, and I’ve found a lot of better ways to stay in shape.

One day Bob could not take it anymore. He handed in his resignation(辞职信) to the boss and complained that the boss did not value hard-working workers.
The boss knew that Bob didn’t work hard for the company all these years, but in order to help Bob to realize the difference between him and Jack, the boss asked Bob to do the following. “Go and find out if there is anyone selling watermelons in the market.” Bob went, returned and only said, “Yes.” The boss asked, “How much per kilogram?” Bob went back to the market to ask and returned to answer, “$12 per kilogram.”
The boss told Bob to ask Jack the same question. Jack went, returned and said, “Boss, only one person is selling watermelons. $12 per kilogram, $100 for 10 kilograms. He has 340 melons in all. On the table are 58 melons, and every melon weighs about 15 kilograms, bought from the South two days ago. They are fresh and red.”
Bob realized the difference between himself and Jack. He decided not to leave but to learn from Jack.
My dear friends, you know, a more successful person is more careful, thinks more and understands in depth. For the same matter, he sees several years ahead, while you see only tomorrow. The difference between a year and a day is 365 times, so how could you win?

【推荐1】If you are a teenager without a job, you probably do not have much extra money. Sometimes parents will give their children a pocket money for doing small housework, but it is often not enough once the children grow into teenagers and want to do things with their friends all of the time. How to make money is an important thing for teens to learn. If you’re wondering how a teenager can make good money, some ideas might be:
Getting a part-time job at a local restaurant or store is always a sure way to make money as a teen. But getting a job somewhere like this might be hard, considering many jobs in local stores are being taken by adults more and more often.
Doing landscaping (绿化) is something that most adults do not like to do, and teens can usually find jobs around their neighborhood doing the landscaping of friends and family.
Some teens are good at something such as writing or photography. These teens can make money by doing things such as writing articles for newspapers or magazines or selling their photos online.
Teens who live in a country area can earn money by helping out on farms, or they can try raising their own animals such as chickens, and selling them or their products.
Looking for jobs can seem hard at first, but if you have a try, it should not be too hard to find a job or way to make money.

【推荐2】Ecofriendly Vauban, lied in the southwest part of Germany, has everything—treelined streets, perfect houses—but it's missing one urban feature of the last 100 years or so: the car. And Vauban residents don't mind one bit. Vauban doesn't ban cars entirely. Rather, it just tries to reduce the use of cars by creating "parkingfree" and "carfree" living. In Vauban, parking spots are a nono private property. Cars can only be parked in public parking lots, so living without a car saves residents the cost of parking in the public lot. Cars also are prevented from using certain roads and must stick to strict speed limits. With these limitations, fewer than 20 percent of residents own cars. And now, with a population of 5,500, it's attracting attention from around the world. Can an ecofriendly city like Vauban be a model for Americans to stop their over reliance on the cars?
Sometimes when I watch a news report what's in the back of my mind is what isn't being reported or stressed. While this ecofriendly city is inspiring in that it shows residents getting exercise and fresh air through the majority use of bicycles, as well as good oldfashioned walking, common sense would tell you that even for a place like Vauban, Germany, it owes its existence to the cars.
Do you think that bicycles were able to transport all the construction materials that were needed to build and maintain the ecofriendly homes and businesses in Vauban? It took cars to help build this city. It's one of the paradoxes of life that sometimes in order to get away from relying on something like the car, you actually have to rely on that very thing at the beginning and into the foreseeable future to some degree.
I myself haven't owned a car for more than 14 years, and mostly get around town running, walking, or using public transportation. There are times I wish I had one, since it would make many things easier, but overall I'm glad not to have to deal with the headaches of owning a car, which caused me to get rid of it in the first place. And all the walking and running has helped to keep me fit and healthy. To get even close to being like ecofriendly Vauban, Americans will need to absolutely change the way they live. Commuting (乘车上下班) patterns will have to change, public transportation will have to be invested in, and so on. And though ending our love affair with the car will be impossible during my lifetime, we may at least start to see more Vaubanlike areas in the USA.
We can hope that Americans will consider using their feet more to get around, cutting down on pollution, and giving themselves some more exercise.
1. Why don't over 80% of the residents in Vauban own car?| A．The streets there are very narrow. |
| B．There are many limitations on the use of cars. |
| C．The government limits the number of cars. |
