1 . What’s the first thing you remember doing? It could be playing with your friends at school, or going to a birthday party and eating amazing cake.
It’s a strange concept to grasp, but according to research, about four out of ten of us invent our first childhood memory. Rather than having experienced something, we could have fabricated a fake memory from videos or photos we’ve seen. We could have been influenced by a story recounted to us that spurs our minds on to adopt someone else’s memory as our own.
So why do we create fake memories? Some experts believe that there is a clear desire for a sense of self and having a cohesive (连贯的) story of our existence.
So, the next time someone says they have a clear memory from when they were one or even before just remember that while it could be true, there’s a chance they just invented it at some point in their lives.
A.But why don’t we have clear memories from that age? |
B.It happens to everyone no matter how educated he or she is. |
C.This is possibly due to the rapid creation of brain cells in our early years. |
D.We often talk about these memories with our families as if it were what happened yesterday. |
E.Creating memories can fill in the gaps giving us a more complete structure for our early lives. |
F.Most of us have a treasured early memory of our childhood, but can we really believe those vivid memories? |
G.What it means is that memories of our younger years, especially before the age of two, may be inaccurate, or entirely false. |
2 . Beauty and Well-being Benefits of Handed Massage Guns
What are they?Originally beloved by athletes, massage guns are gaining popularity as a stress or pain-relieving tool. A quick and convenient alternative to a traditional deep-tissue massage, many offer detachable heads to target calves, ankles or the top s of shoulders, available in a range of sizes and speeds.
What are the supposed benefits?If you often find yourself aching after the gym or a long day of work, a massage gun may well be your new best friend. Sending pulses at a steady frequency that is difficult to achieve manually, they allow you to target a specific area of tightness, loosening lactic acid buildup muscle and allowing for greater mobility and muscle flexibility. Even if you’re not so physically active, a couple of minutes of regular massaging can do wonders for your complexion.
Through vibration frequency, the movement of a massage gun will encourage blood and lymphatic (淋巴的) circulation, giving a new vibrancy and comfort to skin as toxins (毒素) drain out and oxygen flows through. If you’ve been feeling heavy or struggling to unwind, massage guns are also thought to be a useful tool in the rehabilitation (康复) of depression, anxiety, digestive disorders and stress-related insomnia.
Do they actually work?Once you get used to the quiet humming noise, the swift, targeted relief a gun can offer more than justifies the initial spend. Leading the market is the Lola, a lightweight handheld gun in a sleek matte finish with four speeds that tucks easily into the pocket of an overnight bag. The key is to operate within your own comfort-be sure to fit the adjustable heads firmly and work through the speed functions slowly, building up to higher pressures only if necessary. While concerns about suitability for specific conditions or injuries should always be discussed with a doctor, the massage gun is certainly proof that both internal and external beauty can be achieved by listening that little bit closer to our bodies.

Balancing Trees and CO2
Tree planting used to be regarded as an effective means of reducing climate change. Perhaps it’s time for us to rethink this practice. Trees pull CO2 from the air. This effectively removes CO2 from the atmosphere. But trees only hold onto CO2 as long as they’re alive. Once they die, trees decay (腐烂) and release that CO2 back into the atmosphere.
Recent studies have found that trees around the world are growing faster than ever. The rise of CO2, mainly due to burning fossil fuels, is probably driving that rapid growth, said Roel Brienen, a forest ecologist at the University of Leeds, UK. High levels of CO2 are increasing temperatures, which in turn speeds tree growth in those areas, he added.
The faster trees grow, the faster they store carbon. It seems like good news. However, it is known that fast-growing tree species, in general, live shorter lives than their slow-growing relatives.
In order to see whether the growth-lifespan trade-off (生长与寿命之间的权衡) is a universal phenomenon, Brienen and his colleagues analyzed over 210,000 individual tree ring records of 110 tree species from more than 79,000 sites worldwide. They found that, in almost all habitats and all sites, faster-growing tree species died younger than slow-growing species, and even within a species, the trade-off between growth and life span held strong.
The team also created a computer program that modeled a forest and tweaked (微量调整) the growth of the trees in this model. Early on, it showed that “the forest could hold more carbon as the trees grew faster”, Brienen reported. But after 20 years, these trees started dying and losing this extra carbon again. “We must understand that the only solution to bringing down CO2 levels is to stop emitting (排放) it into the atmosphere,” said Brienen.

3. Read the following statement, underline the false part of it and explain the reason. The team has found that the faster trees grow, the faster they store CO2, and the longer lives they live.
