4 . Many children first learn the value of money by receiving an allowance (pocket money). The purpose is to let children learn from experience at an age when financial mistakes are not very costly.
At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget.
Paying children to do extra work around the house, however, can be useful. It can even provide an understanding of how a business works.
Allowances give children a chance to experience the things they can do with money.
Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future.
Requiring children to save part of their allowance can also open the door to future saving and investing.
That may not seem like a lot. But over time it adds up.
| A．Many banks offer services to help children and teenagers learn about personal finance. |
| B．They can share it in the form of gifts or giving to a good cause. |
| C．It is a good virtue for children to form a habit to learn how to save money. |
| D．The amount of money that parents give to their children to spend as they wish differs from family to family. |
| E．Parents are usually advised not to offer more money until the next allowance. |
| F．Parents are supposed to tell their children how they should spend their pocket money wisely but the refused to do so. |
5 . The two-week Harvard Pre-College Program is an intense and exciting experience of the college life. The admission committee is now looking for mature, academically motivated students who will graduate from high school and enter college in 2022.
The Course Experience
With over 30 courses to choose from, you’re sure to find a topic that interests you. Although courses are non-credit and do not have letter grades, you need to attend the class in its entirety. When class is not in session, you can participate in creative and social activities. At the end of the program, you’ll receive a written evaluation from your instructor, as well as a transcript (成绩单).
Time
·July 24 — August 5
How to Apply
Complete an online application and provide supplemental (补充的) materials, including:
·The $75 non-refundable application fee.
·Transcripts from 9th grade to fall 2021 grades: This can include progress reports, report cards, and educational summaries from your high school

6 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.
Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.
While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.
In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.
Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.
These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.
