When Gitanjali Rao shared how she likes “finding solutions to real problems”, it was hard to imagine this dynamic 11-year-old girl could settle a problem that has escaped scientists for years.

In just three months, Rao came up with a device（装置）that can replace the costly and lengthy tests currently used to reliably determine lead levels in our fresh water. Inspired by the current litigation （诉讼）in Flint, Michigan, a case of water pollution from 2014 to 2015, Rao designed a new testing system that resulted in her being named America’s Top Young Scientist for 2017.

Rao had been following the water problem for about two years. She was amazed by the number of people affected by lead pollution in water and wanted to do something to change this. Gitanjali spent months trying to convince local high schools and colleges to give her lab time to continue her experiment. At home, Gitanjali worked on her project in the “science room” she asked her parents to create for her. Rao has created a device that uses three parts: a cartridge, a Bluetooth reader and an app. To put it simply, the cartridge contains carbon nanotubes（纳米管） that react to lead. This reaction is then registered by the Bluetooth reader, which sends a signal to a mobile app that can tell you immediately if your water is safe to drink.

Rao appropriately named the device Tethys after the Greek goddess of fresh water, and is hoping to make a little improvement to get the device on the market. While we may not be aware of any lead pollution present in our aging pipelines, lead poisoning can cause delays in physical and mental development. With Rao believing that the “purpose of science is to make a difference”, her incredible invention could make a difference to millions of people in the United States.

1.What do we know about Rao’s device?

A. It’s cheap and quick.

B. It’s cheap and inaccurate.

C. It’s expensive and reliable.

D. It’s portable and time-consuming.

2.What made Rao have the idea of designing the device?

A. Her parents’ suggestions.

B. The name of the Greek goddess.

C. Her interest in settling real problems.

D. The water pollution litigation in Flint.

3.What do the carbon nanotubes function as?

A. Sending immediate signals.

B. Recording the reaction results.

C. Detecting the presence of lead.

D. Showing the water quality results.

4.What does the author think of Rao’s invention?

A. It will lead Rao to make a fortune.

B. It will help millions of Americans drink safe water.

C. It will promote the development of science in America.

D. It will soon settle the lead-polluted problem thoroughly.

The Most Direct Solution to Any Problem

When trying to solve various problems in life, an approach I find very useful is to first identify what I’d consider the most direct solution, regardless of how I feel about actually implementing (实施) it. What is the clearest, most direct path to my goal or the most efficient way to get around an obstacle?

Many problems will have multiple direct solutions, but often these solutions will be unpleasant at first glance because they’ll require courage, self-discipline, creativity, or persistence to implement. ________1.________

For example, suppose you want to lose weight. And suppose we can say that one of direct solutions is to eat the same as you’re eating now and increase your exercise output by 500 calories a day. ________2. It may require discipline and persistence, but most people would agree that it will work if you follow through.

Another example: ________3.________ However, you don’t know how that person feels about you. One direct solution would be to simply walk up, explain your thoughts and feelings, and ask if she or he is interested in discussing the possibility of a closer relationship. This will take less than a minute to say, and whatever the outcome is, at least you know where you stand. ________4.________ Anyhow it’s very simple and straightforward.

________5.________ What’s the simplest and quickest way to reach your goal, assuming that you had limitless courage and discipline?

A．Of course this solution may require a lot of courage toovercome the possibility of rejection.

B．But if we can get ourselves to follow through, we know the solutions will actually work.

C．See if you can identify the most direct solution to some of your problems.

D．So the best way to overcome the difficulty is to ask your friends for advice.

E. If you implement this rather simple solution, you’ll lose weight.

F. Suppose you’re interested in starting a relationship with someone.

G. However, the solution implemented does not work.
