最近很苦恼,很苦恼……我被一件事惹的愁眉不展,闷闷不乐,不知所措。

Recently, I have been very distressed, very distressed... I have been troubled by something that has made me frown, depressed, and at a loss.

而令我苦恼事是我要做个科学小实验,苦思冥想后,决定做个给手机充电的电源。找到两节5号电池,用纸卷好当作电源,两头引出电线,先用小电灯泡试验电池是不是有电,电线是不是通畅,经过实验小电灯泡亮了。于是开始连接手机充电器准备给手机充电,发现充不成。网上搜了一下,才明白电池里的电是直流电,而手机充着电是用交流电,必须配备个整流器才能用,我瞬间心乱如麻。

And what troubles me is that I want to do a scientific experiment. After much contemplation, I have decided to make a power source for charging my phone. Find two No. 5 batteries, use a paper roll as a power source, and lead out wires at both ends. First, use a small light bulb to test whether the batteries are charged and whether the wires are unobstructed. After the experiment, the small light bulb lights up. So I started connecting my phone charger to charge it, but found that it couldn't be charged. After searching online, I realized that the electricity in the battery is direct current, while the phone is charged with alternating current and requires a rectifier to use. I was instantly confused.

去哪里才能找到这个东西呢?我问爸爸才知道,家附近没有卖这种东西的,要买的话只能走街窜巷去打听,唉!我只能拿出科学书在里面翻找,看再有没有好的实验,结果从一年级翻到四年级也没找到心满意足的实验。

Where can I find this thing? I only found out when I asked my dad that there is no such thing sold near my house. If you want to buy it, you can only wander around the streets to inquire. Sigh! I could only take out a science book and search inside to see if there were any good experiments, but I couldn't find any satisfactory experiments from first grade to fourth grade.

我心急啊!新冠疫情屡禁不止,此起彼伏,闹得人心慌慌,不能订快递!不能去商场!我心急如焚啊!去那里都全副武装,担惊受怕。哎,我真的好苦恼!什么也做不成,这个科学小实验,难道是让我做无米之炊?

I'm in a hurry! The COVID-19 has been repeatedly banned, one after another, causing people to panic and cannot order express delivery! You can't go to the mall! I'm so anxious! Go there fully armed and fearful. Oh, I'm really distressed! Can't do anything? Is this scientific experiment making me cook without rice?

苦恼就象一堆乱麻,越是想早点捋顺,越是乱的厉害。

Distress is like a pile of chaos, the more one tries to sort it out early, the more chaotic it becomes.

我好苦恼啊!

I'm so distressed!
