Dear Mr. Zhang,
Known that our school is going to set up elective (选修的) English courses, I'd like to give some advices. English Visual-Audio-Oral Course is a good choice. Most of us are interested at English videos and songs, that provide us with great images and beautiful music to listen to. As result, we can enjoy some local customs and singing English songs with joy. In addition, we need to improve our oral English. When we are always learning English, we may not be able to make a fluent speech. We can't easy communicate with others like native speakers. That is why I suggested taking a Speech Course. I'll be glad that if you can consider my suggestions.
Yours
Li Hua

How to overcome challenges in your life
We all face tough and difficult challenges in life. To overcome challenges you need to have that “never quit” attitude in life. If you develop it, you’ll overcome quite a bit.
Motivate yourself. Say “YES, I CAN.” The challenge should bring out the best of you in this situation. Slow it down, and think that process through. 1. If you develop that mindset (心态), you’ll get it done.
2. Remain calm when you’re facing serious troubles and problems in life. You have to recollect yourself, and calm down. You can’t solve problems when you’re panicking. Take a deep breath, relax, and slow it down. Think things through calmly.
Let failure and fear fuel you in a positive way. Everyone fails at times. If you fail the first, second, or third time, don’t give up. 3. Learn what made you fail at overcoming these challenges.
Simplify the challenge you’re facing. Make the challenge easier than it is. 4. As you get through each step, you develop more confidence and you believe you can get it done, and then you will.
Stay positive and confident. 5. You have to find out all the ways you can use to overcome it, and put them to full use with all your effort. It’s our own mental stability that’s the difficult part. When you do it mentally, you’ll actually be able to do it.
A. Stay calm and cool headed.
B. Think the best, not the worst.
C. Start by breaking it down into steps.
D. To overcome a challenge, you have to believe you can really do it.
E. Most people will avoid any challenge, because they’re scared of failing.
F. Develop that confidence in saying there’s no way you’re going to fail at this.
G. Pick yourself up, and learn from why you’ve failed, and move on in a positive direction.
It‟s no secret that American infrastructure is aging. Concrete(混凝土) structures, in particular, are in desperate need of repair.
Cracks (缝隙) are very common due to various chemical and physical phenomena that occur during everyday use, which can be quite harmful as they provide an easy route in for liquids and gasses and the harmful substances they might contain. But continuous repair work is difficult because it usually requires a huge amount of labor and investment. So since 2013, I‟ve been trying to figure out how these harmful cracks could heal themselves without human involvement. The idea was originally inspired by the amazing ability of the human body to heal itself of cuts, bruises and broken bones. In the same way, can we provide necessary products to concrete to fill in cracks when damage happens?
My colleagues from Binghamton University and I have found an unusual candidate to help concrete heal itself: a fungus (真菌) called Trichoderma reesei. We initially screened about 20 different species of fungi in order to find one that could stand the difficult conditions in concrete. Of all the fungi we tested, only T. reesei could survive this environment. Despite the sudden PHincrease, its spores (孢子) developed into threadlike things and grew equally well with or without concrete.
We propose including fungal spores, together with nutrients, during the initial mixing process when building a new concrete structure. When the unavoidable cracking occurs and water finds its way in, the sleeping fungal spores will start to grow. They then will work as an activator within the calcium-rich conditions of the concrete to promote precipitation (析出) of calcium carbonatecrystals. These mineral deposits can fill in the cracks. If cracks form again and environmental conditions become favorable, the spores could wake up and repeat the process.
Our research is still in the initial stage and there’s a long way to go to make self-healing concrete practical and cost-effective. But the scope of American infrastructure’s challenges makes exploring creative solutions like this worthwhile.

2.What do we know about T. reesei?

B. It can bear the tough conditions in concrete.
C. Its spores will be useless after one repair.
D. It poses potential risks to environment.
