3 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

One particularly cold Saturday in January, I was supposed to take our dog out for a walk, but it was so cold that I didn’t want to go outside. Instead, I just opened the door and let the dog out by himself. I kept an eye on him to make sure he would come back inside.

However, another neighborhood dog quickly ran past our house, and our dog sped after to catch him. I hurriedly went to grab my coat so I could follow my dog, and then I rushed outside. Unfortunately, I was already too late, and my dog was nowhere in sight. I walked a few blocks, but I was unable to find him.

Depressed, I returned home. My mother was standing at the door waiting, and she asked me what had happened. “I know I was supposed to walk our dog,” I admitted, “but I thought he would be able to go outside and come back by himself. Now he’s gone and I can’t find him anywhere.”

My mother was very angry with me; she said I should have been more responsible. She decided to help by making some signs. The signs read, “Lost: A big black dog. Please call us right away” and she printed our phone number on the bottom. “Okay, Darrell,” she said, as she handed over those signs, “now go post these on all the street posts.”

My sister and I grabbed the signs and we posted them along our street as well as along the surrounding streets. The whole time, I was incredibly sad and worried about our dog. All I could think about was how cold it was and how cold our dog must be. My sister wanted to go home, so I told her I’d walk her home, but then keep looking for the dog myself.

6 . DNA testing is one of modern medicine’s most significant breakthroughs. Today, anyone can receive personalized information about their genes (基因) and ancestry with just a little saliva (唾液). Now, a Seattle-based company is working to bring equally deep analysis to the trillions of proteins within our bodies.

Nautilus Biotechnology, a company founded in 2016 by Seattle’s Sujal Patel and the San Francisco Bay Area’s Parag Mallick, is developing a device to identify and count 95% of the different types of proteins in a biological sample.

Human cells can contain roughly 20,000 different types of proteins, with crucial functions ranging from digestion to disease protection. Each cell has a varying amount of each protein. The company wants to measure the key machinery (机制) inside cells with a level of detail that has never been done before. Existing tools, it says. can only measure up to 8% of the different types of proteins in blood samples.

So why count proteins at all? Research shows healthy cells and diseased cells have differing amounts and forms of each protein. For example, cancer cells may have more of Protein A than Protein B. Knowing that might help in two ways: First, doctors could look for higher Protein A levels to detect cancer early. Second, researchers could better design drugs to target Protein A.

Nautilus says such protein measurements, which are unique to every person and change throughout people’s lives, will not only help doctors identify more specific forms of disease but also help pharmaceutical (制药) companies find more precise drugs with fewer side effects.

While other companies also are building new protein analysis machines, experts and prospective customers have expressed excitement over Nautilus’s approach. Mallick, chief scientist of Nautilus and the brain behind its technology, is confident: “It’s not every day when you get…to work on something. That’s the opportunity to change all of biology.”

1. What is the Seattle-based company doing?

A．Trying to count the amounts of blood cells.

B．Examining DNA for personalized information.

C．Developing a device to analyze people’s proteins.

D．Revealing more about our ancestry with DNA testing.

2. What makes the invention of the device possible?

A．Precise drugs are guaranteed.	B．Cell analysis techniques develop fast.
C．Proteins are much easier to be analyzed.	D．Protein amounts and forms vary from cell to cell.

3. In which area will the device be helpful?

A．Disease monitoring and machine design	B．Disease detection and drug development.
C．Disease prevention and targeted treatment.	D．Disease treatment and side effect prevention.

4. Which of the following is a suitable title for the text?

A．Combining DNA Testing with Protein Analysis	B．Setting a New Example of Medical Solution
C．Creating Opportunities for Changing Biology	D．Analyzing Proteins for New Medical Breakthrough

8 . Procrastination (拖延) makes people live under constant stress. Making changes will lead to positive results, like relieving stress and increasing the quality of work, family time and joy.     1     Here are some ways to beat procrastination.

◆Acknowledge the need to change.

If you’re a master procrastinator, stop making excuses and acknowledge the reasons why procrastination is bad.     2    

◆Identify and understand your feelings.

You may feel fearful about the size of a task, proud of your productivity, and anxious about your time.     3     However, could you break a huge project up into manageable tasks? Might you need to say “no” more often to give the proper time and attention to the more important things? Can you set a time limit on your break, maybe 15 to 20 minutes?

◆     4    

For master procrastinators, the idea of working too early on a task is stupid. But remember: Just because you start working on something doesn’t mean you have to finish. By starting, you get the juices flowing, allowing you to get more done than you anticipated. Additionally, you increase the quality of your work because every time you revise your thing, it gets better.

◆Use the five-minute rule.

If you find yourself with some free time and you need to convince yourself to start working on a difficult task, follow the five-minute rule. Force yourself to work on a task for just five minutes, with the understanding that you can quit after five minutes if you like.     5     And it will often turn into much more than five minutes. But even if it doesn’t, you’ve done the hardest thing of all: Gotten started.

So, remember: Fighting procrastination is a life-long battle. But it’s a winnable one.

A．But how to?

B．Work on stuff earlier.

C．What are the possible results?

D．These emotions are quite natural.

E．Pay special attention to the quality of your work.

F．This simple mental trick is usually just to get you started.

G．Otherwise, you won’t be convinced there’s a need to change.

9 . On July 14, 2017, Maryam Mirzakhani, Stanford professor of mathematics and the first female winner of the Fields Medal in Mathematics, died at the age of 40.

The news was especially hard-hitting for a generation of younger academics who have always held Maryam as a role model whose example is helping redefine women’s status in science and especially mathematics. What was fun was that

Maryam always tried to avoid the media’s spotlight. Her modesty (谦虚) and simplicity despite being the first woman to gain such high status in the world of mathematics — winning what’s often called the “Nobel Prize of math” — stood out to those who knew her.

Maryam originally wanted to be a writer, a passion of hers that never faded away even during her postgraduate studies. However, she found an even greater joy in how rewarding it felt to solve mathematical problems. As a student, she was the first female member of Iran’s national team to participate in the International Math Olympiad (IMO), and she won two gold medals in two years — still a record.

She received her bachelor’s degree in Iran and later studied at Harvard. In 2014, Maryam was recognized with the Fields Medal, the highest-ranking award in mathematics. Her work focused on curved surfaces like spheres (球体). Her achievements have applications in other scientific fields including engineering and material science. Unfortunately, at that time she was already tackling the breast cancer.

Maryam’s legend (传奇) may continue to grow after her early death. Still only 20 percent of full-time math teachers at U. S. universities are women. The example of a woman who rose to the top of this still very male field may help inspire math’s next generation.

In the same way people think of Marie Curie or Jane Goodall as scientific pioneers, Maryam Mirzakhani will go down in history as a trailblazer as well as a mathematical genius.

1. What makes Maryam internationally recognised?

A．Her unfading passion for writing.

B．Fighting against sexual discrimination.

C．Being the first female Fields Medal winner.

D．Coming under the media’s spotlight frequently.

2. What’s Maryam’s attitude towards fame?

A．Resistant.

B．Realistic.

C．Enthusiastic.

D．Doubtful.

3. What can we know about Maryam?

A．She won gold medals for Iran in IMO.

B．She got her bachelor’s degree at Harvard.

C．She applied mathematics to material science.

D．She instructed some female students to reach the top.

4. What does the underlined word “trailblazer” mean in the last paragraph?

A．Talent.

B．Model.

C．Follower.

D．Pioneer.
