Cancer is a leading cause of death around the world.

When it comes to cancer, the sooner you know you have it, the better your chances of surviving are.

A new blood test could change the way doctors and researchers find cancer in patients. Researchers say the test could provide some hints of the early forms of the disease.

Gareth Jenkins is a professor at the University of Swansea. He says he and his team did not look for cancer. They instead looked for a by-product of cancer, mutated (突變的) red blood cells. They looked for, what Jenkins calls, the collateral (附帶的) damage of cancer—the damage left by the disease.

“In this blood test we don’t measure the presence of cancer，we measure the presence of mutated red blood cells which are the collateral damage that occurs—a by-product of the cancer developing.’’

The researchers used normal laboratory equipment to perform the tests. This equipment looks for changes in the structure of millions of red blood cells. Those mutated cells lack a surface protein (蛋白質(zhì)) that healthy cells normally have.

“The goal of the test is looking for very rare cells which have picked up a mutation. The number of mutated red blood cells in a healthy person is around 5 or so mutated cells per million; so, you have to look at millions of red blood cells to discover those rare events. The number increases in cancer patients—it goes up to 40 or 50 on average.”

The researchers tested blood from about 300 people, all of whom have cancer of the esophagus (食管). Patients with esophageal cancer have high levels of mutated red blood cells. Jenkins says that at this point he is not sure if other cancers would produce similar results.

The hope is that the new test could one day become part of commonly used medical methods to find out if a person has cancer. These new technologies could save millions of lives.

A. Deaths. B. Experiences.

C. Signs. D. Kinds.

2.Healthy people and patients with esophageal cancer are different in of mutated red blood cells.

A. the size

Often during a conversation I’ll get the question. “Where have you traveled?” I’m always a little hesitant to answer because travel is typically viewed as going somewhere abroad and my travels haven’t exactly consisted of going abroad. 1. Travel is experienced when you ...

1. Step out of your comfort zone.

Have you ever heard of the saying “Life begins at the end of your comfort zone.”? The same goes for travel. You cannot travel unless you get planning! But the act of stepping out of your comfort zone doesn’t just stop once you’ve finished planning. 2. You have to let yourself be involved in whatever experience may come your way to really experience the beauty of travel.

2. Open your mind.

Wherever your destination may be, you need to arrive with an open mind. You’re going to be experiencing new sights, cultures, foods, maybe even languages. 3. Be open to trying new things, be open to understanding and be open to accepting. More importantly, open your mind to learning. You will learn so much more than you’ve ever dreamed of learning in a classroom.

3. 4.

Through experience, travel can really help you reflect on who you are as a person, what sights your heart responds to and what cultures have powerful influences on you. You begin to realize through the different experiences you find just how capable you really are. Traveling is not about the journey to the destination; it’s about the journey you take into yourself. 5.

A. Discover yourself.

B. Experience something new.

C. It continues throughout your travels.

D. Travel can be experienced in the next city, state or country.

E. You become equipped with a new pair of eyes and a more accurate sense of self.

F. What I want to share with you is that travel is not experienced by your destination.

G. You can’t learn to see the beauty within them unless you view them with an open mind.

Everyone likes to have friends 1 are trustworthy. When what we say matches what we do, we earn trust and friendship. On the contrary(與此相反), once we break our word, nobody will ever trust 2 again. For example, if you are 3 untrustworthy worker, you are less likely to get a promotion. Therefore, the 4 (important) of keeping one’s word cannot be stressed too much.

I once had the unpleasant experience of someone breaking his promise to me. Last month, everyone in my class had to gather at school 5 6:30 AM for our 6 (graduate) trip. My friend Ben asked me 7 (meet) him at McDonald’s at six, but he never showed up. I was 8 (depress) that when I called him, he told me he was already at school. I 9 (rush) straight there, but all my classmates still blamed me for delaying the trip. After that, I ended my friendship with Ben because I don’t need 10 (friend) who can’t keep their word.

I used to be a physician at a hospital. I often treated children who had poisoned by medicine with older family members. The children didn’t know the medicine was danger; they just knew it tasted sweetly. Children easily open the bottle what we now use in China.

Some days before, I talked about medicines with an American. He showed me a sort of plastic bottle. The design was quite simple and I’m sure our Chinese factories can produce these bottles. The top of the bottle can be opened by pressing down on them while turning, which is difficult for most young children to do so, though grown-up can open these bottles very easily. I’m certain that the expense of making such tops would be very small. As a doctor, I’d love to see this doing. And most parents would be grateful.

Sincerely yours

iOS 10 The world’s most advanced mobile operating system.

Easy to Use

From the moment you pick up your iOS device, you’re up and running. Tap your favorite app and get right to work — or play. Swipe from the right side of the Lock screen to quickly pull up your camera. Scroll through thousands of photos in seconds. Everything about iOS is designed to look beautiful and work beautifully.

So smooth and responsive you won’t even notice it. And that’s the point.

Because iOS is engineered specifically for iPhone and iPad, everything looks and feels incredibly fluid. iOS uses a framework called Metal to maximize graphics performance. Whether you’re surfing the web, moving from app to app, or playing the most complex 3D video game, the graphics and responsiveness are amazingly smooth. No other mobile operating system is so effortless and natural.

An OS with a remarkably high IQ.

Siri even works with your favorite apps.

You can ask Siri to send someone a payment using Square Cash, book a reservation through OpenTable, and much more. And the number of apps incorporating Siri is growing every day.

I wonder if my make-up is ok. What will I say to him? Carefully, I stepped out of my car as my date made his way over to me.

“I’ve got you something,” he greeted me with a huge smile on his face. “Something every girl secretly longs for (渴望).” Standing in front of me, he slid something into my hand. I looked down to find candy — but not just any candy — A Sugar Daddy!

I relaxed immediately. This was the funny man I had been talking to. Little did he know, my secret longing was really to make a good impression on him.

A good first impression is important. So, how do you, when you’re meeting someone for the first time, make certain he or she doesn’t get the wrong image of you?

A study concluded that the first 30 seconds make or break the connection between two people when they meet for the first time. Another study conducted by UCLA found that “people evaluate one another by using the three V’s: visual (appearance), vocal (voice) and verbal (what you say).”

Before you head out on your next date to meet someone new, let’s concentrate on these areas:

●How others will see you. (Visual) Are you dressed well? Do you look like this date is important to you? Did you take some time with your appearance? Watch your manners: people don’t like bad manners.

●How others will hear you. (Vocal) Is your voice too soft? You might come across as insecure. If you speak softly, make an effort to speak clearly — don’t make your date have to work to hear you.

●What others will hear you say. (Verbal) People have a natural desire to connect — let them know you’re interested in what they have to say by repeating it back to them. Don’t say the same thing everyone else is saying.

1.What would be the best title for the text?

A. Good measures to communicate with others

B. How to make friends with others

C. How to enjoy yourself in your life

D. The importance of a good first impression

2.According to the text, when you want to make friends with someone, ______.

A. you should try to master the first few seconds

B. you should talk as much as possible

C. you should wear strange clothes to give him or her a deep impression

D. there is no need for you to treat it seriously

3.Which of the following belongs to the description of “Vocal”?

A. Dress yourself very well. B. Spend some time on your appearance.

C. Speak carefully and clearly. D. Repeat the same thing several times.

Living among trees, plants and flowers can fill your life with beauty. And if you are a woman, it can also help you live longer. Researchers found that women who live in homes surrounded by plants appear to have lower death rates than women who live in areas with fewer plants.

Researchers at Harvard University’s T.H. Chan School of Public Health reported the finding. They looked at the information from one of the largest and oldest investigations of the women’s health: the Nurse’s Health Study. It began 40 years ago. It now has information on nearly 200,000 women.

For the new study, the team looked at the death rates of more than 100,000 women between the years 2000 and 2008. Then the researchers compared the death rates of these women to the plants around their homes. The researchers also considered other things, such as the age of the women, money they earn and race. They also looked at whether or not the women smoked.

The study found that the death rate among women who lived in the greenest spaces was 12% lower than those from the least green areas. The researchers were surprised to find such a strong connection between high vegetation levels and low death rates.

The study suggested that living among trees, flowers and other plants lowered levels of depression. Researchers said women in greener areas spent more time with other people and exercised more. It is common knowledge that plants can help the environment in many ways. The new finding also suggested ways to the government and the city planners to grow even healthier living areas.

1.How did the researchers divide the women in the study?

A. By their money. B. By their different ages.

C. By their habit of smoking. D. By the number of plants around them.

2.It can be inferred from the last paragraph that ________.

A. more and more women will plant trees

B. it will be a must to build houses with trees around

C. the new finding may influence future living conditions

D. the government will take action to make women healthier

3.What is the best title of this passage?

A. Women should grow flowers at home

B. Plants may help women live longer

C. Women must exercise more to keep healthy

D. The bad environment causes high death rates
