1 . Babies made from three people approved in UK

Babies made from two women and one man have been approved by the UK’s fertility regulator. The historic and controversial move is to prevent children from being born with deadly genetic diseases.

Doctors in Newcastle — who developed the advanced form of In Vitro Fertilization or IVF (人工授精) — are expected to be the first to offer the procedure and have already appealed for donor eggs. The first such child could be born, at the earliest, by the end of 2017.

Some families have lost multiple children to incurable mitochondrial (线粒体的) diseases, which can leave people with insufficient energy to keep their heart beating.

The diseases are passed down from only the mother, so a technique using a donor egg as well as the mother’s egg and father’s sperm has been developed.

The resulting child has a tiny amount of their DNA from the donor, but the procedure is legal and reviews say it is ethical (伦理的) and scientifically ready.

“It is a decision of historic importance,” said Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority (HFEA). “I’m sure patients will be really pleased by what we’ve decided today.”

But some scientists have questioned the ethics of the technique, saying it could open the door to genetically-modified(转基因) ‘designer’ babies.

The HFEA must approve every clinic and every patient before the procedure can take place. Three-person babies have been allowed only in cases where the risk of a child developing mitochondrial disease is very high.

Prof Mary Herbert, from the Newcastle Fertility Centre, said, “It is enormously pleasing that our many years of research in this area can finally be applied to help families affected by these devastating diseases”.

“Now that we are moving forward towards clinical treatments, we will also need donors to donate eggs for use in treatment to prevent affected women transmitting disease to their children.”

Prof Sir Doug Turnbull, the director of the Welcome Centre for Mitochondrial Research at Newcastle University, said, “We are delighted by today’s decision. We will also provide long-term follow up of any children born.”

NHS England has agreed to fund the treatment costs of the first trial of three-person IVF for those women who meet the HFEA criteria, as long as they agree to long-term follow up of their children after they are born.

2 . Do you want to live with a strong sense of peacefulness, happiness, goodness, and self- respect? The collection of happiness actions broadly categorized as "honor" help you create this life of good feelings.
Here's an example to show how honorable actions create happiness.
Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk's mistake, we would drive home with a sense of sneaky excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.
Then, what is it to do with our sense of happiness?
In the first case, where we don't tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot lie trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased.   Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility.
There is a beautiful positive cycle that is created by living a life of honorable actions. Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it's easy to think and act honorably again when we're happy. While the positive cycle can be difficult to start, once it's started, it's easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.

4. How will we feel if we let the clerk know her mistake?

A．We'll be very excited.	B．We'll feel unfortunate.
C．We'll have a sense of honor.	D．We'll feel sorry for the clerk.

There was a noticeable touch of__________ in the way he seemed to be doing things— __________the windscreen, then standing back to admire it; scrubbing the wheels and __________, standing back to see what they look like after the scrub.

It was a __________ to learn, I felt. At no age need one have to beg for a __________if one has good health and is willing to work hard. For a while I felt ________ of myself.

6 . On Dec.17, 2019, Andrew noticed a balloon’s string was______to a piece of paper. “Dayami,” it read on one side, in a child’s______. Andrew turned the paper over. It was a Christmas______. He wondered whether he could find the girl who had sent this one.

It would be difficult, ______Andrew had a few clues. About 20 miles to the southwest, just across the______, was the city of Nogales, Mexico.

“Based on the prevailing wind, I was pretty sure that’s______it came from,” he said.

On December 22, 2019, he decided to send a private Facebook______to a radio station in Nogales.

To his______, the next morning, Andrew______to one message from the radio station: They had______Dayami, an eight-year-old girl, and her family, who indeed lived in Nogales. Would they be______to arrange a get-together at the radio station?

Andrew went with his wife to Walmat. They bought just about everything on Dayami’s list______the dollhouse (it was sold out). They also bought a few other toys, as they had learned that Dayami had a younger______, four-year-old Ximena.

Then the Andrew drove for 45 minutes, crossing the border into Nogales, and finally met two very______little girls.

Their parents______to the Andrew that Dayami had been writing a letter a Santa and sending it by______for years, but this was the first time anyone had found the note.

“Their eyes were______open with wonder,” Andrew said of the two sisters’ reaction. “Like, ‘Oh, my gosh, this really did work!’”

“It was a beautiful, beautiful experience,” Andrew said. He paused “Quite______for us,” he added.

Andrew, 61, has lived in southeastern Bisbee for more than three decades. Ten years ago, he and his wife______their only child, a son. They have no grandchildren.

“We are now have friends for life,” Andrew said. “And, for a day, that border fence with its concertina wire______away.”

7 . Homestay provides English language students with the opportunity to speak English outside the classroom and the experience of being part of a British home.

What to Expect

The host will provide accommodation and meals. Rooms will be cleaned and bedcovers changed at least once a week. You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.

Accommodation Zones

Homestays are located in London mainly in Zones 2, 3 and 4 of the transport system. Most hosts do not live in the town centre as much of central London is commercial and not residential (居住的). Zones3 and 4 often offer larger accommodation in a less crowned area. It is very convenient to travel in London by Underground.

Meal Plans Available

◇ Continental Breakfast

◇ Breakfast and Dinner

◇ Breakfast, Packed Lunch and Dinner

It’s important to note that few English families still provide a traditional cooked breakfast. Your accommodation includes Continental Breakfast which normally consists of fruit juice, cereal (谷物类食品), bread and tea or coffee. Cheese, fruit and cold meat are not normally part of a Continental Breakfast in England. Dinners usually consist of meat or fish with vegetables followed by desert, fruit and coffee.

Friends

If you wish to invite a friend over to visit. you must first ask your host' s permission. You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy.

Self-Catering Accommodation in Private Homes

Accommodation on a room-only basis includes shared kitchen and bathroom facilities and often a main living room. This kind of accommodation offers an independent lifestyle and is more suitable for the long-stay student. However, it does not provide the same family atmosphere as an ordinary homestay and may not benefit those who need to practise English at home quite as much.

8 . In August 2017, Southeast Texas was underwater. Hurricane Harvey dumped five feet of rain in some areas, and nearly six feet of storm surge(风暴潮) made sure that the water had nowhere to go but into the houses, businesses, and lives of thousands of residents. More than 100 people died and $125 billion in damage was recorded before the waters went down weeks later.

About 30 miles due west of Houston, Katy, Texas, a former farm town of 18,000 residents, took a hard hit. Nearly 700 of its homes and 80 businesses were damaged or destroyed. But locals didn't wait for the rain to stop before opening their doors, refrigerators, and wallets to first responders, neighbors, strangers, and even pets.

Beaver Aplin, owner of the popular Buc-ee's chain of convenience stores, was preparing for the grand opening of his newest location just outside Katy. The 50,000-square-foot store was fully stocked with everything from food, water, and toiletries to batteries and Band-Aids. When the storm hit, Aplin opened the store early without thinking twice. He put the word out to first responders, telling them to take what they needed, free of charge.

Meanwhile, locals ran, drove, and paddled to rescue their neighbors stuck in the water. When the water was too deep, rescue came by boat. Pat Lester drove his air-boat into town from his home on the outskirts(郊外). He had seven life jackets, so he scooped up seven people at a time, starting with pregnant women, the elderly, and anyone who was ill.

These are just a small part of the stories of heroism that came out of Katy and all over Texas during one of the worst natural disasters the country has ever seen.

Even first responders coming from outside Katy could instantly feel the town's selfless spirit. ''We helped people in lots of other areas too, but Katy was amazing. Neighbors were going from house to house checking on people and helping everyone they could, '' David Scherff told Katy Magazine.

9 . To help self-driving cars drive safely, scientists are looking to an unlikely place: the sea. A new type of camera inspired by the eyes of mantis shrimps(螳螂虾) could help autonomous vehicles better assess their surroundings, researchers report October 11 in Optica. The camera has roughly half a million sensors that each capture a wide range of light and dark spots within a single frame, somewhat similar to how mantis shrimps see the world.

The researchers wanted to ''imitate the animals' ability to detect a wide range of light intensities(强度), ''says co-author Viktor Gruev, a bio-engineer at the University of Illinois at Urbana-Champaign. The shrimps’ visual system allows them to see both light and dark areas while moving in and out of dark cracks in shallow waters, he says.

The newly devised camera can take in a wider range of light intensities, measured in decibels (分贝), than other digital or polarization cameras. Previously, the best polarization cameras operated with a dynamic range of about 60 decibels; the new one works within a 140 decibel range, resulting in a clearer mapping of objects in the same frame.

Depending on the maker, autonomous vehicles currently use a mixture of methods to map the world around them, including lidar (light detection and ranging equipment), cameras and GPS. But the cameras currently guiding autonomous vehicles aren't good at handling sharp lighting transitions and have trouble detecting features in foggy weather. Because the new cameras are small and use many of the same parts as common digital cameras, Gruev says they could cost as little as $10, which means they are car-makers' best choice for their autonomous vehicles.

1. What do we know about the new cameras after reading the article?

A．They enable cars to go through cracks without trouble.

B．They use totally different parts from common cameras.

C．They have already been widely used on self-driving cars.

D．They see the surroundings by detecting the light intensities.

2. How does Viktor Gruev feel about the cameras' practical use on self-driving cars?

A．Hopeful.	B．Uncertain.
C．Worried.	D．Modest.

3. What is the best title for the article?

A．Self-driving cars are already on their way.

B．Bioengineering paves the way for our future.

C．Mantis shrimps bring inspiration for new cameras.

D．The popularity of self-driving cars depends on cameras.
