1 . There is growing evidence to show that our past knowledge about Mars was not always the case. Now European researchers say they have discovered the first evidence of a huge groundwater system that once existed below the planet’s surface.

A new study was carried out by Francesco Salese and his team, who studied images of 24 deep craters (n.弹坑) in the northern half of the Red Planet. These pictures were captured by ESA’s Mars Express orbiter (n.宇宙飞船), which was launched in 2003. The study provides the first geological proof that Mars once had a “planet-wide groundwater system.”

According to Salese, scientific evidence already suggests Mars was once a watery world. His team says the images showed that large amounts of successive groundwater activity connected the areas they studied. Evidence of basins and coastlines was also found on the surface of Mars, supporting the idea that water was once present. He added that all the basins seemed to reach about the same height.

Scientists have yet to find out what happened to all that water. And the complex history of water on Mars has linked to whether or not life ever existed on it. During the latest study, researchers also discovered evidence of minerals within some of the identified (adj.被识别的) bodies of water.

The researchers say the findings adds weight to the idea that the water basins on Mars may have once held the materials required to support life. Some of this material could still be buried on Mars, providing possible evidence of life during future exploration. Francesco Salese believes the latest findings could also help us learn new things about our own planet.

2 . Gear for Sleeping Outdoors

Whether you’re camping or backpacking, how can you increase the odds (n.机会) that you’ll sleep soundly in the outdoors? A good start is to have the right gear:

Sleeping bag: Choose a sleeping bag with a style and temperature rating (n.等级，级别) appropriate for your destination.

·Car camping bags are typically cut wider, offering homelike and more roll-around room but less efficiency for retaining body heat (not so good on extra-chilly nights).Some rectangular (adj.长方形的) styles can be unzipped (adj.未拉上拉链的) to use as a quilt on milder nights.

·Backpacking bags are mummy shaped for a closer, warmer fit, and are usually lighter in weight. Many are filled with goose or duck down, which compresses (v.压缩) more readily than synthetic( adj.合成的) fill.

Sleeping pad: There are three types of sleeping pads — self-inflating (adj.充气的), air and closed-cell foam (n.泡沫塑料). When car camping, weight is not an issue, so you can enjoy a thicker, wider pad or mattress for comfort. When backpacking, weight is crucial, so a super-lightweight air pad or closed-cell pad may be your first choice.

Pillows: Bring one from home or use a small foam or inflatable camp pillow. Some sleeping bags have a pocket to hold a pillow or folded up clothing, such as a down jacket or fleece sweater.

Eye mask and earplugs: Eye masks are especially helpful when camping in northern latitudes (n.纬度) in summer or in campgrounds with surrounding light. Earplugs block out noises ranging from your tent mate’s snoring to rustling sounds in the bushes.

1. Why do people choose car camping bags?

A．They have goose or duck down fill.

B．They are easy to carry in a car.

C．They are more comfortable.

D．They are good for retaining body weight.

2. What kind of sleeping pad can people choose when backpacking?

A．a wider pad.	B．Closed-cell pad.
C．a thicker pad.	D．Super-heavyweight air pad.

3. What do people use the earplugs for?

A．Blocking out noises from tent mate’s snoring.

B．Reducing noises from the wild animals.

C．Stopping the ambient light.

D．Protecting the ears from being hurt by the rustling sounds.

3 . Secrets, whether they’re juicy, shocking or just plain funny, nothing compares to the thrill of opening up or listening to a friend’s confession (n.坦白). When a pal bares his heart to you, you can’t help but feel trusted and special. In fact, you’re a lot more likely now to tell him something you wouldn’t tell just anyone. When you’re first getting to know a new friend, start with small secrets.

No secret is ever 100 water-proof, but you can take steps to prevent getting your feelings hurt. First, when something you’re telling a friend is a secret, always say so. Every time when you share something confidential (adj.保密的), tell her that this is “for your ears only.” Also, don’t assume (v.假定,认为) someone will keep your secrets just because you know some of hers. Some people just have a tendency to blurt things out, which is why it pays to get a feel for how good a secret-keeper your friend is. Finally, make sure you get a reputation as someone who takes secrets seriously.

It’s not worth breaking a promise to a friend, but if a secret is too big for you to carry alone, you have a responsibility to tell someone. There are probably a few details about your life that you don’t feel like sharing, even with your closest friends. If the secret isn’t hurting you or your friendship, silence is golden. If you’re hiding something big and constantly worrying about your secret being leaked, it may be time to just spill (v.溢出) your beans. Taking control of a secret that’s eating you up inside isn’t easy.

So it seems clear that knowing when to let the secret out and when to zip your lips will help you a lot.

9 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

An undersea tunnel (n.隧道) of a high-speed railway was completed in South China on Friday,    1     (set) a new record in the construction of high-speed railway tunnels in China.

The Zhanjiang Bay (湛江湾) Undersea Tunnel, a key project of the Guangzhou-Zhanjiang High-speed Railway,    2     (complete) after 33 months of construction, marking a significant milestone in the construction of the new railway.

The Zhanjiang Bay Undersea Tunnel spans (v.横跨)    3     total length of 9,640 meters. It is designed as a single tunnel with double tracks, crossing the seabed of the Zhanjiang Bay and the urban area of Zhanjiang. It crosses a 2,500-meter sea section and a 5,051-meter section of land.    4     (especial), the tunnel is China’s    5     (long) single-headed undersea high-speed railway shield tunnel (盾构隧道), showcasing the country’s remarkable engineering techniques.

“Single-headed shield (单头盾构) refers to the method of using a single tunnel boring machine (隧道掘进机)     6     (dig) continuously from one end to the other,” said Yin Yihao, an engineer from China Railway’s 14th Bureau Group, which was responsible for the tunnel’s construction. Yin added that the traditional methods were not applied in the Zhanjiang Bay Undersea Tunnel due to the complicated geological conditions and    7    the single-headed shield tunnel was    8       (safe) and more efficient in this case.

Wu Chunzhao, a senior engineer of the China Railway Design Company,    9     (explain) the reason for building an undersea tunnel instead of a bridge. “Building a tunnel preserves (v.保护) the beautiful urban skyline of the Zhanjiang Bay,    10     avoids the impact of the project on the marine (adj.海洋的) ecological environment,” he said. Wu also noted (v.指出) that a bridge will affect the large ships’ navigation, but the tunnel will not do this.

The tunnel is a key project of a high-speed railway linking Guangzhou and Zhanjiang in Guangdong.

Alan Robinson and Walter Macfarlane have been friends for 60 years. Born in Hawaii 15 months apart, they met in the sixth grade and played football together at a Honolulu prep school.

Macfarlane never knew his father, and Robinson was adopted. Separately, they sought answers about their ancestry (n.祖先，血统). Macfarlane turned to family history and DNA-matching websites to learn more about it after unsuccessful searches on the internet and social media. “So then we started digging into all the matches (n.匹配) he started getting,” said his daughter, Cindy Macfarlane-Flores.

A top match - someone with identical X chromosomes (n.X染色体)- had the username Robi737.Robison’s nickname was Robi and he flew 737s for Aloha Airlines, Macfarlane-Flores said.

It tuned out Robinson used the same website to find answers about his family. They later learned they have the same birth mother.
