They think, Okay, so I know an egg  weighs 20 grams.. But the sentence is not just saying it weighs 20  grams. It says it weighs 20 grams AND half an egg. If you read it  backwards, you would understand. Let's try, An egg weighs half an  egg and 20 grams.. Two halves make one.
Diamond Valley Lake lies between two mountains in California's Inland Empire tourism region. The 4,500-acre lake is Southern California's newest and largest reservoir. It has only been at full pond since 2002 and already has been crowned the Jewel of California lakes, with a reputation for excellent fishing.
The âHidden Gemâ of the San Bernardino Mountains, Green Valley Lake is, at 7000Â´, a higher resort community than either Lake Arrowhead or Big Bear. This âbest kept secret on the mountainâ is secluded (nearly four miles away from State Highway 18), and surrounded by National Forest. For all these reasons it has remained small, picturesque, and uncrowded. Green Valley Lake has something going on all the time. For a little town, we sure stay busy.
